I have to credit my wife again for not only the project saving idea, but also for all her support with the channel. These videos wouldn't be possible without her. Join us again on Friday September 16th at 10am EST for what will hopefully be the conclusion to this project. Fingers crossed for no more mistakes. Or at least no more BIG ones. Thanks for watching!
Perhaps she should have her own channel??? Or at least feature her in one of yours. As well, helping your followers to get to know you by making a video about your background, hers, grandfather, etc. would be nice. I really enjoyed your first video that told a bit about you and your grandfather.
As a fellow toolmaker and engineer, I think it's great that you don't leave out the mistakes. Anyone watching can learn from that. The adapter looks great.
When we are talking about misstakes, there are 2 different people. The ones who hide it, and the ones who are talking to colleagues about best way to fix it. I have seen both at my work. Everyone makes a misstake sometime.
There's nothing more gut wrenching than screwing a part, and nothing more satisfying than the bodgery required to salvage it actually coming out looking professional. As a machinist in a repair environment rather than manufacturing, I think I've found a new favorite channel.
Dude, I've been following you from the beginning of your channel and I just want to say, as a none machinist viewer, that your channel is a wonderful contribution to the machinist community in TH-cam. I'm sure you'll grow and have a very successful channel. Thank you for all the wonderful videos. Well done.
@@InheritanceMachining Obviously you needed more heat, and you need to heat the entire part, otherwise the rest of the part is just going to suck up the heat and the bore isn't going to expand at all or evenly especially since it os right on the edge. Set an inside mic or a telescope gauge to .003 or .005 over the size of the sleeve and check as you heat to make sure the gauge slips through, then your sleeve should fall right in.
Making a major mistake is a frustrating and sometimes panic-inducing experience. The way you recovered from it is nothing short of inspiring. As always, you produce professional grade, beautiful tools. I enjoy your videos a lot, thank you for making those.
Drills are made to cut on the end while end mills are for side cutting. When a flat bottom hole is needed, drill to finished size then follow with a flat bottom drill. But you knew that already. Keep up the good work.
I’d almost be jealous of what you’ve got going on. Hell, I am. But I think your’s are the right hands the legacy has chosen. Your videos are superb. Your missus rocks. The machines are art. And your work…..is…all of these things
I jump around a lot and rewatch the older builds but this video has a special place for me as this was the video that was recommended and is the reason why i began watching this channel almost 2 years ago at this point. And I have no plans on stopping that is for sure
.002" is quite a heavy press for a 1inch sleeve. I use the .0005" per inch of diameter rule. .001" per inch for things that will have a lot of load. Nice save with the sleeve and boring head and a beautiful part!!
Alongside my mechanical engineering degree, I plan to become competent at machining (took my first few machining courses not too long ago). Watching your videos has made me realize that I have a long long long way to go and to be incredibly patient when I'm working away. Subscribed!
You are very kind, but I'm still a beginner myself. There are honestly endless things to learn in this field so you will never get bored, I'm sure. Thanks for the support!
Just food for thought. I wanted to mount a four-jaw independent chuck to a rotary table to hold oddly shaped objects. I was going to make an adapter plate, but lazy me, I decided to do it differently. This was an 8" table, and I wanted an 8" chuck for it. Using the T-slots would have required a rather thick plate. Since it is common for a 4-jaw independent flat-back chuck to be mounted to a spindle adapter with bolts from the front of the chuck, I simply drilled and tapped four holes in the top of the rotary table. I did take the rotary table apart to make sure I didn't hit anything important when I drilled and tapped the front. A simple solution. If I want a 3-jaw scroll, I'll just mount it in the 4-jaw.
I am a woodworker. We do the same thing in different mediums, but I have to live with 'wood moves'. I love seeing a craftsman at work, and your videos are Frist quality. Nice that your wife is involved with problem solving. Team.
As a machining apprentice in my second of three years, this channel is pure gold for me. Thank you for leaving in the mistakes you made, especially in this video it shows how errors and bad ideas cannot only exponentially grow, but also be solved and turned into good.
It still amuses me that a critical step in the process of aligning materials very, very precisely, usually involves wacking it with a hammer. Still enjoying the videos man. Keep em coming!
Beautiful result for this custom part. It may not match every dimension on the drawing, but when you’re done you can update the drawing to match the part. Happens all the time in industry…… even in aerospace companies. If you want to document these changes, just capture what’s change on a “engineering change order” and roll the drawing’s revision letter from NC (no change) to Rev A. 👍👍😎👍👍. Can’t wait for the next installment.
Over here, "A" would be a prior to construction rev. Your construction drawings would be rev 0, with the short description "issued for construction" in the revision block, and the update would be rev 1, probably described as "dimensions updated" and the revisions indicated with a "cloud" drawn around the changes in a light line weight. Interesting just how different standard practice can be.
My father, who worked for Honeywell as a production engineer in their aerospace department, always told me “a craftsman will always make his mistakes look as if they were an actual part of the design” or something very close to that! One of the interesting things about your videos is your willingness to own, or feed to your box of shame, the errors made and how you correct them! Keep up the very interesting commentary!
I'm about your age and built my own machine shop (couldn't inherit it) after going to engineering school. I've been at it 15 years. I don't get a lot of time to work in the shop because after engineering i did medschool and soon i'll be a specialist neurosurgeon. I have a bigger mill, a smaller lathe, and a bigger surface grinder. Its interesting how despite different life circumstances we tend to gravitate towards to this childhood obsession of making things in the shop, even after all these years.
I don't have a bandsaw or sandblaster but I have an ACDC tig welder and my toolroom mill can spin a 350mm disc for parting off stock like a cold cut saw. Originally I wanted a big lathe but i took a mill and smaller lather instead since they were both together at some professor's shop who had to part ways with them due to poor health.
Excellent video Brandon. I can totally relate. I've made plenty of mistakes myself halfway through a complicated part, and more often than not scrapped the part and started over. My hat's off to you not only for sticking with it but also for owning the mistake and learning from it. One of my first projects was a brass gyroscope. I got all the turning on the lathe done, and it came out beautiful....only to get completely eaten up by a 1/2" drill bit while I was drilling the flywheel. As I was punching the 5th out of 6 holes, the bit grabbed and pulled the flywheel right out of my clamps, totally destroying it. A total loss because stupid me didn't want to clamp it down too tight on my mill table for fear of marring the finish. How's that for irony? Regardless, the best lessons are those that sting a little....you never forget what you did wrong and you always remember how you fixed it. Great content and take take care my friend.
Oh man.. the ironic mistakes like that are always the worst! You usually have a gut feeling that what you are doing isn't quite right then it comes back to bite you... been there before too! Also that's exactly right. You could watch all the videos in the world but until you make the mistake yourself and at a cost, you may not truly learn. Thanks again for the support!
Your wife is awesome. Thank God for supportive partners. You did a nice recovery and your mistakes remind me that not everyone gets it right the first try. That is so important. Nice recovery too. You really showed the value and importance of not giving up. Thank you for another great video!
I've learned in my machining career that once I started to calm down relax and slow down my mistakes diminished so glad I do job shop work now vs production work.
I give you a tremendous amount of respect for showing your mistakes along with everything that went right in your videos . We learn so much more from our mistakes than we do from our successful endeavors .
As an electronics engineer who has had to scrap more than one printed circuit board over his 30+ year career, I'm a bit jealous at how _relatively_ easy it is for you to correct your mistakes. Kudos for sharing them with us!
Not every mistake has a tidy recovery, some tiny bonehead moves can ruin days of work and some very expensive material. Some of these metal products have a hefty price tag from a supplier dont forget. I'm sure you can relate after hours of meticulous soldering only to have a slight lapse or faulty component ruin your hard work :). That was a very good recovery, I'm really glad it worked out.
The end product is very nice and you did very well to stick with it and not scrap this part & go for a new one. Working through the problems with nice solid solutions is where it's at. Kudo's to you and the wife for the sleeve idea. Sleeving is something that we do a lot of at work to repair shafts with corrosion damage and also other parts. Not always possible but work well when they do. I would have given the Chuck more time to heat up and expand and at least a good 4hrs in the freezer for the sleeve. A little trick that I've learned is to set your telescope gauge to the size of your sleeve plus a few thou. Heat up the hole, let it expand and when the telescope gauge goes into the hole then your sleeve will fit nicely. Still need a gentle tap. Plus on your sleeve, make a small 60°chamfer so that it sleeve centres nicely in the hole.
Amazing job! Keep posting more videos. Reminds me of my father. He was one of the best tool and die makers out there (RIP). I use to see him do complicated setups like this all the time as a kid. Now I am an engineer thanks to him. Thank you!
@@InheritanceMachining Awesome! Keep up the good work! Your grandfather and my dad are a dying breed. Thisb s a dying trade you know. Everyone does CNC now but can't do manual machining id their life depended on it.
That turned out fantastic. I'm a gunsmith that started out as a machinist, taught by my father a tool and die maker. Whenever I'm unfortunate enough to have to sleeve something I turn the sleeve OD to the hole ID and then lightly knurl .002 onto the sleeve, epoxy and press into place then clean up. Your repair was perfect.
18:49 At least your 'special' CB will live under the chuck, so you will only be reminded if changing out the chuck. I cried out with the quill handle snap. When you found out the one 0.875" hole was actually 1-1/2" 🙂, I immediately was 'brass plug bored out proper' so on the same page as your wife, but I am kind of glad you went steel and it came out beauty, and the co-boring ALL the holes to 0.9 was a good idea. I was a bit worried with the plug after the heat equalized that it may not budge, but glad the 'persuasion' sorted it to full depth. Proud subscriber, waiting for the next installment.
Glad you enjoyed it and thanks for all the support! It means a lot. Also on the shrink fit I really didn't heat it that much to begin since there was so much mass there, especially with the table.
This is my new favourite machining channel. Absolutely love the slow pacing, the subtle humour and the awesome results your machining produces. I'm mainly watching it for entertainment purpose since I'm not a machinist myself. I'm more of a hobbyist woodworker. But you wouldn't believe how much tips and tricks a woodworker can get from a good machinist. Everything from measuring to work holding is a infinite number of steps up from what's actually needed for most woodworkers. Me however, I strive for a precision on my woodworking projects that almost(well...quite far from almost, but hey...) is on par with machining. Thank you so much for this channel!
Thanks so much! I do a bit of woodwork myself and I'd say there are a lot of overlaps. Wood also has its own special challenges being non-homogenous and more susceptible to temperature and humidity. From that perspective I wouldn't claim that metal machining is any more advanced. Anyway thanks again for the support!
Brandon, I have to say big thanks for your videos. I have no idea why me as web developer have this sick interest to videos of machining. You channel is awesome. Your videos are awesome. I getting huge doses of dopamine watching you videos. Just a few days I got your channel in recommendations and I'm so happy because of it. Only few videos left to watch and I'll be waiting for new videos much more stronger then for all of series I've watched. The biggest appreciations for you and your wife for this story. With you both I have this chance to watch this awesome story of inheritance. I have a chance to improve my english as well. I have a chance to listen to good music. Big thanks right from my heart
My Dad always said “did ya learn your lesson?” I said yes. He said “ok , call it a learning process” Ain’t a day goes by I wish Dad was still here. Praise The Lord for a memory ❤️👍
I'm so happy you inherited those machines - TH-cam is a much much better place because of it! You've managed to hit your own style and beat in a sea of machinists on here, and it's so very enjoyable to watch and listen to!
Breaking the quill lever was almost the first thing I did when I started a new job at a machine shop last April. I have a sneaky feeling they get fatigued too much because of a lacking relief cut. New one I made has been working fine, and to make sure it would hold for a while since I made it out of a beefy threaded rod made of A4 steel. (larger diameter than the threads needed, cut of the threads in the lathe (almost all the way, so you still had a shallow thread going the whole way, looks nice) and threaded the two ends)
So many good lessons here for the rest of us. Thanks for sharing as we all need frequent reminders. It's amazing how many silly mistakes one can make in such a short time span as soon as one bad thing happens. Make one mistake and then you overcorrect and overcorrect and never stop to think.
Brandon. i just wanted to take a second to let you know ive been having a hell of a couple days at odds and out of sorts. feeling a lil ill to top it all off... going back through your catalog and watching a couple of episodes really did help relax me man. much appreciated.
This turned out great despite your mistakes, Brandon! Thank you for sharing this with us. I'm excited to see the finished adapter and how it works! Keep up the great work.
Neat video. Wow, I haven't seen a drafting machine like that since I was an Engineering undergrad in the late 1960s. I used one that my older brother had, he moved from the machine to a simple parallel bar. When his engineering company hired me an an intern during college, I grew to prefer the parallel bar as well. (sometimes nepotism is very nice).
Great video. Great recovery. End results priceless. I bought the drawings from the ASME to duplicate a similar build for a D1-4. All I can do is hope it comes out close enough to do the job. Having the tools to work with means everything to a Hobbyist. We kind of learn as we go at times when it get complicated. My mill will be a JET 2hp mill/drill. It doesn't belong to me and sits at a friends shop about an hour away. IF we can get past the setup and take baby steps it might work out fine, of course nothing like you did. But we did pick up some good ideas watching your build. Thanks.
I'm really enjoying your videos. I know exactly what it's like to have one bad decision snowball into a series of them. It's good to see how different people go about solving screwups.
I'm so glad you leave in the mistakes. We all make them. But I'm amazed at how you fixed your mistakes. The bush was a great idea. Very well done, you can be proud of yourself. Cheers. Looking forward to the next video.
Your voice-overs are so calm and relaxed that I _really_ appreciated the break into real-time audio when you, ah, gorilla'd the quill handle off :) My workshop air is usually filled with blue words..
i appreciate that you have the full documentation of your journey its helpful i often find myself saying to myself" i could just do X" or " i dont know why i couldnt do x to make it easier" nice to both know im not theonly one that finds myself doing that and also why "x" isnt gonna be faster but sometimes its fixable lol look forward to watching more of your stuff
Astonishing job! Never characterize a mistake as stupidity. Stupidity is a result of an intentional error, not an accidental error. Keep up the good work!
😳 Snuck in a part 2!! Good stuff as always Brandon. As echoed by a lot of other commenters, love how you are so unafraid to share your mistakes and how you went about fixing them.
2 for 2! 😂 Thanks man. I'll continue to share them when they happen. As long as people can learn from them then I think they are valuable to show. And if not, at least they are entertaining
The Machinist's Mental Toolbox is even more important than the Kennedy box (at least I think it is). When you blow a setup or muff a procedure it gives you a chance to work on the mental toolbox. And that makes for faster recoveries in the future. Good looking part.
Hi Brandon. Fascinating. Leaving out practicality I've frequently wondered what it would take to convert my lathe spindle to a 'D' series. The practical aspect being the additional overhang of course. The real answer folks is a new spindle - or lathe but neither of those is going to happen. Still, very useful to see what is involved. Thanks.
For times when you can't heat one part enough, liquid nitrogen can shrink a bushing a bunch. Then the parts go together with no drama. You can get some at many welding supply places.
Hi mate, you are so thorough and brilliant at showing yourself dialing everything in on the machines, visually and verbally painting a fantastic picture of all your operations. I feel I've learnt a bunch! From the drawing to this, it's awesome. Thank you for taking the time to do this. All the best
You had us wondering if you had a boring head until it showed up. Not going to razz or jeer as we've all taken shortcuts and learned not to from traveling down that road. The quill press through; that was an OH NO moment. Congratulations on salvaging the adapter and keep making your grandfather proud. Cheers!
This is the best series that teaches more than just machining. What do you think about putting all your mistakes in a playlist and titling it “Defect Driven Continuous Improvement”?
That was a very complex project, great job! Love you post from all aspects, machining, video and narrative. This was even "action packed". I remember yelling inside "Nooooooo! when you tried to use the quill as an arbor press :)
When you tried using your part off tool on that large diameter, lower your RPM and feed faster. It will stop the chatter. Make sure you always use oil on your part off tool and watch your chips. If your chips are small or it starts to chatter, feed faster.
Really enjoyed this episode. As my hero Albert Einstein once said "Those who don't make mistakes are the ones who don't do anything". BTW the quill handle you broke can be replaced by after market wheel if you like.👍
It's nice to know it's not just me that starts with a plan, which goes wrong, and then I spend 3x as much time and/or money coming up with creative solutions to my ineptitude.
That is an amazingly complex project and making a mistake is almost unavoidable. Your channel is unique and we highly appreciate it. Thanks for all of your efforts to share your work with us, boo boos and all.
Oh- Oh dear that uh, got out of control quickly. lol Damn good recovery though. I'd've considered scrapping it. My first thought was building the hole back up with tig weld, but, that uh, probably wouldve just made things worse. Sleveing it was def the right move though an actual arbor press might be in order. Actually, if you havent got one, that sounds like a good idea for a future project.
Nice project. I'm currently making an adapter for my lathe to convert it from threaded spindle to D1-4. I was also going to drill the cam holes to size but I'll use my boring head now. Looking forward to seeing next video.
Thanks and glad this popped up in time for you. I actually got a recommendation to bore to within a couple thou then ream the rest for a better finish. The ream I did turned out bad only because I was taking close to 70 thou
Try using an end mill with less flutes to stop it from bouncing. 2 or 3 flute end mills are perfect for these types of applications, especially drilling into part of a cross hole, you were right about that, but four flutes doesn't allow enough room for chip evacuation. Not a criticism, just some friendly advice. Love your channel man.
Good lesson in recovering (wives are so supportive when we are down in the dumps, hopefully!) and great suggestion with the sleeve .. My wife always says if ya cant hide it feature it (quite a brilliant artists chick) Cheers and a great job i would have never tackled. (love that it's your granddad's shop you inherited by the way, great way to celebrate their life by continuing on) and i bet grandpa could tell a million stories of success and failure.
What would we do without our better halves? Also continuing what my grandfather started is a big reason for my drive to do all that. Thanks for the support!
That sleeve looks 👌 Also, first time I've ever heard a machinist actually talk about taking the heat of the part into consideration for the final measurements. Of course it's obvious now that you say it but I've never thought about it before. Very cool
I do machine work in a food plant maintenance dept. 99% of the work is 303 or 304 stainless. Both have a thermal coefficient about twice that of carbon steel. Consequently, I routinely take the temperature of parts into account on close fitting parts.
I have to credit my wife again for not only the project saving idea, but also for all her support with the channel. These videos wouldn't be possible without her.
Join us again on Friday September 16th at 10am EST for what will hopefully be the conclusion to this project. Fingers crossed for no more mistakes. Or at least no more BIG ones.

@@BrilliantDesignOnline, Paige’s channel is called Farmhouse Vernacular.
I know exactly what you mean about our Better Halves.
Haha, my wife puts up with the mess I make and the expensive hobby. The better halves definitely deserve a lot of credit 😆
As a fellow toolmaker and engineer, I think it's great that you don't leave out the mistakes. Anyone watching can learn from that. The adapter looks great.
Thanks. That's exactly why I leave them in.
When we are talking about misstakes, there are 2 different people. The ones who hide it, and the ones who are talking to colleagues about best way to fix it. I have seen both at my work. Everyone makes a misstake sometime.
Yes, 100%. That’s the place where I learn new techniques and approaches. Keep including them!
mistakes are how i learn myself, you learn explicitly WHY you shouldnt cut corners
The box of shame had a fine feast.
beautiful
Thank you, sir!
There's nothing more gut wrenching than screwing a part, and nothing more satisfying than the bodgery required to salvage it actually coming out looking professional.

16:59 I like to think of this as "Clickspring clean" as far as sanding away a metal join until it becomes invisible goes. Well done and nice recovery!
A little sand paper will go a long way... Thanks!
ah, i see you are a man of culture as well...🤣🤣🤣🤣
Clickspring is out of this world clean

I give you a tremendous amount of respect for showing your mistakes along with everything that went right in your videos . We learn so much more from our mistakes than we do from our successful endeavors .
As an electronics engineer who has had to scrap more than one printed circuit board over his 30+ year career, I'm a bit jealous at how _relatively_ easy it is for you to correct your mistakes.
Kudos for sharing them with us!
It only looks easy on film 😂 My pleasure!
Not every mistake has a tidy recovery, some tiny bonehead moves can ruin days of work and some very expensive material. Some of these metal products have a hefty price tag from a supplier dont forget. I'm sure you can relate after hours of meticulous soldering only to have a slight lapse or faulty component ruin your hard work :).
That was a very good recovery, I'm really glad it worked out.
The end product is very nice and you did very well to stick with it and not scrap this part & go for a new one. Working through the problems with nice solid solutions is where it's at. Kudo's to you and the wife for the sleeve idea.
Sleeving is something that we do a lot of at work to repair shafts with corrosion damage and also other parts. Not always possible but work well when they do. I would have given the Chuck more time to heat up and expand and at least a good 4hrs in the freezer for the sleeve. A little trick that I've learned is to set your telescope gauge to the size of your sleeve plus a few thou. Heat up the hole, let it expand and when the telescope gauge goes into the hole then your sleeve will fit nicely. Still need a gentle tap. Plus on your sleeve, make a small 60°chamfer so that it sleeve centres nicely in the hole.
Thanks, man. Also very clever idea with the bore gauge. I'll be remembering that one!
Amazing job! Keep posting more videos. Reminds me of my father. He was one of the best tool and die makers out there (RIP). I use to see him do complicated setups like this all the time as a kid. Now I am an engineer thanks to him. Thank you!
Thank you very much and sorry for your loss. My grandfather had the same effect as I'm now an engineer as well
@@InheritanceMachining Awesome! Keep up the good work! Your grandfather and my dad are a dying breed. Thisb s a dying trade you know. Everyone does CNC now but can't do manual machining id their life depended on it.
That turned out fantastic. I'm a gunsmith that started out as a machinist, taught by my father a tool and die maker. Whenever I'm unfortunate enough to have to sleeve something I turn the sleeve OD to the hole ID and then lightly knurl .002 onto the sleeve, epoxy and press into place then clean up. Your repair was perfect.
Thank a lot! That's also an interesting strategy that probably has its merits. I'll remember that one
18:49 At least your 'special' CB will live under the chuck, so you will only be reminded if changing out the chuck. I cried out with the quill handle snap. When you found out the one 0.875" hole was actually 1-1/2" 🙂, I immediately was 'brass plug bored out proper' so on the same page as your wife, but I am kind of glad you went steel and it came out beauty, and the co-boring ALL the holes to 0.9 was a good idea. I was a bit worried with the plug after the heat equalized that it may not budge, but glad the 'persuasion' sorted it to full depth. Proud subscriber, waiting for the next installment.
Glad you enjoyed it and thanks for all the support! It means a lot. Also on the shrink fit I really didn't heat it that much to begin since there was so much mass there, especially with the table.
This is my new favourite machining channel. Absolutely love the slow pacing, the subtle humour and the awesome results your machining produces. I'm mainly watching it for entertainment purpose since I'm not a machinist myself. I'm more of a hobbyist woodworker. But you wouldn't believe how much tips and tricks a woodworker can get from a good machinist. Everything from measuring to work holding is a infinite number of steps up from what's actually needed for most woodworkers. Me however, I strive for a precision on my woodworking projects that almost(well...quite far from almost, but hey...) is on par with machining. Thank you so much for this channel!
Thanks so much! I do a bit of woodwork myself and I'd say there are a lot of overlaps. Wood also has its own special challenges being non-homogenous and more susceptible to temperature and humidity. From that perspective I wouldn't claim that metal machining is any more advanced. Anyway thanks again for the support!
Brandon, I have to say big thanks for your videos. I have no idea why me as web developer have this sick interest to videos of machining. You channel is awesome. Your videos are awesome. I getting huge doses of dopamine watching you videos. Just a few days I got your channel in recommendations and I'm so happy because of it. Only few videos left to watch and I'll be waiting for new videos much more stronger then for all of series I've watched. The biggest appreciations for you and your wife for this story. With you both I have this chance to watch this awesome story of inheritance. I have a chance to improve my english as well. I have a chance to listen to good music. Big thanks right from my heart
My Dad always said “did ya learn your lesson?” I said yes. He said “ok , call it a learning process” Ain’t a day goes by I wish Dad was still here. Praise The Lord for a memory ❤️👍
I'm so happy you inherited those machines - TH-cam is a much much better place because of it!
You've managed to hit your own style and beat in a sea of machinists on here, and it's so very enjoyable to watch and listen to!
Thank you so much!
Breaking the quill lever was almost the first thing I did when I started a new job at a machine shop last April. I have a sneaky feeling they get fatigued too much because of a lacking relief cut. New one I made has been working fine, and to make sure it would hold for a while since I made it out of a beefy threaded rod made of A4 steel. (larger diameter than the threads needed, cut of the threads in the lathe (almost all the way, so you still had a shallow thread going the whole way, looks nice) and threaded the two ends)
That recovery was top. Man who never made a mistake never made anything.
what a great tip to repair an oversized / damaged hole with a sleeve. sometimes you need to see something to get enlightened
I'm the same way. Glad I could help!
One learns more from mistakes than from successes, thanks for another very nice video.
very true. Thanks!
So many good lessons here for the rest of us. Thanks for sharing as we all need frequent reminders. It's amazing how many silly mistakes one can make in such a short time span as soon as one bad thing happens. Make one mistake and then you overcorrect and overcorrect and never stop to think.
That really sums it up nicely Happy to share for exactly that reason. I need the reminders myself honestly (and obviously)
Brandon.
i just wanted to take a second to let you know ive been having a hell of a couple days at odds and out of sorts. feeling a lil ill to top it all off...
going back through your catalog and watching a couple of episodes really did help relax me man. much appreciated.
Shoot, man. Sorry to hear that. I appreciate that my videos could help though. Hope you feel better soon
It's not how many times you do things right,,, it's how well you are able to recover from mistakes.
Great lesson for when things don't go as planned. I think fixing mistakes take more skill than when things go smoothly. Well done. Thanks for sharing.
If not more skillful at least you might learn a new technique or two. Thanks!
This turned out great despite your mistakes, Brandon! Thank you for sharing this with us. I'm excited to see the finished adapter and how it works! Keep up the great work.
Thanks, Jay! You and I both!
Neat video. Wow, I haven't seen a drafting machine like that since I was an Engineering undergrad in the late 1960s. I used one that my older brother had, he moved from the machine to a simple parallel bar. When his engineering company hired me an an intern during college, I grew to prefer the parallel bar as well. (sometimes nepotism is very nice).
Great video. Great recovery. End results priceless. I bought the drawings from the ASME to duplicate a similar build for a D1-4. All I can do is hope it comes out close enough to do the job. Having the tools to work with means everything to a Hobbyist. We kind of learn as we go at times when it get complicated. My mill will be a JET 2hp mill/drill. It doesn't belong to me and sits at a friends shop about an hour away. IF we can get past the setup and take baby steps it might work out fine, of course nothing like you did. But we did pick up some good ideas watching your build. Thanks.
When we insert new valve guides we oven the cylinder to 300, freeze the guide then coat the guide in Crisco.
ponder about life and the universe, well spoken
that sleeve was a good fix . all in all looks pretty good
Thanks! Turned out better than I expected
Thanks for including your mistakes. Mistakes are how we learn. Every mistake is invaluable.
Without mistakes, we'd never learn problem solving. Plus it's cool to see the solution.
I'm really enjoying your videos. I know exactly what it's like to have one bad decision snowball into a series of them. It's good to see how different people go about solving screwups.
I'm just glad I'm not the only one. Though I suspected I wasn't 😉 Thanks for watching!
I'm so glad you leave in the mistakes. We all make them. But I'm amazed at how you fixed your mistakes. The bush was a great idea. Very well done, you can be proud of yourself.
Cheers. Looking forward to the next video.
Thank you very much!
Your voice-overs are so calm and relaxed that I _really_ appreciated the break into real-time audio when you, ah, gorilla'd the quill handle off :) My workshop air is usually filled with blue words..
Thanks! Most of my real time audio is curse words as well 😂 especially when I do something stupid
i appreciate that you have the full documentation of your journey its helpful i often find myself saying to myself" i could just do X" or " i dont know why i couldnt do x to make it easier" nice to both know im not theonly one that finds myself doing that and also why "x" isnt gonna be faster but sometimes its fixable lol look forward to watching more of your stuff
Envy having an engineering supportive wife..
Though, that hand drawing is a channel by itself!
Would love to see more!
Thanks! No doubt I'll be dabbling in it more
Astonishing job! Never characterize a mistake as stupidity. Stupidity is a result of an intentional error, not an accidental error. Keep up the good work!
I suppose you're right... Thanks!
😳
Snuck in a part 2!!
Good stuff as always Brandon. As echoed by a lot of other commenters, love how you are so unafraid to share your mistakes and how you went about fixing them.
2 for 2! 😂
Thanks man. I'll continue to share them when they happen. As long as people can learn from them then I think they are valuable to show. And if not, at least they are entertaining
Well done on that piece what makes the engineer is knowing how to fix it when it goes wrong
That's very kind. Thank you!
Excellent recovery! I had that heart sinking moment just as though it was my own project. Glad you got things back on track 👍
I think we've all been there. Thanks man!
The Machinist's Mental Toolbox is even more important than the Kennedy box (at least I think it is). When you blow a setup or muff a procedure it gives you a chance to work on the mental toolbox. And that makes for faster recoveries in the future. Good looking part.
Very good point! Thanks
Hi Brandon. Fascinating. Leaving out practicality I've frequently wondered what it would take to convert my lathe spindle to a 'D' series. The practical aspect being the additional overhang of course. The real answer folks is a new spindle - or lathe but neither of those is going to happen. Still, very useful to see what is involved. Thanks.
I like your sense of self humor.great job
For times when you can't heat one part enough, liquid nitrogen can shrink a bushing a bunch. Then the parts go together with no drama. You can get some at many welding supply places.
Hi mate, you are so thorough and brilliant at showing yourself dialing everything in on the machines, visually and verbally painting a fantastic picture of all your operations. I feel I've learnt a bunch! From the drawing to this, it's awesome. Thank you for taking the time to do this. All the best
Much appreciated. Thank you!
I've made a few adaptors for the same taper. I believe that crazy angle is also 1 in 8. Much simpler to set...
You had us wondering if you had a boring head until it showed up. Not going to razz or jeer as we've all taken shortcuts and learned not to from traveling down that road. The quill press through; that was an OH NO moment. Congratulations on salvaging the adapter and keep making your grandfather proud. Cheers!
Thanks! Yeah for some reason I thought I wouldn't have had the clearance so didn't even think to use it until it was my only option.
You explain the entire process so clearly. This is becoming more of a favorite channel.
I love to hear that. Thank you so much!
This is the best series that teaches more than just machining. What do you think about putting all your mistakes in a playlist and titling it “Defect Driven Continuous Improvement”?
That's not a bad idea! You got my wife onboard so that says a lot 😁 Thanks for the support!
That was a very complex project, great job! Love you post from all aspects, machining, video and narrative. This was even "action packed". I remember yelling inside "Nooooooo! when you tried to use the quill as an arbor press :)
Thanks, Jose! Yeah haste usually leads to bad decisions. Fortunately everything seems to be alright (except the poor handle).
@@InheritanceMachining How ‘bout that rotary table? Did the hammer thwacking do any damage? 🤔
@@wayngoodman3099 From what I can tell so far no. I think it's mass saved me!
I made a similar fixture for my d1-4 but with a mounting flange to mount flat on the mill table and a 1-1/8 12tpi thread for the dividing head.
Nice!
The best machining channel on TH-cam in my honest opinion! Well done Brandon, you do gramps proud buddy! /Cheer
Without mistakes, there is nothing to learn. Good rescue operation on the hole, thumbs up.
Very true. Thanks!
When you tried using your part off tool on that large diameter, lower your RPM and feed faster. It will stop the chatter. Make sure you always use oil on your part off tool and watch your chips. If your chips are small or it starts to chatter, feed faster.
Really enjoyed this episode. As my hero Albert Einstein once said "Those who don't make mistakes are the ones who don't do anything". BTW the quill handle you broke can be replaced by after market wheel if you like.👍
Thanks and very true quote! I've seen those wheels but not sure would like it
It's nice to know it's not just me that starts with a plan, which goes wrong, and then I spend 3x as much time and/or money coming up with creative solutions to my ineptitude.
Comforting for me as well lol
Sleeve for the win!! Excellent solution. This project looks like a ton of fun to envision, plan, and, execute.
Woot Woot! Thanks. it definitely was!
listened with headphones for the first time. your intro music slaps in stereo
😎
That is an amazingly complex project and making a mistake is almost unavoidable. Your channel is unique and we highly appreciate it. Thanks for all of your efforts to share your work with us, boo boos and all.
Thanks as always, Bruce! Happy to share all aspects of shop doings
beautiful part and wonderful recovery.
I had no idea machining could be this intense!
Oh- Oh dear that uh, got out of control quickly. lol Damn good recovery though. I'd've considered scrapping it. My first thought was building the hole back up with tig weld, but, that uh, probably wouldve just made things worse. Sleveing it was def the right move though an actual arbor press might be in order. Actually, if you havent got one, that sounds like a good idea for a future project.
Thanks! I know right... 😂 I actually have a hydraulic press that would have worked perfectly but didn't want to have to break down my setup.
Don’t you just love the look of machined parts. Thanks for sharing this awesome project 👍🏻
I do! My pleasure
Nice project. I'm currently making an adapter for my lathe to convert it from threaded spindle to D1-4. I was also going to drill the cam holes to size but I'll use my boring head now. Looking forward to seeing next video.
Thanks and glad this popped up in time for you. I actually got a recommendation to bore to within a couple thou then ream the rest for a better finish. The ream I did turned out bad only because I was taking close to 70 thou
Very nice work! You and your grandchildren should be very proud.
I hope they will be. But that's also a long ways down the road!
Try using an end mill with less flutes to stop it from bouncing. 2 or 3 flute end mills are perfect for these types of applications, especially drilling into part of a cross hole, you were right about that, but four flutes doesn't allow enough room for chip evacuation. Not a criticism, just some friendly advice. Love your channel man.
Ah ok. That's great advice! Thanks!
I love the work! Very inspiring to me. I would have blown a fuse at the quill lever snaping. Good job pushing through to the end, it looks marvelous.
Thanks a bunch! Oh I did blow a fuse but decided to cut out the rest of that clip 😂
Good lesson in recovering (wives are so supportive when we are down in the dumps, hopefully!) and great suggestion with the sleeve .. My wife always says if ya cant hide it feature it (quite a brilliant artists chick) Cheers and a great job i would have never tackled. (love that it's your granddad's shop you inherited by the way, great way to celebrate their life by continuing on) and i bet grandpa could tell a million stories of success and failure.
What would we do without our better halves? Also continuing what my grandfather started is a big reason for my drive to do all that. Thanks for the support!
5 Words! YOU Are A Great Machinist!
I still have a ton to learn but thank you very much nonetheless 😁
That sleeve looks 👌
Also, first time I've ever heard a machinist actually talk about taking the heat of the part into consideration for the final measurements. Of course it's obvious now that you say it but I've never thought about it before. Very cool
Thanks man! Yeah I usually go by feel. If it's too hot to touch its probably too hot for a good measurements. At least in the ten thousandths range
I do machine work in a food plant maintenance dept. 99% of the work is 303 or 304 stainless. Both have a thermal coefficient about twice that of carbon steel. Consequently, I routinely take the temperature of parts into account on close fitting parts.
very good complicated job..thanks for your time
thank you and thanks for watching!
Very, very nice video. Nice to see how you repair your mistake.
thanks!
I have watched this viedo multiple times by now and the "Death"-joke gets me every single time.
You do know how to pull it through - well done
😎 Thanks!
Your channel is better than netflix. I m kind off Binge watching all the videos reached here for now. Amazing content brother. Keep them coming.
I really appreciate that man! Thank you
Que sorte a minha de encontrar um canal assim tão rico de boas informações, satisfação em vê-lo trabalhar
