oh no...As a machinist, I don't see how this is gonna work out..
Demandred1957 oh dear... you may want to watch this one with your eyes closed Hahahahahah it was a learning experience I can say that for sure
@@JasonWorksAlot Oh god, MY EYES! MY EYES! lol. Good job for not being machinists though. With that said, maybe 50 rpm through weld type material. 1st rule of machining..choke up on it. always have tools/fixtures/etc as stubby/close as you can. Telescoping gauges.. you put them in at a slight angle up and down, snug up the screw, then pivot it down once. withdraw and check. know you didn't ask for advice, but.. since I have been doing it for close to 30 years, just had to give it anyways. Good luck on the next job!
Demandred1957 I very much appreciate it all! I’m not sure if it’s this video or the next one I do mention that we were following the instructions of the owner of this kit, but after a little while it just seemed wrong to me. So Aaron and I started messing around with it some and I looked up the Chinese boring machine I was going to buy for comparison we eventually figured out 100rpm was the fastest we should be turning, our tool stick out was minimal, as the end result was only I think half inch larger than the boring bar’s OD, at the very end we realized that there were pointed cutters as well as face cutters in the kit but we made do. My knowledge of machining is novice at best but I’m trying to teach myself more and more, just never have time. Thanks for taking the time to comment! Have a good weekend
Line boring is not a machinists job, it’s a boily job. Or around here, they just get filipinos in to do it.
@@madaxe79 never heard of such a thing. Must be a stupid union thing. Line boring is a machinist job for sure. If you are cutting metal, it's a machinist job period.
WOW! I will say for your skill level and tooling used not a bad job! Rule of thumb is 1.005 per inch of bore for press fit. I own a line boring company and I only use Climax Portable Machine Tool equipment. Including the bore welder. Basically took you a bit longer but my tooling investment was over $35K. You did it for under $500! Good job guys! Look into CPMT website if you want to "HONE" your skills! Oh, FYI. If you cut it a bit smaller you can home out a few thousandths down to spec. I use a Sunnen hone. Good job! I enjoyed it!
Thank you! I’ll check that out!
So many things to comment on and correct but in the hopes of not having another hr complaint will stick with good job 😜😁
Dirt Perfect oh no Michelle. The floors yours, have at it 😊
Like it when a good plan comes together. Cool how you guys were total strangers a year or so ago and now your all good friends help each other out. TH-cam has brought a bunch of good people together. Stay blessed and work hard
Andy Moss oh I couldn’t have asked for better friends. TH-cam has been wonderful for that. I can honestly say I consider mike one of my closest friends now, can’t say enough good things about him and his family!
Wire wheel it, then setup on machine use crocus clothe fine as possible. A ruff finish can cause metal fragments to stick, getting in-between the bar and bearings causing feed problems, especially if you use oil when cutting. They put a chrome type finish on them because of that. We also make rubber pieces to protect bar and bearings from metal. 3 bearings are always better than 2. Cuts down on wobble.
Looked like fun times. That was a tedious job. I was a press break operator for a short time in a metal fab company and like you I'm a novice at best. It takes years of experience to master machining and Fabricating because everything is very precise. Having said that, you guys done a great job with the tools available to you. Great video and I can't wait to see more. Have a great weekend.
Robert Simpson thanks Robert, yes there’s no replacement for experience in any field but it’s even more so in the field of machining for sure. By the last set we did, we had it down pretty well, not professional but certainly passable lol
I have a homemade line boring setup. It works OK. I've always found it best to bore first, then weld, then bore again. That way you are not boring right through the weld line. I built mine so I can setup the end plates, bore, remove the plates, weld, and bolt the plates back up in more or less the same location. If I can get away with boring and installing a custom bushing I usually go that route.
Couldn’t agree more. I caught some flak for complaining about a setup lended to me for free, and I guess I deserved that but if I’m gonna use fabracobbled equipment I’d like to atleast have a hand in the cobbling of it for reasons like that yaknow? It would have worked much better if we had a rosters welding setup. Of a large enough positioner to put Aaron on and rotate him I suppose... hun designer🤷🏼♂️ thanks for watching along man hope you had a good thanksgiving
Awesome video, can't wait for more.
dwayne morrow thanks! More to come!
This is quite a job you took on so far from home. You seem to be doing a fabulous job.
Thanks for documenting your adventure.
VideosByAl hey that’s what friends are for right?! When ya got good ones, you do what you can to help them out whatever it takes. And I can’t pretend I didn’t enjoy myself the entire time either lol
🤣🤣 so many things I could say. You guys are killing me! Tag team polish l, shaft, ramming in holes oh this is gold 😁
Elite Earthworks LLC you know how I like a good hole to bore out😊😊 hahaha
JasonWorksAlot don’t we all 😁
I've done a good bit of line boring in my time, and thought I had some tough jobs, but never have I ever had to line bore a rough weld. You guys did great for how you had to do it.
One thing that might have helped cut down on chatter, would be having your 'stand off blocks' equally spaced around the original bore. That would have taken a bigger(square) plate to bolt your bearing to, and may have added restriction to the already tough job of welding the bore.
Our set up was also all hydraulic, with variable speed hydraulic motor and a hydraulic cylinder for the feed advance. I had to count RPM's and measure travel with an indicator to figure out my feed rate (and all that would change when the hydraulic oil warmed up). We used a mag drill for set ups, to drill and tap holes in the side of the machines(usually big presses) we were line boring, then bolted our bearing plates to the machine, using spacers to set the bearing back far enough to get the tool in place.
Charles Tucker that sounds like quite the setup! I’d have loved to see it in action! Thanks for the tips!
@@JasonWorksAlot I haven't worked for 12 years and don't have any video of any of the jobs. I just went to look on the website and ended up on the facebook page with no better luck. I do have a picture of the crown of a press we had in the shop, that I line bored, while another guy cut a new crankshaft for it. Maybe I'll ask to see if they might get a clip of an upcoming job one of these days. facebook.com/bosmachine/
Awesome video!!😁👍well today (Sunday) My second attempt to watch this video,Sucessful!😁Anyways Happy Fathers Day to yah😁 Be Safe and God bless!
Dude whats wrong with JB weld 😊. I love the magdrill/ boring bar platform you welded to the main boom 😎 . I see your precision work is a bit to precise hence I landed on this video , there wasnt enough slop for the grease to get in there and Dirt perfect drags you into fix the squeal! Awesome video, I learned something new !
Nice job a couple of good ol boys getting together and gettin er dun
David seaquist doing the best we can with what we got😃
Looked like a fun time good job!
Muddyfeet Concrete Pumping thanks buddy we made the best of it for sure lol. Have a good weekend!
Great video Jason have a great weekend and stay safe 👍
Greg Cothrum thanks Greg you do the same!
You and Dirt Better Than Perfect work very well together. At least it seems so on video.
Looking forward to seeing the follow up video.
Wayne Crews oh were the best of friends now. It’s really great for us. Maybe not so much for Michelle but we’re happy :)
JasonWorksAlot
Maybe that’s the reason for the HR Issue. 🤔
At least the HR Complaint has been dealt with quickly and possibly appropriately.

Man, that's better. Was getting scared that when that boom swung around in the past that the bucket would go flying.
Oby-1 I know! I felt the same way!
nice work. homemade boring setup is on my list of things to make.
73DiamondReo there’s a Chinese one on eBay, 2,990 +900 shipping. I’ll be picking that up ASAP. Comes with the mig attachment and it’s got power feed!
JasonWorksAlot we’ll come on up. I got plenty of iron to practice on.
73DiamondReo don’t you go threatening me with a good time now 😁
Interesting process, I've never done this kind repair but I'm a retired fabricator/machinist and I'm wondering why instead of welding the bore why not bore it for an oversized bushing like a piece of thick-walled DOM tube with a somewhat smaller ID than you need for a pin. The busing and bore could be chamfered on the ends and the busing welded in the bore. then you could just bore the ID of the bushing to the final pin size needed and not have the uneven weld surface to deal with.
So DP's video of this will be up in 4mths. GOT IT! It's like watching the future, bi-monthly. Any newspapers with lottery numbers you can show us. I'm feeling lucky! Lol
Keith L he’s actually running really ahead of schedule so expect to see it in about 10 weeks. 😂😂😂 always check fortune cookies for winning lottery numbers! Duh
Good job guys 👍
MLH Repairs LLC thanks buddy!
Thought they liked the fricken friction. Lol lol
Michael Koop 😉😉
Atta boys. Down and dirty getter done.
Michael J Berg gotta do what’s gotta be done right?! Hope alls well you there my friend
Wow you guys did a amazing job with marginal equipment..a true testament to your talent...I’m wondering how hammered out of round the parent bore was that you found it necessary to do a weld build up......iv seen this done a few times with more specifically designed equipment and I wonder did anyone consider just a oversized bushing and did you use any locking sause to cement the bushing in place as is .001 interference enough?
Charles De Francisco thank you kindly sir! As for over sizing and installing a bushing I’m not sure it would be worth it, we would have lost a lot of the original material on the boss to get the bushing to fit. I want to say this hole was .100 or so out of round. As for the locking sauce, we did not. However green locktite probably wouldn’t have been a bad idea. .003 is what you would usually like to see for the bushing to be oversized atleast in my experience. .001-.003 is the Jonathan Deere spec
Holy cow full speed looked waaayyy too fast! I'm by no means a machinist, but even 100RPM looked fast! Interesting setup. I has lots of questions! But too many to list here! No matter what, if the job got done that's the important part! Still sad to see the end of the floppy bucket. People will speak of the legend of floppy bucket for decades to come.
BurningDinosaurs oh yeah a guy was pretty scared when she spooled up to full giver for sure but we got her good and dialed back. I think by the end we were cutting around 75 ripems give or take. By the way I’ve been binge watching vice grip garage on the youstubes I’m not sure if you’ve come across him yet or not but I’d recommend giving a guy a looksy I think you’ll enjoy
That's interesting 2 C how U boys went about it. We have the same Mag Drill, with an American Machine Tool, boring bar kit. We don't have the auto weld attachment so we over cut the bushing bores then "thick bush em".
Log Dog that’s interesting, you mean you order bushings for holes that didn’t originally have bushings? I was always told to bore it out then weld it, then bore it to size. Glad we didn’t t do it that way woulda been a lot of weld, but it shows there’s a whole bunch of ways to do the same thing
@@JasonWorksAlotHi Jason, I'm not an "Excelent" welder like your buddy, so I bore out the old "Oblong" bushing holes just enough 2 make them round. Then I have the machinist make up a custom "Extra thick" bushing to fit the bore and pin. There is no hole welding required but U cant use OEM bushings.
Log Dog got it! See the holes we bored out weren’t bushing holes to begin with. I think we could have probably bored them big enough to put some bushings in, but I’m wondering how much material would be left in the boss after doing that 🤔 tomato - potato right
@@JasonWorksAlotI C 2, If I have 2 cut a lot out, I usually weld the bushings in. Your way of welding up and cut 2 OEM spec would B the best.One more comment, to line up the bore bar in the oblong holes, the American Machine Tool kit comes with cone shaped plactic spacers that center the bar real good, weld the bearing blocks on, then pull the spacers out, and your ready to bore.
good work! always fun learning as you go. How did you center the bar in the hole?
Travis Macie the owner has a bunch of 1/2” thick washers that are “machined” to a “precise” center and we wrap “precision aligning cloth” (looks a lot like electrical tape but it’s not you can trust me when I say that😉) until we get a snug fit into the existing bore. Kinda crude and I’d have never thought it would have worked so well if I hadn’t seen it myself
@@JasonWorksAlot Nice! i love me some precision alignment cloth!!! In reality, the most important factor is that the hole is round and perpendicular to the boom.....
Michelle? That add in name was hilarious..
Scott Sime yeah, Michelle is a pretty funny guy from time to time. But don’t tell him I said that. It’ll go straight to his head
I don't know much about this process so take this for what it is, but it looked good to me lol.
Sandy hey hey long time no see! How have ya been?!
@@JasonWorksAlot Pretty good, busy as hell dealing with my business, ya know? Businesses get right upset when their confusers go down. Especially with everyone working from home.
Jason what would we rate in Mr. Dirt Perfects eyes, A-TEAM or F-TROOP 😂
Aaron Bumm Man Behind The Scenes oh I’d like to think Michelle would agree were the P-People. Yaknow P for Perfect since were the reason he can keep going out and playing with his youstube doodad all the time. Knows he’s got guys working their tail off for his greater good. It’s real nice of us now that I get to saying it out loud. I think we’re under appreciated.
JasonWorksAlot I would have to agree with you 😂😂😂
Aaron Bumm Man Behind The Scenes you know of anyone we can express these concerns to? Maybe get some change?
JasonWorksAlot well I know the HR lady pretty good 🤣
Aaron Bumm Man Behind The Scenes oh yeah? Does she have a youstube channel too?
when you sanding bars again use a sanding belt band from a sander and a sanding barrel on a cordless drill, turn the band inside out place on work use the drill and barrel sander inside the belt and sand away... faster than doing it by hand... start slwoly and build up speed... it wont slip if done right...
KNIGHTS MEDIA CLUB I like the way you think! Thanks for that
@@JasonWorksAlot there is another way depends if you have the pin with eye bolt fixtures each end, on some of my equipment i drill a hole in each end to fit a headless bolt and use that on the drill and a sheet of sand paper in a half mood block of wood, some of the pins come with eye bolt fixings... or grease nipples i remove the nipple and screw in the bolt and turn it with the drill...
You were a little boring today. LOL😂😂😂
mike seguin hahaha soooo punny hahaha
Great job fellows, for having just the basics. I too will be using a Mag Drill for my first bore job. May I ask you how long the actual job took,all total ? thanks.
If I had to toss out a guess, 12ish hours. Closer to 20 if you count disassembly, reassembly, and welding
Best of luck! Slow rotation and feed will save time in the long run!
I have every confidence that you learned a lot, pity you didn't look at all the cutter at the start you would have seen one that was right for starting with and you were right slow and steady at the start.
barry hansen oh yeah by the end we knew what we were doing. But that’s how it always goes I guess haha. If I were to do it again I’d have cut down one of the shanks of the tools and sharpened it to start the cuts with.
One more comment, with the auto weld attachment, U have to machine the egg hole out to get them round for the auto welder to work, so that's extra maching, where your professional excellent welder can weld up the egg holes, as they are. So, actually he could weld on them before U weld the bearing blocks on 4 better access. Either way U have 2 B Dam good at welding.
Log Dog that’s a solid point you make there. I hadn’t considered it before now. I imagine if it’s not egged too bad you could get away with it but if it came down to it I rather have my buddy do it over the machine so I got someone to talk to while the machines doin it’s thing 😃
Nice job, but are new inserts not available?
Man With A Plan the main boom bosses are machined into the boom, so no bushings. A lot of the pin bosses on this machine are this way actually. Where bushings were used we didn’t bore them out although one of them was on the factory spec we decided to just leave it be.
JasonWorksAlot gotcha
Being a Journeyman machinist for the last 30 years it takes a lot to have a straight and true hole # 1 rigidity #2 correct feed and speed #3 listen to the tool and look at the chip it will tell you all you need to know. By saying all of that boring a welded up hole is never easy.
Lee Cooper it was a challenge for sure. Probably would have been better to have a few “easier” holes done before doing these but hey trial by fire right 🤦🏼♂️
Can believe that this boring video was so interesting. 😁
Wayne Crews and you didn’t even have to wait in line!
JasonWorksAlot
Now you tell me. 🤦♂️
So... in this video we see two dudes built for speed, but tasked with precision, settle in to do a boring task.... And, you are telling me that I’ll have to watch episode 2 to see if the boredom got the best of them!!! did I get that about right?
William Harris id say that was a very precise summary all the way round!
Weld 3 studs around the bearing at roughly 120° apart?
Pretty much yeah. As close to 120 as you can
@@JasonWorksAlot here they are almost in a straight line on the 3/4" plate. That's why I made the remark
Gee guys how did you let that bar go so bad? line borer for years.
All I can say Jason you are a very talented guy, all the best.
Ol 'Nam Grunt thanks for the kind words! I do my best to try and learn new things. Lol sometimes it works. Sometimes it doesn’t. Have a good weekend!
@@JasonWorksAlot ... wrong, because even if it doesn't work out then you learned how not to do it, so that's something new learned too :)
Silent Epsilon never thought of it that way, but it’s a solid point haha!

JasonWorksAlot 😂😂🤷♂️
Mrs Work's alot isn't going to be happy about you putting your shaft into another hole and then you and Aaron tag teaming another shaft. LMFAO 😂 sorry I couldn't resist you left it wide open for me. I'm bored out of my mind living in the hospital. If I didn't have anything to watch TH-cam videos I would have jumped out the window, all the tv channels they have is news, news, news and a few other channels but that's it. Been here 13 days so far and will be here forever unless a Doctor is willing to do surgery on me with a 5 percent of making it thru it without bleeding to death because of the situation I'm in. That's why there has been 67 doctors not willing to operate on me. Congrats on the wedding you have someone special. Hold on tight and never let her go. Ryne
cntsles fabrication she shook her head and Walked away about as much as I thought she would lol. Dude! What the hells going on??
@@JasonWorksAlot 5 year's ago I had to have surgery to remove a ulcer and it took up half of my stomach, so half of my stomach was removed with it and I had zero issues for 7 months. Then I started having issues swallowing food and drink which created even more issues for my digestive system and esophagus so I had to have a procedure 3 days a week to open my esophagus to allow food and drink to get by, but required I needed another surgery to fix my esophagus and my digestive system because it started to fail. I finally found a doctor willing to do that surgery 8 months later after it all started but I lost 90lbs in that 8 months. He had to remove ⅓ on what was left of my stomach and quite a bit of my digestive system. I had zero issues for 2½ years and out of nowhere in March shit hit the fan very quickly. I started throwing up everything I ate or drank and I lost 87 lbs in 90 days and I went saw my doctor and the next morning he did a procedure to see what was going on and my digestive system completely failed and there's nothing any doctor's can do for me and he had me transported to hospital and since I have been here 73 doctor's have come seen me and there's nothing any of them can do because there's nothing left of my stomach left to go through another surgery and if they go in 99 percent chance my digestive system will bleed out and kill me. I'm not giving up at all but there's no surgeon will even try to do anything for me as of right now.
cntsles fabrication holy shit man I’m speechless. Thoughts and prayers for sure I’m wishing you the best
@@JasonWorksAlot thanks Jason I really appreciate it.
cntsles fabrication let us know updates bud. Best of luck and stay strong
Here after dirt perfects warranty claim
Oh man that went live already?! Time flies. Hahaha glad to have you
Honestly it’s the set up.. a tripiod is the rigged set up...most of your issues there ...not in a straight line...a jack support adjustment for the forth leg if needed...carbide cutter can do that small bore at 400 rpm easy. Hi speed tool not so much 200 tops...litl spray lube helps too...cheers...i said to mike in a older video..line bore time. You not getting away with out doing it...haha
knowltek it’s funny you mention the tripod leg arrangement. As I was editing the videos of all this I had a face palm moment and noticed the same thing. I’m not sure why it didn’t dawn on me while we were actually doing it... what a guy would give for a time machine sometimes 😔 thanks for watching along! Next we have to talk him into fixing the 304’s floppy bucket 😊
