As always, Mr Pete has enlightened many of us yet again. Look at the responses below and see how many have already viewed yet another "marvel" by the "master"; and it was put on TH-cam just today. Wow. We luv ya Pete. Keep up the good work. 'Can't wait to see the next video of your Jesus given gift. that will surely dazzle us again! You be "da man" Pete .Bless you dear person.
Thanks for the great video and taking us along. This is a real machinist video and is rare on TH-cam. This is the part of TH-cam I can't believe is free, educational and entertaining can't wait for the next video. Thanks again!!
another great video -- THANK YOU for the very tiny details. they are not boring, they are the rare, priceless gems which refine our thinking. and thanks to those very details over the past few years, you helped us play a vinyl record in near-space for the very first time.
I loved this video. I can't wait for the follow up ones. I'm 50 years old and my son is 12, we love learning together from every one of your videos. Thank You. On a side note: who in their right mind would give this video a thumbs down? Some people in life are just so unhappy.
Mr. Pete, My wife and I recently hosted two friends from Denmark for five days. While in the U.S. they also traveled south all the way to Florida. Being interested in Veteran affair the male guest purchased an impressive commemorative knife. It was quite a large thing for a pocket knife and had US patriotic images inscribed or etched into it. He very proudly presented it to me and stated it was “Made in the USA” which was important to him. As I looked at the knife, admiring the etching, checking it’s sharpness, (it wasn’t) I happened to see that seemingly ever present word in very small capital letters near the base of the blade. I didn’t have the heart to tell him where the knife was made. He is surely going to be disappointed when he discovers it. I strive to avoid making purchases made in that country but it’s becoming ever more difficult. Hopefully the present trade negotiations will alleviate that somewhat but I won’t hold my breath.
Lovely project, also delightful how you compare & contrast models over time & the move to function over form. Very busy myself, but when I do have time I love to look at what you do as it inspires me to try to do things beyond my experience level. Thank you for all you teach!
I liked hearing you talk about the stresses in metal. I was the only one in my shop that seemed to know anything about it. I was constantly frustrated when we would have to make parts that were long enough to bend and would be machined on all sides. They would always order CRS. When I talked about stress, it was like I was talking mumbo jumbo. I finally got them to order HRS for a repeat job we had done before. The results spoke for itself. I'm glad to say my shop is now on the path to understanding stress. In a lot of jobs now, it's standard to stress relieve the material before we even start. Straightening parts and machining bend and twist out of it is so frustrating and time-consuming. I also wanted to mention you were lucky your cut spread apart. I've seen them go the other way and pinch the blade. You would have to drive drifts into the cut to spread the material back out to free up the blade.
I like the newer style "plain" compounds better because you have a flat surface to place dial indicators. My Logan used to drive me crazy because there was no flat surface anywhere for a dial indicator. The "styled" compounds look more elegant, but flat is much more functional. Excellent project! Thank you!
A Fantastic subject and a very practical one, because many lathes are put out of service by compounds crashing into a spinning chuck. This brings to light common issues faced by machinists (not the least of which is the stress in the steel). This also shows how requirements-driven machining rather than machining for aesthetics changes how a part is manufactured. If things don't go to plan, the original compound can still be repaired using fitted steel plates over the old T-Slot with counter sunk/counter bored fasteners holding the plates down.
It's amazing what you can find in a lump of steel, I know all will go well in a craftsman hands, looking forward to the next instalment, happy milling.
I think it would make an interesting project to mill the broken compound and make a new T-slot in addition to making a new top. I really enjoy your presentations.
I bought the Atlas version of this lathe. The compound was broken and I was able to find one on Ebay, it was expensive! However I am not real happy with the design and am seriously considering build one that is a little beefier. Thank you for the video.
Thank you very much Mr. Pete, for all your instructional videos! Thanks to you I just completed making a new compound slide for my Clausing 5914 and it turned out beautifully!
Thrilled to see you making something again! Love the projects. Please show at least some of the setup and machining, too. I do like to see the machines at work in your skilled hands. It doesn't get old and it doesn't circumvent your paid courses, either--on the contrary, it's good continued promotion for them.
Same thing happened to my Father in-law that taught industrial arts at Campion Academy Loveland Colorado, deleted his department for Computer Science and left him without a job. BTW Love the Videos!
I built my replacement compound upper and lower very similarly, but with an exception, I omitted the T-slot and drilled+threaded a single hole for a threaded stud to mount the tool post assembly.
Great video and very interesting. The flat square shape will be a lot better surface to place a dial indicator on than the round stuff you had before. It may have been good looking to the customer but he had not yet tried to mount a magnetic base on it and not have it rock around. Keep on keeping on.
I need to build one myself. It is going to be my lathe's grinding attachment all in one with the compound. So I looked for a Tubalcain video on how to cut a dovetail accurately and ta-dah. The issue here is that I have to wait for the next video because this one was published …guess when? today. Man that's a cliffhanger.
Would that be a Colchester Bantam....I have one too, vintage 1920/30, brought it with me to OZ from UK in 1981. it had that funny block of metal they called a tool post with a slot and a hole in the side and a conical base to adjust the tool height.
Lyle, from the stand point of warping forces, T - Slot first, then Dovetail last to keep it straight. I believe you know this, you're just testing us. Nice vid, Cliff
It would be worth putting that block through a heat cycle to stress relieve it before making a precision slide out of it. And twisting or warping going to manifest itself in a slide with uneven movement. I made one for one of my old lathes on my shaping machine,made a nice job of it and was a delight to use. The dovetail was then hand scraped to get the perfect fit. Have you made a video on hand scraping a way to get optimism fit?
Holly Molly they really had a number on that poor CR. I've seen myself a CR fixed via lobbing off the whole broken tooth?? (not sure how that's named), but in that particular case, the CR was slightly beefier and the repair grafted in to the material with a fish tail cut along the length of the compound rest. I doubt this is possible here, still, i found that repair in particular to be very tasteful and ingenious. Looked pretty too, because of the excellently executed cuts. So there's more than one way to skin the cat. :)
Great project TC , I am going to enjoy this project. I may try my hand at this some day, I have an Asian lathe 12X36 with a tapped hole to mount the tool holder, and would prefer the tee slot design. Now I just have to decide on the option of a new build or a modification.,Cheers!
Interesting project. Looking forward to the rest. I'm thinking I may have to make one specific to mount a tool post grinder I got that will not work to well with the normal compound on my Atlas 10".
Very nicely done. The problem using mild (usually A-36, similar to 12/14) steel against cast iron is that at some point, the steel will tear where they meet. On the other hard, hardened steel against CI make an excellent bearing. A number of old machines do use hardened steel against CI, including for spindles. SPI does make some very good tooling. Remember that Mitutoyo, Starrett and others make tools in China. Really, there’s nothing wrong with Chinese tools.
I do believe that Mr. P. said 12L14. That is leaded steel and machines easily, but it can't be welded and is VERY rust prone. I hope this project ends well. I strongly favor repair, instead of throw away. Eli D.
Would the internal stress be relieved better if maybe .020 stock was left on all sides and the trenches for the dovetail, machine screw and t slot all rough milled out before beginning the finishing steps? It will be interesting to see how the stress affects the finished outside demensions. This is an interesting project. I have a 1930'strong model Sheldon 9" lathe. I am saving to buy a milling machine.
good video brings back memories ...on screw machines the steel plate insert is common..guys putting cheater bar over wrench ....plate holds up well...thanks for video
Mr. Pete, would it serve to braze on cast iron material and machine to shape? Keith Fenner showed how to do that. Heating in wood stove to burn off oils and proceed with brazing while preheated and subsequently slowly cooled under a blanket.
Excellent Mr. Pete! I love all your vids and am a regular subscriber since the beginning, however these kinds of projects are my absolute favorites! Can't wait for the next one! I was surprised just how much stress was in the CRS. Could you heat this in your furnace until red then let it cool slowly to normalize before machining, or would that make much of a difference? Does HRS have the same problem or is that only an issue due to the scale on your cutters?All the best,Bob in Tacoma
Thanks for the Video Lyle. Teacher why was it so important to mill everything to original size? Would it not have been better to have it a little thicker - say 1" and a little wider and longer? I would have thought the only serious sizes would be the Tool Post area and the dovetail. Thanks again Rod
Always enjoy your videos, but man, I was hoping to actually see some of the milling. Maybe you'll share some machine time with us in the remaining segments.
I would do the T-slot first. in case that would cause a slight bow that could change the flatness of the dovetail, if it were already milled. If it were to cup along the length and the t-slot is already there, it's no big deal.
Hi mr Pete that's a good project I made the new compound on my lathe from a price of cast iron I did the dove tail on the shaper . Though then again i don't have a mill as good as you . How will you do the dove tail ?
You can get a 1.5 x 3 x 12 chunk of cast iron from McMaster-Carr. Unfortunately, they want $75 (plus shipping) for it. 1018 the same size would go for about $58.
great video. how do you get oil into that oiler ontop of the compound? I own a QC 42. I got it all back together I need to get a tool post which is my next purchase then I'm off to making chips. thanks for sharing I learn something on every video.
Hi Mr. Pete! When designing the new compound for the Atlas 618, have you found enough clearance to add in anti-backlash nuts for both the compound and carriage/cross-slide? What about screw protectors?
It appears you are not going to stress relieve the CR steel stock. A) Is there some reason for that? You don't want it to warp again after you finish the work. Will the stresses cause it to warp over time? B) Do you feel like doing an experiment using the remainder of the CR stock and seeing how it acts if you make a duplicate part after the stock is stress relieved?
Just for your information.....that the caliper doesn't zero at the top is a common fault with ALL dial calipers no matter who makes them. To get the needle to move to the top you need a narrow piece of brass shim stock about .010" thick, same width as the rack, to slip into the rack and under the small gear then move the slider a bit until it zeros at the top.....takes a couple of goes but it works. A couple of MM off to one side is not a problem. The problem is you just can't keep small dirt out of the rack and this will cause the small gear that meshes with it to hop over the teeth. It's not a design fault it's a fact of life. BTW…..on the desirability stage....I would put a dial caliper second to top of the list over a digital one.....digital ones always have dead batteries when you need them most. Top of the list is the vernier caliper…..they are dead accurate ALWAYS.
Before you started to chew on it take it to a heat treat place and have it normalized NOT stress relieved. Normalizing aligns the stresses not eliminates them. A piece1018/1020 would need to be used as the temperature of normalizing would leach the lead out of 12L14. If you want to use cast iron; you could get a piece of Dura-Bar.
Mr. Pete, I realize the idea is to whittle out a new compound. I think I have an extra compound for the 6" Atlas I would gift to you if you care to have it.
Could any of those stresses cause the peice to twist or warp sometime later from using the part once its finished? And/or could heating it up and letting it cool get rid the stress?
Cold rolled steel and heavy removal normally leads to heavy distortions, probably some stress relief would be in order on a blank slightly larger in order to be able to reset it square after.... To be continued...
Hum... I would heat it more in the 1100 to 1200 deg F for at least one hour up to 2 hours and let it cool in the oven overnight... If not protected from air it will get a scale on the surface, not a problem if you leave more material on the blank, mr. Peterson will have to protect it from air or maybe have to think about another blank... :(
one of my tricks is to put it in the wood burning stove then build a fire keep it going all evening then make certain its buried in the ashes and let the fire burn out and waite tell every thing is cool next day or so normal works good
every time I've done it the metal is glowing so temp is defiantly up there may the next morning its still to hot to hold the coals burning out drops the temp very slowly (old blacksmith trick to normalize.) this is something you can do is a fire pit also very attainable to most people.
I always thought that he did, one of my 'names' is 'Wayland' (as in Wayland's Smithy) another Smith, but a member of the Northern European 'Pantheon' (as against the Greek 'Pantheon').
Hey I need to make one of these too ! Mine is a bit larger though. I have a nice hunk of unknown metal (probably cold rolled) it was cast iron.. thinking about making it and then hardening it ? Or should I not waste the time and order a hunk of cast iron or ductile Iron .. ?
@@mrpete222 I must say, I was not expecting an answer from you, this video is more than 5 years old and still serving the people. I just wanted to say thank you for all the work you put into your videos Pete, I truly enjoy your channel. Hope you keep going strong for many more years!
Love your work, but I would have repaired it in a different manner. I would have done a series of build up welds on the damaged piece. Then, I would have milled the excess down.
Anyone - would it have been worthwhile to anneal the blank before milling to final size to relieve any residual stresses? Or does it not make enough difference to spend the time doing?
Not worth it for this. I'd have left the whole this 0.050" over, but it does not really matter. None of the dimensions of the outside are critical, only the guideway and t-slot are important. All he needs to be able to do is make a final skim over the bottom and top at the end. Rather than anneal, better to just pony up a few bucks for some cast iron. Speedy metals sells 1.25"x2.25" continuous cast for $1.54/inch. Shipping would run more than the metal. Could prolly get a drop off Ebay with free shipping.
That was one nasty "repair" on that compound slide. I wonder if it was even partially usable, or used. I assume you have some corner rounding endmills. I think if I were doing it I'd make a casual attempt to make a likeness of the original shape by rounding the top sides aft of the T slot, and the front corners. Would take more time and make no functional difference, but it would somewhat maintain the look of the machine.
As always, Mr Pete has enlightened many of us yet again. Look at the responses below and see how many have already viewed yet another "marvel" by the "master"; and it was put on TH-cam just today. Wow. We luv ya Pete. Keep up the good work. 'Can't wait to see the next video of your Jesus given gift. that will surely dazzle us again! You be "da man" Pete .Bless you dear person.
Thank you very much-GOD bless you.
"...and the machine shop closed out, and a computer lab installed." I heard the tone in your voice and knew exactly what you thought about that!
Thanks for the great video and taking us along. This is a real machinist video and is rare on TH-cam. This is the part of TH-cam I can't believe is free, educational and entertaining can't wait for the next video. Thanks again!!
another great video -- THANK YOU for the very tiny details. they are not boring, they are the rare, priceless gems which refine our thinking.
and thanks to those very details over the past few years, you helped us play a vinyl record in near-space for the very first time.
Mr Pete, as you can see I'm going back on your older videos, finding them very entertaining and learning a lot, cheers and keep safe
Thanks
Had you been my shop teacher, it would have easily been my favorite class. I so enjoy these videos. On to the next part of this project…
Thank you, glad you like my videos
I loved this video. I can't wait for the follow up ones. I'm 50 years old and my son is 12, we love learning together from every one of your videos. Thank You. On a side note: who in their right mind would give this video a thumbs down? Some people in life are just so unhappy.
YES-there will be many other pokeman imbeciles that will also thumb me down
How miserable is the life of the person who looks for any video to give a thumbs down...
Haters gotta hate
Machining = "releasing parts from their molecular bonds". Love it!
Mr. Pete,
My wife and I recently hosted two friends from Denmark for five days. While in the U.S. they also traveled south all the way to Florida. Being interested in Veteran affair the male guest purchased an impressive commemorative knife. It was quite a large thing for a pocket knife and had US patriotic images inscribed or etched into it. He very proudly presented it to me and stated it was “Made in the USA” which was important to him. As I looked at the knife, admiring the etching, checking it’s sharpness, (it wasn’t) I happened to see that seemingly ever present word in very small capital letters near the base of the blade. I didn’t have the heart to tell him where the knife was made. He is surely going to be disappointed when he discovers it. I strive to avoid making purchases made in that country but it’s becoming ever more difficult. Hopefully the present trade negotiations will alleviate that somewhat but I won’t hold my breath.
You saddened me greatly with that story. But it is so true. All of the commemorative knifes that I have looked at are made in China
When I grow up I hope I'm as knowledgeable and self reliant as you are sir.
Lovely project, also delightful how you compare & contrast models over time & the move to function over form. Very busy myself, but when I do have time I love to look at what you do as it inspires me to try to do things beyond my experience level. Thank you for all you teach!
Can't wait to see the rest of this project! Love it! Thanks for sharing Your wonderful work, Mr.Pete!
I liked hearing you talk about the stresses in metal. I was the only one in my shop that seemed to know anything about it. I was constantly frustrated when we would have to make parts that were long enough to bend and would be machined on all sides. They would always order CRS. When I talked about stress, it was like I was talking mumbo jumbo. I finally got them to order HRS for a repeat job we had done before. The results spoke for itself. I'm glad to say my shop is now on the path to understanding stress. In a lot of jobs now, it's standard to stress relieve the material before we even start.

I've seen them go the other way and pinch the blade. You would have to drive drifts into the cut to spread the material back out to free up the blade.
Spending time to learn about metallurgy goes a long way.
I'll dig it out asap Mr. Pete! You are such a help to us all! It is an honor to pay back - even with such a small thing!
I like the newer style "plain" compounds better because you have a flat surface to place dial indicators. My Logan used to drive me crazy because there was no flat surface anywhere for a dial indicator. The "styled" compounds look more elegant, but flat is much more functional. Excellent project! Thank you!
"This is probably irrelevant. And immaterial. Doesn't matter, either." Hilarious!
This will be a good series. A real life application for those videos you did on machining and measuring dovetails that I watched many years ago.
Looks like a good opportunity for two projects, both a correct repair of the old and a machined from scratch new.
I was going to suggest the same.
A Fantastic subject and a very practical one, because many lathes are put out of service by compounds crashing into a spinning chuck. This brings to light common issues faced by machinists (not the least of which is the stress in the steel). This also shows how requirements-driven machining rather than machining for aesthetics changes how a part is manufactured. If things don't go to plan, the original compound can still be repaired using fitted steel plates over the old T-Slot with counter sunk/counter bored fasteners holding the plates down.
It's amazing what you can find in a lump of steel, I know all will go well in a craftsman hands, looking forward to the next instalment, happy milling.
Irrelevant, In material, and Doesn't matter either.... Greatest quote ever!!!
I think it would make an interesting project to mill the broken compound and make a new T-slot in addition to making a new top. I really enjoy your presentations.
I bought the Atlas version of this lathe. The compound was broken and I was able to find one on Ebay, it was expensive! However I am not real happy with the design and am seriously considering build one that is a little beefier. Thank you for the video.
I love the disdain when you mention "computer lab" replacing the tool shop
lol
Wonderful project Mr. Pete. I can't wait to see part two. Mike
Thank you very much Mr. Pete, for all your instructional videos! Thanks to you I just completed making a new compound slide for my Clausing 5914 and it turned out beautifully!
Great project Mr. Pete. I'll be glued to it. I expect to pick up some tips on repairing an old Palmgren vise as well.
Looks like the making of another great instructional video series.
Thrilled to see you making something again! Love the projects. Please show at least some of the setup and machining, too. I do like to see the machines at work in your skilled hands. It doesn't get old and it doesn't circumvent your paid courses, either--on the contrary, it's good continued promotion for them.
Same thing happened to my Father in-law that taught industrial arts at Campion Academy Loveland Colorado, deleted his department for Computer Science and left him without a job. BTW Love the Videos!
I applaud your compound rest project in steel however your discussion about just repairing the original might have been the best solution. 😆
I need to make a compound for my grizzly mini lathe. I am sure your video will be very helpful for my labors.
I built my replacement compound upper and lower very similarly, but with an exception, I omitted the T-slot and drilled+threaded a single hole for a threaded stud to mount the tool post assembly.
👍👍👍
I'm looking forward to watching this series of videos making the cross slide.
Great video and very interesting. The flat square shape will be a lot better surface to place a dial indicator on than the round stuff you had before. It may have been good looking to the customer but he had not yet tried to mount a magnetic base on it and not have it rock around. Keep on keeping on.
shame to lose the nicely styled part but at least it will be going again .
Can't wait for the corn-clusion of that build.
I need to build one myself. It is going to be my lathe's grinding attachment all in one with the compound. So I looked for a Tubalcain video on how to cut a dovetail accurately and ta-dah. The issue here is that I have to wait for the next video because this one was published …guess when? today. Man that's a cliffhanger.
I am excited to watch this project progress. Always wanted to replace the one on my 1928 Colchester.
Would that be a Colchester Bantam....I have one too, vintage 1920/30, brought it with me to OZ from UK in 1981. it had that funny block of metal they called a tool post with a slot and a hole in the side and a conical base to adjust the tool height.
Lyle, from the stand point of warping forces, T - Slot first, then Dovetail last to keep it straight. I believe you know this, you're just testing us. Nice vid, Cliff
exactly what i was thinking
LoL, but not what was done in next video..
A great demo project. Thanks for tackling it.

I can tell already this is going to be a great series!
Another great project! I prefer to make replacement parts when I can. The compound can be found though, there are 3 on ebay, $20 -$80.....Russ

Thanks again Rod
Enjoy your videos. Hope you don't have much scraping to do on the steel compound.
Nickle rod is for welding cast. Braze is a good alternative as well. I guess neither was in the toolbox of the hammer and chisel mechanic.
Always enjoy your videos, but man, I was hoping to actually see some of the milling. Maybe you'll share some machine time with us in the remaining segments.
I would do the T-slot first. in case that would cause a slight bow that could change the flatness of the dovetail, if it were already milled. If it were to cup along the length and the t-slot is already there, it's no big deal.
Hi mr Pete that's a good project I made the new compound on my lathe from a price of cast iron I did the dove tail on the shaper . Though then again i don't have a mill as good as you . How will you do the dove tail ?
mrpete, I just bought an Atlas 10f and in the box of tooling I found a compound for a 6" which you can have if you'd like it
Love your videos by the way
You can get a 1.5 x 3 x 12 chunk of cast iron from McMaster-Carr. Unfortunately, they want $75 (plus shipping) for it. 1018 the same size would go for about $58.
Great project ! Would normalising the block prevent stress movement ?
Lyle I have a similar job in my future for a 1939 LeBlond ....Thank You mrpete222....Jeff
great video. how do you get oil into that oiler ontop of the compound? I own a QC 42. I got it all back together I need to get a tool post which is my next purchase then I'm off to making chips. thanks for sharing I learn something on every video.
Great video Mr Pete. Ignore the nutters and freaks who thumbs down, they're just wasters.
Great Video, thank you for sharing!
Hi Mr. Pete! When designing the new compound for the Atlas 618, have you found enough clearance to add in anti-backlash nuts for both the compound and carriage/cross-slide? What about screw protectors?

A piece1018/1020 would need to be used as the temperature of normalizing would leach the lead out of 12L14. If you want to use cast iron; you could get a piece of Dura-Bar.
question! the material is cold rolled Steel and may twist and move. would it have to be aneiled at some point, to relax the meterial?
I think you need to cut the T-slot first, otherwise the dovetail might end up crooked from the stress.
Probably you have finished the part by now...
Mr. Pete, I realize the idea is to whittle out a new compound. I think I have an extra compound for the 6" Atlas I would gift to you if you care to have it.
YES-would like it very much--THANKS. Get my mailing address from this video. BACK TO SCHOOL SPECIAL--tubalcain atlas lathe course BRIDGEPORT MILL
WHAT YEAR THAT ATLAS CRAFTSMAN LATHE TUBALCAIN? THAT IS LIVE AND STILL GOOD MACHINE.
Watching with interest. Ultimately, some 'adornment' could be milled in simply if desired.
I would like to weld that compound back up with some nickle rods or TIG it with some Silica Bronze just to see if it would hold up.
Could any of those stresses cause the peice to twist or warp sometime later from using the part once its finished? And/or could heating it up and letting it cool get rid the stress?
You'd probably find the old one too hard to cut where the weld repair was attempted, Might have to grind it down.
why not heat treat the "rough blank" and negate any/all stress? or are you showing us a way around that?
Cold rolled steel and heavy removal normally leads to heavy distortions, probably some stress relief would be in order on a blank slightly larger in order to be able to reset it square after.... To be continued...
Yeah, the barbecue should do it, say an hour at 400 fahrenheit . What do you think Pierre?
Hum... I would heat it more in the 1100 to 1200 deg F for at least one hour up to 2 hours and let it cool in the oven overnight...
If not protected from air it will get a scale on the surface, not a problem if you leave more material on the blank, mr. Peterson will have to protect it from air or maybe have to think about another blank... :(
one of my tricks is to put it in the wood burning stove then build a fire keep it going all evening then make certain its buried in the ashes and let the fire burn out and waite tell every thing is cool next day or so normal works good
Chris Anderson
Good method also as long as the temperature gets around 1200 deg F, needs to cool slowly...
every time I've done it the metal is glowing so temp is defiantly up there may the next morning its still to hot to hold the coals burning out drops the temp very slowly (old blacksmith trick to normalize.) this is something you can do is a fire pit also very attainable to most people.
THANK YOU...for sharing.
I always thought that he did, one of my 'names' is 'Wayland' (as in Wayland's Smithy) another Smith, but a member of the Northern European 'Pantheon' (as against the Greek 'Pantheon').
Thanks for sharing sir....
Can you machine down and bolt in or repair the old one?
I like your videos . When I watch your first video , I subdcribed your channel.
Thanks
Hey I need to make one of these too ! Mine is a bit larger though. I have a nice hunk of unknown metal (probably cold rolled) it was cast iron.. thinking about making it and then hardening it ? Or should I not waste the time and order a hunk of cast iron or ductile Iron .. ?
Just use the steel
@@mrpete222 wow ! Thanks for the reply sir !
@@mrpete222 I must say, I was not expecting an answer from you, this video is more than 5 years old and still serving the people. I just wanted to say thank you for all the work you put into your videos Pete, I truly enjoy your channel. Hope you keep going strong for many more years!
Love your work, but I would have repaired it in a different manner. I would have done a series of build up welds on the damaged piece. Then, I would have milled the excess down.
Anyone - would it have been worthwhile to anneal the blank before milling to final size to relieve any residual stresses? Or does it not make enough difference to spend the time doing?
I have the same question. Would it help to heat the stock and relieve the stresses or is it not possible to do that.
Not worth it for this.
I'd have left the whole this 0.050" over, but it does not really matter.
None of the dimensions of the outside are critical, only the guideway and t-slot are important. All he needs to be able to do is make a final skim over the bottom and top at the end.
Rather than anneal, better to just pony up a few bucks for some cast iron.
Speedy metals sells 1.25"x2.25" continuous cast for $1.54/inch. Shipping would run more than the metal. Could prolly get a drop off Ebay with free shipping.
That was one nasty "repair" on that compound slide. I wonder if it was even partially usable, or used.
I assume you have some corner rounding endmills. I think if I were doing it I'd make a casual attempt to make a likeness of the original shape by rounding the top sides aft of the T slot, and the front corners. Would take more time and make no functional difference, but it would somewhat maintain the look of the machine.
Flat will be better; an upgrade actually. Indicators will stay put.
Yeah he machined it down alright, with a grinder!
