Making a Lathe Compound from Scratch

Slideshow and small video clip of the steps I used making a new compound for a collet lathe in class.

so, to make a compound slide, we need something with a compound slide...

[Specsac]

@felderup ,Nope that is called a vise.no compound was used in the making of this compound.lol A blueprint helps but my instructor wanted me to make something new,by copying the old one.

[felderup]

@Specsac thought you made the rotating table for the toolpost mount too, wasn't paying close enough attention.

[Specsac]

@felderup It's cool man,it was a great project and quite challenging at that point in school.Just remember to take measurements off as many places as possible when reverse machining like this. Have fun and thanks for your input.

Hey .... Is that a Revet Lathe?

[Specsac]

@TalksWithDirt ,sorry for the long wait to reply, I believe it's a Hardinge lathe if I remember correctly.

nice work, and alot of chips, maybe it would have been easyer to start with a flat piece instead of a round one ;-)

Would love to have some of those machines here.

Ten pounds of chips wow that could of been used to make 1 2 3 block if you would of just used flat stock.

good job ive done the same

Good reverse engineering. you missed a couple of key steps for the video. like nesting the gibb seat, measuring the dove tail, and some assembly would have been nice. To really do this right you need to case harden the piece and finish grind the bottom or at the very least...lapping to decrease the friction coefficient. You could have made special personalized improvement like oil jackets and a dolimite style oil hole. Good job though.....lots-o-widdling!

No bandsaws in the shop? Save time, material, carbide bits and machine wear. I get it that sometimes there is only one piece of steel to use but the leftovers could be used too instead of turning them into waste. I don't care how great the power and precision of the machinery when the operators do not use the gray matter.

@smalscreen1

I am only guessing you must me a tree lover and a industrial hater? This is what you do when all you have is that peice, a machine is down and you need it up, roundstock will be milled flat or square stock will be turned round. Waste is downtime waiting for parts or stock to make the part you need. Its just steel man, get over it!

 Nice work, saving a machine with a machine :)

@tboost007 4.07 Mins shows the gib strip adjusting.

Nice project especially for a trainee.

Looks like a decent HSS dovetail cutter.

Would hate to put a cost on that job having had to convert a tail stock similar. Many many hours.

[tboost007]

Great video, gave me ideas to make a t-slot compound for my lathe. But i am curious to know, how you lock your compound? I dont see any locking screws on the side.

[MrBeav62]

what rpm do u run those dovetail milling cutters ? was is hss or carbide?

[fjoefourty]

Sort of like how a log could be turned into a toothpick. No table fed band saw in the shop? You know, the receiver of a good Kalashnikov starts out as a fifty pound brick of steel, but that there is just crazy.

[snoopdog68]

that part is worth $1,500. at least,
