Lathe auto-turret project log

[Ken_Shea]

If anybody is interested I could make full drawings of my design. I do have the solid model all done.

Very Generous TY1295,

Put me down

Thanks

That is an impressive project. Nice work so far!

nice work.
Looks very similar in design to Okuma's turret on their "Crown Lathe" models.
good luck with your build.

ps, If your dowel pin idea dosn't work out for you consider a "hirth" style gear set for meshing....just a thought.

How do you plan on mounting the turret onto your lathe? I am trying to figure out the best way to mount this for when I make mine if I do make mine.
I could screw in from the bottom, could put toe clamp slots in the side, bolts from top, could make flanges. I am not sure what the best way to do it is.

I agree the dowel pin isn't best method, but is probably easiest for most to build.

Working on drawings for everybody. Keep in mind I haven't built it yet, just adapted and changed a few things based on my cnc experience.

Yep, I looked at hirth couplings first, but the dowel pin method is far cheaper. We will have to wait and see how strong it will be!
Jon, I figured on bolting it to a steel plate from below, then using the steel plate as a flange to bolt it down onto the lathe. At present, I don't know how much material I will need to remove or add in order to mount it on centre.

[JFettig]

Kong, a suggestion I have is to remove the material from the steel plate rather than the tool turret, it makes for easier transfer to another machine or adjustment.

Thanks Jon, point taken, just as long as I have enough thickness in the steel plate for a secure mounting - ie, no good having a 1/8" mounting plate!
And here is a quick update too - all seals in place, and ready for assembly!

[kong]

And assembled! I expected problems, so I figured on at least one test fit. I have a little binding on the drive plate from the stepper motor to the spindle, so I will have to slot the holes a little. By far the biggest problem I found though, was that the dowels themselves were far too short to reach the spindle drive plate - I never had any longer dowels on hand, so I made a new, thicker drive plate to attatch to the spindle, 0.75" thick as opposed to 0.25" on the original. Now just just gotta sort out that binding, maybe tomorrow

Nice job Kong.

Looking good.

I did get my drawings of the very similar design with just a different face plate for those wanting it.

The real design credit should remain with the original author, I just made a few personal tweaks.

I would love to build one, but my time is limited.

Anybody want to build one for me??

Thanks man, and nice plans too......just a quick comment though, in the left photo in my previous post you will notice a register on the front of the iron block. The mounting plate must go over this to minimize swarf collecting behind the plate. Without it, swarf can get into the groove behind the main spindle and will eventually cause problems. Hope you have time to work this into the plans

Not following you yet.

You saying between the yellow piece and the main housing?
