The mill is CNC?

Yea, I converted it a few years back. I don't actually use it in full CNC mode very much, but most of the time I use it just in manual control mode, sorta like a glorified DRO system.

I did use a Mach3 wizard to cut the pocket for the nut in the tailstock foot.

I got started today by rescuing a piece of very rusty steel (reclaimed from a bent earth spike dug out of the ground and carefully disposed by BT in my back hedge) and lopping off a short section. Then it was a simply a matter of taking very fine cuts (my re-assembled lathe is even more delicate as the old gibs are needing adjusting) to reduce it to 12mm.

Then I spent too long single point threading a 20mm section M12 ( this rare "Scrapbinium" is murdering my Hss threading tools)

Then I cross drilled the other end.

Anyway, on to (slightly) more interesting stuff.

In looking at the tailstock casting, nothing is even close to square.

The area around the hole for the clamping nut is especially bad, I stuck on a 6" rule with a thin magnet to illustrate the angle.

So after deciding that I needed to correct this, I then had to figure out a way of actually correcting it.

After a little thought I remembered that I had a small Angle plate thingy that I've never used up til today. So I dug it out and bolted it on my mill. Then with a little shimming and a couple of toolmakers clamps I ended up with this.

This may not seem very secure, actually it was rock solid. Even so, I took only light cuts, quite a few light cuts as I ended up removing about 1.6mm to get it squared up.

I also took some 8mm steel and offset turned a 12mm section near one end in the 4jaw (sorry no pic, will take one next time of all the componants of the tailstock camlock mod)

Then I got another small bit of 20mm square steel and poked a couple of holes in it.

Then I put all the bits together for a test, gave the sticking out bar of steel a twist with some pliers, and surprise surprise, the tailstock is locked solid.

All that's left to do is to cross drill the sticking out rod of steel (and shorten it) and attach a handle to it. (clear as mud I know, but hopefully it will all come clear in the next update)

The Idea for this kind of tailstock camlock system came from here :- http://warhammer.mcc.virginia.edu/ty/7x10/vault/Members/RickKruger/Tailstock/

Thanks for watching,

Keep it up, buddy, sooner or later I have to do some of this to my lathe (the blue Einhell version)

Hi Tim

You have some very interesting solutions that you have executed on your little lathe.

Well Done, David
