After about two years I've finally finished and made my first parts yesterday. I just wanted to post some pictures and give a BIG Thank you to all those who have helped me and responded to my posts. Also a BIG thank you to all of you who have put in countless hours writing and building Linux CNC. You have truly done the heavy lifting here. I just connected stuff together, and did a whole lot of reading.
Thank you all!

Build List.

Is that a motorised compound slide? I don't think I have seen that done before.

No, but it has a rotary encoder inside. It's not hooked up, but I left in there in case I every thought of a use for it.
The whole machine is kind of strange. It was only a single axis CNC and you switched between x and z with a gear lever.
Tapers had to be cut old school, and it had a special tool holder that just actuated in and out for threading.

OK, in that case I guess it makes some sense. But not much.
On the two lathes that I have converted to CNC I have removed the compound completely.

Those special Multifix threading holders are actually quite sought-after. if it is one of these

Possibly worth keeping, though, as the tangential tool is rather nice and easy to resharpen. Unlike insert tooling.

Attached a picture it just takes standard stick tooling. The solenoid moved it back and forth about a quarter inch.
I'd be willing to sell it, or barter for some other multifix holders if anyone is interested.

I think that it is the manual ones that people want.

I bought a bunch of holders from: www.createtool.com/ They are in China but reply very promptly to emails and are very helpful. They don't advertise them, but they sell blank toolholders too (the block with the spline and adjuster, but no slots or holes). I used one of those to make a holder for a P H Horn RNK224 parting tool cartridge.

I watched a guy use a manual one on youtube, he still had both hands busy to make a thread. Personally I'd rather hit the green button then stand back and drink a beer.

Thanks for the link
