Looking superb, wish I could yhink things through as well as that.

Thanks guys,

Stew, This lathe won't take big tooling as the compound slide is quite high. I doubt it was designed for such as it's really a "second operation lathe" and used a sliding turret.

I tend to use 10mm size same as my mini lathe, but both could take 12mm easily. You could make toolholders for the QCTP to take larger tooling though I would think. I'll prob have a go at some time.

Bernd, yes I know, it might, have to wait and see. If it does I'll just make another in steel. It wasn't hard to make. I just didn't have any steel at the time to make it from.

David, there is nothing difficult here. Even the dovetail could be made on the lathe.
If I were to do it again I'd get a dovetail cutter for the miller. It would be much simpler to keep everything in line. As it is my effort is slightly out. But it works fine.

What I need to do next it adapt it so that the tooling drops on center for both lathes without adjustment. I know how I'm going to do it  :thumbup:


Some more pictures...

Look John, you'll have nightmares tonight  :lol:
I'm using it, first thing I noticed is how true the chuck is. Superb !!!
Second was how noisy it is, I'd forgotten... :ddb:

Altering the size of the piston for a close fit


And here it is in action cutting a piece of steel. I cut the dovetail down tonight to accept the mini's tooling.



Another view, see how much I've adjusted the height setting nut, nip the top off the dovetail will cure it... :dremel:



I'll also make a clamping handle (the top one) so it's better positioned.

Lever forward, released piston



Pull lever back and the pistons fully out. You don't need this much movement, 1/5th of a turn will do to make it nice and tight.



The piston has a good 45 chamfer so that when you drop the tooling in it automagicaly gets pushed back. I guess when I put o-rings on the piston you'll have to push the tooling down.

All in all, it works.... :)

bogstandard:
Very nice job indeed Darren, your bits don't look too bad either :lol:

I was wondering how long it would be before you tried it out, hope it comes up to your expectations.

Darren:
John,

One of the reasons I made this tool holder is so that I can use the mini lathe more...

Don't make sense eh.....sure it does...

It goes like this, I'm doing a bigger, tougher job, need to use the bigger lathe. But the tooling is on the mini lathe, so I rob and get the job done.

Then along comes a little job, be nice to do it on the mini with all it's features. But he tooling is on the bigger lathe. So I think sod it, too much hassle and just use the bigger lathe.

See, makes sense now dunit  :)

To be truthful :dremel: I'm dying to use the mini lathe again, I will think of something to do with it....

Good Job Darren
