Mini Lathe/Myford Capstan
Joules:
Jonny, your right... But where's the fun in that. I recently made a few dozen nozzles for 3D printers in brass. The idea of a mini capstan lathe appeals to me. I will soon find out what the tailstock turret is capable of, I have a lever operated tailstock on the Myford, but the mini lathe is just standard. I enjoy making tooling so its as much a hobby as practical end use.
Keeps me off the streets. :beer:

I have a couple of the tailstock turrets like the ARC ones but mine are early imperial version for 5/*2 tooling. Had them literally years.
One is set with centre drill, tapping drill and M4 tap, next holes are same again but M6
Second one is for M5 and M8. I split them up this way so you has a viable big difference between taps, easy to get M4 and M5 mixed up when next to each other and you are in a rush.
They work OK but as many have noted it's a lot sticking out and you have to nip the tailstock ram up a bit. Would not try to use them for anything else but they are quick for this job.
I also have a turret for My 14 x 40 TOS lathe that came off a Harrison, needed some work on the base but even so it was miles out on the holes in the turret, so sooner than mess about trying to get it all lined up I got it to fit, then turned the turret down until all the holes had got and shrunk a new top hat on and then drilled and reamed this from the headstock.
I need one for a Generic 14 x 36 and am in two minds to buy the plans for the Grizzly turret advertised and modify that to suit, works out to about £16 in English and that's less than an hours head scratching.

Some time ago I copied the tailstock turret from a mates Schaublin 70. If you're going to copy something, copy the best! It has all the tools parallel to the lathe spindle axis, as a result I'm less likely to leave bits of me on the tools, it's also easier to make!
I only use it for small stuff, under 6mm diameter, mainly model aeroplane needle valve assemblies, as it's fairly small (62mm outside diameter) I used ER11 collet chucks from CTC instead of conventional chucks, they take up less room and allow two chucks to be fitted in adjacent tool positions.
It's a pain to set up, and really it's not very practical for less than a run of 6 or 7. Also it doesn't have the sexy automatic indexing, but it does work fairly well, and for small stuff well worth it.
cheers

Have a look at the Workshop series book ''Mini-lathe Tools and Projects'' by David Fenner. There are detailed descriptions, drawings and photographs for building a tailstock turret for the mini lathe. It looks very professional and with some thought, be modified for use on the cross slide or top slide. The available bed length would severely limit the work you can on a mini lathe if you go for slide mounted turret.
