PekkaNF:
I have been been acutely aware of limitation of my tail stock. Found this one when I was googling around.

There are some systems to tow the tailstock with cross slide. This is new one to me:

Can't use it on my lathe, because the tail stock just does not have enough footing, but on Myford it apparently works.

Lew_Merrick_PE:
If you are going to do that (http://www.swarfer.co.za/lathe/tailpow.php), why not just make a chuck or collet holder for your cross-slide (along with a center index pin set) and be done with it?

Jonny:
Think its Smart and Brown that uses a simple towing latch on to tail stock base.
Far superior to above not only does it pull towards the base you don't have to faff about setting it up to use, dismantle put other toolpost back on, dismantle for next one and so on.

With that link it will be exerting a bit of lateral force, holes may not come out central.

PekkaNF:
Jonny, seen couple of working examples on bigger lathes.

Lew, I have a MT2/1" adapter and QC block for tool holder. Tried it once and tool post had a tendency to rotate under load. The drill adapter was pretty far from tool post center bolt. I was thinking of aligning the whole thing, but there are pretty many things to align to the axis of the hole: Cross slide, tool post, QC holder (vertical and horizontal), adapter, drill...It's pretty easy to clock them straight, but to have them straight and centered? Need a method here, rather pleased if it does not start by chucking the piece I was turning out of the chuck and then chucking an mandrel the the adapter in the TP is aligned to....

I'm trying to figure out if it would be feasible to make a tail stock with fairly long stroke for drilling. Nothing "ultimate" just good enough.

That would be perfect for the deep hole drilling if you incorporated bearings making it a rotary chuck powered by a drill or pulley/belt/motor system.
