Don, maybe you are right. Can you point me to an example of a 5C
drawtube system?

I had to order a new nosepiece and protector from Royal when I
got my L-00 spindle -- but I understand that Royal no longer sells these
for anything but CNC machines these days. (Scott Logan - is that
right?)

The handwheel type is fairly easy to build, if you can get some
tube which will fit loosely in the spindle, and which you can internally
thread to match the collet thread. The lever system is quite a bit more
complex, and it is easier to find and adapt one than to make one from
scratch without one to examine.

Haunt e-Bay with the Morse taper and spindle bore and length
measurements and you will eventually find one.

Maybe others can point you to someone who still makes them for
manual machines.

Enjoy,
DoN.

What DoN said. I made my own handwheel type, including the protector.
I made the handwheel from aluminum plate, used an aircraft torque tube
ball bearing for the thrust bearing, and a tube of almost perfect
dimensions of 4140, just had to thread the ends. However, I didn't
get the performance I wanted (runout) until I replaced the homemade
adapter with one from Royal. Just tell Royal the exact model of your
lathe and they'll tell you what adapter. As a bonus, you'll find out
what your headstock taper is. Mine wound up being a shortened MT5.
Good luck.

Get ready for the sticker shock at Royal. iirc, about $1500 for a complete
snap-handle system, depending depending.

I have two machines with these snap handles/draw tubes, a Clausing
Colchester and an Enco, both 13". The Enco is actually pretty nice bec it
has cam lock chucks, making the swap real easy. The CC req's a big-assed
spanner wrench, and is a real pita.

Snap handles are very nice, but are more for production. For prototyping,
the Bison collet chuck deal Karl showed seems unbeatable for the price,
altho mounting it will certainly require some care.

The only part I bought from Royal was the taper adapter. It was
expensive, but less than $200 IIRC. The rest is pretty easy to make.
I put pics in the dropbox a long time ago. Let's see...

This one has my homemade taper adapter. I never could get less than
..001-.002 runout upon reinstallation.

The nose adapter is aluminum, works well. At the time, I didn't have
a shaper and hadn't heard of the cross slide as hand shaper trick,
filed the keyway.

The handwheel was made of 3/4" al plate, with a separate piece for the
hub, bearing carrier is mild steel, tube is 4140.
