Re: [atlas_craftsman] solid headstock spindle?
- I have. Took a couple of tries to get a really good working one. I left it
solid and just put a piece of steel in the chuck and turn a point if I want
to turn between centers. I had to finally thread the spindle on the 109 as
I couldn't ge a thread that was perfectly aligned on the big lathe. It
looked perfect..just had wobble when I installed them. You have to either
start with a 1" piece and turn it down to (.505" I think?), or weld a ring
on a piece of stock just over 1/2". You also must have a polished finish on
it as it is also the bearing surface. You don't want to harden the spindle.
So yep, it's possible and I did it..but if I have to do it again I will buy
one from Bill.

Anyone make their own headstock spindle out of cold rolled steel? The
spindle seems easyenough to make, but does it have to be heat treated
and hardened after making?
Would making it solid make a better spindle, or is there an absolute
reason that it must be hollow?
- I figured as much, I did get two quotes from them. $1125 was with the taper
bored out and $820 was a solid piece. So they'd charge $300 to bore out the
I'm just gunna buy one from homeshopsupply.com and be done :-) I'm going
to get the 3/4"-16 thread, and bore out and tap my backplate for my chuck
using my Mill :-)
I'll keep eveyrone posted as to how that goes...
thanks for the help all!

One reason for the cost is asking for .001" tolerance everywhere, when you
don't need that tolerance. Try drawing it with only tight tolerances on the
bearing journals and the chuck shoulder. Don't ask to bore the taper,
unless you really can't do that your self., and have to have it.
My first experience with a machine shop netted the same price structure,
because I had toleranced everything to +-001" The owner kindly showed me
how to decide what was important, and what wasn't, and we substantially
reduced the price.
With looser tolerances, they can do a one-off on the manual lathe at the
back of the shop, rather than write code for a CNC machine.
And don't forget, there are hundreds of machine shops. You just need to
find one that's hungry. And friendly to likeable fellas <grin>
