A couple of notes on the spindle front:
1.) I still have the RC spindle [url](http://www.buildlog.net/blog/2011/09/ne ... r-spindle/
)[/url] in my basement. It's actually further away from being mounted now that I've moved my test rig to the garage. Although,
I would have never run the DC spindle in the basement, so maybe in that
respect it's closer?
2.) I have a new mount for the CNConabudget.com spindle that I've been
itching to try out (it was 3D printed on an ORDbot from black ABS). it
brings the bit a lot closer to hte extrusion. That fact mixed with the
alternate mount configuration (lead nut moved to the side as shown in one
of the previous pictures on the forum) means the Z axis is A LOT stiffer
than it's ever been. I had ordered a rigid coupler (5mm to 8mm) so I could
test out that config but I don't think it's going to work. The OD is too
big for the space. I have another in mind bud haven't ordered it yet. I
might try to make one instead.
3.) I picked up a Dewalt
amazon the other day for about $60. It came with both 1/8" and 1/4"
collets and reminds me a lot of the rotozip I use to have. But, it's about
1/3 the weight as my old rotozip. I've drawn up another u=shaped mount
(similiar to the UHMW mount I use for the dremel) and I just need to cut it
out so I can mount the Dewalt. It's wicked strong (5A!) and noise wise it's
no louder than my knockoff dremel. It's a little bulky, so I'm not sure if
it'll work or not, but for now that's moved itself up to 2nd on the list of
things to try.
I like the RC spindle idea a lot, but as I've said in previous posts,
there's a ton of wiring that goes along with it and some fixed assets that
will have to be designed into the mount itself (ie ESC)
As it is, I have two Shapeokos in my garage but neither of them are fully
functional. The one is the alternate design (with the side plates running
hte wrong way) and that isn't solid enough to cut with. And the other I
have taken apart in order to mount up the drive shaft style dual drive
system discussed on another thread. Which reminds me... I need to get back
to work on that
Shapeoko #0 - a couple of upgrades.
