RE: [CAD_CAM_EDM_DRO] Re: $250 machine pics

basing a little mill on a granite flat is brilliant
idea.
casting in the precision locations could be a winner
too.
now you want similarly simple KISSy couplers and
bearings and backlash?

(i'm posting as i go on this, but i think you may like
some of the solutions!)

for spindles...darn i can't remember the site
name...but it's done with r/c motor and they guy has
sold em on ebay too. vbx bearings has 100krpm bearings
even - bearings are cheap these days. i guess we can
thank roller blades...lol. i know a nice trick to
make spindle heat and linear expansion irrelevant too.

excellent project and totally worthy goal. this
certainly is achievable. i'll contribute too, if
invited. all the ingredients appear to be present at
the same time...
