Re: Semi-good high speed spindle idea? - da-300

> how low did you get your runout on your collet mounting ?

Chris,
The same thing worried me so I bought a .5 inch diameter da-300 collet
chuck for a spindle with collets(ebay ~$80). Collets are available
to .25 inch. Pricy but no runout and a choice of collet sizes.

Unfortunately I haven't got any further. I'm still trying to figure out
how build a spindle that will fit like a mill cutter and not take up
all the z travel.
