New spindle needing new mounts

[Cncparts]

Ah yes I forgot about those profile gauges, very handy things, been meaning to get one!

Would be nice if there was an easy way to get it to an electronic vector...!!

Thanks for the help

This is how I do it.

Get a photocopy or photo of the profile, fire up Sketchup and import it as a picture, use the scale tool to resize it to the exact size you require, on a new layer use bezier curves to draw around the outline of the picture, print result at 1:1 scale.

What your wanting to do is called tramming the spindle and using a Set square with Steel in Collet is not good enough and won't be accurate.

Easy way is to get a Piece of round steel bent 90deg that fits in the spindle, make sure it's stiff and ridged so doesn't flex. Make it has wide has your Bed then mount a dial gauge on the end. Then sweep around 180 deg and see how much it changes, if your spindle is trammed correctly it should hardly move in each Axis direction.

The wider the sweep the more accurate it will be.
