Milling question.

Thanks Bogs, ya round column 12" wide at the base, the bolts are 9" apart, if I use a rod 4-1/2" long I should be able to work out what shims to use under the bolts??? or am I wrong.  :doh:

I lay a piece of 8" square, 4mm glass on the table.

In the drill chuck, I have a dti clock, mounted on an arm. (Piece of bent 1/4" rod will do).

This allows the clock to describe an 8" diameter circle on the glass, showing high/ low areas.  :thumbup:

Simple, when you've done it before.......   :D

Thanks David, the only reason for the 4-1/2" was that it is the spacing on the bolts, and if I halve the reading it should tell me what spacing I need, glass is a good solid medium.  :thumbup:

Bernie.
Are you saying, "ain't got no clock" ? So, using feelers under the rod? :scratch:

No mate, I've got the timepiece, all I'm trying to say is , if I use a 4-1/2" rod (with the "clock" on it), if it reads 0 on one end and .10 on the other, I should need to put .05 under the bolts on 1 side, right or wrong.  :doh:
