Tramming round column MD30

[BillTodd]

For what it's worth...

For my NuTool MD500-30 (RF30 clone) I levelled the stand, then shimmed the base until the table was level.

I trammed the head, with a dial gauge mounted on a long bar (horizontally) mounted in the chuck so it could spin around several inches to the left, right, back and front of the table. I used a smooth parallel block between the rough-ish table surface and the dial to get a consistant zero.

I shimmed the base of the column with the thinest shim stock, until the it dialled zero (+/- 0.001-2) all around (the column flexes more than this if pushed :()

BTW I stripped the machine and rebuilt it, from the floor up. The columns are shimmed from new!

Well my collets and drawbar have arrived and I would have been playing this weekend if the builders working in the kitchen hadn't fractured a gas pipe. So had no heating this weekend and stayed at my son's instead. On the bright side, got to watch most of the 6 Nations matches!
