how to clamp pipe vertically to milling table?

You obviously ARE a newbie - You got a lotta nerve starting a topic on MetalWorking!

ahem.

Most people with rotary tables have a lathe chuck to fit it. That would be the ticket in this case.

Big vee-block would be easiest

Otherwise, U-bolt it to a slotted angle plate. You would have to make sure it clamps vertical in the 2nd plane.

If you have 2-4-6 blacks you could bolt them together at right angles to make a Vee-block.

Vise and a pair of V-blocks?

--If you can move the head of the mill to somewhere other than the top of the table you're golden. Clamp pipe to side of table, move head and go for it. There's a very neat widget called a Verti Vise but it ain't cheap..

I've never thought of that. I wish someone that knows the many uses of 1-2-3 and 2-4-6 blocks would give a dissertation on their creative use.
