Ed, On tight situations like this I've even drawn it out to see how much room I have to play with.

Ed - nice work so far.


My thought would be v-blocks, angle plates, clamps and packing material.  I used a similar set up to hold a 3" burner tube, whilst I drilled it with a hole saw.  This was on a pedestal drill, with the table angled and it coped very well.  

   
   

I didn't have an angle plate so I made one.  Whilst it isn't a precision one (I will mill it square eventually), it certainly did the job and was cheap to make out of scrap I had scrounged

   

On a milling machine with tons more rigidity you should be good to go.

I'm liking the sound of the V-blocks. I'll try working with those and see if I can rig something up that will be rigid enough. I plan on drilling up to .75" and then boring to the .930 final dimension.

Thanks guys.

How about using an aluminum plate (or a piece of 2x4 for that matter) attached to the table?  Mill your v-groove down the center and then end clamp your parts to that. Then you can drill & bore through into the sacrificial base instead of your v-blocks / mill vice.

It seems to me I've seen that suggested here before.

angle plate bolted to the table with some packing under the part to raise it off the table, doesn't even have to be precision so like Willie said a chunk of 2X4 to clamp the tube too will work.

I wasn't visualizing this at first but I think I see what you're saying now. I may play around with a combination of the angle plate and V-blocks.

I got some work done on the clamp knob this evening.
