Does anyone here use a swivel table mill ,or do you pivot a plate holding the center and dividing head for handle work.
I am asking as I have an option to buy a mill with a table that can swivel or pivot +- 20 deg.

Neil,

You need to think about the concept of this machine again.
It won't do what you are suggesting.
You still need to 'swivel/pivot' what is ON the table to cut a 'V' groove in the forearm.
The table travel & spindle relationship does not change.
Actually, I've never understood the reasoning of this machine.

Thanks KJ. With this particular machine, the table or lead screw is still square to the cross slide. But the top 1/2 or the clamping surface can pivot.So the T slots are at an angle to the run of the lead screw.

I saw a cheaper machine that angled the X axis with the lead screw on an angle as well. That machine was only any good in a y axis really. As you said ,when the table and lead screw or together,the relationship to the cutter does not change.

That's a different story. The machine I saw pivoted the lead-screw as well.
The machine you describe will indeed do what you want.
I'm now satisfied that you know the difference. Good Luck.
 
Would you please post a picture or maybe a google link of a similar mill? I've never seen one, and couldn't find one online. Just curious...
 
I don't have a picture, but I was looking at a used Dekel-Maho Toolroom mill- MH-800
The smaller MH-700 is also a good machine.
I have dithered about too long.They have a pending offer on it.
I am not too worried as I don't have 3 phase yet.
I feel I am better off looking for manual ex Toolroom mills that will be coming up for sale as companies either upgrade or close down.
These are very rigid even a well used one will still be in more than good enough order for cue making.

The feature makes more sense as part of a horizontal milling machine. In that case the table can be angled to match the pitch-angle of a spiral to be milled in a shaft (the shaft would be held between centers of a rotary table geared to the table and a tailstock). Think of how one might make a ball screw. If the cutter is a perfect .500" radius, and the shaft is perpendicular to the cutter (table NOT angled) then the cut will be part-elipse rather than half-round. If you angle the table to match the pitch then the cut will be .500" half-round.
