Bulk Metal Removal, Any suggestions?

If you can't/don't want to put a center hole in the bar, get a short scrap, ie., 2" dia x 1/2" long(or what ever), put a center hole in that, put that between the bar and the rotary center, that will make quite a difference. Ian S C

You could make a TCT hole saw out of some 60nb pipe with carbide tips and bore it on a decent mill then part off ?

i would personally hand it back and get them to do the rough machining !

If you have a stop to trip out the feed, find something else to do while the swarf is being generated.

I made a back plate for a 6" 4 jaw chuck from a bit of scrap steel 250 mm dia x 80 mm thick, as it had been flame cut from a sheet of hot rolled steel the start of the cut was in my bit of scrap, so I had to mount it off center, and work in low back gear, took a couple of days to end up with a very servicable back plate, thread cut and all, my first internal thread. Think the hardest bit of the job was carrying the lump of scrap around town until I got the bus home, thats a heavy bit of metal. Ian S C
