engine turn?

anyone got any tips what bits to use

im confused, what are you asking about?

you have never seen egine turn alum or copper sheets...very old hot rod mod

Found this info on a website:

Got a drill press? A wooden dowell of nearly the diameter of the swirl you want to make? Some 320 sandpaper? Light machine oil? OK, then... Put dowell in drillpress, and tighten chuck in two places. Cut sandpaper into squares with sides longer than dia. of dowell.

Choose a slow speed on the drill press, oil the sheet, put sandpaper square face down on sheet, lower spinning arbor to engage paper, hold lightly against sheet for 3 seconds, and raise arbor to see the swirl. Ultimately, you will fuss with speed, grit of paper-360-400- or valve lapping compound, or Kratex sticks. Tinker with kerosene and other lubricants, and practice your layout math, and overlap, and the stagger of the swirls. They can be 1/2"Dia. up to 2" dia. and may be done on many bright metals.  

yea thanks found some cylinder shaped drill bits and got the panel i wanted to do ...but never want to do it again to long to much time to make a 10"x15" sheet

i like makin my own parts

The idea is to use the kit for the making of your own parts. I'm gonna grab one to try it out, looks like it would be a fun tool to have around the shop to play with.
