I am looking to do some decorative engine turning on some stainless steel. I will be using my drill press and cross slide vise for the setup. Any suggestions on the abrasive? I am looking for about .250 swirls. Thanks in advance.

See here for engine turning:

I suspect what you really want is "Jeweling". Try fine valve grinding compound on the end of a wood dowel. You can use just about any abasive depending on the effect you want and the material being jeweled.

I used a roll of emery cloth, tightly wound then chucked it into my drill press.

Cnc automation makes it easier, but if you start by drawing with a pencil a square hatch pattern it works well.

The old method is wood or rubber dowel with polishing compounds.

My site, www.alltel.net/~decofer (http://www.alltel.net/~decofer) the harley dash pictured (halfway down page) was too bright to ride without glasses in sunlight. The angle of the tanks put the reflection right into my face. The studebaker dash was aluminum, 49 inches wide and a pain to damascene on the tabletop drill press.

Eastwood automotive sells kits by the way if you are bucks-up and in a hurry.

Brownells Gunsmithing also has Kits and parts for engine turning ( AKA Jeweling and Damascening )

Yes, see www.brownells.com (http://www.brownells.com) for ideas. One method they suggest (and sell the bits to do) is a small round wire brush, with an O-ring around the bristles to keep them from splaying out too much. Use with grinding compound (which Brownell's also sells).

Another thought is one of those round Cratex rubber-impregnated abrasives. There's a bunch of different ways of doing it.
