Swirls

[coltpax]

I saw a knife at a recent campout that had swirls in the blades finish. You could feel no difference in the texture though. They looked about 1/2 in diameter. Any1 know what these are called and how to make them?

Engine Turning or jeweling like this?

[coltpax]

thats it exactly. how do you do that? Or is it an ancient chinese secret and if you told me you would have to kill me?

Colton - I've done some small engine turning with a drill press and a pencil - use the eraser as the polisher - just a little down pressure and you have a circle mark - over lap them as you choose for a pattern. The smoother or more polished the part is to start with the better - I've also used a wood dowel rod - it holds up better than the eraser. Thats just the cheapo way I've done it to get the job done. -JK

Ancient machine shop task. No big secrets, just diligent work that takes time to do it right. A mill is the tool for the task, but it can be done on a drill press if you apply yourself.

Take a look at the Jantz Supply Catalog. Page 64. Cat. # ET1 and ET2.

It is a Jewelling tool made to be used in the drill press.

I use valve grinding compound on a dowel and get results I'm happy with.

I have used the eraser method but found the eraser would tear and have to use several. I haven't tried the dowel method yet. Thanks for the insight. William

OUTSTANDING! I like the look and the method seems simple enough. Will keep y'all posted on the results. Thanks!
