Looking for dimple tool

[Mark Fairchild]

I’ve seen this before but now I can’t find it. I don’t know if it’s a pyrography burning tool or a special drill. It makes a small raised dimple in the wood for embellishments. I have burning tools, see pic, that makes a concave burn. I’m looking for the tool that makes a convex , raised dimple.
Thanks in advance!

I think what you are wanting is a cup burr.

 

[Mark Fairchild]

William, thank you Sir! That’s it.

You can also accomplish that without burning the wood, (if you don't want to burn the wood) by using a small punch to hammer into the wood. Then using a wet cloth, and a small heating iron, you can swell the grain, and it will rise into a small bump.

A dimple is a depression. No such thing as a raised depression.

Thank you Donna. Good info!

An ancient Japanese process similar to what Donna described is ukibori. The very slight difference is the depressions are created in your wood piece and the surrounding area is sanded, planed or turned down until the depressions are no longer visible. Any wet heat source should work, I've only steamed over boiling water to raise the depressed area. The depressions can be most any shape. I've only done it in flat grain, might be interesting to try in end grain.

I have a set of cutters somewhat like plug cutters that are used in a drill press. They create little raised domes in diameters around 1/2". They can make recessed domes like William showed or little button like domes to be glued on. The cutters appear to be old, I've never seen any modern equivalents.

That sounds very interesting, I may have to try that sometime.
