Backing thickness
« on: May 03, 2016, 09:47:41 am »
I've got a maple backing on this bow I'm working on, and it's about 1/8" thick, but I'm going to have to take that down a little bit due to clamp-impressions from when I glued it down.  How thick/thin does a wood backing need to be?  Does it matter?  Is a thinner backing more prone to break because it's weaker, or less prone because it's more flexible?

Thanks folks!

I cant tell you how thin you can go, you just never know. I like to start around .187 and work it down to .125. I see no good reason why yours wont be fine if the grain and health of the backer is perfect, as it should be.

How bad are the dents?  Maybe you could steam them out with a wet rag and an iron.  That has worked for me on small/shallow dents.

I would try what TimBo suggested first. I've never worked with maple but with hickory backed bows I've reduced the backing to just over 1/16" with good results.

  You can steam them out but I would be worried that they broke some fibers. I would go with your plan and sand them out.

Like Pat, I've used hickory less than 1/16" thick... some of them I've reduced after they were glued on.
