Post subject:  Forearm contour, bindings

So I want to think about doing a forearm contour on my next build...

I never tried to do it before but I felt the easy part is putting the wood inside and shaping the actual contour itself, the hard part is bindings.

How are bindings done on forearm contours? It seems like it's impossible to do with just a hand router because of the irregular surface. I seen one guy just make a template, is that how it's done? What about the side purfling?

This just seems like a CNC job...

That' the way I've seen it done, using a template. Same for the side purfling, template.
What's CNC? Not something for building guitars surely.

Do you mean an arm bevel? If you don't mind taking an on-line class for a reasonable price this is a good resource. Kent Everette shows you how he does it. I followed his instruction and was pretty pleased with the results.

thanks for the tips. I think that tips du jour tells me everything I need to know.

Sounds like making the template and shaping the bevel to that template is a better way to go about this than making a template for every guitar that gets an arm bevel.

I have some practice to do.

Mike Doolin came up with a really clever alternative way to do a forearm contour. Not a side bevel, but a bent top. He gives a pictorial tute here:

My method, using giant dentellones rather than a solid block http://www.luthiersforum.com/forum/viewtopic.php?p=645146#p645146
