Start slowly an gradually, make template for the camber ,use dry heat from electric burner. That/s for a vln bow. For a gtr sides I would make them .075-.080 max especially if the density is high .Pernam density ranges from .090 to 1.2 I would spritz lightly with water. If will take a gradual heat say 350-400 deg F. vy slow to bend depending on. density

if talking about bending sides and not bow making, may want to ask Bruce Sexauer over at the unofficial martin guitar forum.

good idea.

The set I bent went much easier than I expected. It had a lot of runout in spots, and that worried me, but was less of a problem than I thought it would be in the bending stage. It bit me later when routing for the binding, though!

When bending wood with runout, such as that striped Pernambuco, or curly maple, I will usually only wet the inside surface. Water on the outside weakens the bond between the fibers, and they can peel up. In some cases it can help to glue a piece of paper onto the outside surface. This helps prevent splits by holding the fibers in. You can use CA or Titebond.

thanks Alan, that is a great tip and actually spot-on as the wood (specially in the sides) has some sort of flaming/ripples.
