Bamboo back ??
« on: March 01, 2011, 09:22:00 AM »
When doing a multi layer all wood bow with a bamboo back, whats the best way to glue it all up.  I realize that the BB needs to be whole with all the nodes intact.  So if I were wanting to lay everything in a form and glue it all up at once, how would I do it with that bamboo on the bottom?

I've not tried this with boo but when I add choke cherry bark to a self bow(radiused back) I use a piece of blue foam board as a pressure strip. The blue board has enough give to contour around the boo nodes and rounded crown but still enough rigity to maintain good pressure along the bow.
Make the most of all that comes and the least of all that goes!

I was thinking something like that but along the lines of cushion foam.  That foam board doesn't sound like a bad idea.

Are you gluing the riser in at the same time?

build a reverse rubberband form putting the bamboo on top.

I was going to try to do this (boo on bottom) with the modified KennyM form that I just used. I decided it would be too hard to keep the boo from rolling to one side and causing bad glue lines or twisted limbs. I glued the osage lams, a parallel and a taper together with the power lam in between them 1st. The next day I glued the boo on the osage using the top of my workbench and blocks under the limbs to retain their reflex. Ended up with great glue lines.
