Bamboo, Ipe Hickory Build (Repair In Progress)

I would test the breaking strength of those screw heads...I wouldnt feel safe putting 50-60 lbs on them.

My old subwoofer ripped the heads off 6 out of 8 of some fairly string dry wall screws

colejack3:
 ;D That must be a crazy powerful subwoofer :o

Sanford:
Yea noted on the screws.

I have though of that and did take one precaution by angling the screws done so that the force of the string is directed both parralel and perpendicular to the screw axis. What does this do one might ask????

Well by having some of your force vector pointing down the shaft of the screw, you take a way some of the moment that is put on the screw. If all the force is normal to the screw, then you put the biggest moment on the screw.

But having said that, this doesn't mean anything if the force is to great for the screw anyways! So may change that!

Justin Snyder:
Looks like it is comming along nicely. 

Just for future reference, putting the ipe on the belly makes for a better bow. The denser wood is better in compression for the belly, but in the middle of the sandwich it mostly just adds weight.

Sanford:
Justin- thanks!

And yeah i thought about that too. The whole Ipe in the middle. Probably didn't need it anyways. Mostly pleasing to the eye. I actually love working with IPE. I like how hard it is, because i like to use power tools, and it very hard to mess up. Where as using less dense woods, sometimes I get carried away.... Its heavy and all, but man does it make a fast bow. I wouldn't expect it with the weight, but it performs. In this situation though, i think your right!
