bamboo flooring bows?

[stringstretcher]

I know that some of you have made bows from bamboo flooring.  I would love to see some close up pics and get the deminsions that you used to get the poundage that you wanted.  I have the material to get started, just looking for different ideas and imput

thanks

I made a pyramid from flooring backed with bamboo.  It was 66" n/n, started at 1.5" width and tapered uniformly to 1/2", so it was only 1" at mid-limb.  I made the mistake of getting a really nice bend at nearly 70lb@28" and chose to stop.  Too much stress on the bow as it turns out, a limb snapped.  The design would work well at 50lb@28".

I used bamboo flooring for the core in this bow.

I made a trial bamboo bow. It was 48 inches long (the length of the board) and 10mm thick. the bow was 2 inches wide and made like a pyramid. I tested it to destruction. The bow eventually broke in tillering at one of the node areas on an edge. I think a less stressed bow would have been OK.
Bamboo flooring can come in idfferent forms. Some has the bamboo on edge and some parallel to the surface. This may make a difference to how the material performs.
