"I actually ignored the advice here and grabbed a piece of bamboo floor boarding lol." Imagine that,
Good thing you're capable of picking out all the good parts. I know you stopped there but some other things were written directly after that little tidbit. Namely "not because I think you guys are wrong but because I want to see how it works and to what extent I can push it". Probably completely irrelevant to someone of you're comprehension, but thought I'd repeat myself anyway.
I'm sure we have a whole new slew of members now and none really remember me, but I'm not really one to "follow the grain". When I'm making a bow for money, to pay a bill or to fill a request, it's with elm or yew with ipe, rawhide, or glass/kevlar backing...not bargain materials I can find laying around like these little things.
For everyone's information, I carved the hell out of the bow and did eventually get it down to 35lbs. The bamboo flooring has a contour to it and that had to be taken off, then it had to be shaved from it's 3/8" thickness down to about 1/8" of an inch. The oak and the bamboo I don't think mingle well for this particular bow, though, because it's still pretty stiff. The limbs are a little thicker than 1/4" and I don't want to shave any more off. I wish I hadn't shaved the bamboo down, though, because it looked cool when it was strung up but now it's too heavy for the missus, too light for me, and doesn't really have near as interesting a look. I am certainly going to do another one of these but the other way around...bamboo flooring for the belly and then I'll back it in whatever else I can find. On to bow #2.
I found a couple random pieces of oak that have great grain, but were only 4ft long 1/4" X 3" chunks. I slash cut two of them for a splice and glued them together, with a third piece glued on top (think "pyramid"). I'm going to add an additional 8" piece of 1X2 oak to the center and cut it all out to be similar to a paddle bow, and I may blend another piece of oak on top of the splice for a little more support. I'm probably going to back it in glass and leather, so I know people here are going to boo/hiss me for that but neener neener neener. I've got a box of rawhide from my last bow...I might see if I've got enough to back this one.
Something I would really like to do is have a bow backed in a natural wood finish. Has anyone tried using veneer for a quick off-the-shelf backing?
