A question for all my slingshot buds: I'm working on my first slingshot using birch multiplex. It's 3/4" (19mm) and I'm making a copy of a Bill Hayes target shooter that's been scaled down by about 20% My question is, now that I have it shaped, rounded and rough-sanded, it seems like it might be a bit thin, but maybe I'm just imagining things. I know that multiplex is pretty strong stuff, but I didn't laminate anything additional to it to make it a bit thicker. So, my question is to the folks that have made slingshots from a single piece of 19mm multiplex, will this be strong enough for at least one layer of TBG? Maybe two? I will be certain to test it, but I'm wondering before I go there if anyone else already has experience with this. And, just FYI, this is the stuff with a lot of layers, not the cheaper stuff. Thanks!
