Question on TD longbow form

[SOS]

I'm making my form for a pronounced TD longbow limb. Not ready to dive into the firehose setup yet so am either going to use rubber bands or strings and wedges. Do you recommend making the form convex or concave? Thanks, Steve

Steve, I would cut my rubber bands from a bike inner tube. A lot will break during cooking. The fire hose is the way to go trust me.RC

I don't know why, but concave seems right.  Maybe because you generally cover the belly with tape and draw the limb shape there and it just seems right to keep the drawing up, where you can see it.  Perhaps someone will speak up with a more scientific reason?

I have had good success using the clamp style form.... allows fine control of pressure and better alignment adjustment ability.  Cost is comparable to the hose, ease of construction is the same.... either way works just fine, but I think you want it concave because it allows the wedge to sit properly, i.e., like it will on the bow, flat.  The wedge should be flat on the back of the bow, and the taper should be evident on the belly.... or did I get that backwards?  Good luck.
