I want to make prods that are under 12" from nock to nock, with hopefully 40# total draw weight. The modern pistol bow prods are far too long - more like carbine prods than pistol prods.
I do have access to bamboo (both wild harvested and 'processed'), and I understand that constant width lams are best. I think I can find wild harvested 'boo that is more than 10" between nodes, even... If I can't, I'll put the nodes at the centerpoint of the lams. A belt sander on wild harvested splits will give me constant thickness and width lams. I'm figuring on 4 lams -- say 10", 7", 5" and 3" that are 3/4" or 1" wide. I know how to make a tillering tree, even that small, and have a scale for measuring draw weight
The big question I have is which side of the stack faces the nut -- the short lam side or the long? I can see advantages and disadvantages to each.
Other questions include brace height and draw length for this stacked creation. With a 10" length, 2" seems a reasonable fist. All I really need is space to grab the string with a cocking mechanism. On draw length, conventional wisdom for wood bows would say a draw of 50% of the T-t-T length, or 5" in my example...
