Ha, ha, yes my horrible spelling. I did mean "cranking" thank for clarifying for me. My thought is that your linbs being wood putting pressure on metal Could cause weakness as they bend and suddenly stoping without any buffer between them. If I understand correctly metal doesn't bend easily . I worry that eventually the wood will rub off within the limb bolt area. I am not a building guru by no means . My question is there a buffer between the limb and area which its bolted to, and how much vibration is being placed in area. If there is too much it could leave to some substantial wear. I wish I could see under the limb.
I certainly don't want you to get hurt.
So if your using one of those arrows then it must like a straighter , stiffer ,arrows.
Very interesting .. Please continue with up date.
The thought of making a take down from a metal pipe as a riser and wood for the limbs. So Please continue. When possible.
