An old standby in a modern world

There is an earlier thread here about how to make a p-30 half-tube for winding outside the model. Good information! Now I am charged up to build a system including a couple new stooges and the Piserchio claw hooks. I notice you can buy them for Wakefield (aka F1B) and Coupe D'Hiver (F1G). What I cannot find is what these Hooks weigh.

Weight is always a challenge for a durable, warp-free P-30 design. The hooks for a (say, 12 strand .125) Coupe would have to be designed for at least three ties the torque/tension of a ( 4 strand .125) motor which I mostly use. My amateur materials and methods cannot match the strength to weight levels achieved by the professional shops that make them. But I would like to know where the bar is set for a professional Coupe Piserchio Claw (even though it is overkill for my requirements).

Since the consensus seems to be that professionally made P-30 Claws are not available, I would still appreciate the weights of store boughts and weights achieved by other home-made Claws. I have been working almost full time for a week using my El Cheapo Chinese mill, lathe, hobby shop aluminum and Hardware Store aluminum hardware. Several dozen failures/losses. No wins good enough to weigh..but I am guessing over two grams. Heck, my transmitter weighs less. But no, I did not build it.

Thanks, Thrman
