Hello,
Im looking for a really simple to make propeller balancer, does anyone have or know of any free plans that are super simple.

Im wondering if I couldnt just take a couple pieces of pvc, and drill a hole through each one and insert a metal rod through them and put the propeller on the rod. Sort of like this basic drawing I whipped up real quick.

Would I have to create some sort of hub, or would the metal rod need to be aproximately the same diamater as the hub on the prop or could it be substantially smaller? Im assuming it would have to be real close in size to the inside diameter of the props hub so that it doesnt just "sit" on the tubing. But Im really not sure, so if anyone has any really simple plans with easily aquirable parts from the DIY centers to create a balancer, please let me know.

Thanks,
