If you install an Infinity Aerospace stick grip, you'll have to contend with a fairly large bundle of wires that must protrude from the stick, near the bottom. Most people just drill a 3/8" hole in the stick and call it a day. But if you consult an engineering book, you'll see that this weakens the stick quite a bit. One solution is to weld a steel washer around the hole. But how do you bend a pair of steel washers to a 1" radius? In my case, I have some very clever and inventive friends. One of them, Keith, CNC'd me a tool to make them. Here they are. Thanks, Keith! Next, I will media blast all the factory powder coating off the sticks, weld a washer on each one, and re-power coat them.
