I have been pondering this for a while because the local sheriffs camp has about 20 16s and 14s that we are helping with. The rudder systems are horrid. Mostly old non adjustable castings. I had an idea for a simple modification that I would like to run by you guys. The old castings use a ss tube in a hole through the upper casting that is flared on both ends to hold it in place. What if I drilled that out and drilled/ filed adjacent to it to make a slot. Then replace the tube with a 1/4-20 bolt and nut with some star washers for grip. This could be adjusted in the newly made slots to get a proper lock down. The slot would only have to go towards the cam since these old systems are always loose.

What do you guys think?
