I want to see a pic... Set screw? I think my Trex is clocked in the tube with a hole and pin in the holders and then two clamp bolts with nuts and 4 in the frame that were CAed in?
Update on the set screw drama. I got it out without up setting the threads on the belt pulley. If I try to drill it out, I could of damage the threads. That pulley is almost $25.00. I did good, no damage done. She's ready now. Just need to wait on the weather to change. I've heard that rain is not good for electronics
