Well, haven't been updating in awhile.
Mostly because i was sanding parts. Talk about tedium and boring.
Anyway, I found these little things to be quite helpful. Found them at Lowe's in the hardware section. They are usually in the drawers where the screws and bolts and nuts are found.
I've used them for the inside of the knee area, and also for the pivot joints on the arms at the elbows. They work great.
Here i have drilled out a hole in the knee piston for the screw head, then applied an apoxy glue to hold it in place.
