Here is yet another low cost counterweight idea that I know is already used by many as an alternative to costly counterweights.
Because of my additional AP gear on the scope side of my mount, my stock counterweight isn't enough to balance without sliding it WAY out to the end of the bar (and I want to keep my counterweights closer to the fulcrum). I looked online, and like everyone else, I think astro counterweights are way overpriced (and then there is the shipping added on).
So a friend of mine who has old barbell weights he doesn't use, brought in four of his 2.5 weights I can keep for free. They are nice and small in diameter (not much bigger than my stock counterweight). I already have a lockable collar so I can sandwich however many weights I need between that collar and my existing counterweight to keep them mounted solidly. I just need to find a spacer to reduce the center hole down to the 20mm of the counterweight bar. I think I'll clean them up and paint them white to match.
They are 4 3/4" in diameter with a 1" center hole, and 5/8" thick.
EDIT: Already found the spacer. 1" PVC is almost a perfect fit inside and out. Also found a 20mm collar to lock them in place.
