I found a great alternative to the $50.00 starizona counterweight if you need more as I did. I bought 2.5lb weights ( the round dumbbell ones) then had to try to find a way to fit them to the 1/2" threaded weight shaft so would be snug. Found an item in plumbing at Home Depot called "shark bite 1/2" demount clip".. Item #697285910874, put 2 into center hole of weight offset 90* apart and works great. Total cost for one is $5.00.. :jump:

Shouldn't this post be in EQUIPMENT FORUM?

uh, unless somebody moved it, it IS in the equipment forum...... :question:

Always great to see sombody do a cheap workaround to an expensive item (and just why are metal plates with holes in the middle so expensive?)

I used dumb bells with a PVC pipe reducer to fit my CG5 bar.

I adapted mine by way of a wood insert epoxied in place then bored for the diameter of the counter-weight bar.

But will the epoxy hold in very cold temps (may not be a worry for you)......

Cold is a fact of life during Canadian winters. Minus 26 degrees out right now. Good 2 part epoxy will hold up just fine. Even tough the scope is in a dynamic situation, relative to the scope itself the counterweights are static.

Sounds good, I just know from when I was in Greenland that some glues just gave up in extreme cold. Epoxy is different then glue though.

I have a few of those to supplement my real counterweight. I need them back when I work out. :lol:
