Hello.
My design calls for 38 rod clamps that can hold 1/4" steel rods at 90 degrees firmly if the set screw is tight, yet not be wider than 1/2" themselves. I am looking for a cheap catalog where I can order those parts without burning a hole in my wallet.
They sell them at chemical laboratory supply stores for ring stands but they are very expensive usually.
Do you know any good supplier to buy them from cheaply? I would prefer steel over aluminum.
Thank you.
