I am wanting to build up a stock of these couplings for shafts not over 1" . I just want to have some on the shelf for when I want to build something. The problem is that new, they are expensive for a bunch of them.
I've checked McMaster and Ebay but still, for a number of them, they are expensive.
Any ideas for cheap other than make them? Hose and clamps may work for very small stuff.
