Closest I can come is a piece of brass pipe. 1 3/16" ID. Decent thickness, 4" long. Would that work? If so, you want me to slice it to 3/4" pieces? It'd probably chance less shipping damage whole. I'll need an address.
hey, 'van, check it out...the copper over the cheap pvc from a previous attempt. this outta buy me some time until i can do some filing work on the beauty brass pieces:
