I'm sure the metal centers vary a bit in diameter but are they new ones or re-used old centers? If I have a tight one, a gentle squeeze of the end of the U tube fixes it quite easily. I just had to open up a U tube end to make one fit a bit tighter. What I would like to see is a fairly soft flange -one very old one I had was oxidized and had a bit of a "skin" on it but was still quite soft. And I'd like to see Orthophonic back flange gaskets with the beveled edge extension.

A Friend and I are thinking of making them for our own use given the problems we have experienced lately with ones purchased from an unnamed vender. Those most recently obtained, apparently have poorly manufactured medal centers which "stick" on the tonearm U-tube, to the point they need to be removed from the reproducer and "wrestled" off with a tool! Most needed is a source for the rubber liquid, as we have many original centers and would only need to create a mold. Any observations / comments / referrals would be appreciated.
