When I bought my Super 7, I was told that there was a washer missing underneath the cross-slide handle - basically the micrometer dial doesn't move when you wind the cross slide in and out. I tried using the washer from underneath the compound handle (same part number) and it just jams. I then made some different washers from brass shim stock but couldn't get one to the right thickness to prevent jamming or give enough friction to make the dial turn.
Any suggestions?
