Install new and smaller ones. It’s faster, easier, better result, not that much more money (good leather is expensive) and if you ever put in a new Renner underlever tray you’ll be glad you did.

Your picture amply illustrates the issues of wire condition (looking pretty twisted) and various felt profiles, which can have a significant effect on how check functions with a particular tail shape.

New ones (three different types shown) have a totally different physical dimension to the point that it’s beginning to look like it would be faster to simply recover the existing back check heads. If I were to go that route ........... and aside from getting the grain of the leather in the right direction ............ is it critical to get the leather at a consistent tightness to get some reasonable checking effect?? A procedure involving a clothes pin has been suggested. Comments?? P9111268a -------------- next part -------------- An HTML attachment was scrubbed...
