We've enjoyed our first shake down sail of the season but our elderly genoa halyard sheaves (the lower ones) have finally given up the ghost. Frankly the squealing could have woken the dead so replacement is long overdue.

There is nothing wrong with the sheave boxes but I am having a bit of trouble sourcing a replacement sheave (38mm/1.5" x 13mm/1/2" with a 10mm hole or larger). It's a Kemp mast and they are aluminium with a Tufnol bush on a 10mm steel pin. I can't believe we're the first with this problem, and it would appear the other mast sheaves have already been replaced with plastic (acetal?) so any advice and/or suggestions out there? Plan B is to make them but I'm hoping for an easy way out

I've also posted this on the Facebook group; apologies if you are getting deja vu
