Yet another problem solved via Sailnet and this "stale" thread! Followed the link in #20 to Auclair Nautic. Auclair Nautic - Manivelas de winch.
Francois is manufacturing handles for several (probably most) old winches.
I ordered two with a 8 point star spline that both fit my Lewmar 8 and 25 winches. The pair cost me about $325 including shipping (from Spain). Pricey, but gladly paid! I ordered the standard handle and optional locking mechanism. While they are nice looking, the machining of the spline, lock and rotation of the handle is a little crude for handles in this price range. The locks are not spring loaded (as with modern winches). They should be fine for the typical horizontal application, however, I won't trust the locks (leave the handles in the winch) for my vertical Halyard winch. Most importantly...THEY FIT!!!!
Customer service could not have been better.
After searching for years, and having considered doing this myself, I can assure you Francois is providing a valuable service. Highly recommended!
As I feared, the lock on one of the handles betrayed me. I watched in horror as the handle fell out of the winch, hit the deck, and did a back flip into the bay! Unless the lock mechanism is improved I would recommend not ordering (or making) it. It makes the handle difficult to remove from the winch (which is why I thought "It won't fall out if I can't get it out". WRONG! ) and provides a false sense of security.
