I just found the mainshaft cracked on my Barient 22 halyard winch that mounts on the mast. If you've got parts or an entire 22 for sale, or maybe a Barient 23, I'd be interested. Thanks.
Check with these folks, I've gotten parts for my Barient winches from them in the past, only drawback is they are in Australia, so some shipping delays, bug otherwise great service, at least what I've experienced.
Got a pair of 22 2-speeds off eBay for under $250. One of them should have a good mainshaft. The Arco quote for a new mainshaft was about $320 US.
Doing a little research, I discovered that the chrome-bronze drum from my 22 should be interchangeable with the aluminum alloy on the ones I bought. Ditto with the mainshaft.
In this case the guts of the winches are all the same, regardless of what the drum is made of. So, swapping bronze for aluminum on these winches is not going to be a problem. Thanks for the concern, though.
