drilling out the OEM cassette for a bigger pintle
Posted 07 September 2012 - 01:55 AM
I think it's something like:
- remove gudgeons
- drill gudgeons and cassette to 0.5"
- insert 0.5" stainless rod
Is it that simple? Any problems to watch out for?
I know... I'd rather have the full carbon 1-piece rudder too, but budgets sometimes limit, and I need a Zero or a A5 to fill out our inventory.

I did mine on the boat, a vibrating, chattering hand held drill will never do the job.
Sounds easy, just drill out 0.7mm of stainless, but it gets hot, then work hardens, impossible.
Luckily an engineer working on the next boat in the boat park watched for an hour then came to help.
He slowly chipped out the hole with a 1/2 drill held by hand in vice grips.
Then produced a 1/2" reamer and saved my arse.
If it were not for him my rudder pin would have rattled for ever.
Just remember, working stainless is really easy, so long as you remember how hard it is.!!!

Clew, did you remove the bracket from the boat and drill in a shop, or did you drill it on the boat? I'm trying to be cheap, but don't want to stuff it...
We did it with a hand roll but with a carbide step drill with outermost diameter being 0.5". Was really easy. Working perfectly with Betts or oem.
