This may be more research than you want, but the process of adding both a stainless rim and a teak rim to an existing wheel has been discussed and described on the two Grand Banks owners forums.* You have to be a member to access the archives (I think) but there is no charge for this.
The reason you need to check both forums is that the various processes have been discussed on both of them.* There is one post, a step-by-step how to do it description on making and adding a teak rim that was written by Mike Negley who is one of the two people I'm aware of on the planet that know more about Grand Banks and things like making wheel rims than anyone else on the planet.
The sites for the GB owners forums are http://www.grandbanksowners.com/index.php
* and* http://gbbeacon.com/phpBB2/
.* While the first site is the more used, the second site is the one with Mike Negley on it.* Both sites have fairly user-friendly archive search functions similar to this site.
There is at least one company--- I believe it is in southern California--- that will make a stainless rim to size for your wheel.* I've seen this company mentioned in several posts on the GB forums but I can't remember the name.* Perhaps someone on this forum will.
