sounds like it might be possible to repair by metal spraying depending on line of sight be availbale for the area etc post a pic and ill have a look (its what i do for a living, although we specialise in batches of parts rather than one offs etc, i might be able to kick you in the general direction of someone who can if you decide to go that route).... dont expect it to be cheap though. Best bet would be for the club to collect up a few of them if its a known problem and have a batch done, brings the price down to a vaugely sensible level. Sounds like you might be better with a sleeve in your case, still be interested in seeing a piccy though!
Interestingly (or maybe not) we're currently in talks to do a load of repairs by thermal spray to wheels of a well known ww2 fighter plane which suffers the same problem....
