I use a cranked ring spanner as per LAB, but the offset isn't as deep, so the process is awkward. I've also used a box spanner. Would be useful to be able to check the clearance after tightening.
Can't be that difficult to find a Brit bike mechanic on a particular Hawaiian Island. I'm sure Bill mentioned his home island on here.
Edit: Maui, it's in his posting profile.
