Sorry to bother you guys again.
has anyone compiled a list of therad sizes for the minor?
I have allot of siezed bolts that will need re-taping once drilled out but no idea what type of taps to buy. Ive got some unc ones (bought for working on an american helecopter) but they dont fit!!
Cheers

The Minor uses mostly BSF threads, which are finer than UNC. If you care to list the ones that you need I will try to identify, if that would help.

Ther's a comprehensive list of SPANNER sizes in the members' area technical tips section.
Thread sizes can be fairly easily determined from this eg 1/4" BSW = 5/16" bolt size.
