Mini bobbins
HI, anybody happen to know what thread is on the BL Mini exhaust rubber bobbins, tried measuring, certainly not metric, but then again not a direct
match for imperial. I have two new ones but no nuts. Hope somebody can assist, thanks, Ray

I've noticed that some replacement bobbins imported from China / India have had UNC or Whit threads on them.
I guess it's a combination of old machinery and less turns of the spanner to do them up.

The nuts will be 1/2"af, easily mixed up with 13mm for the M8 thread so don't try to force them on if they don't go easily.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

From memorym Whitworth and UNF (or is it UNC or BSF??) are idnetical up to a certain size, about 1/2 inch diameter; then are incomaptible
afterwards.
The answer will be out there if you google..
