I am building a new for old loco boiler, total boiler length is only 6" and it is old. The fittings are 3/16 and although I worked the pitch out to be 34 tpi im guessing it is 32. Now is it likely to be ME or BSF (or other?). Any help greatly apreciated. Thanks.

Hello.

It might help to know that Stuart Turner, pre WW2 had a series of standard threads that they used. A list was printed in their catalogue. One of these threads was 3/16" X 36 TPI used on boiler fittings. We have a number of these on boilers, notably the pressure gauge. Taps and dies are available from Tracy Tools in their Whitform list.

Regards. Mike.
