Gentlemen,

Thanks for your responses. I have found the articles you mentioned. So the complete list of references is below.

I intend building such a steam generator for my 5" G Simplex which I am finishing (started 40 years ago) now that I am retired.

I have a vague memory of a Model Engineer article some years ago
describing how someone made a steam turbo-generator from a modern pocket dynamo LED light.
Can anyone tell me the reference ?

I have looked up some indices of ME and found the following
references to steam turbo-generators but not the one I am after:

When will overseas deliveries of ME start again ? In Germany my last delivery was nr. 4635 (27 March-9 April). queries sent to [email protected] twice just gives me a reference number.

Other mail deliveries of items from UK to Germany (and Norway) are prompt in recent weeks.

Thanks for your replies. The boiler maker confirms it was BSB as expected.

It just shows you have to be careful when buying taps & dies at shows, to look not only at the size and pitch.

I see that this was pointed out by houstonceng in another posting on 10/02/2018.

So I will buy some BSB taps/dies. It is amazing how prices vary between suppliers!

I wasn´t aware that 1/2" 26tpi thread could be BSB (brass) or BSC (cycle) thread when I bought the taps and dies. I see that what I have has BSC or BSCY stamped on them. I want to make fittings for a commercially made Simplex boiler, so I want to know what is normally used for boiler fitting threads. The difference is in the angle, 55 or 60 degree of the thread. I will try finding out from the boiler builder. The drawing does not specify which should be used.
