Cromwell Tools sell 1/16" BSP taps (but not apparently dies)

Mick try Tracey Tools in thier catalogue they are about £5 each

Roy, Where did you find 1/16" BSP in Tracy Tools cat, not in my Winter 2012 paper catalogue nor on their web as far as I can see?

Can you not re-cut the threads to something a liitle more common? (Or as I did, solder the buggers on)

Steve

Appologies again I must have been having a senior moment ( at 78 I get one or two)

it seems that 1/8 bsp is the smallest size This I have just confirmed by Machinery Handbook and Zeus

Mick, Have just seen an advert in one of the vintage steam mags for a company who may be able to help. They claim any tap,any die, any thread. Contact details are 01454 324564 or http://www.avontapdie.co.uk Hope you will find this info of help.

Machinery's Handbook 27th Ed (2004) clearly shows 1/16" BSP as being part of BS 21:1973

The other alternative is to by unmachined elbows which allows you to thread them with whatever you have to hand – 5/16×40 or 5/16×32 is what I use and always keep a few elbows in stock

I,m doing a recovery job on a Stuart Turner S9, the drain cocks are threaded 5/32 ME, 40 TPI, the oilers on the main, and big end bearings look like 3/16 ME. The inlet, and exhaust flanges are also ME thread. ME or any fine thread, ie., UNEF would be ideal for the little stuff. Ian S C
