the company is called traceytools.com  the die i got was a 1"x24 BUT its a whitworth not BSC. the thread pitch is exactly the same, but the angle of the thread is very slightly different. think bsc is a 65degree cut, WW is a 55degree cut. i got it on their advice and it worked a treat. i was convinced my forks were scrap, but they sorted it out lovely. also bought a 2" die stock off them for 9 quid bargain! so die, die stock, postage and vat came in at £36 total. but if you are coming on the london ride, you are more than welcome to borrow it?

Matt, you and I were talking about this on the pm earlier bud.

Andy (58delray) and I are always posting stuff up and down the country to each other so if we send this recorded between us and then back to you, could we borrow it ???

It would be really appreciated as my brother has a set of forks that need too many washers on to tighten down so a few new threads at the bottom on the steerer would be ideal.

Let me know if we could borrow this and we'll get it back to you asap mate - deffo send it to Andy first though as he needs it sooner than my bro :daumenhoch:

Spen
