Picked some up at Harrogate show quite a few years back and eventually used them on an ally Sweet Pea saddle casting, the bloke at the foundry had been far too enthusiastic fettling them and ground away all the machining allowance, managed to build the casting back up to where it should have been and it machined beautifully, which reminds me, I really must get and finish it, only saddle tank,cab and plumbing to go! Oh nearly forgot, painting as well.
