Yes ozzie - I have seen some other posts from you explaining this. I used to do that but now ask Giles for the parts and have a go myself. Heads are pretty easy - drill into the neck and up into the head and put a pin in. Super-glue is also so good these days, I never bother to solder any more. If I'm not certain what to do next - I simply ask Giles - and usually get a short tutorial by e-mail!!
No wonder he's my favourite supplier. Anyway, glad you liked them. - johnnybach
