when i first learnt how to chase threads by watching Allan battys video a few years ago my dad saw a picture of a nut and bolt which Allan had made. ever since then he has pesterd me to make one, so here it is.
the bolt is 3" long by 2 1/4" wide it has a hand chased 18tpi thread.
I will post a second thread with some workshop pics- because even with thumbnails it will be very photo heavy and you may not want to load them all in in one thread. heres a clicky link to it
