Just an update on the construction of the wooden dies. The ironbark timber I had bought is SUPER hard – so hard it chewed up chisels, sandpaper, and literally vibrated the wood lathe across the garage floor!! In three hours we succeeded in turning the octagonal blanks into cylinders but not much more.
The stuff didn’t really come off in chips, but in sawdust – you just couldn’t penetrate it and cut it.
So on to plan B – I think I will find something “softer” but still hard, and sandwich the wooden die in 6mm plate steel. I can use steel sleeves in the wooden die where the pins are located, and weld the ends of these sleeves to the plates to hold them together.
A few pics to follow and another session in the garage to see what I can find in my timber rack.

|Three hours of frustration, tear outs of endgrain, and still a long way to go!|
