You have endless options. I use wood, brass, g10, stainless, mosaic pins, all kinds of stuff.
Thanks Dennis. How are you attaching them? Pins, screws? Beautiful work BTW.
I have a friend that is an exceptional welder. I take 416 and stainless all thread and he welds me 1 inch piece of thread on butt caps.
I use a tap and die lately to thread my tangs. I just saw a video that showed a method I'm going to try. The idea is to use a hex head screw. Heat the hex head up and flatten it to the thread diameter. Saw or grind a notch in the flattened part (think notch in an arrow). Grind the end of the tang to fit in this slot. Drill a hole and pin. You can make this to give some up vertical movement of the threaded hex bolt.I need to find better friends...
