I'm almost ashamed to show my first effort here next to some of the very elegant hangings I've seen in this thread. My new Kelly 3.2 double bit arrived in England this morning and I spent the afternoon joining it to its helve. It is extremely difficult to find hickory in the right size handles to fit a double bit axe in Europe, so I re-purposed an old hickory pick handle. The grain isn't anything to write home about as it slopes across at about 45 degrees. But I think it will be alright.
This isn't finished, but it's pissing it down with rain I have stopped for the night so I thought I'd show the work so far.
Handle roughly octagonalized with a hand plane. Don't know if my phone camera picks that up?
I used a home made oak wedge.
No electric tools were used at all, and it was all done by eye. That's my excuse for such low level finishing! But, I'll neaten it all up over the next few days, and it should be a tool to be proud of.
