A few months ago, I struggled to hack out some Elm on a canal boat.
No power on the boat, so a power file etc. could not be used.
A mallet and chisel wasn't used, due to lack of space.
We did the job, but it got me thinking.
Take a old hickory handle and shape.
To reinforce the working end a metal strap was fitted and riveted on.
5.5mm rod cold formed into 60deg countersunk holes.
The strap was warmed up, until spit boiled. Fitted and riveted.
Case hardening the tip.
The blade was a bit of scrap. Hardened and tempered, after forming the cutting end.
Originally it was shaped to 25 and 30 Deg. It should be lower, I think 15 and 20 deg.
All the parts made.
Stained and waxed.
Trial use.
You can see my pencil line, This was a oak off cut.
I made a few mistakes.
Blade angles are too steep.
The wedge needs to be steeper and shorter, but it works.
The working end needs to be wider.
But as a scratch build I think it is a good prove of concept.
