Makes a nice thud but with the axe head thats on there it tends to blunt the axe.

I also think the fact that the axe is aluminium tends to give it too much flexibility when it hits. Maybe a note for future upgrade works.....big steel bar to be fitted.

The linkage was according to Dennis take from Shunt and works really well. (When you remember to fill the CO2 tank, plug the axe in or something similar which seemed to happen every time we were out).

Just to let you know Leo the axe uses needle type bearings where it moves. Quite sure you couldnt see these when you were copying it!!

If you need any further dimensions or templates for parts I am sure I can let you have them.
