Some drawings would give a much better idea of what it is you want to see who might be able to assist.

Looks good though, nice.

Cheers, it was a pleasure to make these parts and good practice too, and really this is the sort of collaboration I am hoping will grow on spudfiles - it felt much better to do this for a lovely blade than for money, this way both members end up with unique parts in hand.
