Thank you everyone
A tip for anyone who has a go at making a knife, if you find you need something to compress the handle when gluing a masticgun works good, cut a round bit of wood say 10mm thick, drill a few holes so blade fit in the middle, then the whole lot fits in the mastic gun lol do the same with a bit of wood the other end so end of tang doesnt push against the part of the gun what moves.
simple and easy and compress straight.
