When preparing for our Gorkamorka campaign we ran into a minor issue - modern 40K orks don't have kannons or six-shootas. There's other weapons like crossbows too, but those two were the biggies.
I have some old GM kannons, but they look positively weedy in the hands of a modern ork boy. I'm wondering how others get around this issue?
My personal solution was to sculpt my own kannon and cast it in resin:
I think my second attempt has gone significantly better, my resin pouring skills are still lacking, but I feel the mould came out much better on this six-shoota. Hopefully you guys will like it:
