I apologise if this is a basic question which should be obvious but i.m having an issue with building cannon and carriages. I think on a previous post I am attempting to build a model of the Black Pearl from which can be best described as a box of scrap wood purporting to be a model kit. To date i think i,ve probably spent as much on parts and materials as what the kit cost. Anyway moan over and the point of the post.In the kit are a set of cannons and laser cut carriage parts but no obvious trunnions.The cannon barrels have two minute holes but no instructions to either attach or fasten any form of trunnions. Any advice gratefully accepted
