Squizzy,
mitred externals and coped internals is how it's generally done, accepted industry norm. Having said that I used to fit panelling and mouldings to all the boats made by one particular company and we (compound) mitred everything. Most joints were at anything other than 90 or 45. The bloke I got the work through and worked with for the first few years was a pattern maker by trade. He used to eyeball the joint, ocasionally drawing the positions of the mouldings on the panelling for the tricky bits, sometimes three dissimilar mouldings meeting, sometimes a curved moulding marrying into a straight one, etc. After eyeballing it he would cut it with a jigsaw and then clean it up with a (razor sharp) low angle block plane and sometimes pare it here and there with a chisel. We used to lacquer all the moulding before fitting them and you couldn't fault the joints, you'd be flat out slipping a bit of cigarette paper in. But even the simpler joints would take about half an hour each as opposed to about five minutes for a coped joint (ten minutes for colonial type mouldings).
