What kind of clearance is best for movable parts like a door against a bulkhead. If each piece is going to get 3 coats of
epoxy plus several coats of
varnish and or
paint you donn't want them to fit too tight.
I was thinking that a piece of 80 grit sandpaper would be a good thickness test.
So how may layers of 80 grit paper should fit in a joint so you know you have enough clearance?
I'll bet you guys who have built multiple boats know exactly how much room to give it.
