I’m working on a small wooden box project. See attached pics.
The box is built. Everything fits together nicely. Very snug fit where the lid meets the inner rails. That’s how I want it to fit. But…
I know I need to allow for the finish. Having never made something that fits like this, I don’t know how much I should allow for the finish, yet it’ll still fit snug once complete.
The inner rails hold the lid square and in place so it’s important that they fit just snug.
At the same time, I don’t want it rubbing off the finish or marring it badly taking it on and off.
Right now my thought is to go with 3 coats plus sealer of oil poly for the interior section including the exposed edging.
Though that may change as I’m also considering going with lacquer for both exterior and interior or visa versa.
Everyone talks about how to finish but I’m finding nothing on how much space should be allowed for two mating finished surfaces using lacquer or poly.
Obviously, now is the time to sand that allowance into the rail. I’m also thinking of adding a slight chamfer to the rails to ease it when putting the lid on.
So how much space is needed? I can’t remove anything from the plywood sides so it all has to come off the rails.
