getting perfect joints by filling gaps?
I am building a guitar and in some areas I want the best possible fit between two parts of wood to wood or wood to metal.
Working with a straight edge and being carefull I am able to get stuff to fit pretty nicely but tiny gaps like 0.02mm-0.6mm can be very difficult to fix by sanding, especially in areas where there are slight curves and angles.
I could glue it, but in some cases I do not want the two surfaces to stick to eachter as they are screwed fast, and i want to be able to remove the part easily.
So i want something that becomes hard and sticks to the wood, but not the metal plate. Like some glue I could get in between the cracks when the two parts are joined together, and then when it hardens not having the two part stick to eachother.
I was thinking maybe using something like hide glue, spray something like bicycle oil on the metal part then clamp the two pieces together and wait for the hide glue to stiffen then remove the part. However I do not know how hard hide glue gets, or if its suited for this purpose.
