I'm trying to make some butterfly patches to prevent the checking on the end of a board of maple from going any further. I was able to cut out the shape with my router (not pretty but will work). I'm having some trouble making the insert. I was wondering...instead of trying to cut out an insert to match the hole perfectly can I use some type of epoxy or even wood glue? Would this prevent the split from going any further? This is all being done on a piece of 5/4x8 maple.
