A trick I figured out long ago for repairing checkering or fixing screw-up in new patterns. I Never use superglue nor epoxy. I mix walnut dust, (saved from cleaning up the electric cutter dust) and mix with Duco Cement. Duco is a very strong, rubberized type of glue not unlike rubber cement. It dries fast, hard and unlike epoxy or cryo is not shiny. It can be stained and recheckered almost like real wood.
I get it at Ace hardware. My Dad used Duco Cement for his wood model train car kits, scenery and just about everything else.
