Just a drop in each hole. You really wont need much. Get two stacks of 8 playing cards either side of the axle and set a flat heavy object evenly on the top of it. Make sure it is on a hard flat surface too.
With properly mixed and applied epoxy, it won’t come apart ever again.
I don’t know if that applies to epoxy as it does wood glue. I made the mistake of using some old wood glue. Didn’t even hold 10 minutes. Fresh was the way to go.
it’s crazy how different wood is from any material, such a nice soothing feel to it.
Edit: after picking up my Harbinger to check the grain i have a very strong urge to throw it again.
Glen the end of the axle looks to have cuts in it (intentional cuts), should in try to get the glue in the cuts to help it stay better or just the hole?
