Originally posted by nontypical: SveinD, the epoxied dowell will not let the insert push back against the shaft,aiding in it not splitting.What I do is put epoxy up inside,I then coat the dowell also,I then push up and leave .125 of dowell out,coat insert,then wit insert push the dowell the rest of the way in.Now they are tight,back to back,leaving NO space for movement.
