Is it better to drill the drain hole and then seal it with epoxy and redrill it to fit the plug...

...or would it be better to drill the hole a bit oversize, seal the inner surface with epoxy and then come back later, bed a copper pipe of appropriate interior dimensions in 5200 and flare both ends to prevent shifting?

I was going to use the first plan, but I've seen the second a lot on Bateau.

I went with an epoxy-glass tube, bedded and glassed in place.
I have the tool necessary to flare the bronze fitting, but the glass tube
worked out well. 5 years of use and no problems.

I did the same as Brett except I did not bother with the sleeve. Drilled the hole, filled the hole and then redrilled.

I did the same as Brett, but used a wood dowel covered in wax paper instead of a socket.
