Loose Joint Glue Ups (post #169651)

Hi -- I'm completing a piece that has 20 or so mortise and tenon joints.  Unfortunately, I messed up a few of them and they are fairly loose, I would say maybe 1/32nd of gap -- maybe a 1/16, though i really don't think they're that bad... anyway, i really don't want to refabricate those pieces... if i used a good gap-filling epoxy.. or even a type 1 pva glue -- would would happen?  many thanks.

That's too loose.

Glue some thin strips of wood onto the tenon to fatten it up and refit the joint.

Search the Internet for a general article on glues and gluing.  The ones I've read said almost no glue has strength in a gap.  Even with a glue strong in a gap, an open joint will not position the members exactly where you intended.  As Pete suggested, add some pieces of raw veneer as needed, sand/plane/rasp until the joint is friction tight, then glue.
