I’m building a cherry bench with slab top and slab legs. I’m using dowels to join the top to the legs and stretcher to the legs. The dowels are a bot loose in the holes. Will glue be strong enough or should I use epoxy. This is my first piece to sell so I want it to be good and sturdy. Thanks.

If the dowels are loose, switch to bigger dowels. Sure you could use a liquid that expands to hope the gaps are filled, but wouldn’t you feel better knowing you sold a piece where the joints were tight to begin with?

An epoxy would probably be best because of the loose fit. Otherwise use a gap filling/expanding glue like gorilla glue.

Use wedges in the dowels to tighten the fit. It is always better to have a strong mechanical bond than to rely on glue to compensate for a weak one.

Wow. Thanks for the quick replies. I should clarify – used 3/4” dowels and 3/4” forstner bit. The dowels wouldn’t fit so I had to sand a bit. Not horribly loose but I wanted to create room for the glue/epoxy.

Or wedge the dowel.

Dowel rod sold in hardware stores isn’t round.

If you’re getting your dowels from that material
I recommend re-thinking the approach.

Round dowel stock can be made with a jig on
the table saw or with a router table.

Well if you sanded them too thin, can’t you just get new ones? :)

Otherwise, I agree with the wedged approach too.

Sure. I have some of the rod left. Don’t I need some room for adhesive in the hole?

How loose are they? If there are no big gaps and the dowel holds on its own, just use some PVA glue.

If you have an 1/8”+ thick pc of steel you can make a dowel plate.

Drill a hole. Pound it through. I did some 1/8” dowels recently. Worked like a champ.

Many dowels that are made for the purpose of joinery are fluted so that the glue has a place to go when you pound them in. If there is no place for the glue to go the dowel will not go in all the way. If I were making my own dowels I would take a triangular file and make some small random notches on them for the glue to go.
