No glue.

Long story short – no glue joint…pretty cool.

If I ever do find the need to use dowels for joinery, with this joint I know it will last with no chance of glue failure. I don’t know if you invented it but I’ve never seen a double wedged dowel like this. It looks like it would work just as well with a loose tenon wouldn’t it? Thanks for sharing.

although i havent used them yet, i like the idea of using dowels for joinery – especially for drawers instead of dovetails. the issue with dowels is really in the different rates of wood movement for each grain orientation when joining crossing grains. i think there’s an old article in FWW that describes this.

anyway, this seems to be a good solution. how did you wedge the hidden end?

this is sort of like the tenon lok system, but smaller and double-sided. nice!

Split the hidden end of the dowel with a chisel, partially insert the hidden wedge, drop it into the hole and drive it home. Then split the show end, insert wedge and go crazy with your favorite hammer.

i think the right use of dowels can make a beautiful piece of work. one suggestion is to drill a small relief hole in the dowel and then saw from the show end to the hole. you can use a thin kerf bandsaw or a flush cut hand saw. at least that’s how a typical wedge tendon works. one other item. if the wood dries out any at all, the wedge will loosen. a stop of glue will cure that.
