They may take time, but it’s tough to beat the good old M&T

Check out the Jessem dowel jigs.

Dowel rod sold in hardware stores is not very
round. I’d recommend many 3/8” fluted dowels
over a few 1” sections of dowel rod.

I recently saw a video by Matthias Wandel (inventor of the Pantorouter) where he was testing the strength of three different joints on a face frame. On a right angle joint with the two pieces about 12” long he tested Kreg type pocket hole joints, multi dowel joints and mortise and tenon. He did 3 samples of each. The screw joints withstood about 100 pounds of pressure, the dowels about 160, the tenons about 200. Also on the tenons he did three different types of glue. Yellow glue, Tightbond III, and epoxy. The epoxy was the strongest, breaking at about 220 pounds. For this test he did not glue the pocket hole so later he retested them with glue and there was almost no difference.

Obviously there is a difference in the amount of work needed to produce each of these joints but it does give a good reference to use for deciding what type of joints you need for a particular project.

I’ve used all the methods mentioned, and never had a failure with any of them. Dowels will work if you prep the surfaces well. I’d also put a wash coat of glue on the end grains of the aprons. Keeps the final glue from soaking into the end grain.
Just my thoughts.

Joecarrr, you’ve been lurking? You’re one of 243,000 finally accounted for. Now, I just need to find the other 242,999 lurkers.

Thanks for the replies! Loren, why would the 3/8 dowels be stronger than larger dowels?
Good tip on the end grain bill. Thanks!

Well, regular fluted 3/8” dowels are rounder
than dowel rod but I also think you’ll get more
long-grain glue surface using a bunch of smaller
dowels.

Have your say...
