This is a little “mini-tutorial” about the technique of draw-boring. This technique uses dowels to reinforce mortise & tenon joinery. The only difference is, the holes in the tenon are “bored” slightly offset, so the tenon is “drawn” into the mortise as you drive the dowel into place (hence the name).

I used this on the workbench trestle bases that I made for Woodguy1975, and also for my own workbench project.
