I am making slooooow progress on my first workbench build. It is a roubo style bench made mostly of fir. I finished the tenons for the stretchers and started putting holes in the legs to drawbore the tenons when the bench is assembled. Another in a long list of stupid mistakes: I didn't research the best practices for drawboring BEFORE I started drilling holes. Most of the info I've found suggests putting the drawbore holes about 3/8" from the tenon shoulders, but I drilled holes in the legs either 1.5" or 2" from the shoulders, so that's going to put the drawbore pegs right in the middle of the tenons (the tenons are 4" wide by 2.5-3" long by 1/2" thick). I have NOT drilled the holes in the tenons yet, just through the mortises in the legs. Each of the holes is 1/2" thick to accept oak dowels, which I also now realize is a little on the large side for drawboring.
So my question is how to proceed from here, which I think really depends on just how likely it is that I will split the tenons when I drive the drawbore pegs through. It is not likely, then I will just proceed with the current holes and 1/2" pegs. If there is likely to be trouble, then I could potentially just re-drill new holes closer to the shoulder of the tenons and then just put a plug in each of the first holes to fill it up.
Thanks for any advice!
