Drawboring! I learned the hard way what happens if your offset is too far off. So here's what I learned the hard way: Even if you can dry-fit and get your drawpins in each joint INDIVIDUALLY, that doesn't mean your alignment will be exactly the same when you assemble MULTIPLE joints and pressure is exerted in different ways. In this case, after I successfully pinned the first joint, the next joint moved far enough that I was unable to fit my drawbore pin. And faced with a glued up peg, I didn't really have much recourse. I tried hammering it in anyway and this was the result.

I didn't know how to fix these issues other than starting over from scratch, so of the 8 drawbored joints in the base of the bench, I broke pegs off in 3 of them. Lesson: Make sure your drawbore pins fit before hammering in the peg. If they fit dry but then don't fit when you've changed something, don't force it. It'll just break. Other option is just pegging the joint. You won't get that mechanical grip but if you force it you still won't get it and your pegs will just break.
