Go for the 15-year. Best bourbon I’ve ever tasted.

I just want to know how the pappy’s taste.

So… what you’re saying is that size does matter.

Darn, us boutique (available, Iowa, Illinois, the coasts) are rye drinkers are out then. Consolation: I have a great source for white oak, and armed with a Lie Nielsen dowel plate…

Don’t have the math at my finger tips, but would suspect that stiffness is a cube function of the diameter.

And yes, there are definite rules as to peg size and its relation to placement on the tenon.

Would have to go hunting to find written references. It is a big deal in timberframe work.

At some point I’d be worried that the drawbore peg would be stronger than the short grain at the end of the tenon and would just split it out rather than bending through the offset.

Anyone had this happen in a bench-scale assembly?

You graciously left out the part where “Narayan” cut one of the leg tenons a smidge short then fixed it with a vat of “epoxy”.

Chris,

Do you have a rule of thumb for edge distances in drawbored joints? If you use a 5/8 dowel, what would be the distance from the edge of the hole to the edge of the board. And I guess the question is for both the tenon and the cheeks of the mortise.

Much tougher indeed. If y’all remember that the area of a circle is Pi x radius squared then that “little extra 1/8th of an inch diameter” increases the cross section by approximately 50%. Too bad that I didn’t think of this earlier: I finally got to assemble my Roubo about two weeks ago. I only exploded two pegs and was able to drive them through with new ones but the 5/8″ ones would have been a good idea. No worries, the bench is solid as a rock; a big rock. Loved the book by the way. It helped me build a fantastic bench.
