hey all

what’s the standard size for a tenon? if using 3/5 stock would the tenon be 1/4 thick?

or should it be thicker than that?

and what is the rule for the depth of the tenon?

thanks

The general rule is 1/3 of the thickness of the stock.

I go along with the 1/3 the thickness of the tenoned workpiece rule. Unless I am mortising into a thick leg, then I have the freedom to make the tenon a little bigger.
Remember it is not just the size of the tenon that gives a M&T joint its strength, but also the shoulders which help resist racking forces.

humm…from what I understand the longer tenon would offer the best glue surface so it would make for stronger joint (in tension at least) but if the joint is being worked side to side then I would think the thicker tenon would be beneficial as it would offer more lateral strength.. .
that would be my guess… .wonder what others have to say about it
