Morning all. I’ve started he Gentleman’s dresser ( from Woodsmith). I’m a bit concerned with the tenon size for the panel construction. The drawing calls for a 3/8×3/8” tenon and associated mortise. While I’m no cabinet maker, that looks like a heart break in the making. Now that I’ve cut my material to length I’m kinda buggered. I going to remove those sickly looking things and go with floating tenons 3/8×3/4 long. Whatcha think?

Mark, I think the 3/8” will work just fine because of the total width.

Crazy, those will be plenty strong enough.

I agree that the tenon is big enough, but where you will get into trouble is if you glue its full length into the mortise. Perhaps the plans address this, but you want to apply glue to just the top 1/4 to 1/3 of the length of those tenons. If you glue its full length, the board will split eventually.

If your panels or plywood, you should worry about wood expansion. for gluing. If panels are solid wood then it matters where you put the glue. the size of your 3/8” tenons should be fine.
