Im building an entry bench and was wondering how wide and long the tenons should be. Heres the info:

Apron will be 3/4” x 7” x 40”
Legs 2” x 2”
Material is cypress
The bench will sit a max of 2 people at a time

I was thinking 4” wide and 1” deep? Whats everyone else think?

I think the 1” is good. Not an expert here but I think you might want the tenon closer to the edges to prevent the apron from twisting. 1/2” to 3/4” from top and bottom. Maybe do a double tenon, I’ve seen that before in wider situations. I’m sure some Jocks with experience will better explain why. Its a good looking design. Besure to post your progress.

I was planning on having a 1/4” reveal between the face of the stretcher and the face of the leg. I will start the mortise 2” below the base of the angle as seen in the pic, which should put the top of the seat just about flush with the base of the angle.

Thanks for the idea of a double tenon Dan … go ahead make it tricky for me lol. There will actually be 2 slats on the inside of the bench between the back and front apron which should keep it from twisting. I decided to put thos in there to bear the weight of the seats so all the weight isnt on the apron and make seperate compartments. Ill be using a glue up for the seats themselves reinforced with some 3/4” plywood underneath.

GO UCONN !!!

This all sounds pretty reasonable, chrisstef. The one inch is on the long side, but fine if your method of cutting the mortise keeps it true to that depth.

I’m not sure why the 3/4 ply reinforcing the seat. I would think a glueup on the structure you’re describing will be plenty strong.

You didn’t talk about the thickness of the tenon front to back. It’s on my mind because I cut 16 mortises today in 13/16 stock. They’re 5/16×7/8 deep. (Tenons will be 3/4 long.) That leaves a nice 1/4 shoulder to square to.

Onward! This will be a nifty bench. Cypress finished natural?

Lee,
I have them drawn up as 5/16” thick, my stock is 3/4”. I have 16 to do myself.

I thought about using the plywood due to the fact that the seats will end up being a 2 piece glue up and was worried about the strength of edge jointing 2 boards together which are intended to be sat on. I would have cleats inside the cubbies and the plywood would actually sit on the cleats instead of having the glue-up portion bear on the apron. The seats will be 19” wide.

Ill be using a drill press and a forstner bit to hog out the mortises. Finish with a chisel.

Im actually thinking about using a medium to dark General Finishes dye stain, and polyeverything for finish. The colors in the room right now are walls: pale yellow painted board and batten, very pale blue bead board ceiling, and off white trim and crown. But as we all know it has to pass the wife test for color.

Color sounds awesome. I like General Finishes products, especially their WB poly.

You don’t need the plywood. An edge to edge glue joint is stronger than the wood. As cool as this is going to be, plywood would be a letdown. Leave it leaning against the wall. ; )

If your tenons are well seated in the mortise on the bottom side, your apron will bear the weight of the sitters, no problem.

Will you be doing progress on this one in a blog?

Lee,

Sounds like ill let the plywood go, i agree that it would be a let down, i have a tendency to overbuild things. Maybe i will blog this one, that is if i can find some time to actually get in the shop. Thanks for your insight. I look forward to getting this one rolling. Hopefully my ideas dont overshadow my experience, but theres onlly one way to find out.
