Here’s A Tenon I Hadn't Made Before.

While working on my latest project I needed to place the rails toward the inside of the frame.


This presented the problem of how to make the mortise and tenons. Since the uprights were only 1-3/16” x 1-3/16” by 11” high one of the tenons would be short.

This is the solution I came up with.
I made the longer rail tenons a full 1/2” long by 3/8” thick.

I then cut the shorter side rails tenons the same size but with a 1/4” x 3/16” rabbit on their ends.

Since these joints will require minimal load-bearing I think they’ll work in this application.

This added more glue surface than just cutting the tenons shorter.

I got great glue squeeze out when I clamped up the pieces.

Have any of you LJ’s had to make this type of mortise and tenons before?

And how did they hold up?

Here I’m gluing on a ledge for the leaded glass to rest on.

Thanks for visiting.
Best Regards,

Well you have come up with a solution. I have seen tenon’s close like in the diagram, and there was a 45* cut on the tenon’s so both would fit into the opposing mortise. I think you idea is better with the fact there is more gluing surface. Good Job.

I also did the same thing with a 45 on the tenon ends.

Your idea is more “interlocked” and should work excellent 8^)

Ditto on the 45 degree angle. Your solution should work fine.

Thanks for your input: Eric, Splinter and Jim.

The 45* angle is also a good way to make the close tenons.

Alternatively, I’ve also cut one tenon short (usually the side rail) and butted it into the other one.

It looks great. I don’t see any rebates. Are you going to use moulding to set the glass?

Do you mean a rabbit on the up rights? I’m going to just butt the glass up against the frame on the sides and rest the bottom on these ledges I installed on the bottom.
Here I’m using a piece of wood as an example.

I may have to widen the ledges to accommodate the bottom glass but foil may be the answer.
I’ll attach them at the top with these.

I going to try making the glass with foil instead of came so it will be lighter.

I’ll be able to change the bulbs from the top.

We’ll see what happens. I’ll figure something out. I hope. :^)

How did you do it?

Dang James, either that clamp you made is the size of a flea or you use a crew operated a pit saw in your shop 8^)

Are you planning to go full EarlS on your glass design? Gonna be a great looking fixture!

Thanks Splinter.
Funny you should ask. I was just commenting on Earl’s great clock build and saw you there.

They do look small in that photo but they are about 7/8” long.

Yup. I’m going to get as Early as I can. :^)

Looking good James, I was just commenting to Dave P, about that kind of clamp to secure a table top, allowing for movement. On the note, you may want to use clamps like that along the bottom to hold the glass in.

Super cool joints, will they be pinned, or just glued?
Look forward to see where this ends.

Thanks Mads. I’m just gluing the joints. I filled the joints with glue and when clamping it together got good glue squeeze out.

Cleaning up the glue is much better than worrying about joint failure.

So the square hole I see is for a plug, not for construction.
I thought you might pin through that.
Guess the glues these days are so strong, that it does not matter anymore.
