Hey guys. I have been building a wine table. A wine rack under a concrete tabletop. The table is not large (i think its only about 24” tall and is being held together by 24 mortise and tenon joints.

In the past if a project is m&t, and is being used as a seat or was going to be under any physical stresses i typically pinned the joints. I am wondering how many of you would pin the joints on a stationary item that would not be abused in any way such as a wine table…

I hope this made sense as the whole time my wife was asking me questions and i am not a multitasker…..

Will it have to support the concrete top? A picture goes a long way toward getting useful answers on this type of topic. Very difficult to conceive the problem given your description.

I like pins and feel they lend an older feel to the project. Obviously the pins in the half lap joint offers a backup if the glue fails, but with today’s glues that is not an issue. In the second image I pinned the face frame on a door holding cabinet.

PLUS, if you want to leave them a bit proud, they can add a real customization look to the piece. Just my 2-cents…

Sorry that the description is vague…i will include some pictures on this post.

The table base is 22” height x 16” wide x 12” deep. There will be a concrete top on this table with the dimensions 18” wide x 14” deep x 2” thick. It is made of solid hard maple with a lacewood inlay on the front.

Every joint in the project is mortise and tenon. Thusfar they are not pinned.

Thanks in advance for any suggestions or comments.

Personally I would leave it like it is. I love drawbore pegs and when used in the right style of furniture they add a lot to the appearance. However I think they would actually detract from the clean sharp detail already built into this nice looking piece. Lateral movement won’t be stressing the joints so there is really nothing to gain structurally from adding them as well.

Thanks. That is exactly my fear in doing any pinning on this is the aesthetic aspect. I am concerned that it might pull the eye to areas that i wasn’t intending to be focal points.

Thanks for your input

I agree with the above comment. Your design and execution is so clean, the pins would just add “clutter”.

I agree, I think the pins are unnecessary are far as strength goes. Those legs are plenty sturdy. I think adding the pegs would really clutter up your design which is quite pleasing as is.

Well, if three is a charm, you got it. I agree with manta and gfadvm above, pins would not go well with the trim on the legs, which by the way look super. And, as per manta, since the table won’t be moved, all stress will be straight down, and pegs won’t help with that. All you need to worry about is the compression limits of the maple legs.
Nice job on this build, looks great.

Let’s make that a grand slam. IMO, leave it as is. It looks fine and indeed, too modern for pins to look good.
