Topic tags/keywords: table top wedge peg question ash finishing joining arts and crafts shaker

Building an Ash Cabinet with 2’X4’ top. I’d like to attach legs to top with no aprons to attach to. Thinking of cutting legs into top as through tenons similar to porch swing pictured here.

Will there be expansion issues? Is there another option attaching tops directly to the top of a leg?

Also, to tighten, in addition to glue, I’m considering a wedge tapped and glued into top of legs. Do I have to consider grain direction when cutting a wedge kerf?

Finally, taking comments regarding finish on ash.

- Thanks

i would think the expansion wouldn’t be a problem since there is no apron that would have a grain direction perpendicular to the table top.

When cutting a kerf for the wedge, I don’t think it will matter which way it goes in the leg, however you will want the wedge’s width (not thickness) perpendicular to the grain of the top piece. That way, as you drive the wedge in, it will try to stretch in the direction of the grain rather than trying to plit the grain apart.

As far as finishing goes, I like the natural color of wood, so I would use a few coats of Satin polyurethane

Good Luck!

Other things to be aware of when you position your legs in the table. The end grain of your legs, being through tenons, will contrast if you want them to or must be properly prepped if you don’t want. If your legs are quarter sawn, expansion of your leg will be very minor so you get to decide if you want the end grain to be perpendicular or align with the table top. If you have plainsawn wood in the leg, recall that though minor, the legs will expand across its grain so the end grain of the leg must be perpendicular to the long grain of the table. Lastly, if you have grain that runs across the top of the leg diagonally , align your legs so that the grain would form an X to the opposite corner to provide the most stable joint in relation to the grains.
Good luck with your project.
