Hi All,
Just wanted to share this fun little project.
I built this as a wedding gift for my friends. It was built in great haste in the afternoons and evenings after my regular work

One of the funnest, most rewarding things about this was learning how to turn offset tapered legs with pad feet. There are two center points on each end, mathematically spaced to have the “node” (the part where the turning begins) spin true. So most of the leg is turned on the diagonally opposite offset points, pretty much only the foot is turned on true centers.

Species is Sapele legs/apron with Birdseye Maple top. I played around with the corner detail on MDF scraps until it looked right, then used that as a template to jigsaw it out.
Lots of time spent sanding the top. I found the BEM very challenging to work with and couldn’t get a clean line off the jointer.

Finish is tung oil and wipe-on poly.

Simple mortise and tenon construction at the apron to leg joint. Top is attached with figure 8s.

Thanks for looking.

inspiring post. I have 8 table legs finally mortised with router, and now I know what to do with the bottom half of the legs. Thanks for posting. Wish I had that LONG chisel rest.

Nice legs – can you share the equation for calculating the offsets?

Thanks for the comments guys.
JamesVavra: Sorry to take so long. Here is the source I used for the offset calculations.
It’s a good article, but I was confused by a few things, namely the seemingly arbitrary ankle diameter he defines.
I used the same 3/4”. Not sure what would happen if you changed it.

Good luck!

Thanks for the link – it looks like the distance between the outside of the top and the offset center make the maximum radius of the ankle. You could turn the ankle smaller, but it can’t be bigger.

Have your say...
