Problem Reported missing legs
Fix n/a


Steve wrote in and asked for dimensions for making wooden legs. After an appalling delay, I took some pictures and measurements.

I have pile of mismatched legs. The primary differences are:

  • number and location of stress bolt holes
  • bevel vs. round-over on the leg edges

Leg Overview


The most common leg was 1-3/4 x 2-5/8 x 30-1/4" and I think made of oak with the grain running vertically. The edges on the front are rounded over, and the edges on the back are either rounded or beveled.

The top/front edge of the leg was rounded much more...looks like they did it by hand using a belt sander as the curvature varied.

Main Bolts Holes and Cabinet Notch

The main bolts are 3/8 x 3-1/2", 16 threads/inch acorn head. The holes for them are 2-3/4" and 5" from the top of the leg, and centered within the leg and notch. Verify the hole spacing to your cabinet!

A 9" long 45 degree/edge notch is milled into the back of the leg which the cabinet fits into. The bottom 1" of the notch is cut so the notch slopes out smoothly. I assume this was done by pulling the leg away from the router bit during the last 1" of cutting.

The notch is 7/16" deep.

Stress Bolts and Holes

Four bolts are used at the top of the legs to help prevent splitting. The bolts thread into a sleeve that is centered inside the leg (like a short segment of a drinking straw that is threaded inside).

The bolts are 1/4 x 1-1/4", 20 threads/inch, but whatever matches the sleeve is fine.

The holes for the stress bolts are 1-1/2" and 6" from the top of leg. 5/8" from the notched back of leg.
