A subtle yet very effective finish applied to one of our best selling stools. This one ebonised using rusty vinegar solution sprayed on. Sanded back and finished in three coats of mineral oil. Stunning!

White oak posts? Or some other kind of wood? Nice use of shadow lines in the saw kerfs (?) where the posts meet.

It looks to me like it’s four individual pieces glued up and minimally carved to look roughly like a backenzahn or rear tooth MOlar,lOL Alistair

Start with 6” rough sawn stock. Have done these in green oak, but better when 3 year air dried or better still (££££) Kiln dried.

PAR. crosscut to +10mm finished height x 4 (legs)
I have made a jig that allows me to use the tablesaw to cut angles in legs. You now have 4 identical legs.

Each leg is marked for a 25mm oak dowel to sink 50mm into each flat/mating face. This has to be absolutely precise. NO margin for error to within .25mm. If you are out… may as well start again! This is not a “I can sand/plane that at the end” kind of piece.

Oak dowels in, glue mating faces using titebond of course. Clamp in all directions overnight ensuring good 90 degree angles and a flat top (ignore squeeze out).

Remove clamps.

Sand rough 40 grit with belt sander top and sides. Clean any squeeze out underside using a sharp chisel.

Ensuring top is perfectly flat, set up fence on tablesaw and saw height to 10mm to run a recess through top in both directions centrally. Then vertically through legs.

Using a clear malt vinegar solution that has been eating rusty steel for 2 weeks (strained) and spray the entire piece until it is soaking. Allow to dry overnight.

Piece will now be BLACK

Sand all faces using 40 grit, working to 180.

Crosscut bottom of feet using sled on tablesaw.

Hand sand all edges/corner.
