I owned a timber furniture business for many years using timber slabs up to 4 inches thick to make very solid tables and benches, mainly for public use. However I also had lots of customers wanted dining tables made out of timber slabs. Not being a trained wood worker I used to love preparing the table top but had all sorts of difficulty getting the legs right. Either the slab wasn’t milled strait or it warped as it dried, or just ensuring the heavy table didn’t wobble, there was always a problem.
After I sold the business I decided to solve that problem by designing cast aluminum table legs with height adjustable feet and a large fixing surface that just screwed onto the underside of the slab. It’s a pretty limited market, but for people with access to timber slabs, these legs are just the thing for quickly whipping up a solid and unique table.
