Appologies to the original thread poster, oldno3fan. I probably should have posted this info/pics on a separate thread.
That is a neat idea for a top tier. How sturdy is the top section? How is the top attatched to it, from underneth with small screws? I might have to use that idea on my bench.
The supports are pretty sturdy once everything is tightened down. I only had half of the screws in the back three legs tightend when I did a "sturdy" check and the shelf wouldn't budge. I staggered one of the four legs, it is mounted ahead of the other three, underneath the shelf as it curves on the right hand side. It's a VERY sturdy shelf once all the screws are tightened.
The stainless seems a little soft and the supports don't seem to be 100% square - but they're acceptable for $15 per pair. The bottom of the leg has a single largeish bolt that goes through the countertop. At the top of the leg is a square flange that is made for four screws. The screws are really cheap and a striped a half of the first eight I installed. I ran down to the hardware store and got quality screws with a head that would work with a 1/4 inch socket. The new screws made it much easier to tighten everything down.
Here's the finished product. Now I just need to find another block grinder to mount above the current grinder.
