Oops, I completely misunderstood your design. I thought it was all wood and didn't realize that it had metal legs and frames with wooden shelves fitting inside the metal frames. I'm building an all wood stand as this is a project for a woodworking class. So it looks like I won't be borrowing your design ideas for this stand.
This is how I thought Dave's design worked, all wood with shelves let into dados and rabbets (top shelf). I'll talk it over with my instructor but I'm inclined to use this design instead of my original idea. I'd glue it all together rather than bolting it though.
After seeing the price of these stands, I now don't feel so bad about how much money I have invested in the lumber I bought and had milled. If I do a decent job with the stand, I'll have quite the bargain.
Also, I need some reasonable level adjusters to use for feet. Does anybody have recommendations? The feet used on this Timbernation stand look interesting. Does anybody know what they are?
