|thelub||Thanks Hoppy. While not the answer we were really looking for, its something I guess.|

The slab walnut shelf was built and installed in my gallery space. Shortly thereafter it was sold to a client and installed in there residence. I can't complain about the sale but I'm left bare until I find time to process another slab.

|talontsiawd||Wow, that's pretty awesome. It's also funny how many people get concerned about 100lbs on a shelf. Seen much crazier/heavier things in my life and that shelf looks pretty solid.|

|thelub||I wonder if this ever came to fruition|

|lochaber||Yeah, that sounds a bit stronger then what I was imagining. I was thinking of a pipeflange just held in with some woodscrews.|

I think you have it strong enough, with adequate safety factor too. The through bolts, and the 4 x 4's plus having 5 of the pipes supporting the load convince me.
I don't think we are doubting Thomas's, we were just lacking the details.

Sounds like there are some doubting Thomas engineers following this thread.
I know nothing about this type of construction - I just think it's a drop-dead-gorgeous shelf, and I can't wait to see photos of the tank on it.
I looked for your build journal and couldn't find it. Do you have a direct link?

|Christof||The iron pipe supports are actually 1.5" and have an extremely high modulus of elasticity. The load (shelf weight plus 120lb tank) is uniformly distributed across 5 cantilever pipes spaced 16" OC, with a majority of the load being placed on the fixed side of the cantileaver. The pipe flanges are attached to 4x4's by way of through 5/16" carriage bolts. There is Drywall between the pipe flange and bearing wall with a compression strength of around 300-400psi. The weak link is actually the bearing wall but with double 2x4 framing structural failure is highly unlikely.|

|thelub||If you are running all the mechanicals in the other room, can you run tubing for the filtration through your support system? Seems like it would strengthen that shelf if one or two of the 1" pipes went all the way through the wall.|

|Hoppy||Can you put all of your weight on one of those pipes without it deflecting? If so, it is probably strong enough. I would hesitate about trusting a pipe flange for much structural support. I would worry about the screws either pulling through the flange at the top, or popping the heads off the screws.|

|lochaber||So, is it just pipes bolted onto the studs via pipe flanges? unless you have some direct floor-table vertical supports, or some sort of cantilevered support, I'd be real hesitant to put much over a couple gallons on it.|

|Christof||The slab is floated about 3/4" off the wall. It sits on top of a series of 1" black pipes which I attached to the wall with a pipe flange. The flange is screwed into the wall framing which I have installed sister studs from the backside for more strength. Make sense? I could have bored the pipes in the slab to conceal them but at 30" off the floor it's hard to see the pipes under the shelf.|
