One other consideration is lateral bracing. It’s going to take considerable force applied to the top of the island to get 500 pounds moving. In your picture, should be fine front to back. But if you push from the left or right there isn’t any lateral bracing, so that will put a lot of pressure on the hardware used to connect the vertical elements to the top and bottom and it could end up sagging to one side. I’ve seen that happen with a friend’s small stationary wine rack.
One solution would be to put a shelving/bin section in the middle portion of the rack with a middle divider (i.e., each bin would have sides and a back). That’s how my island is constructed and it’s very sturdy (but not on casters).
Do you mind me asking how much this ended up costing? I am looking into building a house end of this year/beginning of next and would like to build a small cellar room in the basement.
It’s been a while since I posted an update on the wine cellar project. Current status is that I’m trying to finish up the insulated door. I filled my door frame with foam board insulation, added a skin of 1/4″ plywood, and then added trim for appearance. The result is a 5 inch thick door, insulated to R-21, that looks like all the other old doors in house. Next step: Hinges.
okey dokey. Floating storage island came out pretty good and is pretty stable- a two person job (or need to build a good ramp) o get smoothly over the door threshold, but main point of wheels is to shift it around to maximize storage and be able to access everything.
Hoping to never have to post on the breakage thread.
