O.K. So, here’s the deal. I share my workshop with 2 cars (I know, It’s a shame, but that’s the reality.) So I needed a way to move my stock lumber and plywood around. Anyhow…
I’ve been trying to find ideas for my lumber storage. I had seen s couple of different plans in magazines but they just didn’t seem to be what I needed. So, as usual, I sketched up a couple of ideas and this is what I came up with.
The materials used were 2×4, 2×3 and 3/4”ply. Everything was screwed together and all edges were rounded with a 1/4” round over router bit. The total width is 30”.
I’m guessing that the cart weighs 150lb or so empty and fully loaded in excess of 500lb.
I started with (6) – 3” casters (rated at 150lb ea) which promptly failed from the weight, and I couldn’t even budge the cart loaded. (The picts show the cart with the 3” casters)
I then put on (6) – 4” casters (rated at 180lb ea) which helped a little… now I could barely move it with help from my wife (she’s such a trooper), but there’s no way I’d ever be able to move it alone.
Then I put on (4) – 5” casters (rated at 255lb ea). Now, I can move it fully loaded (but it’s a chore!!)
I’m no engineer, but I think that having 6 casters was creating too much surface friction. By increasing the wheel diameter and reducing the casters from 6 to 4 just seemed to work better. I should probably put on (4) – 6” casters but the cost is a little prohibitive. So for now, I think it’ll be fine.
