I just now found this thread, but since we got our barn floor poured cured, and sealed, I have been making implement (and compressor, and wood rack, and tool stand) dollies from pallets and scrap wood using casters sourced variously from other rolling fixtures, garage and barn sales, a hospital dumpster (I really miss the swag from that job), HF, Northern Tool, TSC, MCM, Grainger, and whereever else I can source decent quality casters for as cheaply as possible.
So far all have worked well, because I am careful to index the capacity of the casters to the approximate weight of the item to be stored on it.
There is one case how ever that I did not do a good job of matchimg the casters to the item, and that is actually one of the smallest pallets I used (an approximately 2'x2' square), under which I used the same casters (rated at 150# each) that I also used under the 5'x 2.5' pallet/platform we put our 4' Gannon ROBB on, which rolls easily.
Have you guessed what small, yet dense and heavy implement I underestimated the weight of yet?
It is the "Kubota-branded" ballast box we loaded with steel disk brake drums and other scrap metal and concrete, hoping to get it to a weight of something a little over #500 because that is what the label on it recommended. Apprently we over shot that at least a bit
I have some bigger casters from one of the more industrial sources, and I will be making a new small platform cart for the BB.
The one implement (or probably more accurately attachment) that we won't be storing this way is the 60" MMM, because it seems like it would be more efficient to store it on edge, whether vertically or horizontally.
The 3-point boom, being very sturdy, durable, non-mechanical, non-hydraulic and already rusty because we bought it used, will be ignominiously stored outside in the weather.
