SOJ, I can't add much to all the great comments, just a fantastic job you did there.
I quickly skimmed through the thread and saw pics you added with what contents you put into the storage boxes.
I have a few question for you. I have lots of nuts and bolts, screws, washer nails...etc. each box would be on the heavy side
Looking at you storage boxes that are at least 70% full of metal fasteners or similar, and assuming these are the heaviest boxes,, how would the rack hold up if all boxes were at least 70% full and reasonably heavy?
I don't think that 70% of my boxes are what I consider heavy, but I have had no problem with the drawer slides or any part of the wooden cabinet.
- Consider when moving the whole rack around, would the casters hold up?
The casters I used are really too light duty for the weight, they are just some I had on hand. I plan to replace them with some more heavy duty.
- Being tall and narrow, even with beefier castors, would it be prone to tipping if the slightest thing impedes a castor?
I share your concern with the height making it easy to tip over. I have tried to put heaver items (nuts & bolts) in the bottom drawers, and lighter stuff (pop rivets, wire terminals, fuses, hose clamps) in the top.
- Being tall and narrow and loaded with many heavier boxes, would the frame shimmy?
The cabinet frame will rack a bit if pushed from the front (open) side, at the top. The back, which is closed in with a piece of 1/4" plywood is stiff and solid.
You have inspired many and I would like to make something similar, just wanting to know if many heavy boxes might be a problem. Tall and narrow has a smaller footprint, which suits me perfect, but maybe half the height and more columns, like the workbench height idea might be better in this case?
The one thing I would change (if I built another one) would be to make it the base of a workbench. That would eliminate any problem with the height.
Besides a potential to tip, it is difficult to see in the top drawers, and I am 6' 1".
From your experience and answers, I can decide how best to proceed for my needs, thanks
