While I am re-habbing my shoulders, I'm using a plethora of small dumbbells and kettlebells - and since my garage is small, I needed to be able to access them AND get them out of the way when not in use.
While cruising Pinterest for DIY storage ideas, I came across this page:

This was great - a Harbour Freight moving dolly, and a dumbbell rack from Marcy (Model DBR56) - along with a small piece of plywood and BAM! - you have a small rolling weight rack.
I thought I could improve on this great beginning - and this is what I ended up with.

The frame makes it easier to move the fully-loaded cart around, without having to bend over - as well as providing an anchor point for some tool clips to stabilize the handles of the macebells.
