I rarely have a large amount of sheet goods, and when I do it tends to sit around for a limited time. Given that I really don’t want to waste space in my very small shop, so I’ve decided that my wood storage cart should have slide-out base. This is a little difficult to describe clearly so, here’s the picture of the result both closed:
This allows me to squeeze this down to just under 24” with only a couple of sheets stored. It can be pulled out an extra 10”-12” to allow storage of larger quantities of sheet goods. It should be possible to put maybe ten full sheets of 3/4 ply on it (the three wheels on that side are rated at up to 350 lbs each).
The changes are only in the base of the cart, but they require a bit more effort than the rest of the cart. The support ribs are radiused at about 60” and were cut down from 2×4s:
You can see the rib’s thin interior cutout, which is useful for a number of things. Two are used in the router jig that was used to create the plywood cutouts (as seen above), and in the end each was used (after being cut down a little more) to fill a small gap between the plywood and each rib. It’s probably possible to make the ribs simpler, but the curved ribs allow a lower profile.
There are still some interior shelves to finish and then the tool storage on the top (hinted at in the diagram from before). Once I get that finished I’ll submit the finished results and possibly even a 3d model so others can better see the internals. For now here’s the partially completed and stuffed to the gills cart:
