This has been in the plans since before I leveled the dirt for the shop. Finally getting to it. I had planned to make it out of nicer stuff but, I need it done and had some usable ply available. Enough excuses . . . we're off.
This is the general idea although the SketchUp file has been tweaked for so long that reality will probably vary a bit.

It swings on a single vertical dowel so as to stand parallel to the wall or perpendicular to it and anywhere in between to allow loading and unloading of material.
The base is a bit of a torsion box since this and the spine will take the brunt of the work when the fixture is being pivoted.

Here's a good shot of the "quality" material that will be used for the sides.

For the pivot blocks that make up the "hinge" I am using some cabinet grade birch ply. Other structural stress parts will also be made up of this material.

Large chamfers on ply have a tenancy to tearout along the veneer so I slice the top layer prior to milling the profile.

This gives me a good clean cut across the grain.

I imagine most of you know this trick to find out your caster's accurate height under load but . . . just in case . . .

The pivot blocks will be held to the spine partially by these barrel nut / bolt setups that were left over from my twin vise. For the vise they are intended to fasten your rear chop to your bench. My bench was designed with the vises in mind so the rear chops are built in. Therefor, extra hardware
:)

The parts are large and somewhat clumsy. Stacking things up to set parts on at a specific height can be done by scrounging random stuff around the shop.

Now I can clamp the pivot block precisely and drill for the hardware.

The barrel bolts seem to be more than enough by themselves but I added some SPAX-like powerhead screws anyway.

The wall mounted half of the pivot / hinge will use different hardware. I was going to go with the barrel nuts / bolts but I think it will be easier on me to adjust the position with some 1/4" SPAX fasteners instead. Time will tell if this was a bad decision or not
:rolleyes:

I want some large rabbets running along the top and bottom of this panel.

The DRO on the tablesaw comes in handy for this type of joinery.

This jig is used as a tall router table fence, a tall tablesaw fence and with a couple additional doo-dads, a panel traveler for cuts just like this.

Here's the desired result.

The wall mounted pivot blocks will go something like this. The exact vertical position of the fixture and the horizontal position of the "ears" will be determined . . .
hopefully tomorrow
<_<

This gives you a general idea of the mechanism although the vertical dowel is not present in this shot.

I was going to use tempered hardboard for the "floor" of the corral fixture. I then remembered that I had some leftover FRP paneling from when I made my cyclone barrel sleeve. I find a guided circ-saw more pleasant to cut this stuff with than guiding it over the tablesaw.

The FRP has an odd end so I scribe it to fit; first a pencil mark, then a razor knife. Once scored you can snap this stuff with pliers for small ends or like drywall for center of large panel cuts.

The casters on this rig will be fixed. They will be positioned along the radii of the pivot point (the dowel). This is easy to plot with a string and a pencil. The arc close to the pivot is somewhat tight.

The arc at the end farthest from the pivot is a lot more open.

I mark the center of the caster at the front and rear.

770913771_McLarenPlywoodRack(25).jpg.78992b85bad47a109e2977f898e90cde.jpg
I line these marks up with the arcs I just plotted, mark the plate holes, drill them and fasten the casters in place.

Although I have glued and screwed the sides into place I am almost done for the day so I clamped the pee-wad out of it as well.

I'll pick it up in the morning and with any luck, have sheet goods loaded into it before the end of the day.
 
Well I got it mounted and threw a few sheet goods that were laying around the shop into to test it out. I'll gather the ply and such that is scattered around the storage sheds tomorrow. Here's the two main positions as described.

A couple shots of the hinge parts.

The design includes a lifting ring on each side that let me pull and push the rig from the torsion box bottom. There is a piece of 3/8" all thread through a solid member at the front of the base assembly.

And that is pretty much it. I will enjoy having somewhere for my sheet goods to go other than leaning against the walls where I have to move them around or out in the sheds where I am not even sure of what I have.

I wanted to do something besides work on shop fixtures so I just gathered a lot of the sheet good shorts and stashed them where I plan to build a rack for such things.

I also gathered a lot of full and larger pieces of sheet goods from where they have been stashed for a couple of years here and there. I still have room for a few sheets of 3/4" and the rig moves back and forth easily.

I'm pretty happy about that ;-)
