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
