New member here, been quietly reading up on do's and don'ts, but this thread caught my interest.
Though it appears the OP hasn't been back since their last comment, I thought I'd add my idea to the mix.
If you make(made) a tripod stand, here's an idea for putting removable casters on it. (Technically would work for a 4 legged stand too
Mount a short horizontal shaft (1/2"-3/4" diameter) to two decent sized fixed casters, and one locking swivel. (Locking swivel, not swivel with brakes)
the shaft needs to be parallel to wheel's axle, forward of fore/aft center line.
The shaft needs to extend to opposite sides of the two fixed casters (one right, the other left) Either side for the swivel caster.
On all three shafts, add a 1/4" hex socket head cap screw to the side of the shaft at the end furthest from caster, to act as a locking key.
The shaft needs to be long enough to allow the socket head screw to pass through the C channel sides.
Just forward of the shaft, mount a square(or hex) socket in the same plane as the shaft, but flush with the opposite side of the caster.
Now add a piece of C channel with a keyhole (drill, then add narrow slot with file) through the parallel sides, mount them to to the three legs with the holes through the C channel parallel to ground, but perpendicular to fore/aft to accept the short shaft on the casters. The keyway needs to be lined up so the caster assemblies can slide in/out when anvil stand is on the ground
you'll want to set their height so when the caster goes over center, the legs are high enough, to clear the ground. You'll also need to add pads to the three legs for the caster assemblies to rest on.
Using a lever with a square (or hex) stub sticking out the side (would look like a breaker bar with permanent cheater installed you can cam the casters under the anvil one at a time, as long as the casters only lift it up an inch or so, your center of gravity won't shift much at all. (If you're concerned about it, rotating the socket 90° would allow you to make the lever T shaped on one end to allow both fixed casters to be lifted at once)
