Another thing about quick-n-dirty double layer MDF radius dishes is they aren't so precious that you can't use them as you want. For on-off projects I use throw away brace clamps made from 3/4" plywood and screwed directly to the work dish with 2" drywall screws.

I made a pair of radius dishes out of MDF using a router, what a mess. But I am happy to have them. No finish on them and they are still fine. I have tried other methods just for the heck of it just to see what would happen. Gluing a top and back that were arched just by the radius of the braces glued on them. Then glued onto rims that had a taper heel to butt but no compensation to account for an arched top. The rims edges and linings were sanded flat on a flat surface. All kinds of ways to build.

The Irving Sloane method was to position a "sanding stick” with a pivot hole about in the center of the guitar slightly raised from the finished height of the sides and spin it around it around the sides, neck heel and tail block.

Re radius dishes
The cheap way is to mark out some pieces of pine to the desired radius and glue them down Alternatively get someone local to make one up for you That has a cnc machine These are the ones I make for myself in house

1: I wrapped 80 grit sandpaper around each "wing" of the sanding bar and opted to staple it, but there are probably better ways to keep it put while sanding. 2: drilled a hole through my work table, 3: ran a threaded rod about 8" or so long through the hole, 4: threaded a nut/fender washer with a locking washer underneath the table 5: put another nut/locking washer/fender washer on top of the table to stabilize the threaded rod, 6: drill a hole all the way through the center of the sanding beam 7: a second nut/washer/locking washer to regulate the height of the sanding beam so that it stays a consistent height. NOTE: I put the nut on top of the beam, but there were high spots. I found this out the hard way. The biggest downside of this approach is that it's hard to keep the threaded rod stable, which is why I used locking washers. I should also stress that the thread rod should go all the way through the beam so that it doesn't rock, only turn I need to figure out a way to set the low point for the sanding bar. In the end, I did the bulk of the material removal with a block plane then did the cleanup with the sanding bar.
