    I have just woken up from a drinking induced nap and figured the dream I had about shaping/sanding the bodies squarely and quickly down to 1/4-.025 could be done. How about an aluminum sheet 1/2 inch thick 8 inches long 2 1/2 inches wide with hardened 1/4 square steel bar stock epoxied to the Aluminum in a way to not only hold the body side but the front end as well. This would make a very quick way to sand the body down quickly on my Dewalt oscillating belt sander or any belt sander. Opinions needed before I go off and embark on this experiment.

    I bought 1/4" square tube from the hobby shop, cut them down to block size & epoxied them together.
    It works, just leave some meat for the weight pockets or you'll route through the top & expose the weights.
    Or you can get a band saw from H. Freight for 100

    I plan to put 1/64 ply on top of the weight pocket area after getting the body down to 1/4 thickness I use a scroll saw for cutting all the way through the body.

    Well... my process is a bit rough but works for me. I just cut my blanks about 5/16”. Then just hold onto them and hit it on the belt sander down to 1/4” and use the TLAR method. I’ll measure to make sure I stop at 1/4”.
    I notice my finger nails are often quite short and smooth after this too. Kills 2 birds with one stone. :cool:
    I’m often too rushed to worry about additional tooling to get it exactly 1/4”. It gets close enough. That part of the build I’m not too picky with and they are quite light when I’m done.
    Just sharing my process.

    I just resaw mine on a bandsaw and I'm done.

    Another tool on the wish list. I don’t have a table saw either and use a neighbors that’s older than dirt and can’t get him back to zero degrees so I cut them fat (5/16”) and take em down on the belt sander.

    I cut my ladder and weight pockets from the bottom, with my CNC router, out of a full thickness block.
    Then, I run it through the table saw, to cut it just a little thicker than I need and sand down the rest, by hand on a piece of sticky sandpaper stuck to a nice flat surface.

    This leaves the top of the car with an intact "skin" that's translucently thin.

    Update ... this weekend I mad a jig, to hold the "thick" body, and run it through my tablesaw. No more worries of a lost finger!
