Post subject:  Universal mold spreaders?

Tired making new spreaders specifically for every mold I make, so first attempt/prototype at a set of universal spreaders for letting freshly bent sides settle in the mould and gluing on the linings.
May yet have to shorten the tubes/lengthen the threaded rods for the upper bout and waist for anything smaller than an 00.
I already have one for fitting top and back to sides to make it easier to remove after gluing.
This is the first side for a student's SJ Hybrid.

Nice idea. I might have to try that one

Nice design. I like the padding on the blocks.
I have been using turnbuckles for the ones that need to come out through the soundhole. For the ones that come out before the box is closed up I have been using the cheap HF plastic bodied F clamps turned around as spreaders. They aren't terribly strong but work fine to hold the sides against the mold.
