So here is a plan for an inexpensive panel saw. Short of industrial equipment, its hard to find something easier to break down large panel material, than with a panel saw. Purchased units are quite expensive and many diy plans are built for heavy use. I have at least one for a future upload. This plan is inexpensive and relatively easy to build. For the home DIY'er who occasionally has need to break down sheet materials, this will simplify the process and save you lots of time.
This is another project from R.J. De Cristoforo published in the 1985 Popular Science DIY Yearbook.
R. J. is no spring chicken at this stage of life, but he makes it look easy to use the panel saw to break down full size panels.
