Ok before I get started I realize this may sound like a hair brained idea, with that said;
I was reading up on a product called star board
It got me thinking is there any reason that a "plastic" cutting board could not be used as backing plate material?
I guess what I am wondering is what are forces applied to backing plates?
I understand that they are used to spread load over a wider area but from a load bearing stand point why not use cutting board material?
Feel free to slap me around for suggesting such a bone head idea, curiosity is going to kill me one of these days
p.s I know nothing about star board, have never seen or used it , it just reminds me of the cutting board on my kitchen counter.
