Sorry to hi jack your thread Mike.
Not a hijack, but a rather interesting story. Anyone using that 1 1/8" PB would appreciate any way in the world to help manage it. I can't count how many toilet partitions I installed with that stuff. Add the glue and mica both sides it gets even heavier.
There was one client some years back that opened a stock brokerage office and needed ASAP, simple desks to fit cubicles. They were 4' long, 2' wide, and desk height. The ends and top were an inverted "U", and in the front of the desk between the ends was a modesty panel (not to the floor). On one side was a simple box with two file drawers.
I had one week to make 28 desks. The money was great. But, when I had the unit of PB delivered, and down behind the table saw, I got thinking how much weight was there that I would be moving around. Then would have been a perfect time for a "Leg Up".
But the story brings back memories of pain. I laid out all the parts and pieces, so that I would maximize material, and get it all out of what I ordered. The process called for cutting all the tops at one saw setting, all the ends at one setting, and likewise for the modesty panel. That entailed handling all the sheets for each cut. It's not as easy as starting with a full sheet, and just cutting all the parts from that one, and then pull up another sheet. So, I can't say how many times sheets got moved around, but by the end of the job, I earned every penny. I think I took a day off after delivery and installation.
