Impressive work Mr.Phil!
SIde story on the use of unusual clamps.
I used to work in a crating shop some years back where we would put every thing from air filters to animatronic dinosaurs and everything in between into wooden crates.
We, as a crew were packing up some mobile target presentation units, the machines on small gauge rails that would pop a target up from behind a berm for the soldiers to shoot at, for the US Army.
In personally was working on a prototype piece for another customer and had 2 fairly large pieces of particle board about 1" thick each that I needed to glue together and no clamps big enough. Then I saw the stack of 3 of these already packaged mobile target units, about 4000 pounds in all and $250,000.00 a piece just sitting there. Yup, grab the forklift, lift one end, set it down and presto! A $750,000 wood working clamp.
My boss just shook his head and walked away.
