The PC router is an industrial type that takes two wrenches: 9/16 & 13/16
I expect it will work. It looks like someone is making them out of 9/16" CR bar stock. How hardened and tempered it is can be anybody's guess. For sure the one that's in there now could use an upgrade. In the early 1980s I made a 3/8" router collet for a 690 router and though rarely used, its still good today. I do quickly admit it didn't have any threads to wear out.
in a barn? How big are you talking about? A giant ferris wheel could have a diameter of a several hundred feet. and then there are barn doors...Yeah, looks like they also have chicken poop. Strangest find that I know of is one Corkie Powers made. (Corkies is ride operator for State Fair.) He found a COMPLETE giant Ferris Wheel in a barn in Conn. Been there since in the sixties, and was forgotten.
Oh... they disassembled it. How disappointing."in a barn? How big are you talking about? A giant ferris wheel could have a diameter of a several hundred feet. and then there are barn doors..."
I guess you have never hung around after the end of a carnival and watched the Ferris Wheel be dis-assembled for transport. They are taken apart and loaded onto a semi trailer. A crew of two can do this in under an hour, and mostly from the ground level. Going up takes a little longer, but the technique is nearly the same. A barn large enough for a semi box trailer would hold one easily.
Watching this process makes you wonder how safe they are when assembled.
