Awesome Tom, Copper FTW !!!Plan B again, again. So the ARC has a in house made crankshaft locking tool used when torqueing a flywheel nut.
I gave serious thought to making one, but unless I do more than one of these up grades it is pointless and my heirs will have no clue and dumpster my work. So KISS. Many times in my life immobilizing a precision round surface was necessary.
Using copper or aluminum of sufficient thickness to guard the jaws of Vise-Grips being the most common griping tool.
So once more eureka!
3/4" copper water tubing walls are thick and grippy. So I turned the engine crankshaft key way to face the moving jaw of the Bridgeport vise.
Sleeved the 2" x 5/8" dia. key slot area with copper tubing. Orienting the shaft keyway into a vise jaw for maxim grip.
Torqueing to 46 foot pounds was Duck Soup. Crankshaft never budged. KISS wins again.
I hear you, but we don’t have that saying in Texas, lol.Nah! There is a saying about a robins, they have to have snow in their tail three time before warm Spring weather comes.
It has flurried off and on all day lower thirty's tomorrow will be mid fifties. Thank-you Robins.
