Spanner from the Past

One of the Internal Combustion Engines (Dresser Clark)I was responsible for had a "CROSS-HEAD" (like a baler PLUNGER /CROSS-HEAD).
The "Jam Nuts" maintained the Compressor RODS secure to the CROSS-HEADS....this Spanner is from the Neanderthal / Cro-Magnon time frame.
I happened to be in my shed of memories.........
With the Spanner mounted on the NUT.....a Hydraulic RAM 2" Diam. was placed at a specific location at the lifting eye end of the spanner. Then the appropriate oil PSI was then applied to the ram...
Torque= Force X Radius Distance:
All a distance memory..................:)

Reminds me of the wrench they used to adjust the U-bolts that the steam drum hangs in, in a very large boiler. They were longer and had a hole for a clevis so you could pull it with a air tugger.
 
Good morning Russ......Trust you and your sweet heart are well and enjoying Sunday......;)

That was a very common thing back in the steam locomotive days. You would see a wall covered with great big shop made wrenches like that. You couldn't order then from snap on sparky. Piece of 3/8 or 1/2 plate and do a whole bunch of drilling and file work by hand. You would assign that work to a new kid. Take bets to see how many days it would take him to finish the job. Tourch will aneil the metal. You can always harden it a little if desired. Today you can run a bead of hardened welding rod and then precision grind it to exact fit. Steam locos have some pretty big nuts on the drive rods. Everything is double nutted too. Some stuff is even tripple nut. Just for giggles I made a special wrench to remove the wheels from mixing bowl dollies for Hobart mixers. Piece of 3/16 and a lot of hand work. Had to slip in between the cast frame and the swivel of the caster. Darn tight fit. Man some of the stuff we did when younger!
make your own.
 
When he started with a forklift fork I was hoping he was going to carve out a 3 1/4 inch or something
 
And I'm guessing the eye bolt was added so two men could conveniently carry it between them on a bar or pipe on their shoulders.
