Hex ID washer revisited...

A while back I posted asking if anyone knew a source for hex ID washers. Never did come up with a source for a small quantity. Someone suggested cutting up a socket, which gave me the idea to cut up a mild steel 9/16" hex coupler. Found one at Shoups (of all places), and chopped two .25" sections off in the lathe. (3/16" would have been thick enough, but what the heck!)

Problem solved!

I missed the previous post, but have to wonder what good that will do? Won't the washer just slip off the head of the bolt when tightened?
 
Working with a little golf course "truck".

The brake and clutch pedals have flanged nylon bushings inside their pivot points with a sleeved 3/8" bolt passing through the bushings.

The bolts AND steel sleeve pass through the attachment points under the "dash".

Over time, the steel sleeve rusted/stuck inside the nylon bushings, so the sleeves and bolts were pivoting in the attachment point and wore the holes "oblong".

I welded 'em shut and re-drilled them, and installed grease zerks in the pedals.

A hex I.D. washer will be welded to one of the attachment points for each pedal holding the bolt on sleeve from pivoting and wearing the holes again, yet allowing easy disassembly, if ever needed in the future.
 
I ran into the same situation 30 years ago, working for a company that made automobile scrap shredder rotor assembles. Think of a HUGE hammermill feed grinder, rotors were 9 feet wide and 6-7 feet in diameter, some 8 ft in diameter. Shafts they mounted on were 15-20 inches in diameter and 15 to 18 feet long. We bought 2 inch and 2-3/4" diameter Stressproof steel bar for tierods to hold the rotors together, look Stressproof steel up, Excellent material for bolts, threaded the ends for big hex nuts, and I needed hex nut locks round on the outside, hex on the inside and about 3/4 inch thick. Local steel service center burned them out of mild steel plate. ANY tubular steel I talked to anyone about with the 6 inch OD and 3" or 4" hex ID I needed wanted Thousands of Dollars for tooling and minimum orders of a thousand feet. With today's laser and plasma cutter technology smooth net shape cut parts are easier today than back then.
 
Very slick job. You are not the only hodge podge inventer out there. I modified the mowing height "deck height gauge wheels" so they dont wear out. The centers of thise plastic wheels get dust and grit in them from mowing. After just a few hours if you give them a spin they wobble and chatter. Well not any more. Made steel bushings out of 3/8 pipe and cross drilled the original sholder bolts so now they have zerk fittings and the wheels can be greased. Smooth and slick as can be. Just love little things like that. Gives you a dose of pride. Just finished this about an hour ago. Going to put a little horn on my Cub Cadet mower. Was a little corroded from a junked car and I wire wheeled it and used real IH paint. Came out nice and pretty.
