My dad always kept his washers separate in bread trays. Each tray was labeled by size, but two trays of the same size. That’s the backstory. One tray were regular washers, other for “”SAE”. The SAE washers were a snug fit over a bolt, not sure if that helps you out or not.
Oops counterbore. The Allen head diameter is .750”. I don’t want to use the bolt directly on the head. Thanks..
MS washers, Mil spec, have a smaller OD then normal, there are normal, narrow, and wide washers. Check Machineries Handbook, old or new edition.
I see ARP has some that are 7/8", if you have some way to turn them you may be able to gang them on an arbor and grind them down. https://www.amazon.com/ARP-2008533-10-Pack-Diameter-Diameter-120/dp/B000CFU5ZI
Used to use a lot of these locknuts on aircraft- Looks like they are formed from a flat piece, very thin but don't let go. What do they call the longer brass nuts that are found on exhaust systems? (besides long brass nuts!).
Exhaust manifold nuts.........that was easy! https://www.amazon.com/8-16-Manifold-Nut-10-pieces/dp/B01MA24C67
Had there been a recording, it may have revealed a slightly different quote. When I was serving with the 101st Airborne I heard a story that struck me as plausible. It was believed by many members of the 101st that BG McAuliffe actually said "Balls" and his comment was edited for public consumption. That was the unofficial story. Maybe it's BS, but I do know this: Army Paratroopers are without a doubt the most elegantly profane Americans I have ever encountered. I learned a whole new language there. People who jump out of perfectly good airplanes in flight tied to a piece of cloth are just not normal. Not the kind of people who use a euphemism when an eloquent stream of profanity would do.
Thank you. The cylinder head is at a machine shop getting 0-ringed so I cannot currently measure the hole. Added to Amazon cart to save information.
