Just one very, very minor observation Chris. Nuts with each face chamfered are not usually encountered in this class of heavy engineering. The face against the part being retained is usually flat. Double chamfers are for general purpose nuts in the hardware store is my understanding.
Goodness Swarf Maker .....when considering Chris's nuts, I am sure careful consideration was made relative to relief angle [no nuts were ever designed to have 100% [flat] engagement, but reduced by 1/96th negative to the AF dimension]Then we must consider flat washers were never just those punched out rings, but a Graded Carbon steel, machined, then heat-treated to acceptt the induced torque Naturally when I quote 1/96th, as obviously being Imperial [as copied by the US] .........I am sure Chris has any issues with his nuts in hand Derek-----------PS...sorry ..I cannot see your location, however if in Europe & using the Si System, then nut face relief face /angle would be reduced by 1/100 th negative to the AF dimension]
The solution is simple at this scale.Assemble the engine then gob on a couple thick coats of paint over the nuts, brush painted of course. When you're short of REAL work you send the apprentice - in your case elves - out with a bucket of paint and a paint brush, not a spray-gun. (At least that's what happened when I started work many-many moons ago.)It'll look just like the real thing, and you won't be able to tell if the nuts are chamfered on both ends or not.Don
Starts out fine, then the paint flicking starts
It's a good thing the elves don't know about OHSA, and even more importantly that OSHA doesn't know about the elves. Otherwise you'd be buried in the paperwork for their Lock Out Tag Out violations.Don
