Lock nuts: the engineer's view

[DownWest]

I borrowed an old NSU quickly from a workmate when my "real" bike was off the road. It was three speeds with a dual seat. My girlfriend wanted me to buy it.

You guys crack me up...
I did date a girl way back who had a bike licence; She then showed me a pic of her doing the 'wall of death'.. Feet on front and rear hubs while wizzing round at the top of the tub. She worked for a bank when I met her..But liked my Greeves.

I've never heard of palnuts.

Has me puzzled, remember them from the 50' used for light assembly on domestic goods, holding speaker in a radio. All you needed was a plain peg, drop speaker over pegs, put nut on peg, place hex socket drift over nut and hit with hammer, nut slides down and lock in place. If you need to remove for repair screw off with socket. top face of nut forms a thread that scew's it's way up the peg, thus fast to fit, cheap to make, no thread.

Those things? Seriously? The're not proper nuts as they are only suitable for very light loading .... as you say, small speakers in a radio or low power fans in an appliance, which was the last time I came across them.

That's why the thread had me puzzled, what use could they find for them ?

When all you have is a hammer everything looks like a nail...

The cross head is for taking them out. Then you need a screwdriver.

Not quite the same. What you were using were starlock washers

No not them, Palnuts, it saved cutting a thread and normally came apart the odd time needed, when making volume fractions count. Certainly would not use them were any load was envolved.

No one use Value Analysis these days ?

Its not worth the time

It was a bad day the day we got Universities evolved with engineering product design.
