If electrolytic corrosion wasn't bad enough, there's always the joy of crevice corrosion too...

Re: Spring Force

Thanks Bill.
I have had a great electronic conversation with David Quinn too where the same figures came up. That sort of underlines the 'rightness' of feeling.
Cheers!

Re: Spring Force

Actually, I'm thinking of torsion springs... I'm not sure if it is going to be practical with the limitations of space in a 'traditional' key block. Of course, getting really clever, the blocks could contain the windings and the whole arrangement could be made almost invisible and have very little f...

Re: Spring Force

I'm thinking of having a 'play' with an idea, but I don't have an example to hand to see what the actual force is when the keys feel right.
It's a bit like an automotive poppet valve, I suppose - only enough springing to get the job done.
The problem is quantifying how much is just enough! :)

Re: Key Axle Pins

316 St.St spring wire might be worth looking at. There is another common grade of stainless (not 304) that springs are made of too.
1/16" should be relatively easy to find...
Are the brass pins a bigger diameter? I'd expect them to be slightly larger.

Re: Key Axle Pins

Thanks David,
If my understanding is right 1" finish nails are 16½ gauge, which is Ø0.058" or Ø1.47mm?

Spring Force

Hi, I know, two odd questions at once....! Has anybody made an investigation into how much force makes a chanter key 'nice' please? Also, is the ideal to have each key feel the same? This would make a lot of sense, but many things in life are counter-intuitive. You could look at a sensible maximum b...

Key Axle Pins

Admittedly, this is probably a slightly odd question for a very first post... Is there any consensus for pin diameter or material please? From my occasional work with a clockmaking friend (see www.clockmaking.co.uk if you are interested in horology), the use of brass on steel minimises wear - hence ...
