Very interesting, Alex. I had a look at the site, those disc springs seem ideal. I thought by spring washers you meant those washers that are cut open and twisted…
How did you go about picking the right strength for them? What is a good Newton value to shoot for if they are to carry a mirror cell? I suppose it should be at least an order of magnitude larger than the weight of the cell (at least if one wants to do away with locking bolts)?
Cheers
Steffen.
