Has anyone ever used o-rings on IBM Model M or F key stems?
I know that bottoming out is part of the fun, but it would be nice to get a soft landing if possible.
I tested a rubber band from my daughter's braces, which took some work and stuffing to get it all the way in, and it had a pretty nice effect. The shape is wrong and it stretches too thin to make a proper fit, but was valid proof of concept.
Looking at plumbing o-rings, the ones I have found so far are way too bulky and stiff.
Has anybody ever done this, and did they find the right size/shape/firmness?
thanks !
