Oh. Yeah I've read all of that. I thought you meant that you had OTHER cheaper+easier alternatives. Sorry for the misunderstanding.

So I have been fiddling around all afternoon with this thermal press fit idea. Please keep in mind I am in rural Missouri on a Farm with antiquated tools and not at Cornell right now.

Few...

Can you suggest the safer cheaper alternatives? I know there's no mechnical benefit. I'm looking for the flush pin aesthetic.

Later when I am home again I will post some drawing I did with regard to the forces I believe are in the scales, and please can people comment on that time? I'm really curious about this. (Note: the...

Glen can you please elaborate this is very interesting but I'm not quite following...

KevinT- Just because it is in tension (which you are correct that it is) doesn't mean there are not other...

Isn't a blind rivet sort of what I was thinking of? Expanding metal into the scale? Correct me if I'm wrong, but putting the male end into a female end spreads the female end, creating a press fit...

it does in fact place shear on the pin... the compressive/tensile forces due to flexing are lateral in the scale, which is normal to the pin, which is shearing. Trust me. I am at college for...

how does one taper? did you use a countersink bit?

razor scales flex because the tang is a non-constant width. Slowly open and close and watch. I THINK this might be by design as it sort of acts like a spring to resist movement, making your scales...

actually, since the flexing of the scales puts them in compression/tension along their length, this increases the shear (perpendicular) force on the pin, there by increasing normal force and...

I don't foresee many scale materials cracking under .005" displacement... Open and close a pair of scales, see how much they flex. Flexing creates greater stress than simple compression, as it puts...

If my education serves, every metal has a specific temperature-deformation constant, denoted alpha. This is linear within the elastic range, which on the cold end of things is pretty far. You will...

I'm getting some liquid N2 from my dad this weekend and will be testing in my downtime in the evenings.

I suspect that an interference fit would cause cracking if the actual differential was say,...

NO... you dunk the pin in liquid N2 so it contracts. You then insert it. as it warms it grows slightly, which will then pressure it in place.
I said 1/16" as an example. One would have to figure...

I assume you think the whole thing will be pressure fitted... but if the pin still has clearance on the blade, the razor will still open and close....

This will seem like blasphemy to some people and I have mental images of horn scales exploding and bone scales breaking and wood scales cracking and people crying and babies dying, but would it in...
