Those stupid cards they stuff in every pack are (plus or minus no nevermind) .005 inch. This is a supply of .005 shims/spacers/whatever just lying around. Any one else got a favorite shim stock that is common?

According to Ken Davey :
Modern aluminum beverage cans -- 0.001".
Enjoy, DoN.
Zigzag paper...,001
Found in half the tool boxes in So.Cal
Some are even used to set tools....

Hmmm... the cans I used to shim the headstock of my Gingery lathe were
0.005"....Best -- Terry
Sounds like Tom Gardner should source some of that .

White or bamboo? (Not that I'd know the difference ;)
How many is that in RCHs?
Grant- Western Family diet cola .004", Coors-a-cola .004". This was after the paint and liner were sanded off. The inner coating and the outer paint added less than .0003" ERS
Yeah, I think cans are thicker than a thou, which is the thickness of aluminum foil if I recall correctly. That's not enough thickness for rigidity.

According to Harold and Susan Vordos :
[ ... ]You both may be right. I don't have any empty ones to measure right now. But they are amazingly thin -- depending on the pressure inside for their strength when in storage.
And they are a lot thinner (and weaker) than they were when I was a kid -- when they were the alternative to brown long-necked bottles, not the green or white glass ones for sodas.. :-)
Enjoy, DoN.
And they are a masterpiece of the toolmaker's art. The methods developed (with some of the critical methods developed by Coors Brewing) were 'way ahead of their time, for back-extrusion and for the high-precision tooling used to make the self-contained pop-top.

Russian, Irish, or American RCHs?

Years ago I saw a slow motion video of a pop can being extruded. There was a puck of aluminum sitting in a die about .500" deep. A highly polished ram crept downward (slow motion afterall). When the ram contacted the puck the aluminum shot straight up the polished ram, almost too fast to see. Amazing. ERS
Yes, it is. Back-extrusion was an established technique, but it no way as dramatic as it became with the making of aluminum beverage cans.

I heard it called Impact extrusion a long time ago. I think when toothpaste tubes were made of metal. Must have been about
35 or 40 years ago. ...lew...
Yeah, it goes 'way back, and I think that brass cartridges have been made that way since early in the last century.
When aluminum can-making got going, there was a lot of fancy toolmaking work involved, which raised it to a new level.
