Exhibit Hall #1 : Vacuum Failures
 |
| name of piece: |
11" ASA to 10" Conflat Adapter |
| artist: |
John Boffard |
| date of acquisition: |
1990 |
| description: |
This expensive piece of Stainless Steel was made exactly as specified. However,
the bolt circle for the twenty four 5/16-24 bolts had the last two digits in its size
reversed. 9.128" became 9.182".
This flange was the first exhibit of the Hall of Failure.

(taken directly from MEL's lab notebook)
Getter Pump. (Yeah, I got sucked in to the big lie like a small furry woodland creature
by a bear).
Given our interpretation of the technical data presented in the engineering bulletin, we
calculated that with a 4 inch piece of the provided sample Ti-Ta wire we could make a getter
pump which @ 10-9 torr could pump 10,000 l/s. Heck even if we are a couple of
orders of magnitude off, we still have a pretty decent pump.
The assembly drawing is shown below ...(but I suspect that one will be able to view it at
one's leisure in the hall of obsolesence).
Editor: What insight!

| name of piece: |
Plate Nuts |
| artist: |
John Boffard |
| date of acquisition: |
1991 |
| description: |
Used in the right way, these nuts simplify the assembly of vacuum chambers
and flanges. But with a few crossed threads they become a painful nuisance on disassembly.
Curse this superhuman strength! |

| name of piece: |
Flexible Coupling |
| artist: |
Garrett Piech |
| date of acquisition: |
1993 |
| description: |
Part of the Quenching Fiasco, this
mini-flange flexible coupling spontaneously developed a 1×3mm hole in it,
while Garrett was watching it. Curse this heat-vision! |
