What's Happening Wednesday?!? We toured the HeatSync makers space this week! Great to see places like this providing really neat opportunities in the local community. We are excited to help them going forward! #heatsynclabs #er2 #computerrecycling #er2mesa #beresponsible #reuse (at HeatSync Labs)
Inaugural Brigade kick-off. This is going to be great! #cfamesa #cfa2014fellows #cfabrigade #heatsynclabs
Safety first. #heatsynclabs #cfamesa #cfa2014fellows #codeforamerica
Our first CfA fellows meet n greet. thanks to #heatsynclabs for hosting! #mesaaz #cfamesa #cfa2014fellows

Turbomolecular porn by hslphotosync on Flickr.
The turbomolecular pump has been attached! The largest flange on the chamber is a KF-50 for various reasons including cost of fitting hardware. Above this size, ISO fittings must be used and these are much more expensive than the KF style.
The turbopump that was donated to the project uses a 4.5" CFF conflat style metal knife gasket mount. 4.5"CFF to KF-50 adapters are several hundred dollars so it was decided instead to machine an adapter out of aluminum and use a square lathe-cut viton gasket instead of the soft metal gasket. The gasket was purchased from ANCorp for $14.50. The 3x5" aluminum stock was purchased from Industrial Metal Supply for $22. But of course nothing is free, the 10 hours or so it took to machine the piece is worth something right?! Luckily time IS free!
The profile of the piece was turned first, with the KF-50 end on one side and a square shoulder on the other.
Though I suppose its not completely necessary when using viton rubber instead of metal as a gasket material, I attempted to machine the knife edge into the face of the CFF half. The circular sawtooth would normally bite into a soft copper gasket but of course that's not possible when using aluminum for the flange material as the aluminum is too easily deformed. Stainless is too expensive and I'm not sure I have the skill required to pull it off just yet... The knife edge came out OK, though slightly over sized. I must've been tired or something.
Finally the hole pattern was added using a mill and a (horribly undersized) rotary table. A very long day at the lathe, and a somewhat tired yet nonetheless glorious victory!
Edit: If I made this piece again, I would probably have attempted to make it tapered from the CFF bore to the KF-50 bore. If I ever come across enough free time and another hunk of metal I might just try to machine another one and compare the pumping speed between the two.
SEM Vaccum Chamber by hslphotosync on Flickr.
The vacuum chamber has been welded!! HUGE thanks to Karl Kammerzell and his welder David Iannaccone for making this project possible. With this HUGE obstacle out of the way I am excited to proceed onwards!
