Hey everyone... I've been thinking of making an LN2/DI pot for a while, so I decided to draw some stuff up in Solidworks this evening and I'd like to know what you guys think.
The C110 portion of the pot would start out as a 96mm x 100mm cylinder that, once machined, would have a 20mm thick base and 5mm thick upper walls. Fitted to the upper walls would be a 5mm thick, 200mm long T6061 extension. The internals would consist of a stepped design with a "star" column in the center and drilled dimples surrounding it.
Now, I'm somewhat unsure about that base thickness... thinking that 20mm may be a little too thick. Granted, it may buy some time if the pot weren't being very closely monitored but it may also cause problems if things get too cold, no? As for attaching the aluminum tube, I was kinda thinking of freezing the base, heating tube and fitting them together with a press or something.
Anyway, thoughts/suggestions/comments would be appreciated.
