So all parts came in to construct the manual vacuum rotary feedthrough. I will use this as a proof of concept and possible will stir some propellant with it before upgrading to the motorised unit. It took me a good 2 hours to machine the temporary shaft and base part. The shaft was machined slightly conical to

Just modelling a rotary feedthrough for my vacuum lid using off the shelf items. Did not test whether the “reversed” rotary shaft seal will hold the vacuum. It consists of: 10mm ground shaft with machined groove for circlip / e-clip 61900-2RS1 – Single Row Deep Groove Ball Bearing. 22x10x6mm Standard rotary shaft seal 10 x 19 x
