The bearings went out on our reactor turbo pump. It started making a loud whine. A rebuilt Leybold 150 costs like $4000, so swapping them out myself seemed like the only real option. Here’s how it went: Step 1: Remove the heatsink and housing. Use a metric allen wrench to remove the housing. It’s got a rubber o-ring holding it […]

Designing a 3D-printed flow chamber
I’m working on a small, water-tight chamber to measure how flow affects feeding kinematics in Vorticella, a single-celled protist that adheres to surfaces. There are some real design constraints, namely that it must be small enough to accommodate the relatively short (10mm) working distance of the objective lens we’re using. I designed a prototype in Solidworks. The clear interrogation area […]
