ITMy lower ring heater installed
The install of the lower ITMy ring heater was completed Tuesday evening. There was a small issue with fit for SN#203 glass former assembly, the nichrome was a tight fit into the macor (not nearly as bad as SN#210). The diameter of the glass and nichrome near the end was 0.276", some chipping of the macor was seen after the glass was seated. The temperature sensor (RTD) has loosened some, apparently from the re-install efforts, about the epoxy but is still showing the same resistance as before (109.5 ohm).

A few more pictures. The first one shows a small amount of chipping on the macor that happened during assembly. This is significantly less than last time however. The second picture shows a casualty of uninstall, re-bake, and reinstall. The RTD has started to come loose.
