Compass Work

Over the weekend I removed to old dome and gasket and replaced it with the new one, carefully torquing down the screws in the retaining rings. It looks like I have a good seal now, so I should be able to replace the oil next. My only worry is whether I got the retaining rings back into the correct orientation for the attachment of the binacle cover. There are several holes where the screws will go, and it isn't obvious which holes are the important ones. I should have done a better job of marking the alignment. If I got this wrong, I'll have to disassemble the dome again, which means draining the oil and starting over.
