While waiting for some parts to arrive I made up a list of things to do before the engine can be reassembled, you can probably not read it but it says rebuild the oil return, fit new Hobbs oil pressure switch, true the compressor spacer, make new piston ring seal housing and send the rotor away for rebalancing.
My friend Lars-E (one of the V1 pulsejet sled guys) offered to true the comp spacer in his grinder at work, it lost a little shape from the heat when the piston ring seal got destroyed so it needs some work.
Tonight I have been making parts for a new and improved oil scavenge line, the old one was made out of hydraulic tubes with metric threads cut so deep that I constantly worried that they would snap when the external AN-connections were torqued in place. The new steel ones have UNF threads that aren´t nearly as deep as the metric threads, I´ve also added a flange on the inside so they can be torqued without stressing the connection tubes.
Here I have just cut the old tubes to fit the new steel ones, a look at the workshop clock told me that time had rushed by so I had to call it a night. When I got back inside and happened to look at the kitchen clock I realized that the workshop clock was still running on summer time and therefore an hour ahead. Damnit!
Cheers!
