On the Series front, I am done for a while, I removed the oil sump and did some cleaning down there, I hope the leak it had is gone now and I could double check the engine is indeed a 5 bearings one. I looked at one of the brakes that was binding seriously and after cleaning and placing the sprint right, seems to work much better, but the brakes may need overhauling soon. We'll see.
I saw this video of SCLR, this is part of the trail we did back a few years back, to bring materials to rebuild the bridge shown on the images. Very cool.
