Splendid, I'm still following along (I can't find an emoticon for cider )
Hey ChrisInteresting..! Another way to make elbows I usually make them on the lathe - just as a long version of a straight fitting - then cut them into 2 parts at an angle of 45° and silver solder them together again. The last step is then filing the edge of the elbow to a more or less round shape. Oh and you build is of course excellent! I always like the more complicated stuff because its more interesting to watch Florian
I do love plumbing ......55 years ago, an apprentice was tasked with plumbing up a small pneumatic machine with 1/2" copper tube & Yourkshire fittingsI was so proud, all the tube lines were square & neat....valves & elbows & unions all nicely soft soldered in All was fine until the air was turned on & of all places, a leak at the pressure port...........Shock horror I couldn't rotate the pressure supply tube from the port as there was no union installed........Derek
I go without internet for a few days and I'm pages behind! Nice work on the engines, to answer a question about why the cranks are 90 degrees out of phase, its likely to give the engine a positive way of starting, if they were 180 degrees opposed you could get stuck at TDC / BDC and the engines wouldn't self start. Operator comfort (from vibration) wasn't a big concern I'm guessing - based on the other details you've shown to date!Mike

They remodeled their bathroom, did all the work themselves. Came out looking great. All done, they turned on the water supply. Filled the toilet. All good. Gave it a flush, no leaks then they noticed the steam rising from the bowl. Yup, swapped hot and cold lines in the floor...
