Thank you all for your kind words. Packrat, I relate to you cracking a casting. One of my "learnings" was when I broke a casting in half while trying to mill it. Again. thank you all for your encouragement; makes me want to try more.
I usually never post anywhere, but this engine was a lot of work for me and I finally finished it. I am not very experienced as a machinist and this was my first attempt at an engine from castings. I will say I learned a LOT! Mistakes and screw-ups are great educators and expensive, too. :wall...
