Yeah, I'm nowhere near building an engine from scratch though. I was building chassis/mounts/shafts/sprocket drive/etc for a little skid steer R/C but I've parked that project, I have a wrap up video I just need to edit on it. Long/short though, I'm not pleased with the design, it's too finicky and fragile. I will likely re-design and try again with what I've learned (and now that I have a mill to make some of the parts I couldn't make the way I wanted to before), the electronics were solid but the sprocket drive was super annoying.
Here's the playlist on everything I've done there though if you want to see it:
I'm not poopooing that thought Len. What you say is true. It just reminds me of an interesting chapter in my life.
I worked for an auto company. For a period of time, one of my responsibilities was to review all outside suggestions - which included inventions.
About once a month we would get a letter from some character who had an idea for an engine that could run on water or lightning or...... They just needed a few million to develop their idea or a few million for the rights to it.
It was a painful job at times, sometimes downright hilarious, and sometimes we also got fantastic ideas from really creative innovative people.
I hear you . . .
I was developing Food Processing Equipment for Kellogg’s in the 1980s, but, my Patents came from Plastics Forming in the 1990s with Big O Machinery.
I thought the cereal industry was clean and innovative, little did I know that corrugated HDPE would send me around the world and into the mainstream of cutting edge manufacturing in North America.
This definitely is a great place to receive encouragement on tool purchases.
Good luck with your dream of building an engine!
I purchased an electronic version of the book/plans by L K Blackmore for the 1/4 scale Bentley BR2 rotary engine from Camden Miniature Steam Services. It’s very very unlikely I’ll ever build it, however the book is great for showing how to make such a complicated model engine.
