I am now in that "post building slump" that always follows a successful build. The engine worked great, started and ran almost the first time I tried it, and ran well. I did manage a video showing the engine running under load conditions while lifting a weight. Rather crude, but it did the job. I have had numerous ideas for making a machine to drive that has a variable load, but that is not as easy as you would think. It would have to cycle in and out of the "load" side automatically, but can not transfer any load back into the engine when being ran in the "no load" situation. --In other news, I got stung by a damned bee yesterday. I was mowing my lawn with my garden tractor, when I felt a small "***" in my right hand. I looked down at my hand and seen a big yellow and black bee, and immediately gave my hand a shake to knock it off. The bee drilled me, and damn, did it ever hurt. I haven't been stung by a bee since before my dad died, so it had to be over thirty years ago. I'm not allergic to bee stings so finished cutting the grass and came in the house and held an ice cube against the sting for an hour until it finally quit hurting.
