As the title indicates, my niece who is ten and has already been moved to the advanced placement program in science which she loves. I thought a nice gift for her (and project for me) would be a small Stirling engine.
I work with 99% cast iron at the shop and the only scrap brass there are beater bars.
Reading up on the different alloys available got me a bit confused as to which on would work best, machine well and be nice looking when polished up and mounted on a wood base.
So I ask if anyone has built a Stirling what alloy did you use and with what results.
I figured for the first one; prototype I'd us what I could get and see how it goes.
If anyone has some scarp round: ~1" to 1.5" in dia., length 1.5" to 3" plus and flat stock 0.25 to 0.385, square inch and above. I will of course compensate for postage and "scrap fee"
I love to see kids taking an early interest in science, any academics at all really these days. I just remember when I got my first old used RCA oscilloscope in the early 80's. It lead me to teach myself electronics, then an undergraduate in biology, followed by a masters in neuro-pharmacology and best part of a doctorate in the same field. Okay how did he end up in machining? "...What a long strange trip its been..." story for another time.
Thanks everyone any help will be greatly appreciated;
Alex might even want to be a machinist! She's quiet the smart cookie, got to AP cause she was bored in the regular class and took to annoying the teach to pass the time.. just like her uncle
