Poppin's alive!

[student_Machinist]

Hi every one
After a lot of procrastinating my poppin is finally running! this is my first running engine. The video below (hopefully it works) is of it turning over reasonably slowly

it was remarkably easy to get to run, fired up first try!
Still needs webs cut in the flywheel, base and burner to complete (btw please excuse the rubbish burner in the vids : ) not too bad for an 18 year old eh?
Special thanks to GailInNM for generously donating the graphite for the piston and every one else who helped in my previous threads

Regards
Jonathan

Remarkable! Amazing! From what I hear engines of that type are supposed to be a bear to get running. I'm glad that nobody told you that. It is a very sweet running engine that you have there and you should be very proud of it just the way it is. Thanks for sharing it with us. :bow: :bow: :bow:

Very nice engine,
I haven't built any stirling engines, yet, but from what I have been reading, it seems like to get those engines to run properly, it takes a lot of extra precision in the machining department, to get everything to run smoothly.

So great job not only in the build, but also in the precision of the machining you did in that build.

Thanks every one for the support (one of the reasons i love this forum)

haha that was the first thing everyone told me

I'll post some pics when i get it finished. Btw i dont know if this is common knowledge or not but does any one find stainless swarf to be quite dangerous? in the way that i managed to cut my self pretty bad making the flywheels, it kept winding its self around the chuck and flailing round, before i could turn it off it caught my hand :-\ God that stuffs sharp

There is faith in the hot air engines! "Poppin" probally the classic configuration of its type. We all feel like 18 when our models come to life and when you are 25 you be glancing up on the shelf where Poppin started it all for you. .

Nice Job, Jonathan! My poppin is gathering dust in a corner of my shop. It's waiting for me to start over and see if I can get it to the point that it's half as nice as yours, and maybe even running!

Congratulations!

It looks great. The base looks really nice too.
