Excellent model Dean. I liked the way you explained all the little builds of each part. Very nice.

Can't wait to see the video.

Rob, David, Jack, Mike, Bernd, thanks very much for the nice comments, fellows!

Jack, I use the gluing technique for o-rings too.  I have a couple of fat ones cut to size and super glued to use
on my WW lathe.  I don't have any 1/16" size to glue together though, but will have the right size tomorrow
when the auto parts shop opens.  So, just one more day for a video!
Hope you enjoy building yours.  I know what you mean needing to get away from long parts runs sometimes.
I'm setup to make small parts that I sell.  Sometimes, making 10 or 20 of something can be a chore!


Can you put arrows to show  were the warts are  :lol: :lol: :lol:
Regards Rob


Rob, this should do it, I think.  Didn't show them all...

Thanks again guys!

Darn it!  No video today, guys.  I'm a fibber.  Sorry.

It ran great before I painted it, as you saw in the video a few days back.  I muffed something on reassembly
and now it barely runs at all.  I'll sort it out and have a vid in a few days.

See Rob.  Does have warts!

I'll get it back to good soon.  Surly.

Too much bling, and not enough warts, I guess.......  :lol:

Good luck with the sort out Dean!  :thumbup:

I don't put "bling" on my stuff, David.  If I wanted the corners polished off, I could do that with a rasp.  :scratch:
Just for you, though, I added a couple more warts and gave it another try!


Found out what the problem was.  Had a loose crank throw.  I guess the weight of the paint on the flywheels was
too much for it.  Fixed that thing.

Now it runs just like it did in the test run before I had painted it, though somewhat quieter
since it's now on a base with felt feet.

Here's the vid.  I started it off without the fan belt on, and when it was going, put on the belt.

A funny thing will happen right after I put on the fan belt.  I thought it was funny, anyway!
About halfway through the vid, I set down the camera for a few seconds to put on the belt.
Watch the fan. 



You guys go ahead and laugh.  I sure did.










I got that fixed, and fired it up for another go.  Ran out of batteries after about 15 seconds
and the camera shut down.  It's long enough to see that it works well, though.  Actually, it
blows more air than I thought it would, and was puffing the flame on the burner around quite
noticeably.  Usually, the flame is pure blue, but the extra air going into the hole in the firebox
was turning it yellow. 

You can see my hand trying to reach into one of the bottom arches to reach the air mixture
on the burner, but couldn't quite see to get it and run the camera at the same time.







I suppose that'll do.

Dean, that fan looks like a real winner, just a minor blip to deal with, keeping it on, but overall, that's one fine running engine, and a beauty as well.  You might try ducting the air supply for the burner in separately, to reduce the fan's interference, or maybe cover the upper holes on the sides.  I can't say I've ever seen a better running Stirling engine, and really look forward to building my own, so I can enjoy it as much as you seem to.  Top notch job, all the way around. :jaw: mad jack

Rob, David, and Jack, thanks much for commenting! 

Mad Jack, I think I'll just put a baffle in the hole.  That should probably do it.  I was kind of surprised that it blew that
much air down into the firebox, but it sure does.  I can feel a steady stream of air over the cylinder too, on the side
opposite the fan.  It really blows..
