Your stirling fan is really coming together.  I’m really enjoying this build.

Thank you, Per. A few small jobs still left to do, but yes, it won't be long now.
Dave and Craig, Thank you very much!

This morning I assembled the fan blades onto the hub using green loctite and set it aside to cure till tomorrow. Then I turned to making the Flame Guard. This is a pleasant hand fab job in thin brass sheet.
 “Chisels and hammers and files – Oh My!” (Dorothy, in a lost version of Wizard of Oz)


After annealing it was rolled around a piece of 1.5” aluminum rod and held with a hose clamp to set the diameter. Half was left hanging out beyond the bar so I could silver solder it. Then I turned it around to solder the other half.


Almost finished. The mounting tabs will get trimmed shorter, but they are used to screw it to the bottom of the Top Ring, so as to shield the lamp flame and the the lower part of the Hot Cap from drafts.

Regards,
Ron

Hi Ron, I have been following this from the start and it is a fun build.

That should have been sung by the Tin Man according to the test audience.

Matches the rest on the table very nicely (and that includes the heat source)  :praise2:

So what is missing besides "lighting the Fuse" ?

Not much really. Attaching the flame guard and the usual final fiddling & fettling.

Thank you, Bent! Already have. First run video is below. That horrible knocking is exaggerated in the video, but it is there. Seems the displacer is just contacting the bottom of the cylinder. Once I correct that I'll post another video.

Ron

Wow!  Congratulations, Ron! That runs really well!   :ThumbsUp: :popcorn:

Are you going t make a blade guard for the fan, or just leave it OSHA unapproved?  :Lol:

Thanks Kim! I'm going to go ahead and live dangerously, at least for now.   ;D

Thanks Chris! Runs even better now that I let the elf out!  :LittleDevil:

I find I have to turn the volume on my computer down to at least 40% to make the video sound as quiet as real life. Anyway, I'm pretty happy with it. It's been a fun build, and I appreciate all the support and encouragement along the way. Thank you!
Regards,
Ron
