Gold Blend. Dark Roast........
« on: September 18, 2013, 11:01:38 AM »

This is my, "Gold Blend" engine. During construction...........




 At the recent show. Running very well, as usual.   :ThumbsUp:

Towards the end of the day, I went for a walk round, to see the other tables. About 1/4 hour.  :)

When I returned, black smuts were coming from the firebox. And it was blummin HOT!!!  :o

The twin, beeswax candles, had spontaneously combusted........   




Balsa wood doesn't like high temperatures.........




The outside of the cap had a thick coating of soot. And, some pretty colours inside........




And a sticky, smelly deposit on the piston and displacer rod. Action jammed.......




Time for another rebuild!  :facepalm2:

Sigh.......

Yep...I would say she got hot alright!!  Doesn't look like any damage that can't be fixed though...and a very nice looking engine too David!! When you get it back in ship shape, I would enjoy seeing a video of it running if possible.

Bill, Dave.

Thanks for your comments!

Nothing that can't be fixed.......  ;)
 
Here's the build story, and videos. If you have the time...... http://madmodder.net/index.php/topic,5732.0.html

Hmmm...... Almost a month gone, already!  :o

Not had much workshop time, recently. Just a few minutes, here and there......  :shrug:

I made up a bundle of offcuts, to give a 4" square cube.........




And started to turn it into a former, for the new displacer. Messy stuff.........




Finished article.........




Wrapped tinplate around, and soldered the overlap..........




Two off, 3mm thick end discs. Thinned to 1mm, where possible........




The wooden former, held the disc square to the tube, while I drilled for 6off 1.5mm dia rivets

Natural ingredients only, for my engines.......




Then rolled the tin over the end cap, and tidied up with a gentle touch on the grinder.........




Internal boss for the 4mm threaded displacer shaft.......




Held with 2off M2 grubscrews, and hi temp sleevelock........




The assembly spins true, within half a mm. Close enough........




Initial runs, on twin candles were disappointing.
The hollow displacer sounds to be grinding/ grating as it slides through it's bush. Quite noisy!

Not a coffee table engine any more!

The new displacer weighs 94grms. The original one weighed 69gms, after toasting. The extra weight caused a hesitation, getting over TDC.

So I added 3 extra,  2" x 1/2" x 1/8" weights to the flywheel........




Didn't make any difference!

So, I tried with my temporary meths burner, and it ran happily. Well balanced, even up to blurred revs.  :ThumbsUp:


I feel another, stainless burner coming on.......  ;)

Tht's got to be the best looking "can" Stirling I've ever seeen.  Nice work on that thin metal there.

That thing looks huge, what's the bore/stroke?

I simply love Trecle !! Is that how it’s spelled ? Never called it anything else. I grew up with the stuff, but haven’t had any in years. I haven’t been able to find any in the states. While I was deployed overseas I ran into some British soldiers and asked them if they had any Trecle….they all laughed at me for asking that way and said I must be really old to call it that !! I'm not that old !! But in the end I had acquired a big tin of the deliciousness. I reminded me of home while I was in a very hostile environment !! It was very soothing at the time and place to have some home comfort reminders. Anyway…just thought I would pass that along…..good use of the tin !!

Dave V45.

I too have enjoyed treacle ("treekl"), over the past 70 yrs. Never did/ do call it by it's correct title!  :LickLips:

Use it in my morning porridge. Also, I use it in the flapjacks I bake, for my other forum's members........




Never forgetting to finger clean out the residue, before washing and storing the empty tin.   :P

And..... Here's the burner, that was coming on, a couple of weeks ago! 

Usual build. Top of a salt grinder/ pot.
Brass disc, base, with central locating bar, and supporting foot underneath the wicktube.......




The crossbar locates nicely, in the rim of the bowl/ firebox.......




Until, my fumbly fingers knocked the burner, fully inside the firebox!   :facepalm:
The only way to retrieve, was to lift the hot engine, while it was running.  :(

A taller, breather tube, stopped that happening again.........




Here's another, final video........

Job's a good un!   :cartwheel:
