That's sooo good, David! Your good job shows in spades with such a large engine running on that tiny flame.
Kudos, my friend!

Excellent result David ... just goes to show the research you put in paid off I think, your work upfront with the design and how it was eggsecuted is what made it run so well on the tea light.

G'day David, just read this thread, what a clever design/build and you could not wish for a better result, runs great.

I don't know any egg yolks so I'll just scramble outa this nest!!

Thanks for all your kind words Chaps.

Chuck, It would run very well on a stove. Not sure how long the balsa displacer would last though!

Singed it, with the meths burner. But, the tealight does it no harm.

Hi Bernie. Nice to see you've joined in.

"Finished" the engine today.
After warming up with a drop of meths, it ran on the tealight for some 2 - 3 hours. All ok!

It needs a base/ firebox now.
Found a stainless steel dog's bowl, in Wilkinson's for £1.35........

Very nice to see it running on a tiny tea candle, David, and a very interesting use for that pan. The next project I expect will use the rim and remains of the omlet pan I expect, right? It never ceases to amaze me how quiet the stirlings are. That is a fine runner, and a good show of what can be done with just what is found lying around. very nice indeed!

Cheers, mad jack

There's nowt wrong here.

But, we do have funny neighbours. Them over the fence, who cause all the problems.......

Would you like to have to live next door to you?

My neighbours think I'm a little treasure ...

I sign for their parcels ..

And victimise them with my tomato glut ..

I also keep the noise below 140 dBA ... err... occasionally.

PS Taller fence ???

Adapted the feeding bowl/ base.

Piece of 10mm ply. 7.5" square. Screwed bowl on, concentric..........

Then screwed to faceplate.......

Faceplate in r/t chuck, and 2mm endmill..............

No problem! Then opened out to size.......

The square backing ply, rested on the machine table holding against rotating. While opening out the doorway.......

The corners locked into the T slot. For the rear vents.......

Rear view......

Front view.......

Made myself a start up burner.
Nub end of 3/4” brass. Opened out to 12mm x 1/2” deep. Stuffed with wick, will hold enough meths to burn for 2 mins or so. Then swap to tealight.

Now, need to experiment to find the optimum candle height......

That was cleaver Dave:-it didn't come out as a dogs dinner

When you hand the board vertical what was it clamped to, from the pic it looked like you were using sky hooks

Thanks Stew!

I was a bit pleased.... No distemper, or hard pad. The whole job went much better than expected. (Very thin stainless spinning).

Sky hooks? Nah! Not even a short leash......

I have a tilting r/t. Faceplate boss, gripped in chuck jaws. Just angled it over, until the ply edge, or corner, rested on the machine table.
I could then take off, and re set to position, as often as needed......

TWO candles!

Steady on!

Nomate, not just yet. The bowl was a little deeper than I wished. (This thing is growing higher by the week!). Still needs a base board.

The candle needs to be held on a plinth, some 3/4" high. Just making do, so far, with a spent holder and a jam jar lid.

The higher skirt/ deeper bowl, will allow me to make up a meths burner. Sometime...... Mebbe......

OK, we'll believe you!

Going OT : at least you're not (yet?) in the (Two Ronnies) confusing territory of needing 4 candles !

Very clever.

Hi David, very ingenious design of the stand, very effective means of cutting out and getting things in line. I keep considering a slot in the wick tube of a burner, and a small gear with a stem to wind the wick up and down, but haven't got to it yet, still moving the burner around to keep my engines running evenly. I took apart one of those fireplace lighters, with the long snout and the pietzo and found it has a good size reservoir and is refillable, and hope to put it on one of my flame suckers, with the lever on the reservoir to adjust the flame, with a simple burner head, and finding a place for the piezo to go. The alcohol works so well, but it is a bit finicky about adjusting and getting it just right. I'm looking forward to the finished product, burner, pan, all happily tied together.

Very nice indeed

Cheers, mad jack

Stilldrillin · « **Reply #95 on:** November 08, 2011, 06:42:14 AM »

Thank you all, for your continuing positive comments, Chaps. They're all, very much appreciated!

I found some nice, 8" x 11" rubber wood chopping boards, in a local shop.

Bought a spare, for later.....

Hacked it roughly to round..... Then fixed to the faceplate/ rotary table set up, as before.

Roughed it to 7" diameter using a 12mm endmill.......

Squeezed it onto the lathe, and radiused/ sanded the o/d.......

Spot of varnish........

This thing is getting BIG. Fifteen inches overall height, now.......

Workshop time is non existent, at the moment. The end is so near, and yet so far......

I only need to make the candle holder to "finish".......
