I regularly help out the members of the Steamtoy Forum by machining widgets for their engines.
One of the most needed components is a wickholder for SEL engines.
The originals were upset from 3/8” tube. I can`t do that........ But I can machine from solid......
Prototype. 3yrs ago......

On with the 2nd op......
Found I`d parted off all of them to within .004" oal. Not bad for an old `un, with a 6" rule...... :D
Turn locating dia to .003" interference.......
(http://i110.photobucket.com/albums/n95/Dayjo/P3230001-1.jpg)
Drill through to .050" short of breakthrough....... Remember, 9 turns tailstock handle.
Not much wall thickness left......
(http://i110.photobucket.com/albums/n95/Dayjo/P3220002-1.jpg)
3rd op. Drill 1mm dia breather holes.
(http://i110.photobucket.com/albums/n95/Dayjo/P3230013.jpg)
All done..... Time for a group shot!
(http://i110.photobucket.com/albums/n95/Dayjo/P3230016.jpg)

Thanks for the memories of a small firm`s employees, struggling 1972 - 79 Rob! :bang: :scratch:
CNC finally came along in 1985....... :thumbup:
We then just struggled a lot faster! :lol: :lol:

Sorry David, I didn't intend to stir up old memories :lol: :lol: :lol: :lol: :lol:
At our firm, the new employee's are given the real boring stood in one place drilling jobs, Most don't bother coming back after a week of it, The few that stuck at it, are still with us. I'm on my 12th year (I had a full head of hair when I started :scratch:)
CNC arrived in 2003, now I seem to spend my time standing watching parts being made through a little window :lol: :lol: :lol: :lol:

It`s nice to hear from a happy customer! :thumbup:
I recently received this pic, from Germany......

Most of my widgets leave me, never to be heard of again...... Sometimes, not even a thankyou! ::)
This made a very pleasant change. :)

Ahhhh! How curious .... just read all the way through this post, so what is the reason for the breather holes?
The reason I ask, is donkeys years ago I had some dealings with a hot air engine with a similar heat source. This used to flare up after some minutes use, because vapourised Meths was venting through the breather holes, and igniting. It was not my engine, the owner asked me to block the holes. I refused on the grounds that it would not stop the effect, just make the consequences worse. It was reduced by only about 1/5th filling the tank. By the time it got hot, it was empty. Hopefully.
Not a home made job, it was some commercial tinplate 'Mill Engine' thing. Don't remember who made it.
I surmise that these burners don't exhibit the same antics... or do they ?
Assuming they use Meths ..
These holes must either be to release any internal pressure, or to allow air in to replace used fuel. Can't see any other reason.
Hmmmmm... interesting ....
Where do you fill them ?? Can't see any filler cap.

Dave,
To fill, pull out the wick holder, as in 1st pic. It is a push fit in the tank.......
These meths burners are well known for flooding, when filled enthusiastically! But, with the tank 3/4 filled, all is usually ok. Most kids learned, before Mum spotted the scorch marks......
The vent holes are placed there so the gasses are ignited by the wick, when safely under the boiler.
There was an early (Japanese?) burner, filled & vented through the hollow handle, which flamed like a blowlamp when in use! Not really safe for kids to play with. They didn`t sell many...... ::)

The one I was involved in looked much like the centre one from German Pics. The filler cap was in bottom RH corner IIRC, wick about where furthest one is.
Not a hollow handle. Could have been Japanese tho. Dunno.
The burner did not seem to be from the engine. There were 4 pressed lugs, as if the 'proper ?' burner had a flat base, to slide into. Also seemed too high.
Anyway, went well after cleaning the carbonised oil off the piston rods.
Did Mamod or similar make them?
This one had a black base, and a 'Brick' painted and embossed smokestack wotsit. Can remember that bit. IIRC base would be about 9" square.

Dave,
That sounds like a Marklin, or maybe Bing, pre war hot air engine, with a non original burner........
They show up occasionally on Ebay.
There`s a couple of little pics on Google...... "hot air".......
My pal Roger had his dad`s, 55yrs ago....... Never seen one yet, that matches my memories of it.
Sounds as though "your" burner was getting too hot. Not ventilating properly, as it was too large for the space available.

If you go down this site to the 'Carette' pic. it was much like that, I'm pretty sure it was NOT actually one of that model, but in a general way it was configured like that. No Standards or line shaft. And the firebox was longer towards the RH, not so square. Burner went in from front.
Nice though, can see why folk get an affection for these things. :thumbup:
