Siphon nozzles are expensive

[Tony]

I used to have a collection of microwave transformers from my tesla coiling days, but sadly no more. I always wanted to rewind one for higher voltage output.

The trouble is that it's easy to rewind one for more current (very few turns) but impossible for more voltage (a great many turns).  For that it would really need a core that can be separated for winding purposes.

Danfoss make the ignition transformers for most kerosene burners.

They make your stock units, but they also make full duty units.  Again, i suspect, however, that they may be into special order paperwork, and the related costs : (

If you just download the danfoss pdfs the info is there.

Interesting.  This sort of thing?

I've got plenty of brake pipe to tinker with, so the Bernoulli effect may have to be played with!  Assuming my compressor can keep up with it, of course (that's the advantage of the Delavan nozzles, they're very efficient on air-flow.

I gave away my old Neon Sign Transformer, that would produce a decent arc between two bolts full time without any issues.  I'll ask the guy I gave it to if he ever got around to using it, maybe I can get it back

you could use a car ignition coil and drive it with a square wave. have a look at ignition coil teslacoils.

If you want an ignition coil and points off a central heating burner, I have one or maybe two, spare. If you want one, I'll send you one, no problem.

Appreciated Greasemonkey.  But I don't want to get too far ahead of myself with control systems - I'll start lighting it with the ol' blowtorch before getting carried away with fancy electronics

Besides which RM sold me a very fancy Rothenberger Super Fire 2 at the BBB and I want the excuse to use it! (Thanks RM, I love it - and that it burns upside down without flaring!)
