Touring Turm and Turm Sport. Overhaul and a little modification.

I once received these two Turms from @Nicola Francesco Elia . (Thanks a lot!)
I decided to do a review and a minor modification.
I first got down to Touring Turm.
It turned out that there were only remnants of the old wick in the fuel tube. I scraped them out.
In order to thoroughly clean the fuel system, I unscrewed the entire line. The tube supplying fuel that the tank is located on the right side and is sealed with graphite packing.
I cleaned everything and blew it out with compressed air.
The modification was that instead of a fiber wick, I made a filter/wick out of tightly coiled brass mesh.
A sizable supply of fine brass mesh, I once bought from an old mechanic who made filters out of it.

Just like in this EMES stove.
EMES
Understandably, such a net needs to be removed from time to time so that it can be cleaned. A simple way to do this is to screw in the screw that is used for drywall and just pull to remove the mesh.
This is the way I successfully use when maintaining a lipstick-type burner on the Primus 96.

I would still add that there is an interesting element in this stove, in the form of a safety valve, mounted in the filler cap.
This is a thing, unheard of in other gravity-fed spirit stoves.
Several years ago John @presscall deciphered this mechanism in this post. Turm Touring meths stove refurb.
I, just to confirm this, right theory, translated the indications appearing on the tank.

I did the same with Turm Sport

Here are a couple of photos.

@Knee great job! I have just received a big roll of fine brass mesh and I think I am going to apply this wick style to my stoves as well!

Glad you like them

Bukta Methex
Bukta Methex, early version
and one swedish
its all that type constructions?

 

Good work @Knee, a durable alternative wick with no negative impact on the performance judging by the photos. A very handsome pair of stoves.

 

Thanks guys.

I was attracted to this venture by the solutions used in this EMES stove.

I, too, have other gravity stoves and am considering using brass mesh.
The mesh needs to be rolled very tightly. I won't hide the fact that this is a highly frustrating task due to the elasticity of the material.

 

@Knee
Great work Stanislaw. Brass mesh adds to the options for a ‘wick’ - a bit of a misnomer I’ve always thought. Really, a substance to slow down fuel flow and aid vapourisation. That cream-coloured Punker I have with a bundle of brass rods caught me by surprise and broadened my view of what could serve other than fibre.

John.
Indeed. The term wick, in the case of this type of gravity stove, is not quite correct....
On the other hand, I don't really know what short term could be used instead:

 

I always thought those wicks were asbestos. Does anyone know if they are?

 

@Knee yes, I know how tedious is to roll a tight mesh, especially the fine mesh that is quite soft. I guess if not too tight the flame would pulsate, did you experience pulsation?

The first attempt at too loose a roll ended with this very phenomenon.
Hence these tips.
We learn from mistakes.

 

Yes, in fact on these stoves the wick is more a fuel brake than a vehicle for it

The perfect combination is obtained when the perfect brake is found, the right amount of alcohol for vaporization must arrive at the nozzle and at a certain speed…

 

wick is flow/pressure resistance used for flows limitation
then "hydrodynamic resistor" is better then "brake"

 

Don't, it will then get abbreviated to 'HDR' and all the cool kids will start using it

Combined restrictor and vaporiser... how about restrictoriser?

 

flow restrictor - limiter was invented ?
:{

 

Brakestrictor?

 

as a brake
activated by hand or classically by foot?

 

Old thread, but I just got to looking at one of these I got at an auction last year, come with instructions that call the "wick" a "filter" which should be cleaned or replaced when it clogs. Mine will get a candle flame where the control knob fits into stove, got some snooping to do. You can just barely see the candle flame in the lower part of picture, if anybody has any input I'm like a cornfield.........

 

Keith do you mean a flame like this?

 

Flame is at the control spindle, not under burner at all. in the picture you can barely see the blue flame in the lower corner of stove, as stove is turned up it gets pretty good sized. Going to pull it apart tonight . Saw @presscall had one all apart and it didn't see any packing there.
