Spirit cup for Tilley 246

I have few 246's but only two pre-heating torches. Pre-heating torches are not so easy to get here so I decided to make semi-permanent spirit cup to vaporizer tube's lower end. I made it from 1" brass pipe cap and hexagonal brass bar. Here are few photos from it:



It fits quite ok to vaporizer tube:


I just need to test how it works...

I believe that somebody else has made similar thing earlier.

 

Nice! The cup from a Vapalux will fit - and gives a similar effect.

 

That looks good and should withstand an Atomic blast!

 

I have not seen Vapalux lanters since they are not very common here so I have not seen Vapalux spirit cup. Thank's for that info.

Yes, it's heavy duty spirit cup. Minimum material thickness is more than 1,5 mm of brass in both parts.

 

G,,day . a piece of fibreglass rope glued in the cup helps them .
I use the glue / cement that is used on wood fire doors .

cheers,

Finally I had a change to test the spirit cup. I put some kevlar rope into it to hold the spirit. It worked without piece of rope but with piece of rope hot/boiling spirit is not shooting small spirit drops inside of glass globe:


Test on metal grill:


Small flame inside of lamp:


Preheating almost done:

 

Nice. Seems to Work perfect. Good Photos taken. Can kevlar not burn

Maybe it's actually class fiber rope. It's rope that is used in fire place doors and sauna stove hatches for sealing.

I would think that kevlar can stand some heat since some welder's mitten and F1 driver fire protection suits are made of kevlar.

 

I use it as fencingclothing and that must only be washed on 40 celsius

Maybe with water it cannot stand more than 40 °C.

Here http://www2.dupont.com/Kevlar/en_US/assets/downloads/KEVLAR_Technical_Guide.pdf on page II7 they say that "Kevlar does not melt it decomposes 427°C-482°C temperatures" When you are fencing you need to keep temperatures under that limit otherwise your suit will start to decompose.

I would think that when the Kevlar heats up enough and gets flame/spark it will start to burn.

So most probably my rope is glass fiber rope...

 

First version of the spirit cup was sitting quite close to glass so I made two new spirit cups with shorter stem under the cup. One (on right) I made as first one second (on left) I made from shorter pipe cap and I left thread to the pieces (that saves some work since I am little bit lazy guy )




I'll need to test how they work with my Tilleys.
