The burner

More to the burner than meets the eye was going to make one using a copper end cap the ones i have are too small the next size too big so i more or less fabricated one was aiming to make one just holding 7mils as it turned out this one holds about 12mls far too big but i`m stuck with it. The wick holder you can see is longer than the tank i read somewhere that the fuel level in the tank should be below the level of the wick holder now when the tank is filled with 5mls of meths it does not reach half way i could see that when i was checking for leaks you could hardly see anything in the wick holder so i have really made a mistake regarding sizes. Now hears the rub with 5mls of meths it ran for 20mins YES 20mins and would like to hear from anyone who knows about burners why this should have happened the flame at first was large then at the end flame smaller but would still burn your hand

Fitting of the burner, attached to the platform by a threaded ring the two holes in the ring is so i can tighten it with a lens spanner

The other thing to watch out for is the spacing of the wick below the boiler dispite my mistake in sizing it looks not too bad the only other thing i have to do is to make an adaptor for the boiler outlet pipe i want it to run down vertical at 90degrees  and that should really take care of all things below the waterline.
Bit slow this month due birthdays,family visits, shopping and so on but still progress

As you can see the frame is only held on by 6 10ba screws

Only an idea it is now at the stage i could steam it up and see what happens but the real problem is the burner i cannot understand why it burns so long with only 5mls of meths can`t see a restriction but there is something not correct. Could be the wick holder is too long but truthfully i have no idea so really can`t give any further update until the problem is resolved was going to try some tests today but just to warm in the greenhouse, when i said it burns too long the initial flame is quite high then it peters out with the flame quite small really need to find an answer. Might be a clue in the background.

Just before posting THIS thread i thought i would just check it out with air it runs across my desk just like before would have felt stupid if it didn`t but it does and i`m really impressed little bit early to think of the final image but it`s always on my mind.  At the moment the burner is still my priority i can now tell different designs have different properties i know there are people out there who know about such things but i don`t please accept this is the first time i have done such a thing and my two priorities are the length of burn and it must be clean the first may be controlled by the amount of fuel i put in the tank or maybe not the dia. of the wick must play its part but you guy`s already know that.  Secondly it must be clean by that i mean a nice blue flame i think the "Holy Grail" when it comes to burners a candle flame only puts soot on your boilers. Working with meths during the daytime i find  hard to see the flame so need to find a way to darken the daylight maybe an upturned cardboard box which i don`t have but will need to think of something the following pics might interest some of you

So you see i have reached the "Holy Grail" if you have not seen a burner of this type with a blue flame you have now

I did a little tweak with the height of the wick and i can see a little difference in the flame this was done in the house just to get the pics and i thought  maybe enough in case things get out of hand.  Today is my Great grand daughters birthday so you know where i`m going tomorrow shopping so it will be the weekend before i can try out further trials. Will report further but i think i`m winning.

Frazer many thanks for both articles the second one is where i got the idea the man in question i don`t know his name but he in turn said that he found it in some Forum which one he does not say so i don`t claim it`s my idea what i`m using is a Bronze mesh wick and i will enjoy adjusting it over the weekend. Getting back to your" wee pie wagon " i think that would be a great challenge don`t know if i have such skills Ford made a "Paddy Wagon" (Police van )and has a very similar body shape but there are so many to choose from. What makes me happy this morning is someone is following the post .
Best regards

Fear not Ron, there are others following this thread too ....  myself, most definitely among them!

I'm finding your combination of design ahead and design as you go to be a very interesting and seemingly successful approach.

I most certainly like what I'm seeing, and have great hopes for you eventually achieving the vehicle of your original mock-up dreams.

Wherever you go ..... there you are!

Stoker many thanks for your kind words and to others who contribute did some more trials

Wick now raised 2mm now you can just see orange appearing at the tip don`t know if it make any difference to the heat output maybe someone can tell me ( have already written a reply but nothing happened must have pressed the wrong button)so i will be brief . This burner will run for 20mins with 5mls of meths no matter what i do which is really too long for what i want. Can anyone tell me how small can a burner/boiler be that will run for 5mins
