New Steel Boiler for under £200

Pressure tests concluded - one spirt aside a tube, and a very odd weep on a stay weld. The tube squirt went away after reheating the lot and throwing another £20 of silver solder at it and a quick grind and reweld around the stay sorted that. Holds 250psi all day now. I will post some pictures of it finished so some of you can tell me how the boiler tube spacing is all wrong!!

I don't like the colour,

its also avauilable in maroon!!!

Sorry Darling only in pink

Could not resist

I painted it for you...will be black eventually.

I hate to tell you this Fizzy, but that blanking plate is far too small

Hello Fizzy,

Fantastic work. What is the spec of the steel you are using?

Thanks, Carl.

Looks great

How close to budget did you get?

Looks like less than 500 quid

Was it a cheapo welding set you used?

Would you make the plans available?

I hope it steams as good as it looks!! I don't blame you for having a go yourself, that 2 year wait boils my water as well. I don't think my MIG is upto scratch for this kinda work but I might know someone who is.....

I learned a good deal from this post, thank you for taking the trouble.

My next question of course is why is there a two year wait? You would have thought someone would have jumped in to fill the void? But the fact is I know absolutely nothing about this but I would like to learn more.

Hi - I cant remember what grade of steel I used, but I am sure that it wasnt anything special. I did do my research and basic mild steel (I forget the spec - there are alot) is fine for this application, plenty strong enough!

I costed the whole thing at about £310. This was including £60 for a professional NTD cert. I didnh have to pay for the Tube as I have a friend who sells the stuff, and sorry but I can not pass his details on to you unless you want to buy £1000 of it!

It was a basic 150amp machinemart mig, but to be honest it was at its limit, only just going into spray. Im planning a 71/4 for Invicta so might try to source a better mig. Point to note is that you need to be very experienced to produce a good weld. The reassuring thing is that if you are anything less than up to the job it will simply leak like a sieve!

I will be happy to make the plans availible, if I can find them!

No doubt the armchair pundits will moan, complain and tell me that they are not correct........

I think you have done a great job.and yes there are far to many armchair pundits on the forum.i would be interested in knowing more re this project.first when do you plan to get a club test.and second.i have a 7 11/4 invicta and the old copper boiler is shot.over the past few weeks I have been asking re prices for a replacement boiler.copper comes in at just over 2500 pounds, a steel one at just over 1500 pounds.a invicta will never recover the price in a million years.so as an ex welder I can see a few weeks getting back in the grove and a new tig welder in the workshop.pleaee keep us all informed on updates, I am very interested and I sure many others are as well.michael

Hello,

Thanks for replying re the spec of the material. The armchair pundits will likely tell you that you have done it wrong. I suspect that there are a hard core of individuals who come on the forum purely for that reason.

Is this post dead, one of the most interesting on this forum for some time

It was already dead until someone posted here a few days ago.

I'm sure Fizzy will tell us of a successful hydraulic test etc. Ian S C
