So I decided that I should build a boiler for my D10....
Getting material was difficult, however I had some luck with local plumbing supplies shop, they had a piece of 4 inch tube and I got it free of charge.
2 inch 16 gauge was totally different story, I ended up buying it from Maccsteam.
Sounds a bit ridiculous but it is true, had to buy a piece of copper tube from half a planet away.
I do not have drawings for this boiler, I'm basically "freestyling"

Forming the endcaps was straight forward, two timber blocks, oxy set and a lot of patience, just keep annealing the part as soon as it starts ringing when you hit it with a hammer.
Anyway, have look at the photos, any advice is welcome

From the looks of it you do not need any advise.

Thanks Gerald,

I can find my way around workshop easily , but I also believe that all people know everything, single person does not.
Is there any rule for smokestack size ? I intend to use 32 mm dia. tube.
Entire boiler will be 290mm long, am I overdoing things here ?

Regards
Zelko

Hi.
Most of the boilers I have seen have a flue that is smaller than the fire tube , I would guess by about a third. Not sure why , but I am guessing it is an attempt to get all that nice heat to stay in a little longer.
Don't forget to use higher melting point rods for the burner tube and slightly lower for the ends, like I didn't first time round and had silver solder melting all over the place
Nice engine by the way.

Still making progress, just finding it difficult to find free time.
Anyway, I managed to silver solder the boiler. Everything went quite well...
I drilled and tapped only one journal, that way there is no extra holes to plug for pressure testing.
And, I have to bore a hole for a chimney/smokestack/funnel.
