I Have a Boiler. I need to finish it.and having spent my allowance I decide to build 1
I have a 105 mm (4 inch) brass shell
the end has bee cut off for use in the flywheel of the Beam engine
after taking a hacksaw to the rest
I end up with 2 pieces both have been flattened out
both have now been annealed via the inbuilt fireplace that we are using at the moment
I have started to bend the ends over in readiness to join up
to make my desired size
the other flat pieces will be sufficient to get my end plates I hope

I have 2 more shell in my shed and I intend to build a vertical engine along the lines of a Scorpion but as kiwi's are better i will build it bigger !! I have already sourced a burner (brass) which will hold about 250 mls meths!!  more photos coming tonight as got rained off this afternoon until milking time.so managed to get some more done
|

That burner will need a big boiler Dennis.

boiler joined and soldered along main seam
end cap stage 1
I turned 2 wooden discs to hold the endplate between in the vice and proceeded to start tapping it over
and ended up with this
after annealing it repeat process
then into the lathe to square up
|
Scorpion2nz
|
finished part
and blow me over it fits
I was surprised it was so easy as I am working with 2mm thick brass
the boiler is 70mm diameter and 150 mm long

Excelent Den................I like this thread

I have been busy making bits for the boiler and here they are
now this will have you all thinking 
|
Spokesmann
|
How big is it Dennis. Things seem to be proceeding well.
|
Scorpion2nz
|
diameter about 70 mm and length 150 mm and now i think it may be to big for my beam engine .  . So may have to make a smaller one (boiler) and then make a bigger engine for this boiler
|
Mamod Collector
|
Hard to think that used to be a gun shell, excelent workmanship Den
|
Scorpion2nz
|
all the bushes in place and solder with silver solder
and end view of the chimney
also silver soldered
and here we have
completed
I did soft solder the ends on
and I have tested it to 40 lbs a square inch I only had 1 leak
and that was the chimney at the top of the boiler 
I can not test any higher than that as compressor not strong enough
so may have to make another adapter so I can use the one at work

Looking very tidy Dennis, should be more than sufficient for your needs.

I just quoted this to my wife and her reply is not repeatable here
to make it simple it starts with F and ends with F

It was worth a try Den

You make it look so easy. How about some video next time you're soldering?

Video while soldering
I had enough trouble find spare hands and trying to see what I was doing in side the boiler and you want me to video what I am doing 
is that with sound or with out  if with sound then I may have to provide you with ear plugs
|
Mamod Collector

You could always ask the wife to help Den
On second thourts, better not

Super job Dennis, nice one

Perhaps change the thread name to "I have a boiler!"...?

With sound please Dennis, otherwise it just wouldn't be authentic (we can add the bleeps).

I have progressed a little more .I now have a fire box
and a Safety valve
lots of muttering with this I broke 2 X 1.5mm drill bits
to give you some ides of size the shaft is 1.6mm diameter threaded with 9BA and the larger thread is 2 BA to fit the bushes in the boiler
I wanted to put brass eyelets around the firebox vents but only eyelets I can find are brass plated so tomorrows challenge is to make some dies so I can use my arbor press and make some in sheet brass

Progressing well dennis, i can see a few visial influences in there! Excellent work.

Coming together well - nice detail of the build.

well the weekend is finished and I have made some progress.
no brass eyelets as I can not find in my shed the steel I was going to use for Dies
but instead we have
a displacement oiler with flange fittings
a regulator with flange fittings
a closeup of the regulator with the flange fitting
one flange screws on top the regulator via 5/32 BSW
the bolts holding the 2 flanges together are 9BA (damn small)
this shows the incoming steam line into the oiler
I have used flanges to join the boiler to the engine so it can be unattached real easy with out having to unsolder joins
I have used flanges as my attempts to make olives and crox nuts was a disaster to say the least
the flanges are 12mm across the widest point and the copper pipe is 1/8th OD
please excuse the close ups as I can not get my camera (cheap) to do any better. I think I need to sell a steam engine and buy better camera
and to top it all off today
Other half look at the boiler and asks where is the flywheel

Great stuff and an interesting thread.
I must admit to having a chuckle about the 1.5mm drills .. Been there done that got the  bit stuck under my nail.
Try running your lathe at absolute full speed when drilling very small holes, a dab of tapping compound also helps stop those " oh sh1t moments"

Coming together well Dennis, great attention to detail. Like the Disp oiler...!
