| Fantastic work Chuck, it looks amazingly good! I like the drip tray... I've made a couple of those for my engines and it certainly makes the run less messy. |

Really nice work. I mean really nice.
I am thinking of trying Reid's bushing idea to reduce some of the mess the 21 makes.  YUCK!!!

Hi, I have been reading this thread with interest as making my own engine from scratch is something I am keen on trying. I have hand made small engine assemblies before but not making my own boiler.
One thing I will try is using brass welch plugs (freeze plugs) for the boiler end caps. There is a picture of them below.
They come in standard sizes and are brass of course. You can get them easily from any car parts shop.
This isn't my own idea I must add. I saw it just recently in a local magazine we get down here and had one of those of 'how bloody obvious' moments! Sorry if this is already well known but I thought it was brilliant!
Simon

Hi Simon.
We have talked about using welsh plugs for boiler ends and I think someone here may of tried it. As long as you can get brass tube to fit the plugs its a great way to go that would save you a lot of work.

I would have been surprised if it hadn't come up before.
This is the magazine it is in. http://www.theshedmag.co.nz/
It's a good magazine all about people making interesting stuff. I did a few articles for them so now they send me free copies 
Part 1 of the steam engine story is just about the boiler. They used copper sink pipe apparently. Oh, and the safety valve has a ball bearing and a spring on the outside of the boiler.
Part 2 won't be out for a couple of months.

With my brother building his scratch built engine, he used copper pipe as the boiler, with soldered end plates, rather than caps.
With my recent finding of Dezincification, I'd prefer copper unless you knew the zinc content of the brass you use.
Other good parts to use are gasfitting parts, esp for taps/throttles.
Bathroom fittings like handrails/toilet roll holders, for brass chimneys/engine frame brackets
I know I've put it up before, sorry i can't find static picture of his engine at the moment, but this one is made from such parts mentioned above.
Also, gal steel for firebox, but burn the gall off outdoors first
Releif valve is from a hot water system. And yes, the engine frame are brackets from toilet roll holders
And the parts he made for his Bing vertical engine below. Only specialised tool he used was a flaring tool
|
How did he make the whistle, spoked flywheels and cylinder? I've been thinking of doing a scratchbuild myself, a double-acting Uniflow with poppet valves.

I talked to him probably 6 or 7 months ago and it sounded like the economy was hitting him hard, real nice person to talk to. I bought his Luton Bowman PW203 and his SE3

While I have no idea what poppet valves are, I am guessing that would be beyond my brothers skills and machines available to him.
I think the whistle was made from brass rod. Drilled, grinded, cut etc.
I'm sure the cylinder was also Brass Rod, drilled out.
The flywheel on his scratchbuilt engine has a wooden rim (later fitted with a brass ring) and used brass bolts as spokes.
As for the Bing flywheel, I would have to check, but I think the spokes were brass rod, filed.
