COLUMBINE'S BOILER

[Robert Hornby]

Bloody hell - is there no respect these days. I brought my dished ends to show off to my darling wife and gave them to her as a valentines present. She said "ohh lovely - coasters"

Clearly another who should be banned from the kitchen.
Jo

Ah Jo you are far too quick to condemn 
 
Why? - I'm quite good at the culinary art and absolute ace at the washing up 

Ramon

Does that mean you will be cooking Sue a romantic dinner for this evening 

I was a little concerned about the idea of the pie filling pouring out of those central holes, it would be a devil of a job for washing up afterwards  I think that temporary use as glass coasters is a safer bet.

Nicely made coasters Robert!    And Sandy, thank you so much for your guidance!

Nice job Bob,
It makes me think of finding somebody with a hydraulic press for my next boiler, although you do get rid of a lot of frustration knocking 7- bells out of a lump of copper.!!! the only down side is that the neighbours get TEE'D off with the noise, so I have to do the hammering when they are all out at work, one of the advantages of being retired.

Incidentally, what gauge ( thickness ) of copper did you use for the end plates ?

George.

[Robert Hornby]

2mm George.

Hi Robert,

Well done my friend... and don't worry about the cooking references.
They do make rather good coasters though... perhaps a layer of felt on the bottom would help prevent furniture scratches

 

I was a little concerned about the idea of the pie filling pouring out of those central holes, it would be a devil of a job for washing up afterwards   I think that temporary use as glass coasters is a safer bet.

Jo

Jo..it is a male cooks method for letting the steam out... women make a hole in the TOP ... and anyway, Robert is in Australia and therefore upside down... does that count?

Keep happy.

Best regards.

Sandy.

I am thinking a little ahead of myself here but any thoughts out there in model land regarding the wood slats for my boiler? I made short ones for my drag saw engine but only around 40mm long and only about 10 of them. My new boiler will require slats 120mm long and around 60 or 70 of them.

Try the method I used on my E&A, they are about 100mm long and cylinder is 75mm dia

That looks good Jason; I'll give it a try. My "planks" will be 5mm wide x 3mm thick. I am putting some insulating cloth (1.5mm thick) between the copper shell and the slats that I had left over from insulating the Cobra exhausts where they pass close to the fuel tank and were heating the fuel up causing vaporisation problems.

Still following along Robert and with your pictures and descriptions and Sandy's help along the way also, this has been a great learning experience. For a lot of us boiler-making is a dark art so thanks for making it less so!!

After Sandy checked out my boiler plans I need to include 4 boiler stays. It would seem to be no problem for me EXCEPT  that I am having trouble in locating the 1/4" phosphor bronze rod from my usual suppliers here in NSW. (E J Winter, Model Engineering Supplies and Hobby Mechanics) Does anyone out there who could point me in the direction of said rod? I need 4 pieces 140mm long.

Robert, if all else fails, there is a company in Christchurch you could try,
  E- Mail          littlemetals@clear.net.nz
  Web site       www.littlemetals.co.nz

This company sells only non ferrous metals, brass, bronze, aluminium, and zinc.
I get metal there on the odd time that I buy any.      Ian S C

Many moons have passed since any significant progress made on the boiler but I can see a way clear to get back in the workshop. Sandy suggested I can use copper stays in lieu of bronze, so as I am able to procure that, I can move forward. In the meantime I have made the timber slats mainly in the mill and have lacquered them on one face and the edges. The ceramic tile holder was a simple bending and riveting job.
I have fully redrawn the drawings for the boiler to submit to my certifier for his comments as to design and construction. I have included the drawings here for, if nothing else, interest.
