Full steam ahead, SOON. Red paint just from the recycled materials.( tin tray)         P1 drilling the holes first. Then find the shape after.   
P2&3 steam drum completed, and fitted on plate, plate fitted to boiler. Geoff

P1. How I planed to make the manifold. I decided there was to much weight to high  . So have changed the design, by reducing the size, using tin plate for the top and sides. Insted of 1/16th plate as in the other photos. Geoff

ahhhh, now I see how it's going to work, brilliant 

Only brilliant if it works. Geoff

Hi Geoff
             Exeter model boat show  on farthers day are we going to see this beastie there oh and you of course.

Old man if I can I will, but not on the water I am afraid. geoff

Progressing with the manifold today. Soft solder & riveted joint? Will the solder  melt!! Lower joint will be drilled & tapped 8BA. Sliding door made of 1/16th plate. Runners to be fitted. Next a plate over the front to hold the steam drum securely so the water gauge won't snap. Geoff

I did wonder about that as the heat from the furnaces is collected inside the 'coffin' without water to keep the temp at around 100c, would it need to be welded?

Yes Mick, I sure you are right. Especially as I will be covering the lot in soldering mat & cooking foil.
The disadvantage of a twin boiler set up is the extra outer surface area. I shall be running it on the bench first. So when the solder runs out I shall push fire cement back in its place. Yes I should have silver soldered in the first place. I was having trouble holding the joints in place ( to drill for the rivets)that is my excuse. Geoff

Making a pattern for the front plate. Using the brass rubbing technique.  In the photo the bush holes look lopsided, well I am afraid they are, a consequence of dropping the boiler in an annealed state. The boiler that is not me.  Geoff

Hi PD's....& RGY says......... "The boiler that is not me"   


We are always watching .......... ......Derek

Good job you couldn't see me the weekend Derek.  I was well anneled. Geoff

Geoff-- superb sheet metal work-I sure like your ideas!

Greg, coming from someone of your caliber I take that as a really good compliment. Unfortunately the sheet metal work looks better in the post than it does on my bench. It will be better when finaly fitted in the Duke. thanks Geoff

Someone once said (probably Derek) there are no problems only solutions.  Well there was a problem with the tin-mans solder melting in the manifold. The solution was found in a builders merchants catalog. Woven glass soldering mat & glue to stick it, both guaranteed to withstand 600 degrees. So the inside of the manifold will be lagged. Insulating the manifold & preserving the solder.
