Oh dear PD's........it is good that we can post without fear of 

mogogear.... that PURPLE stained wood is very bright

No worries Derek..I didn't stain it - it is the natural color of the wood and I think when you see it after it is darkened by varnish it will deepen  and the color should be easier on your eyes.......

DEREK,

Does this put your mind at ease The purple wood now is stained with mahogany stain and a coat of polyurethane

New bands and mounted on the plate- Lots of superstructure work about to be to photo stage

Hi Greg,
I think Derek must be standing on his head or suffering from celebrating Australia Day.
I think it looks fine.
Regards,
Gerald.

My dear Derek- No offense was taken on this end- I have thicker skin that that - you and the others are most helpful and supportive.

The goofy hobby shop near by failed to have mahogany- but had exotic stuff?? I found that amusing

I just needed hard wood in strips the size I wanted!

Here is a quick mock up of the exhaust piping I am adding





Port holes coming soon and some roofing

Sounds like my local model shop keeper, i don't think he can pronounce expensive and uses exotic in it's place ...

I had a quick look at your web site this morning very interesting! ...

Look forward to reading more.

I bought some sheets of walnut recently and talk about exotic......they carry a 'made in China' label!!!

Hi PD's.....  .....& just to get back on the original build thread.......

mo...... have you considered the required breathing for the gas fired boiler?

I see the open door just AFT of the paddle box & a few MOUTHED vents facing FWD...& the mesh horizontal plates AFT of the chimney stack

Will this provide an adaquate air draft for the boiler? .....  ...... Derek

[mogogear]

Great question Derek,

Shooting from the hip... ..........  I think I do.

The two rear grated openings are 2" x 1"
Two doors are 2" x 1"
Two side clerestory openings made from ladder stock emulating louvered openings
each .75" x 4"

That feels sufficient...

Talking with a few mates... ...over a few about heat transfer

Like most things in life containing a lot of hot air  ...heat will build up & it's no good & won't go away unless you can move it

May be worth considering a low voltage computer fan to draw in air to create a pressure difference & thus expelling the hot air........however placement is critical to obtain the draft or air flow.....

Two methods here 

1. use the fan to create a higher pressure = push the hot air out
2. use the fan fo create a lower pressure = suck the hot air out

May sound  crazy..... , but either will work.............Derek

[mogogear]

Good points.... Fan noted...should be easy  to run off batteries for lights..

.Hmmmmmm, I should be able to find a small one

[mogogear]

Last thought on the fan while I shop for a small low speed DC model   - I should use it to draw cool air in so it does not sit in hot air the whole time-

I knocked out a quick condenser and have been collecting fittings , valves , attenuators and many little fiddly bits pepping for the plumbing session with the boiler, pump, attenuator , gas supply line and the engine.

Here is my condenser -What it was - label stripped off-  and what it ended up like-

 Yep tin can- yep it may rust our some day..but at a cost of about $2 for some brass sheet cut in to bands and a few brass nuts and screws- the price is right. I think oily gunky water may give it a decent life of a few years

Hi PD's..... ...I think we would all agree that Mo has turned an elephants ear into a silk purse    ...& that's just what it will do....cool that steam

Nearly as adventive as our UK colleague RGY  .......keep up the good work....Derek

I  looked at the photo and thought the label on the can said Orgasmic Tomato Paste - I really Must take more water with it!
