A special section just for steam engines and boilers, as without these you may as well fit a sail.

Excellent , looking better than mine, however is not the steel mesh meant to support the blanket insulation and therefore be on the inside?

Mike.
Now I understand.
I just couldn’t see the purpose of fitting it where I did.
This is the trouble of doing everything by oneself in my shed.
Thank goodness for forums like this.
Will rectify in the morning.

Got it !
The mesh should be like this.
That makes sense.
Obvious really, but then we all have to learn at some point.
Thanks
Ian

I'm not sure that is quite what Mike meant either, I think what you have now will restrict tube cleaning, why not just a flat mesh to hold the blanket against the cover?

Which tubes are you referring to?
The steam and mud are only accessible by removing the back panel. Likewise for the down tunes.
The copper loops are accessible only by removing the front and top panels.
All panels are easy to access as the bolts are captive.
Very happy to have a flat mesh as suggested, but what would be the benefit?

Love learning, so this is fun.
Thanks
Ian

Having seen what collects around the copper loops I think you could glad of some more room round them when running and cleaning.

It does look good though.

I see what you mean, and to clean the copper loops most efficiently both front and back panels would have to come off. Which isn’t really a problem.
As it is at present, the back of the down pipes are sort of closed off by the insulation.
Is this likely to create a problem and should there be a free movement of hot air around the down pipes?
Thanks

The downcomers are intended for the cooler water to travel downward into the mud-drum, promoting good circulation. If they are exposed to the flue gasses ver much they become generating tubes, and the natural circulation in the boiler (and steam production) with be adversely affected. I'd even go to lengths of having insulation completely blocking the downcomers from any exposure to flue gasses.
