I am sure you know that the moisture causing the rust may be that in the atmosphere in your shop...40%...60%. Cool the air and it will come out to meet you.
Sorry, just had to mention it.

Future food for thought : Many foods and electronics products come with silicon desiccant packets (do not eat) -- the sole purpose of these is to trap moisture in the packaging and prevent it from spoiling the food/ruining the product.

If you see any of these in something you buy, immediately after opening the product, put the silicon desiccant packet in an air tight container for later use. You can gather a few of these and put them in an air tight container with anything you wish dried out or kept dry, and it will suck all the moisture out of the air (allowing moisture on the parts to evaporate, thus being sucked up, etc)

Another product that I've used to remove high amounts of humidity from the air is designed for damp rooms or closets, called Damp-Rid, available just about anywhere (supermarkets, walmarts, home depot, etc) and it comes in various types of packaging for various purposes. It would work in a similar situation - place your parts-to-be-kept-dry and a package or two of Damp-Rid in a closed container and let it do its magic.

I live in a very high-humidity locale, and have to deal with humidity in a variety of ways - I have a dehumidifier running 4 hours a day in my master bedroom (it gets up to 85% in there by morning), and have used damp-rid in a number of other situations. I also always place silicon desiccants in my lockboxes and things that hold important papers, to keep moisture from ruining them.

Mosey, Ryanath.
Thanks for the thoughts. It isn't a humidity problem. I think!  :thinking:

I'm in the same room as the toy cupboard. The humidity's 42%, and temp 21c.

Hi Dave.
I've never heard of Drygas!  :shrug:

The engine is stored in a dry, household cupboard.
The air supply is from a fish tank aerator pump. Just a gentle air flow, for a few days. Many of the Steamtoy Lads do the same, to dry out their boilers.

Rather disappointed, the Bluecol allowed rust to form.......  :-\


Hi Frazer.
The Bluecol is the top up mixture. Ready to use.

She's been dry. Hiding in the airing cupboard, for 2 years! After the last run.......


Yay! Well done, getting a runner!  :whoohoo:

David D

 :lolb:

OK you live on a continent that rains more than it shines...and no drygas!...
It's at any service station here....about a dollar a bottle...pop one in when you fill up.

I like the shellac idea...but don't put any alcohol in there after!

Dave   :cheers:

Made a little headway.

Spent a lot of time filing and fitting together. Cleaning out threaded holes, and shortening new screws to fit.

Painted some parts........





Not happy with the deck surfaces. So, will scrape off, and re paint.  :(

Didn't like the pifflin' 3/16"dia. m/s crankshaft, holding a 4.5" dia. cast iron flywheel.   :ShakeHead:

So, I replaced with 6mm silver steel, and new bushes......




In real life, these engines were usually located in the scullery, to supply water from the well, to an in house storage tank.

Does anyone know what kind of pump would be used?

Thanks Stew!
I'll be there, all being well.......  :whoohoo:


Slow, but steady progress.    :cartwheel:

I've sleeved the flywheel bosses back to a sensible diameter. Also, the bore to 6mm.
The colour's not as orange, as it seems here........




Lit a small burner, to cook the paint a little.....




Warmed gently for 5 mins or so........




Didn't want any paint blisters....... But it's a trier......




Finally coming together!  :D

Well done David  :ThumbsUp:

Looks like this is another orphan that's finally at home.

Kind regards, Arnold
Building an engine takes Patience, Planning, Preparation and Machining.
Procrastination is nearly the same, but it precludes machining.
Thus, an engine will only be built once the procrastination stops and the machining begins!

Thanks for your kind comments Chaps!


Today's temporary trial. No coolant. Borrowed the gas burner from the Huxtable.


    Oh..... Happy Day!!!!   :whoohoo:


<a href="http://www.youtube.com/watch?v=M4PUmj25vZg" target="_blank">http://www.youtube.com/watch?v=M4PUmj25vZg</a>


Now needs a coolant tank, and it's own gas heating system.

I've ordered a gas tank. Will have a go at making my own burner.   :ThumbsUp:
