Lil big hualer saddle tank loco bash.

Organic compounds are the chief category of substances acting harshly upon lead, and Acetic acid is among the most destructive of these carbon compounds. Acetic acid acts upon lead and transforms it into lead carbonate which is the white, granular, powder we frequently see on lead ship model fittings. The museum objects conservation community has been aware of the phenomenon for several decades and the chemical process that causes it is well-understood.

The chemical process is: Acetic and some other acids, in the presence of carbon dioxide, catalyze with lead to produce lead acetate and lead hydroxide. Lead acetate and lead hydroxide together react with carbon dioxide and form lead carbonate. Lead carbonate then releases acetic acid and the process becomes self-sustaining. It is important to recognize that the formed lead carbonate is not just a substance clinging to the surface of a casting, it is the surface of the casting transformed to powder. For practical purposes, a portion of the lead is gone and lead carbonate is left in its place. The lead carbonate releases acetic acid which can continue the process until the lead part is progressively consumed from the outside.

Lead is a very interesting metal. In the 'good old days' paint was made from lead. Indeed, Yorkshire had the White Lead Paint Company. Lead was laid outside in Tenter fields to weather and the resulting carbonate was scraped off and collected.

To inhibit the decomposition process, Anti-Patination Oil was used - particularly on lead rooves. Also, red lead was used with putty to create a sealing compound and as a paint primer. I have used both in the past.

When handling lead, barrier cream is a useful (and essential) preventative. Gloves should be worn. When lead burning, don't breathe in the fumes!

And, when you have had to deliver rolls of lead as big as a carpet, you sort of get a feel for it (so to speak)!

I've handled many tons of lead in my life and seen the effect it can have on people's health.

I knew there could be a problem!
 
Worked on the lil hualer last night. Got the coal in the bunker. I don't want any more weight in the back so I cut a piece of styrofoam and hot glued black fish aquarium gravel to it and mounted it in the bunker. Looks ok . Wish I would have made the bunker bigger. Pics are a little dark sorry.IMG_20180227_231546416.jpg IMG_20180227_231542089.jpg IMG_20180227_233338876.jpg
 
Jack I like the look of the Forney you have created think maybe the stack is a little large in diameter but if any not much. I know you tried running the creation when it was an 0-4-0 but have you tried it as a 0-4-4. I know when I did my Forney that it had a fair amount of rear end overhang because the drive system was not articulated, enclosed is a pix of my rear truck suspension, shorter is better but if you are operating on 1500 or larger it's not a problem. Really like the looks of the engine, tankers are one of my favorites, Bill

sorry forgot, you might want to add a saddle water fill pipe from one saddle tank to the other and I would say probable where you took the bell off and it would hide the bell spot and give you a plausible water fill
 
Thanks for the comments Bill. I was debating the size of the stack then I found a video on YouTube and the saddle tank loco had pretty much the same stack so I thought I would just leave it that way. I took a screenshot of the video. I can't zoom in or it won't fit to upload. I like the picture you sent pretty much exactly what I have underneath. I wish I would have made the bunker longer but like you said the overhang would have been even more. Do you have any pictures of the piping to join the tanks? I like that idea. Thanks for the great comments . Hopefully the more I do stuff like this the better I will get. I strive to be as good as you and others on here. You guys are in a different league lol..

It's running as a 2-4-4 now. And so far so good...

Check out the 2-8-2 saddle tank engine in the forum, you can see it in between the first sand dome and the steam dome, Bill
