Metal-working panels on the International Harvester

                              Another day of metal working on the International Harvester. Using the hammer and dolly, I roughed out the worst sections of the panels that are currently sitting in the box. Once everyhting is as close as I can can get it by eye, I'll be able to bolt it up to check the alignment of each against its mounting point.






As well, I'm continuing to cover the rusted sections with Metal Ready 
in order to treat the rust that I won't be able to get at with the grinder:

International Harvester Metal Work - Rust Prep

A key ingredient to my metal work involves liberal amounts of POR15 Metal Prep (nee Metal Ready). It's expensive at $65.00 a gallon, but the chemical reaction the phosphate creates is like nothing else. It turns rust (Iron Oxide) into a black inert substrate (Ferric phosphate) that can be then primed and painted.


Eastwood sent me something similar to try, but it doesn't work as well I found....


So, with the "liquid-money" in a spray bottle, I doused the rustiest part with it. You're probably
 asking - why didn't you sand blaster that part? Reason being that it was rusted really thin 
around the one side and so we could either blow it apart with the sandblaster, or actually 
build it up by turning the rust into ferric oxide.


 After it dries, you can see the white phosphate that is left behind, doing it's work for days to come.



Lots of hammer and Dolly work is next:



Plus some cutting welding:


Everything that was just surface rusted was spared the abusive sand blaster  but will be treated with the Metal Prep.The Gallon will go quick on this project, but what better insurance?
