With all the small parts finished, I can move onto the receiver and barrel. I put naval jelly and the receiver in a gallon sized ziploc bag for 2 hours. Im impressed with its ability to remove all corrosion. Then it was the same regimen used on the small parts all the way up to polishing.
It cleaned up well but I did a lot of extra polishing work.
Here is a short video of how it looks just prior to cold bluing.
Here it is after being cold blued 3 times.
The receiver will be coated with Brownells baking lacquer colored stainless steel grey to mimic the metallic look the gun had originally.
Then it was onto the barrel. Earlier in the process while I had the ATF and Acetone solution in use, I soaked the barrel in order to remove the attached parts. I also used the solution in the bore with a copper brush. What came out of the bore looked like crude oil. I worked that brush through the barrel many many times.
While working the receiver I soaked one end of the barrel in the naval jelly. My container was too large (or I didn’t have enough naval jelly) so I threw some wood strips in to raise the level of the jelly. After 2 hours I pulled it out and rinsed it under hot water and dried it and only gave it a brushing with a stiff stainless steel bristled brush and then steel wool to remove the powdery grey surface created by the naval jelly.
The effects are pretty noticeable. Here is a video showing how well it worked.
After 6 years, (and lots of projects) my Dremmel tool died. Off to the store for another.
While I was out buying another Dremmel tool I picked up two more containers of naval jelly so I could remove the rust from the entire barrel. I cut in half a plastic tube that paper comes on for our plotter at work. This tube bathtub worked pretty well once I plugged the ends with foam and tywraps.
After 2 hours I pulled it out and rinsed it under hot water and dried it. Here it is with the powdery grey film left by the naval jelly.
Then the wire brush and steel wool treatment.
After 3 applications of Dicropan cold blue.
The next step is applying the Brownells baking lacquer.
