I have reached the point where I need to add the finish to the barrels.  I did the RG G thing and put liners in the DOM tubing. I believe the outer tubes are chrome moly tubiing but I am not sure of the metalurgy. What is the opinion of this group in putting color on the barrels. I am avoiding the word "bluimg" but you guys know what I mean. My choices preclude hot bluing as the cost and inconvience of sending them somewhere is out of the question. There is a guy on YouTube who puts browing on warm barrels and then cold blues over that ( 5 or more coats of blue) and claims the corrosion resistance is multiple times that of just cold bluing. I am not sure if corrosion is a significant factor in the life of a .22Cal gat, but it is a factor.  Almost all of the pictures on this forum display beautifully colored barrels. What did you guys use?

. The barrels are cold blued with liquid oxpho-blue.
I have found that if the barrels are dipped in the oxpho-blue instead of rubbing it on, a nice even blueing will be the end result. A piece of 3/4 inch PVC pipe that is a couple of inches longer than the barrels with a cap glued on one end works great. Just hold the pvc pipe vertically in a vise and fill it about 2/3 full of oxpho-blue. Plug your barrels with wooden dowels on each end with one end longer for a handle to dip with.

Thank you for the info. Simple enough that even  I can follow with a minimal chance of screwing it up.

I will post some pix as soon as I figure out how I want to construct the frame. I have the materials cut, shaped etc but I am very uncomfortable with the extended U shaped configuration as shown on the print. Keeping in mind that my relative inexperience has in the past allowed me to smash anvils, I want to start the assembly build in a way that won't twist or otherwise mis-form the frame as I attempt to perform the necessary measurements to properly mount the box cam within the casing etc.
