    AN addition to what has already been posted. To get a right OD, turn a piece of AL to the needed size, put a counter sunk hole for a center. Now part off, then sand, f Ile, turn to size of the AL you turned
    .
    Used this I glass with a file, came out great

    Is there another combination that you can use to get a darker matte finish that is closer to black oxide?
    Or do you need sodium hydroxide and nitrates and hot tanks?

    I have collected all the (easy and cheap) components to try the method from this video that seems very good. One day I'll give it a try:

    Hey! Me too!! Looks like a simple process and the results in the video are pretty darn good.

    Great cold blacking video, it looks so simple. I wonder how the coating compares to the finish from hot blacking.
