Fellows,
I just checked the remaining can of paint I had left from the Hendey project which had the formula written on the lid with a sharpie. It's the same as shown in the third post. However the proportions of black and oliver green seem wrong. Based on what I can remember, I think I must have reversed these two when I wrote it down. It's hard to recall exactly 2 years after the fact but I'm pretty sure only one quart of black was involved. So It most likely should be 2 parts (quarts) oliver green to 1 part black.

This has been bugging me all day at work. Tonight I went out and mixed up two batches in baby food jars with the relative proportions of the 4 colors marked on the side. One batch was made with two parts black per the original posted recipe and the other with 2 parts Oliver green. The batch with 2 parts black does in fact match the lathe as well as some left over paint in the can from the project. The test batch with 2 parts green is too light and looks similar to army green. I jumped the gun when I saw this post and figured I must have screwed up because it did sound like too much black to me also.
The original recipe shown in the thread about my Hendey is correct. I removed the post from yesterday where I (wrongfully) corrected the formula.

On edit. I thought I would add that when I photographed the lathe, I used a lot of lighting in order to show the details. For any given picture I used from 3 to 5 halogen spot lamps either direct or reflected. I adjusted the photos to try to get the hue as close as possible to the true color. Everything in the photos is brighter than normal (notice how bright white the wall is in my Avatar) because there wouldn't be much to look at if I hadn't done it this way. In reality the color looks dark and smokey on a test card but when spread out over a big ol machine it does in fact look, similar to the photos.
A good many years after the fact

, but I just discovered Patrick Black's amazing thread this past week, thanks to Bill H:
Hendey 14 by 6 Tie-Bar Rehab
And thanks to Patrick Black and John Oder, for their work on the colors.
I wanted to share my experience with my attempt. One thing mentioned in a few posts was that depending on lighting and camera, as well as our own displays at home. . . Is that the color seems to vary in the many pics in the thread. All of them look so great, but maybe difficult to tell which tint is the exact color.
For me, my favorite of those, the color appears closer to "Olive Drab". And I am basing that how I see these two photos combined:
When I see the old Ford Model A's, I see "rock moss green" as this:
Also some Amazon lisings that happen to show rock moss green, and olive drab next to each other:
At the time the threads were written, Tractor Supply Co used a different vendor for its paint supply. Today they use a brand called Majic. I happen to love the Magik brand, over others for oil based enamel. While not a large variety of colors, what they have really lays down and applies nice, with real good finishes.
In attempting to duplicate I made a run to tractor supply. One bad news, Oliver Green and N.H. Yellow can only be purchased in 1 gallon, even online.
Just goofing around, and doing some experimenting, I had two new empty 1 gallon cans. I dumped 1 qt of black in each. Then I added one qt of O. Green to one. And .75 Light Ford Gray to the other. I wanted to see them individually before mixing them together.
What I found was the black had damn near consumed the colors. I was just a hair under total black for both, separately. There was no way, mixing them, and adding a little yellow was going to save it.
At this point I stopped, and started working with small samples. I found what works for me, and I truly think it is a wonderful color. But its based on the pics I've shown, and I think is closer to an "Olive Drab".
In this pic, the paint sample circled in yellow is the result of mixing as per original posted recipe, its appearance in real life with eyeballs is a hair shade less than black, or a super dark gray.
While the paint sample circled in red is the results of what I desired, and with my eyeballs looks something like Olive Drab.
Now because I initially started in two 1 gallon jugs. . .

. . . Well I had a dilemma, but it was an easy math problem. I kept going with both separately, and have two perfect gallons of the same color.
My recipe for that is Tractor Supply Co, Majic brand paint:
1 Qt Gloss Black 2994
1 Qt Light Ford Gray 2967
1.5 Qt Oliver Green 2974
.5 Qt New Holland Yellow 2952
For a quick sample, I'm going to paint a straight edge, and a section of a B & S surface grinder. I'll post pics on that in a few days.
