Update on the two outdoors corrosion boards. Hornady One shot has finally failed on Board #2 Leaving Frog Lube and WD 40 Specialist but the Hornady product is still going strong on board #1.

Well at this point I think that the 3 are still doing well. even with the one failure..A long time in the wet wonderful out of doors..It ain't real wet here though..Going to a gun show this weekend..There is a guy at this one that sells all kinds of gun lubs etc..some I have never heard of.

I am in the process of designing an experiment, process and device to do further lubricity evaluations on these products. The first evaluation was for the coefficient of “static” friction but I fear it was lacking (even though it was a reasonable side by side evaluation) so Im working on evaluating “dynamic” friction forces. The long holiday weekend should provide me with time to get this going.

Static coefficient of friction was pretty straight forward with the weighted sled and the addition of water to eventually break free the friction forces between the two metal plates but I am devising a constant motion evaluation so I can capture the friction forces between two metal plates that are continually moving to gauge lubricity of the products as well as wear over a great duration than the static friction evaluation.

Ive completed the device I assembled and plan to use to measure dynamic friction forces. There are some refinements I need to make but I think the concept is pretty straight forward.

Here is a video of the dynamic coefficient of friction device in action. Its clear I need to work on the consistency of the smoothness of the big saw blade. You can hear and see the variations in smoothness.

In the coming days I will evaluate the friction reducing properties of the products I have previously evaluated for lubricity and corrosion resistance.

That's a really impressive bit of engineering!

Amazing!
 

I am impressed. Well done and very ingenious. All the best...

Heck I'm very impressed, and as usual I can't wait to see the results.

Rather than posting the day of the failure on the thumbprint portion of the indoor plates I have waited to lump the recent failures into a single post. Here they are. Again this is only in the thumb print area of the plate.

As for the outdoor boards. Board #2 has now had every product show corrosion at 29 days. Board #1 is at 30 days with the same remaining products still fighting off corrosion.

Thanks for your time and effort on this project and well done Rancid, appreciated and very informative.

If you ever have ambitions to do another test including additional products, I'd recommend you include Prolix.

Thank you for all you do to help us here at HC. I am very impressed with your work.

Here is an update on the corrosion boards after 43 and 42 days outside.

The last three samples on board #1 are about to give up.

Board #2 samples are all finished. Every sample is showing corrosion.

The indoor samples (after 41 days) are showing more failures. (Only in the thumb print area)

Rust prevent, WD 40 regular), Militech1, Strike hold, Archoil, 3 In One iol, Kroil, Hoppe's MDL. Mil Poro 7 have now failed along with the others that had failed earlier.

As mentioned earlier I put together a device to capture the dynamic coefficient of friction for all the products I have previously evaluated (including a static friction evaluation)

Ive tabulated the results and they are similar to those of the static coefficient of friction evaluation.

Here is a video showing how the evaluation was conducted and how excess lube actually worsens or confounds our attempts to make metal slide easier against one another. The video will show that only in the absolute minimalist state do the gun lubes actually reduce the friction/drag forces.

All the products were run through the friction device and the chart below shows how each product performed in comparison to one another as well as dry steel (no lube at all)
