lubrication:
The reduction of friction/heat in moving metal parts is what I evaluated next. Many of the products make claims in regards to lubrication meaning a reduction in friction/heat/wear. (some make fantastic claims) To evaluate lubrication claims I will evaluate static friction forces. If you slept through your science/physics classes, Static Friction is the force that resists the movement of two objects against one another when the objects are initially at rest. To evaluate the lubrication claims I made a simple device to evaluate static friction forces. Two polished steel surfaces are used to mimic firearms parts. Its size and length of travel was meant to mimic the travel of the action of your typical firearm. A force is applied to cause the weighted steel sled to begin moving on a steel track. Increasing amounts of water are added to a container that is tethered to the weighted sled until the weight is great enough to overcome friction and move the sled. The weight of that water will be recorded to establish a factor compared to dry steel against dry steel.
To establish a baseline value for two dry steel surfaces, the exercise was repeated 8 times and then an average was established. Each product will be evaluated by applying the product to both surfaces and recording the amount of weight (force) required to get the weighted sled to move and then repeating the exercise 8 times to arrive at an average force.
Here are a few photos of the device used to capture static friction forces.
Here is a brief video of the device in action. (note that in an effort to make the video as short as possible I poured the water faster then I will during the actual evaluation)
