New vise test request

2

I have watched all the videos of the hardtail vises, i think these are a neat bit of kit that genuinely out perform other brands in all aspects. It is easy to tell that a lot of thought and consideration has gone into designing both vises. You can tell when someone has genuine confidence in their product when they post videos about forcing them to breaking point and comparing them to leading competitors.

Im very curious about the tests that have been completed on these products, and i am writing to request another test. In the previous tests the vises have been pushed to the limits in order to show their calculated failure points, first the handle bending, then the tube nut cracking and so on.

The new test i would like to see is if the groves lathed into the handle (as calculated failure points) are actully neccessary. We would be able to test this by replacing the handle on the test subject vise with a solid bar of the same dimensions and material as the original handle but with one difference, there would be no lathed grooves in it. Then by putting a cheater bar on the handle and putting torque on it we would see weather it is the handle that bends or the tube nut that cracks first. This would prove if the lathed grooves are neccessary.

If this test couls be incorporated into an upcoming vise testing video i would be grateful.

Thanks

This is covered in the later half of the first video we did on the hardtail.

Im more thinking about proving if the grooves in the handle are necessary. You might be able to simpify the handle design to remove the grooves if a solid handle bends before the tube nut breaks. The comparison i would like to see is handle with grooves vs. Handle without grooves.

The handle protects the thrust bearings and screw and nut. Yes the grooves in the handle are necessary.
