The gauge needs some tweaks....
Hopefully the info in the video is still useful.
Also, my home brew dual cam mounts don't look like they moved at all. I assume that these turn tests put them near the max propensity to want to slide back and forth?
The videos are extremely informative.
Thank you very much for taking the time to conduct the experiment and make the recordings.
I had envisioned having the wand and gauge on the outside of the cam lift link, but I realize that would make photography very difficult.
Would you be able to turn the link so the u-bolt nuts are on the outside instead of the inside?
If you can figure out how to keep the gauge from hanging up on the u-bolt nuts and keep the wand from hanging up on the u-bolt nuts, chain links, and body parts, we'll be able to quantify the amount of bar tip deflection.
You also could measure a bar's load-deflection relationship by using the tongue jack to raise the tongue until the bar has zero load. Then unhook the lift chain and let your Sherline scale support the bar tip. As you raise the jack to transfer bar load to the scale, the bar will deflect. That will allow you to get load-deflection data.
Thanks again for setting up a great experiment.
