HAPPY NEW YEAR TO EVERYBODY!
Dear you all!
Today I would like to introduce how to make Long Bar Clamp.
This clamp was built-in a quick clock, it make clamp can open and close very fast.
I hope you feel interesting in my video.
Please like, share and subscribe my channel to see more videos!
Thank you so much!
I would be careful about this one. I generally like the whole concept and especially the quick camming idea. However, there seems to be some license taken as to the accuracy of the video. At 11:51 slack is taken up with the cam. At 11:52 the sliding part of the cam slips. 11:53 the whole fixture slips. At this point (11:53) there is a slight discontinuity in the video (almost imperceptible like an edit) which is suspect about the overall clamping action. The right (thumb screw) clamps slips quite a bit as load is applied. However, that is fine as the thumb screw can simply be tightened as much as needed. But the camming side is relying only on the friction against a smooth tube and the canting (or cocking) action of its sleeve. I doubt it works as well as portrayed in the video. I like the whole concept but I would modify the camming clamp to have a positive mechanical stop. (e.g., Holes with pins, ratchets, dog lever, thumb screw, etc)
