What's So Hard About Going Up & Down? - Table Redesign 5

[@Vikingwerk]

Your commitment to figuring this out on your own, and not just copying the Fletcher table is what impresses me the most.

Thanks, I'm definitely investing the time.

I'm so excited that you're publishing videos on this again. I remember 8 years ago stumbling upon your videos and wanting to build one of these following your lessons learned. I haven't done it yet, but seeing you resume this gets me so excited about it again. I hope you're patenting your findings and will release a kit to use at some point too (it sounds like you're thinking of how to make it into a product already). If so, I'd definitely be interested in purchasing and using it. These tables are incredible. The engineering, and thought you've put into this project is astounding. Keep up the amazing work!

Thank you, it's a lot of work so it's great when people enjoy.

Another potential benefit to the torque tubes is you could lift the panels from multiple points along the radius, eliminating some chance of them camming.

Good point.

bro i LIVE for this. i feel like im watching documentation of someones invention and creation which is SO valuable. best of luck and i hope the rest of the build is painless

I'm wondering if ramps are even needed. If your roller hits a vertical surface, it is forced to ride up the vertical surface while pivoting the torque tube assembly, and then riding on top of the adjoining horizontal surface, keeping your torque tube assembly rotated to keep your table surface at the proper height. Im a KISS (keep it stupid simple) guy. Why make a ramp if you only need a rectangular block? In my mind, you could end up with some binding depending on lengths of your torque arm. If the arm ends up perpendicular to the ramp angle, it may cause the table to lift without rotating torque tube and end up at an improper height (scenario is highly unlikely). I hope im making sense here, im struggling to explain whats going on in my mind for others to understand, wothout the ability to draw pictures. Just food for thought, I'm liking the project!

[@ScottRumschlag]

I've thought about that too. Some amount of ramp slope is needed because the lift is almost the same height as the diameter of the wheel. If it were smaller, maybe 1/4 or 1/3 the diameter you could get away with a step change.

Hi Scott: I think that I appreciate what you are trying to do with torque tubes in that you generate lift of the star and pickets from a center point of the design, by torquing a pipe that telegraphs its rotation to the table's perimeter (times 4 in your case), no different than controlling the surfaces in aeronautics of an airplane's wing. In light of this, if you haven't done so, I think you might benefit from taking a look here kzbin.info/www/bejne/gmbaYmmNqbeEZ6ssi=Enxb2M4Vi2yRojRI&t=309 and applying your torque tubes' lifting forces to what this linked KZbinr calls a "lifting plate:" a device that (times 4) sits below the star and elevates it 2 table leaf thicknesses in height, grabbing at the 1/2 way point in its vertical travel, the "picket" as well--even if the linked KZbinr effects same with ramps that reside distal to the table's center dissimilar from your desire for centralized control of such lifting.
