Looking for a Bearing part for a rotating section.

[Rakaydos]

I have an ambitious plan for a minmus mass driver, that requires a rotating bearing part.

Scott Manley used a module that would meet my needs during his Reusable Space Program youtube series, but I do not believe he actually identified the part or the mod it is from. (

)

I'm looking for a part that can freely rotate on one access, and attach additional parts to that rotating section. I would be interested in comparing different types of bearings, if more than one is available.

Specifically, I'm trying to build a horizontal mass driver for Minmus- hook up a kethane-filled fuel can, start it spinning, extend the winch(s), release the winch at maximum speed, and RCS the fuel can into a stable orbit. Or launch anything else, within the mass limits of the launcher.

he did identify it; it is the free rotating rotatron part from damned robotics. I think that part is now gone from the mod but it has been replaced by a free rotating docking washer. the part is a thin cylindrical piece in 3 sizes, 0.65m, 1.25m and 2.5m and it rotates freely (and cannot be locked).

Can I have a spaceport link? the only Damned robotics entry I could find hid all regular parts when I tried using it.

Infernal Robotics by Magic Smoke Industries has such a part. The mod has worked well for me.

Thank you.
