this is what NASA calls a stick slip. It sticks- then slips, then stick - then slips. and it appears as it moves.
I build several types- only to end up demonstrating the beauty of physics (the better they get- the less stick-slip)
Physics will NEVER allow you to Take something that it have said it shall have back..
It will help your equations if you multiply the formulas with TIME.
"Much force" x "short time" = "less force" x "long time" = 0
But I know. We still got to try...
:O)

Try doing this over a teflon sheet.
Think about the validity of the motion of this system if one of the walls of this machine was bombarded by metal projectiles in one direction. Then think what is different between that and the rotating projectile. I think as it strikes one extreme

This is the same as moving yourself on a skateboard without touching the ground. You push fast in one direction and slow in the other. In one case you overcome friction in the other you don't so you move. In space this wouldn’t do anything.

@mikeypnz Good thinking though, are you interested in theories about time?

@mikeypnz : ) np. The deadheadz do p me off a bit. Sometimes I wanna get the flea spray on em.
Look. Here's how science works. Everything starts out as magic. Some magic stays magic and other magic becomes science. Faraday's wire and magnet would have been seen as magic until everyone got used to the idea and someone blurted out some maths and a comfortingly waffly explanation to describe it. Assuming there isn't a hidden fishing line ; ) did you try mounting it on wheels?
F=MA but F is still broken down to it's components when absorbed into another mass. It moves across the carpet because A is a function of time and when the Force is absorbed abruptly all of the momentum is absorbed at once and the object is able to overcome the friction in that direction.
If this was a frictionless spacecraft in space the forces would cancel each other and no additive forward motion would result.

@1965ace I have since realized this also. An equal negative force is created but is distributed over a longer time than the quick snap so in a vacuum all forces will cancel. I was hoping this was not true! Probably the best explanation so far, cheers.

Deadheads: Ask yourself one question: Does it move or does it not? The answer to that question is all you need. Same with Faraday with his wire and magnet, you don't need to understand why it moves, you just need to understand that it moves.
Mikey: worry about asymmetric angular momentum creating a force imbalance later on; or better still let someone else work all that stuff out while you explore ever better ways of producing the effect. The deadheads will soon be paying your wages : )

@GMANIM haha cheers mate but i think they might have me on this 1. It's a little naive to say you don't need to understand why it moves - kinda defines the difference between science and magic. Appreciate the support tho. Peace
