How was the spinning lightsaber blade made?

This shot from the movie, to me, proves they were square.

when i was a kid i always thought his saber was dying in this scene, and it needs a recharge

All interesting info. Either way, as long as they weren't round, I'm satisfied.

Three sides, four sides. I reckon the point is you can't get that effect with a round blade.

Exactly how I see it...

I used a square tapering wooden rod and an RC motor. It could do with a bit more torque as swinging too fast causes it to slow down.

Here are more details of my build:

If anyone identifies a more suitable motor I would love to upgrade.

Hi kurtyboy

any particular motor you used ?

where did you find a tapered square dowel ?

 

[kurtyboy]

The blade was custom made. I honestly can't remember the motor type, just the first one I picked up off the shelf in the RC store that would fit inside the tube and wasn't very expensive. But I would NOT recommend this motor so I'm not going to take the saber apart to find out what kind of motor not to use

[AMSW]

Understood - I'm sure I can find something suitable

custom made rod ? online ?

 

[kurtyboy]

No, the rod was tapered by hand.

 

[AMSW]

thank you kindly

What about an AEG motor? I betcha one of those would fit in the hilt. Maybe that's TOO powerful, I dunno.

 

[Lichtbringer]

My first try would be a slow speed Bühler - what is top for a rc tug or big(er) ships (a lot torque for the motor size), can´t be bad to keep the rod moving

Thanks for al your help guys . This is something I've always wanted to add to my ANH saber and y'all are awesome.

Just for informations sake - this stunt and the Obi Wan stunts were converted for ESB and ROTJ. Round metal blades replaced the wood ones and large allen bolts were used as set screws.

What about an xbox 360 controller rumble motor?

Seems like that would be pretty darn weak.

I'm not exactly sure how much power it would take but I know that 360 motor is cheap and small enough. And with enough power it's pretty strong. Not necessarily the solution, but it is something to consider. https://youtu.be/KYDWNO4xQac

PropReplicator2 , just in case you've missed it, I'm now trying to sort this out on my thread :

To answer your original Q on motor - Jon Bunker (friend of Vadermania), who worked on making these, has told us it was a Marklin motor (prob from a model railway loco) 6V with 20:1 (?) gear box.
