scrapbuilt theatre projector-new episode idea : LUSENET : Junkyard Wars : One Thread

Here's a new idea:building a scrap built 35 millimeter theatre projector. A small single cylinder aircooled engine or an electric motor woud power it. 35 millimeter projectors mostly use a rotating intermittent sprocket to advance the film in proper frame. Maybe one with a pulldown claw would do. The intermittent sprocket is mostly operated by a mechanical Geneva Maltese cross movement-a four slotted starwheel- but newer projectors such as those made by Kinoton use a four position DC stepper motor to drive only that sprocket. All theatrical film projectors use a rotating shutter besides upper & lower feed sprockets plus a film gate assembly. For help and advice,visit or Strong mostly makes Simplex&Century projectors while Film-Tech has a forum for discussion.

I think you should have a episode where they have to make a mini plulse jet engain. that would be cool or they could episode where they have to make a helocopter that really flys with a engian on it!!! thanks Keep on makeing good episodes!!!!!

A helicopter would be a sure way to kill someone.

Don't plan on ever seeing such a challenge.

The point of the show is to build machines, not terminate the contestants.

I'd like it, and if it would surley kill someone might as well be George. I think a good project would be to make a crusher machine to crush George (just kidding)
