Hello out there

It just struck me that one should be able to construct a longplay unit this way: take a "parts"-16mm projector that you´re willing to trash, and take transformer, motor and both arms from this. Then construct a box in wich you mount this so that the arms will operate properly, with sufficient room for large reels -the way the Eiki longplay unit is set up. Lastly tweak the take-up and give resistances to work with large reels.

Would this work? What are the pitfalls? [Roll Eyes]

Cheers
Lars

Take a look at the Eiki Long Play tower. It was actually designed and originally built by Elf in the UK (they did a lot of incredible modifications to Eiki projectors including a dual band machine).

The Eiki tower uses one of the take-up torque motors from the 6000/6100 series Xenon projectors, but the design is really easy. Two reel shafts, a motor which you can adjust to take-up (an arm could sense torque and be connected to a variable resistor to change drive torque) and just high enough to clear the large reels.

Then all you need is a couple of idler rollers to go over the projector shafts for feed and take-up reels to guide the film.

Are these units hard to find?
Are they expensive?

They show up in the US from time to time for about $500-600. They were mainly sold with the EX-4000 so it would have the same running time as the EX-6000/6100. Of course US models are 110 volt machines.

I have one, and I can vouch for its quality; it works very well and is quite gentle on film.
