Hi folks,
I have lurked here for months and learned a lot. But now I have a problem and I could really use your help. I own an Eprad Jumbo Sword, model 51000. I am having trouble figuring out how to take down prints with the make-up table on the Sword. I have no problem making up prints on the table. My problem is I can get only clockwise action with the large right reel on the Sword itself. I can control the direction of the spindle on the make-up table, but the large reel on the Sword won't cooperate. I have read the sword manual at film-tech and the method to use when taking down prints with the make-up table isn't specified. I have another Sword manual and it doesn't discuss this either. It does mention that you can take down prints with the make-up table, so obviously it's possible. If someone knows how to take down prints from one of the large reels to a reel on the make-up table, I would surely appreciate the information.

Hi Gordon,
Here's my problem:

The only way to activate the make-up table, is to have either the left or right large reels running. Then I can turn the make-up table on and have it spin clockwise or counter-clockwise. But, to get the large reels spinning in the correct direction, I need to raise that reel's dancer arm beyond parallel to the floor. If I leave the dancer arm unused, the large reel simply won't spin. Normally the make-up motor and reel are in sync and spin up and down in tandem, avoiding spilling film all over the floor. Not so with the dancer arms elevated above parallel. I have tried so many ways to get this to work. I hope someone can tell me what to do.

How do you use the dancers when you rewind are both used.
In the worst case feed from the reel that is unrewound through the rewind dance and up to the make up spindle
We had two swords that we modified for 35/70mm and we completley rewired the unit

"How do you use the dancers when you rewind are both used."

Well, when rewinding onto a large reel on the Sword's main axle, the dancer arm on the reel paying out the film isn't used. The reel taking up the film, is. I hope my answer makes sense.

"In the worst case feed from the reel that is unrewound through the rewind dance and up to the make up spindle"

I'm not sure I'm following you. I can't get the make-up spindle to start unless I run film through the dancer arm. Problem is, it spins the reels in the opposite direction from what I want. I can't get the large reels to move in the proper direction. I can control the direction of a reel on the make-up spindle - no problem, as long as the motor is activated. My problem is getting the large reels to pay out film to the spindle. They just don't want to do it. I must be doing something wrong.

There is a "cheat" that I can use to rewind onto the make-up spindle. I raise the right dancer arm slightly. There is no reel on that axle. The large right spindle runs reel-less, in the wrong direction, but the make-up motor is activated and I can rewind onto a reel on the make-up table with a large reel on the left side of the Sword. No dancer arm is used on the left side. This is a very clunky method and unless I rewind very slow, it puts stress on the make-up motor. I hope someone can clear this up. My "cheat" method is pretty clunky.

Thanks for your help!

My Sword has no position 8. I have only 2 thread modes, run (large reel), rewind (large reel), make-up right and make-up left. That's it. I am using the Eprad Jumbo Sword, model 51000.

The schematic is in the manuals section and it shows in the photo only what you describe but the schematic shows more unmarked positions it is drawing C-40733-2

Gordon,
I'm going to have a professional film projectionist come over and troubleshoot my Sword. I don't know how to interpret the schematic you refer to. I see it, but I don't know what to make of it. Maybe my friend can help. It looks like I'm back to my rewind "cheat", for now at least. If anyone else has any ideas, I'd like to hear them.

Thanks, Sean. I'm in NYC. The neat thing about the Sword is that I can watch an entire movie (or even 2 or 3 movies) on one reel. My Jumbo Sword can handle up to 4 1/2 hours of film on a 48" reel. My overall impression of the Sword is very positive.

"He who lives by the sword..."

Sorry, I had to.
