Generally, for feed and takeup reels ("spools"), a larger hub reduces the tension variation on the film. The normal 50mm and 75mm cores are likely too small to give good results. A 100mm or 125mm diameter would be preferred.Frankly, it may be more cost-effective to find a source of cast metal "house reels", or at the very least, some of the older design high quality (one piece, not split-apart) plastic shipping reels. ------------------ John P.

When old theatres convert to platters, or close, the welded iron or cast duraluminum "Goldberg type" 2,000 house reels are often stashed in attic, basement or behind the screen storage areas, gathering dust. A visit to the foreman of a demolition crew, or owner or manager of a renovated theatre, sometimes enables one to strike it rich. On Long Island's North Shore, I have seen estate tag sales where the contents of private screening rooms contained such reels, often in the old "Neumade type" film storage cabinets. I had no idea these reels would some day be hard to find in some locations. Have you checked theatre supply warehouses for used house reels? [When a house reel had a slightly bent flange, projectionists used to dab the hub with paint, indicating "Run with this side out" so it wouldn't scrape the film magazine.] We would not run film on sheet metal shipping reels, except perhaps during the last show, when the film was shipping out, but only if all shipping reels were in good shape.

You got to be kidding! I deal in these reels all of the time (and those Neutype reel cabinets too). Unfortunately for you, I am not located in Brazil. What size spindles do you use? 5/16" or 9mm? In the US, 5/16" is standard (for 2000') in metric speaking countries, the 9mm spindle for the 600m reel is common. You can see most of the items discussed...2000' cast reel, Neutype 12-reel storage cabinet and a 2000' 35mm split reel (apart). This is from my most recent installation...the Goethe Institut (pronounced Gir-Ta Institute) in Washington DC. The other pictures will hopefully make it to the picture gallery someday soon. I suppose, if you are interested, we can see about shipping...if you desire, contact me via e-mail. Steve ------------------ "Old projectionists never die, they just changeover!"

Ok, the next picture has what is commonly called a "sheet metal reel." It is a 6000' reel but they come in just about any size imaginable. They also come with fixed flanges (solid hub) and floating hub (the ones shown)...BTW this photo is of the current state of the Williamsburg Theatre's (now called the Kimball Theatre) main projection booth. There are pictures here in the gallery of how it used to look. This booth uses 1/2" spindles (it was that way long before I became involved with the project) which are preferred for running large (6000'+) reels. BTW 9mm spindles use a drive dog pin rather than the "key" that is associated with the 5/16" spindle. Steve ------------------ "Old projectionists never die, they just changeover!"
