The shutter on my #2 Strong/Simplex 1060 projector is loose. I was getting shutter ghost during the credits. There wasn't any more room on the adjustment on the top of the machine.I stopped the show, took off the side panel and could see that the shutter was out of time. So I grabbed my Allen wrenches and tried to loosen the shutter so I could turn it. I discover that I could move the shutter on the shaft without loosening the Allen screws. So I retimed it and tried to tighten the screws. I had difficulty figuring out which Allen wrench to use. It seemed to be in-between sizes. So I just closed the side cover and got on with the show. Next stop is the hardware store to buy the best, most expensive set of Allen wrenches I can find, with the balls on the end so I can do it an angle. Other than that, does anybody have any advice on how to tighten the shutter on the shaft?

You can buy a set of "T-Handle" wrenches if you like. You can get the same brand that comes in the Christie Kit if you look at "Northern Tool".You'll find they come in VERY handy for doing things like working on shutters, etc. The extra long reach makes the job a LOT easier. You can flex the tool just a bit if you need to get at a screw that's at an angle. One thing to watch out for with the ball end wrenches. The "neck", just above the ball is a weak point which increases the likelihood that the tool will break. Of course, Murphy's Law says it will break at the most inopportune time, in the most inopportune place. I learned the hard way. There's a screw in the gate of a Century that still has a broken wrench stuck in it to this day. Geez! I hope nobody ever has to adjust that gate! I'm just hoping that somebody hasn't stripped out the head of that set screw. It OUGHT to be a SAE. Most of the time when I find a loose shutter loosening it, rotating it on the shaft and tightening it again takes care of it. If the screw has lost its "bite" on the shaft this will give it something to grip.

When I did booth maintenance a few years back I used two good sets of regular allan wrenches and a full set of X-celite interchangeable "Series 99" drivers, handles and extensions (thank you Rick for steering me onto those!). These are made by Cooper Tools. I bought the ball-headed ones only to have two of the balls break in the first month, therefore I strongly recommend the allan wrenches with no balls. Guess I was a real ball-breaker. Ahem. Here's a URL to one vendor's Series 99 line of hand tools (not sure if they've been given the Barbara Feldon Seal of Approval). http://shop.store.yahoo.com/tmt/ser99intool.html ------------------ Cheers, PJ Dougherty W2IRT

Hi Ian, first, make sure the shutter is actually spinning on the shaft and it is not backlash in the gears. Then, replace the two screws, they should be 8-32 x 7/8" allen head machine screws. I would suggest running a tap through also before installing the new screws. I have seen the shutter threads get stripped or cross threaded thus they feel evry tight, yet the hub is not sufficiently clamped onto the shaft. Have fun, Post if you still have trouble, or email me. John------------------ John Eickhof President, Chief Slave Northwest Theatre Equipment Co., Inc.

Hi Ian;I'm pretty sure you've got it now. How old is that machine? I'm surprised about the cracked collar on the shutter... Glad it all worked out. Pat
