No, the trim pots that are located on the side of the tree will NOT help your problem. Those trim pots are for the setting of when the take up rollers will activate the take up motor or the brake. (This is what I was told) I have checked the LED at the end of the platter arm, I did find that some of them were dirty with metal shavings from the brain stem, I cleaned it and it seemed to help. What I had to do, was buy 17 T-Handled allen wrenches so each platter has a wrench to adjust the brains during show. Most of the time, we just leave the wrenches in the brain during the show to adjust them at the first sign of trouble. I hope that our tech guys can get this fixed. I gave them 12 brains to be sent back to Big Sky for replacement. I think the problem is that light/dark sensor tape on the base of the brain stem. It seems to get dug up during the change. I asked Big Sky to send me just those tapes so I can replace them, but I am still waiting for them. If you can find a solution let me know, and I will do the same.

If you dont have the manual, I will get mine scanned and send it along to Brad so he can add it to the manual list.

On the subject of microswitch platters, I think it's really funny how on that other thread where everyone was saying how brilliant Strong microswitch platters are, I jumped in and mentioned how similar the ORC "Super Platter" was. Then all of a sudden everybody got really really quiet! Christies sound much simpler to deal with than these Big Sky platters.

Judging from the two installations I've seen in town, I think Big Sky's quality control has fallen off a lot lately. The Brenden Palms 14 has had very little trouble with their platters (the MUTs were another story), whereas poor Crown Neonopolis 14 had almost nothing but trouble with theirs, at least initially. The two installations were only about six months apart. The guys at Crown ended up having to do a lot of "field engineering" to get their platters running smoothly--work that should have been done at the factory prior to shipment IMNSHO.

Ogenki de,

We have a Big Sky platter. It is wonderfully reliable. One of the major points about it is the fact that IT DOES NOT REQUIRE TIMING!
The pay out is powered without regard to the takeup and therefore need not be "timed" at all.

The simple adjustment of the brain is for the point at which the sensing arm causes the platter to begin rotation. From that point on, the arm causes the speed to increase, decrease or even BRAKE if necessary.

Please go to the Big Sky page and see a demonstration of how a potential brain wrap 'repairs itself' in less than a minute. This simulates what could happen when you forget to take the adhesive off the second wrap from the beginning of a reel and it draws the film in toward the brain.

The platter system 'knows what you have threaded it to do' and the payout does not operate until the projector calls for film.

If you have trouble with any manufacturer's equipment, the best way to get the straight story is to call the builder. They have everything to lose when people start to talk without information.

Soap Box returned under the lamphouse!
