I have a question is their any one projection company that manufactures everyone single part of its components (excluding hardware: screws, nuts, bolts rivets. What I mean by this do they manufacture the castings, machine them, bend the sheet metal, turn down all shafts sprockets and gears; make their own dies and tooling? I doubt there is.... I just want to know if there is any company out there that controls every aspect of their operations under their own roof, or several buildings in the same country?
Mark I have my hands on a 1940's southbend gear head lathe, however I have no way of getting it home. If is on an outside loading dock and has been rusting away for over 10 years now. I could have dismantled it while at work, but I really did not have the time back then when It was given to me. i think later in the year the school is tossing it in the dump. the atlas is a nice lathe got it off ebay a while back, but i really do like the smithy. scored it form a guy in PA for 150.00 I just needed to haul it out of his house.

Steve... Don't let the disappearance of the chokes stop you form selling them... you can always add the chokes back in for your customers if you want! Custom wound chokes ARE NOT EXPENSIVE.
You miss the point...I was on topic of this thread in that a manufacturer chose to cut costs in a manner that can demonstratably lower quality. I was not questioning whether one could add that or any other "improvement" to an off-the-shelf product.
quote: Mark Gulbrandsen
Its long been known that painting heatsinks with black paint actually keeps the heat sink from radiating efficiently. The only "Black" treatment that actually works to increase efficiency is black anodize.
And I'm sure you can site the studies and examples to back that statement up since it has "long been known." In truth, I was neither endorsing or rolling my eyes at it...just stating what its most likely purpose was.
quote: Andres Briano
If Black Body Radiation was the cause, why had they left a strip unpainted (where the diodes screw into the heat sink)?
Well since the heat sink also forms the plate for the positive or negative output...it still needs to be electrically conductive where the diodes attach. As a manufacturing process, one could try and mask off the specific areas where the diodes will mount (and ensure the mask area is larger than the largest washer that might be used)...or just make a single mask that insures that the diodes will make contact.

Here´s another "no-issue" for you all.
Have you seen the latest version of the Platter Select buttons (?) Errr... switches?
I'm with the others on this. The AW-3 switches were a case of elegance getting in the way of reliability and servicability. Note, Christie actually tried to keep the push buttons once after the orignal ones became obsolete (went from the squarish to rectangular)...they finally went with something less custom that seems to have offered no down-side. I do, however, discourage the use of RS switches...unless you are trying to get a show up and going. With standard 1/2" toggle switches...one can set their own quality level too as there are several manufacturers and with different grades available.
quote:
Agree with them or not Tim and Andres Christie Quality has beaten the pants off everyone else in the industry including Kinoton!
Clearly a bait for me...the resident Kinoton cheering section. Christie has continually improved their equipment...then again, they have continually needed to just to catch up with others on many things. Christie's stuff is pretty uniform and about as consistantly assembled in the factory as anybody...including Kinoton. However as to final result...oh please...they are no Kinoton. I don't see the studios around the world pulling their Kinoton's for their Christies...in fact those sales seem to be holding their own these bad old digital times. In fact, we still seem to be installing Kinotons into non-studio rooms too.
Mind you, I'm not trying to take away anything from the people at Christie...they are quite fine folks and have been most helpful and supportive over the years...though they aways seem to be the first to obsolete things...as compared to others. While were on the subject...I know Strong seems to be the whipping post of some...they do have the majority of installed machines in both US and Worldwide...it is easier to pick on them and they DO have their golden people. I defy anyone to think they can find a better customer service person than Paul Sanchez at Strong. Everyone at Strong has treated us pretty darn well over the years.
quote: Tristan Lane
Does Kinoton make their own sprockets, shafts, intermittents, and such? I know that much of the electronics used in the projectors are obviously made by other companies, but is it OEM stuff or off-the shelf. Can you order a direct replacement for the Lenze inverter from a source other than Kinoton? Could you even order a different brand of motor controller?
I don't think you will find that any projector manufacturer makes EVERYTHING in-house. In the case of the Lenze inverters (there are several used...depending on the product) are often off-the-shelf items but with Kinoton programming. Again, depending on the model of equipment determines what alternative products you could sub. It is all in how the machine is controlling the inverter and what the machine expects to be happening. There are also quality factors as all inverters are not created equal. One thing is for sure...if you sub an alternate part, don't expect the manufacturer to back up the warranty on any subsequential damage. One thing a manufacturer does when they use a particular product (and any value adds they do to it) is to also ensure that it will properly work in the application that is intended. The manufactuer also has to contend with obsolesence...if the product they are using is discontinued, and they have to change devices, they will need to have either enough deep stock of the now obsolete product to ensure service life, or provide a means of an upgrade path to a current part.
If you look at a Kinoton projector (the mechanical parts)...it is really the art of simplicity and thus you will find that most, if not all of those parts are made in-house or by direct contract. There are really very few (mechanical)parts inside.
