I beg to differ guys...
Without for a moment questioning your finding the Neumade joiner to be superior, I would nevertheless like to make a few points in defence of the CIR design;
1. The model Joe Redifer reviewed is the SPECIAL, which is only intended for use in film archives, speciality houses, etc. Gordon has already pointed out the purpose of the adjustable pins on the left-hand end. On the right-hand end, the retractable pins also help with deformed film, and are also used to permit a greater overlap cut in particular situations. For example, we've all seen "jacknifed" head and tail splices, where one of the frames is considerably shorter than the other. The retractable pins allow one to slide this frame sideways, whilst still held accurately in the channel, and cut it back precisely so that the next frame comes back into perfect registration.
Anyone using this splicer model in a multiplex should check the pin alignment by laying a fresh piece of film in the channel (say a trailer head) and making sure the film lies completely flat, with no strain on the perfs where they sit on the pins. If not, the adjustable pins should be moved precisely. THEN the adjustment knob should be LOCKED by tightening a setscrew located above the knob casting, using a jeweller's screwdriver. This is countersunk into the lip of the film channel and is visible in the review photo.
This is MOST IMPORTANT as ANY discrepancy in the pin alignment will change the perf pitch and cause those jumps in the gate. In any case, multis should only have to use the STANDARD model, which has none of these refinements and has fixed pins.
2. The CIR splicer MUST be regularly maintained and checked for alignment to give its proper performance. But what's new about that? It's the same for any piece of equipment. I would say that almost ALL the problems quoted here are due to tiny misalignments, and especially adhesive build up. Even if you strip it down and thoroughly clean it, it MUST be very carefully reassembled and adjusted, paying VERY close attention to the blade position and the alignment of the punch, as well as the picture guillotine (it is not a blade).
In my experience blades are blunted and the punch damaged very quickly when misaligned. It makes sense, because even a slight error will cause the blade to unduly strike the steel platen on the film channel, and likewise the tips of the punch to hit the edges of the holes in the platen. Also, the sprung handle must travel smoothly and freely up and down on the steel pillars, if not, undue force will be exerted on the punch and tape cutting blade. (Usually I slightly grease these).
Note that once the adjustments are made, they don't have to be altered every time you clean the splicer. In other words, it can be dissassembled enough to clean without further disassembly that would affect the blade and punch alignments.
I would agree that it takes a bit of trial and error to get it to work perfectly, and time isn't something in great supply in cinemas today, BUT once it's lined up correctly I can vouch for excellent performance, with NO undue jumping in the gate, ZERO perf damage, NO tape "squares" stuck to the film, etc. etc. Believe me! I recently refurbished one of these splicers, that was held to be "beyond repair" and spent a lot of time on it, and it's as good as new.
Maybe you'll upgrade your review Joe from "Blows" to merely "Sucks"?
