  1. Do you still have Arri 16 s parts?? I have a question about an arri motor control unit which came with a constant 24fps motor.  The unit had power, when I plug it into 110 voltage. It has a switch for 'forward/reverse'.  When I install the camera motor in the arri 16 s, and activate the run switch on the camera, nothing happens.  I purchase this unit on ebay and was quite aware it might not work, 

    have you any knowledge with this.  if you need pictures, I will send

  2. Yes - the red arrow should be a spring loaded port for Chronosynth I/8 - it's probably better to just disassemble the gear so the shaft can be cleaned as well. I have never seen a mag with the gears greased. I would remove each gear, clean the shafts and lightly oil.
  3. Here's the original manual: https://drive.google.com/file/d/1nOPDo63VvwE9dk9zVXQ1mvPxIYpz54mh/view?usp=sharing
  4. If the motor is truly seized, it's either the bearings or it was dropped and the inching knob and/or shaft is bent. If the barrel won't turn, it was probably dropped and damaged the housing. If the motor runs but the camera doesn't it's probably the rubber coupling which tends to deform and dry rot - I have replacement kits for those. If anyone needs any parts, I have just about everything. Sean
  5. I stumbled upon this today and thought it was pretty cool. An Arri 16S prototype. Even has a letter from Arriflex as verification. I know Tim will enjoy this: Sean
  6. I have two, new Tobin TM-23 variable speed motors for the Arri S or M for sale. I was buying these when I could because I was rebuilding some Arri S's but have no need for them now. For those of you not familiar, they are designed to run forward and reverse on 12V for 0-50fps. They can also be used at 8V for about 35fps. Be aware that if you are using mags with the Arri S, you cannot use them at 12V without modification. So, if you were to use this motor with an unmodified mag, you must use it at 8V for a max of 35fps. Price is $360, which includes shipping via USPS priority. Wi
  7. I have had pretty good success with repainting cameras here at NYU. We have a sandblaster which makes getting the old paint off pretty easy but you could probably use some type of stripper. Anyway I have been using Krylon Wrinkle Finish (#3370) which is used a lot on cars and motorcycles. It's pretty much identical to the Arri S finish. You have to spray it on really thick and it wrinkles as it dries. Heating it helps the wrinkle process but since I don't have a way to truly bake the parts, I 'baked' them under two 1K lights for most of the day and that worked well. It's not as good as the A
  8. After collecting used/broken camera parts for 4+ years I decided to do something with them. Currently only have earrings, but may start doing other stuff as well. Have some stuff made from SR2 & SR3 parts, but mainly from 35mm SLR parts. Check it: Sprocket Holes Shop Sean
  9. I still have some kits available and will make more if anyone is interested. Sean
  10. These are repair kits for the Arri S that I have developed during my 3 years as camera repair tech at New York University. We have 90+ Arri S cameras that I maintain and rebuild. Since Arri has discontinued most of the parts, I am constantly trying to figure out how to keep the cameras running. The kits are the result of lots of research, trial and error and have been proven to work in the field under the most punishing of conditions: at the hands of our beginning film students. I would not offer these for sale if I was not 100% sure that they work. When I was a student, I bought an A

  12. I should have explained better. I was just saying that there is the large cylinder attached to the normal-looking part of the motor and the inching knob came out the back of the large cylinder. Voila... a picutre.... I feel like I've seen this before I just can't remember where. Thanks Tim PS - did you get those scans I sent you OK?
  13. Don't have a picture but have seen an S motor that looks normal at the front, but is very long and has a larger diameter silver cylinder on the back with inching knob. What is this one? Have not found in my catalogs. Sean
  14. Some suggestions: chip charts (color seperation and grayscale charts) changing bag light meter - DP should have one but if you want a complete package... Filters: ND6, ND9, polarizer, 85, Clear filter for each lens to protect it. If you have extra cash: ND3, 80A, Haze, lo con, diffusion, 85ND6, 85ND9 slate tripod baby legs or hi-hat A matte box with 4x4 filters would be ideal but more expensive than screw on filters. Many matte boxes will take 3x3 or 4x4, so you could buy 3x3 to save a buck but when you rent filters it will be 4x4 since 3x3 is impossible to find. If you go that
  15. Will keep you posted. I have a few catalogs ranging form the 50's to 80's and could find no mention of it. I'm going to call Arri to see if they have any info just for the heck of it. It's a great motor, runs great.
