  1. Thank you Dom, The unusual looking set of hex bits almost seem out of place in this kit. Aloha
  2. This tool kit is for sale on eBay. https://www.ebay.com/itm/Service-Tool-Case-Kit-Arriflex-Reparatur-Repair-/323691656503?_trksid=p2047675.m43663.l10137&nordt=true&rt=nc&orig_cvip=true Can anyone identify which camera model it is for?. Or perhaps it is general purpose? Aloha, Mark
  3. Thank you very much Dom for your work on this! Who knows, perhaps this will lead to increased work for the few professional technicians still servicing these cameras. I'm only half joking. Mark
  4. Hi Dom, (or others with the knowledge) Would you ever consider making a service and repair guide for the Arri 16S similar to your Arri 35 Cinetinker blog? I really hope someone with knowledge, skill and love of this camera will do this at some point. I fear the knowledge will die long before the cameras are ready to give up. I understand the special tools and gauges aspect is an issue, and not knowing the specific requirements, I have no idea of how practical it would be to make the required tools that can no longer be found or to develop replacement jigs and gauges. My own experience in engineering and optomechanics would lead me to think this would be possible if more detail about the specific issues were available. One simple example is the take-up reel tension adjustment. This is easily adjusted using the Arri tool made specifically for the task. However, the adjustment could also be made if one knows the required tension value gauged by the Arri tool. What is that value? Can anyone actually answer that? I would bet most experienced technicians know this tension setting by feel alone. Flange focal distance is another example. Simple tools can an be used to gauge this distance. These tools are not cheap but neither are they prohibitively expensive. Tension measurements can be easily tested but the specifications must be known. Certainly, skilled service is still available but service cost limits the practicality to professional users. The skilled hobbyist has zero chance to perform detailed service given the current state of available documentation. Please tell me if I am way off the mark but I think there are many skilled hobbyists out there dying for guidance that would give them a fighting chance. I know I am. Aloha (Sorry for this double post but the other was in a long dead thread so hopefully this will be more likely viewed here)
