Hi I bought a 2nd hand air scribe some time ago. It seems to be a CP9361 with a modified front piece (I assume PaleoTools). The tool seems to work very well (muuuuuuch better than electric engravers). The seller did not give me any info about maintenance though. I assume that the tool requires some oil? If so, what type of oil should be used? Does normal WD-40 work or do I need a special oil for air tools? Also, where do it put the oil exactly and what amounts? Sorry if these are stupid questions, but I am a little bit afraid that the wrong oil will damage the seals or the oil will be sprayed onto my fossil by the front nozzle.
Since I started buying fossils online in 2013, my collection has slowly but surely shifted from being a generalistic fossil collection to mainly a dinosaur and reptile fossil collection. With my collection increasing, some things have come to my mind about where to go next with displaying and maintaining my collection, along with guidelines as to what standards I should have when purchasing fossils. I will list them below, and would like to hear your feedback. 1. I currently display the bulk of my collection in an open cabinet that collects dust. It seemed like a good idea at first but the dust it's slowly gathering is obviously an issue. I've seen members display their teeth in IKEA cabinets, which look much better and might not collect as much dust, but living in a country prone to earthquakes I must question whether this is a safe method of display. I don't want to buy an expensive cabinet that looks good only for an earthquake to hit and destroy it with the fossils inside. What would tooth collectors overseas do about this? 2. The most important information about a specimen is the location. Recently, I have strived to know as much as possible about where the fossils I purchased have been found (more on that later), and obviously this should be labelled. I wonder if a commercial label printer would be any good for this, as I don't have a working computer printer and printed digital text looks much better than my handwriting. Has anybody had experience with using label printers for their collections? 3. More recently, I have developed tighter standards for buying fossils than I've had before, even for last year. I will now only buy fossils either from the original finder or otherwise with precise locality information (not just the formation and state/country). When possible, I like to know the name of the quarry where it was found (if applicable), when it was found, and who found it. All of these are provided with a T. rex tooth tip I bought directly from the finder in South Dakota, as an example. Sometimes I will settle for a county and formation if the provenance is otherwise solid (Texas dinosaur material, for example). To be more of an ethical collector, I will also now avoid fossils from countries with bans on fossil trade and export, such as Niger and especially Mongolia. This means I can no longer tick dinosaurs like Suchomimus and Tarbosaurus off my bucket list, but I can always buy similar remains legally. 4. Adding to the above, I would like to get rid of some purchases I made in the past that seem to me now like poor choices, cluttering up an otherwise good collection. Some of these I will sell (not via the forum as I only accept local pickups) but have had no success to so far, others will be given away as they don't have much value. Does anyone have any suggestions as how I could get rid of these "cluttering" pieces? Just wanted to get all this off my chest. Thanks in advance to those who answer the questions I have.
