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.
I had an accident last night while preparing a trilobite from a new location. I had just finished air abraiding the trilobite and was getting ready to start using my landscaping scribe. Just after I started smoothing out the matrix apparently a drop of oil sprayed out of the tool onto the trilobite and matrix. I tried soaking it in water with dish detergent since the soap has a mild de-greaser in it but it didn't help. Any suggestions on how to salvage this piece would be greatly appreciated as it's only the second complete trilobite from this area in seven years and it's nicely inflated. I know why oil came out the tip of the tool (that issue is fixed) so I really just need some advice on how to clean it or suggestions to improve its appearance. Thanks, Andy
Sometimes a fossil shows more of its detail when wet than when dry. The photos below show what I mean. What is a good way to treat the fossil (I mean with oil etc.) so that it will keep the more attractive wet look? The first photo is dry, the second is wet. The pictures were taken with the same lighting and camera settings. Russ
