Boat Forum / Building / May 2006Plastimo Contest compass liquid
My elderly Plastimo compass has deleloped a bubble inside the globe. Does anyone know what type of liquid Plastimo uses to damp the card? Many thanks in advance Matt I don't know about Plastimo but I believe a lot of compasses (compii?) use distilled kerosene. The trick is getting it in. I spoke with a shop once that did it and they adviced getting a new compass. > My elderly Plastimo compass has deleloped a bubble inside the globe. > Does anyone know what type of liquid Plastimo uses to damp the card? I'm not sure about Plastimo, but Silva uses mineral spirits. I believe that most compasses are filled with mineral OIL, not spirits. Of course, I'd check the your specific manufacturer to be sure.

Mine was definitely mineral SPIRITS, as the smell is unmistakable. Mineral oil would be much too thick for a small compass, anyway and might not work at all in cold weather. > Sincerely, > Jason [quoted text clipped - 3 lines] >> >> I'm not sure about Plastimo, but Silva uses mineral spirits. Don't know about Plastmo, but for aircraft compasses, check http://www.aircraftspruce.com/catalog/inpages/repairkit1.php $1.71 for 1/2 pint which has to be the least expensive thing they've ever sold. (before shipping) Roger (forty or fifty years ago it was ethyl alcohol -- the good stuff) derbyrm@NOSPAMinsightbbNOSPAM.com http://home.insightbb.com/~derbyrm >> I believe that most compasses are filled with mineral OIL, not spirits. >> Of course, I'd check the your specific manufacturer to be sure.

I like your input of ethyl alcohol filler, in case of emergency it goes well with Coke. > Don't know about Plastmo, but for aircraft compasses, check > http://www.aircraftspruce.com/catalog/inpages/repairkit1.php [quoted text clipped - 20 lines] > >>> > >>> I'm not sure about Plastimo, but Silva uses mineral spirits. Here I found these two interesting articles: http://www.andrewscompass.com/checkoff.html http://www.newton.dep.anl.gov/askasci/gen01/gen01791.htm |
