Surveyor Posted October 20, 2017 Share Posted October 20, 2017 Has any one any experience of trying to get the bubble that forms in the liquid out of one of these? Also what is the liquid? Quote Link to comment Share on other sites More sharing options...
Tony B Posted October 20, 2017 Share Posted October 20, 2017 The liquid is normally alcahol. There are a number of you tube vidios and various web sites on re filling compasses. The liqiud is avaialable, you may even find a refilling service. Do a search the amount of results will suprise you. Quote Link to comment Share on other sites More sharing options...
ferretfixer Posted October 21, 2017 Share Posted October 21, 2017 Isopropyl Alcohol is used in these. Usually using a syringe with a needle. Injecting the fluid will push the bubble out. But then you have to seal it again afterwards! IRRC it is plaster of Paris used to seal them?.. Quote Link to comment Share on other sites More sharing options...
