> - whether I can just apply some WD-40 and hope it finds its way to the critical parts
Please do not use WD-40 it is not a lubricant. The "WD" stands for "Water Displacement" and that's what it's for. Over time WD-40 turns into a thick sludge. Try using a penetrating oil like "Liquid Wrench" and let it soak - or some graphite based lock lubricant. Eventually you should disassemble it and clean it with naphtha (lighter fluid).

I have wanted one of these for a while so thanks to Peter for posting about it. The instrument seems to be in pretty good condition but the LHA mechanism is stiff to turn and I am wondering about attempting to free it. Before I blunder in, I should be grateful for any advice on: - what lies inside the LHA mechanism - whether I can just apply some WD-40 and hope it finds its way to the critical parts - whether I could disassemble it with any hope of putting it back together Best Wishes, Geoff -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Peter Mayer Sent: 23 June 2009 10:33 To: Sundials Subject: Sundial compass on eBay Hi, There's an interesting-looking RAF sun compass for sale on EBay: Collectables > Militaria > World War II (1939-1945) > RAF best wishes, Peter -------------------------- Peter Mayer Politics Department The University of Adelaide, AUSTRALIA 5005 Ph : +61 8 8303 5606 Fax : +61 8 8303 3443 e-mail: [email protected] CRICOS Provider Number 00123M ----------------------------------------------------------- This email message is intended only for the addressee(s) and contains information that may be confidential and/or copyright.
