That's exactly what I did as well! I used a v. small bulb from a dashboard light (5w) and an old battery charger, left the stuff in the tank for a few days and have had a lot of success with the method. Another benefit is that it seems to unsieze rusted nuts and bolts, I had some mud flap brackets with M5 studs on them which just snapped off when I tried to remove the nuts. After a bit of electrolysis they undid without problems. There's a good explanation of how it works http://myweb.tiscali.co.uk/andyspatch/rust.htm

Thanks to everyone for those fascinating and informative replies, I am hugely impressed with the breadth of knowledge available from HMVF members and their willingness to share it. Thanks everyone.

I found this picture in one of my father's books of photographs from the Cork Examiner newspaper. The caption reads: "Armoured Railcars in Cork - In 1922-23 when the Anti Treaty forces inflicted much damage to Irelands Railways, the new Free State Army formed a special Railway Repair and Defence Corps. Here are some of its members with two of their armored railcars at Cork station" There were obviously at least two different types and they look to me like lorries of the period fitted with armour and railway wheels, are they Crossleys as used by the British in Ireland and perhaps left behind or captured? Anybody know anything more about them?

Just got back from watching the London to Brighton start at Crystal Palace, the Dennis looked and sounded magnificent. Good luck chaps!

The Heavy Equipment forum thread is a great find, there is a link to a Youtube Channel called skadill with videos of "Finning tank drills" operating. I'm completley new to this but there look to be a few Sherman bits (bogies?) in this one? http://www.youtube.com/user/skadill#p/u/26/og8sZBi_GbQ With a cold start and close up of the undercarriage here http://www.youtube.com/user/skadill#p/u/13/hqJAJEgBbFo
