Restoration work for a Museum - a mechanic's perspective
Hello All,
After having some down-time today I went for an online look at some of the goodies available at the Australian War Memorial. I came across an article by a mechanic that explains how he had to change his approach from being a tradesman – mechanic into one of being a conservator. It is a pretty good read and I hope other people can enjoy it too. It mentions things like deciding what to do with "historic dirt". http://www.awm.gov.au/events/confere.../tradesman.pdf Kind Regards Lionel

Corrosion: Restarting a motor after it sat for two years
Hello All,
Following on from my online trek at the AWM I found this article about restarting a motor after it sat for two years... There are some good pictures of the pistons. The article Corrosion, wear and corrosive wear; the story of lubrication systems in large technology object storage and use is written by David Hallam, David Thurrowgood and Col Ogilvie of the National Museum of Australia Figures 5 and 6 (shown on page 6 - no pages numbers in article) show our Land Rover. It’s done 3,802 miles since 1958. A thousand of those miles have been done in the museum service. It’s been filled with a standard lubricating oil. The lubricating oil has been changed about every year. Last time it was used, it was used for the royal tour. We were starting a maintenance program on it and we thought “Well, we’ll whack an introscope down and see what’s happened inside it”. It had sat for about two years.You can see there the corrosion. If we had kicked that engine over, what would have happened? The piston would have gone up and scraped the corrosion off. What’s corrosion? An oxide. What are oxides used as? Abrasives. What size are they? Very small - small enough to go through the filter. So what you’ll end up with is this very fine abrasive slurry, that won’t be picked up by the filter, rotating round and round inside the system. And that’s exactly what happened with my Volvo. I ended up with this nice abrasive slurry and it went through and it ripped out all of the oil seals and did a whole lot of damage. In the museum, if we had kick started the Land Rover, the same thing would have happened. Okay, how have we vercome that? We use nothing but inhibited oils, we don’t use any standard lubricating oils in our institution. The article has colour images and is found at: Australian War Memorial Accessed 9th August from, http://www.awm.gov.au/events/confere.../corrosion.pdf Kind Regards Lionel

Very intersting reading Lionel, I'm sure most of us here have engines that have not run for years and that article certainly makes a lot of sense. I for one will take heed.
Colin.

Hi Lionel - very interesting articles. However I have one question, what is "Downtime?" I don't seem to have any of that. Do you know where one can obtain it?

Downtime is when we, sit - sip coffee - talk sh*t and when we do field trip raids for "Stuff".  Cheers Tony
