We could probably do it, yeah - we could also probably use the Physics Workshop facilities to work on the mount and stuff.<div><br></div><div>Before we do any dismantling I'd like to clear it with Professor McArthur though, so let's draw up a proper plan for why we want to take it apart, what we're going to do with it when it's dismantled, any special equipment we'll need to not break OH&S etc. </div>

Is there a chance we can dismantle the thing and spirit bits down the stairs<br>
and off to UCC (Stories of the justifying the original cost of crane<br>
notwithstanding) ?<br>
