Just a tip a car mechanic mate gave me years ago 'Take out the least accessible nut/bolt first. Then if it can't be done, it saves you a lot of time and effort with the rest of the job'. Then I suppose you go for the rustiest next.

My problem now is not being able to find tools in my shitheap. I think it is an age related problem. A couple of days ago I was looking for a felt marker pen for quite a long time, until I found it in my left hand
