The 'Tools' refered to were special tools produced by Bell & Howell (that name was always Spoonerised..) for the alignment of said projectors. The manual for my 655Q shows them, but not in sufficient detail (or with dimensions) to make them which is a pity.

I think _with_ the tools it's fairly clear how to do the alignment. Without them it's going to be a lot harder. Possibly you have to work out what you are adjusting and what the correct setting should be (minimal clearance -- but some -- at some part of the cycle ; or equal clearances between parts, or...) and then hope you can do it.
