Technical Drawings?

[Artefex]

Does anyone know if there are schematics available from anywhere?
It would be useful to have a drawing that includes all the important dimensions like tube diameters, gear dimensions and distance between bearings etc..
I was considering drawing at least the gearbox in Autocad if theyre not already available.

Perhaps the esteemed immortal gaurdians of this forum have come across drawings over the years?
