As with all legacy drawings my first job is to part them out into individual part jpegs, clean up the drawing of each part and lay them out on A4 sheets. They can then be printed out and ISO Metric measurements added - I normally do these in red pen. The drawings are then rescanned and individual pages can be printed off to take out into the workshop as required

This is a good tip Jo. Simple but sound. I have a set of castings in imperial (still on my shelf, still scared to touch them) but my shop is geared up for metric and I have been a bit worried about the hassle of converting the units as I work. It makes a lot of sense to convert all the dimensions and mark them in red on the drawings
before starting the build as you suggest.
