The completed Ross

The Ross has turned out well, it had heavy pitting and took a lot of work. As you can see it does not look brand new, it still has signs of its age. The Ross was polished entirely by hand before lacquering. It needed several new screws at the rear and on the bar of the microscope as the original metal used contained a lot of lead which shears easily.

This is a complex microscope, every single screw was hand made to fit each screw hole. The left hand screw of a pair is not interchangeable with the right hand screw so it was important to write down and photograph where each and every screw came from as the microscope was taken apart. I’m a big fan of standardisation but that came later.

Not all of the screws were put in straight either! The legs which should be interchangeable, being identical shapes, were not interchangeable as whoever made the microscope screwed one of the screws in at an angle of about 20 degrees. Nobody could ever argue this was  anything but completely handmade. A handmade microscope deserves hand polishing and hand lacquering. I have a new respect for (and a few new grudges against) Mr Ross.

The only parts I have not relacquered is the Wenham Prism. The heat involved in hot lacquering could easily damage the prism so it’s best left as it is. The mirror being very chunky acts as a great heat sink so I was able to relacquer that.
