Painting wheels

When I built my NS 7005 I found it pretty hard to paint the wheels. This photo shows how I masked the treads, in this case of the wheels from the BR 98.

A very tedious job indeed so I decided it should be done in a less time consuming way. Well the answer is simple: I bought a template with circles for drawing purposes. Put the wheel in, sparay, doen. No masking no fuzz, thirty minutes of laborious masking saved, per axle that is!!!!
