Replacing the tip on a Badger 150 airbrush

I've suspected for a while now that the tip, the tiny nozzle on the business end of my airbrush, was damaged. I could still get good results from it, but I noticed that the needle protruded further out than it used to, and the spray pattern was slightly off when cleaning the 'brush out by running screenwash through it. Here's the head and tip assembly;

For this job I needed a new tip, some beeswax, a special Badger three sided reamer (part number 50-061) and, a lighter;

The tip is a mere 4.3mm long.

To remove the old tip the reamer is inserted into the head, and used to unscrew the tip;

The new tip is placed gently on the reamer and has a little beeswax smeared on the thread;

Then it can be screwed into the head until its fully seated;

To seal the thread the tip is held over a flame until the beeswax has melted, this takes seconds. Then the excess can be wiped off and the 'brush re-assembled;

A five minute job, which will hopefully improve my painting.

The above also applies to the Badger 100 and 200 airbrushes (but not the 200NH), which share the same head and tip with the 150.
