How is a pistol grip made? Video with Thomas Rink

I noticed this video on the Rink website.

Machine translation: How is a custom handle created for a pistol or air pistol? At a world-famous Griffbauer I have a Maßgriff build. I show you the individual work steps from desire to the finished product. Thomas Rink willingly provides information on how to build a pistol grip. In addition, I show you an insight into the workshop in which the handles arise.

Great vid, I wish I lived close enough to get a custom fit.

Very informative. I've got several Rink grips - they are superb. 

Having watched this video, I wonder if there is a way to do a "remote" custom fitting. Need to think more about that.
