Since years I use a Bosch multi function power tool PMF 250 CES. Recently the fixture for the vibration tool broke. Neither the spare part nor a new Bosch machine with the same kind of fixture are available.
This renders a whole (expensive) collection of tools useless.

The German post describes a repair – or modification to be precise – solving the problem.
Sorry for having no English version; my tool time English is too poor.
Even when understanding quite few of the German text the pictures might, hopefully, be self explaining.
