I will be happy to answer questions about these videos:
A bent endpin on your bass?
Video: Modifying for a bent endpin.
Here is how I modify a Gigger's model of the McNutt Bass Cradle so it can securely hold a double bass fitted with a bent endpin. The modification shifts the tilt of the Cradle to compensate for the way the bent endpin changes the footprint of the bass/Cradle combination. Be absolutely certain that your bass is stable on the cradle after the modifications. Of course, even though this modification is easily done, you do this at your own risk.
