The Silvertone arrived:
It sounds incredible and plays very good as far as I can tell. I'm a happy man. Also, the Certano Bender already arrived. Fantastic piece of craftmanship and David Certano is a super nice dude. Highly recommended.
Now, on to the project! I got a 4mm aluminum plate and went for it.
Sawing:
Filing:
All the pieces together after some drilling:
Test fit:
Now, all that's left is to drill two holes in the plate, cut threads in it and mount the Bender with two short bolts.
I debated to get a thread drill and all the tools and bits and pieces and do it myself, but it's expensive and not exactly easy to do and so I decided to go to a locksmith tomorrow and let a pro do the job.
So far, I'm very pleased. Looks like it's going to turn out just like I had planned.
