Hi ,

I have now probably used one and a half hour on net trying to find a 50 degree bevel router bit.
Nobody makes them. Or at least I cannot find any who does.

This made me think twice regarding my drawing that shows a bevel on 50 degrees for the Altec 604 E speaker.

Looked a second time on the mounting template earlier linked in this thread.
If the 604E is catergorized as an early 15" frame then the bolt circle is 14-9/16 instead of 14-3/4 as I thought.
This means that the CORRECT angle is 60 degrees. NOT 50 as previously posted.

And yes they do make 60 degree bit heads .... ; )

I also wanted to tell that I?m quite sure that I will not build the front panel with the round edge, this is because I then have to buy three plates of birch x-finer instead of two. maybe at a later date I will buy a third plate for this project, but not right now - since I want to have the possibility to do so I will place the speaker in the position shown in the 612 DIY cab, not as in the 612C.
