Acoustic Guitar Construction

Should I use your "8 3x5" to adjust my rim in the mold to sand the neck block angle or not.
I have already followed this part of your instructions and I need to know if I was correct by adjusting and sanding the angle on the top of the neck block or do I need to make changes before I glue the top on to my rim.
Thanks in advance,
Andy

As long as the neck you are using has about an 88.5 degree cheek to finger board plane angle you should be fine.

Thank you again !
Andy
