Hi Steve,
As I'm living in Europe I've to convert your drawing to our standards over here.
First I draw all the parts and connected them using pro SolidWorks 3D software.
I found some minor errors and therefor the placement of the internal panel is not very clear to me. Will you give the distance from the bottom of the internal panel to the bottom of the cabinet and to the rear panel?
Page 6: the gap between the internal panel and panel 7 is different from the distance mentioned on the next page. Which one is correct?
Given the data from my SolidWorks drawings I read out 14.2 degrees instead of 15.6 for panel 6. We can't make it that accurate anyway.

Thanks for sharing this great design with the crowd.
