How to build L-300 Grilles?

Hi Everyone,
I'm trying to make reproduction L-300 grilles, that I can offer in all the different and available fabric colors.

I need help figuring out how to build L-300 grilles. I made a deal with an LH member in exchange for an original pair of frames to use as a reference and help in the reverse engineering, that includes building out replacements.

The grille measures 3 1/4 inches deep, almost 30 inches high and 23 inches wide. It's a large frame.

Sourcing the materials is pretty straight forward.

I specifically need help with the edges and corners. The frames are made with two levels, angled at 7 degrees over a 3 inch height, with rounded and angled corners. Tricky to say the least.

I think the factory might have originally built the frames using 90 degree stock, and then when the frame was built out, one of the last steps was a process that would cut the top and sides at the angle and round the corners, using a router or shaping table.

Or, after the frames were built, maybe a combination of table saw with at least a 12 inch blade for the top and side angles, and then a shaping or router table for the corners. The table would need to be angled or a template to angle the frame would have to be designed for the correct corner radius.

I'm prepared to make templates for repeat ability and consistency to build dozens of frames. I can't get me head around the process and tools needed to get to the template design phase.

Thanks in advance for your thoughts, ideas and comments.

You're right. The corners are tricky. I'll email you. These are the ones I made from scratch last year.
