Dave made a couple mock up pieces for the center section of the firewall last week.
He wanted to make sure it was exactly what i wanted before he went any further on the Firewall. Seems he was afraid of a fourth Firerwall.
Here you can see the two mock up pieces so we could decide which we liked better. We choose to go with the 1 1/8" deep version.
Here is what it took to make the part from beginning to end. (30 minutes total)
