I put the 8 degree bend in the top of the firewall per th plans and then I dimpled all of the #30 and #40 holes called out in the plans being very careful to not dimple the F-801L holes that don't need dimples. I then started countersinking the structural parts.
8 degrees on the top of the firewall.
Dimpling the firewall - note the gloves, the stainless steel is very sharp.
