This is how anal retentive I am. I spent an hour making my frame rails as accurate as possible. Ugh. I need to heal faster or I'm going to end up modeling the stitching on the steering wheel cover.
You really don't realize how big everything is until you start measuring for scale renderings. I had plans to replace the rear tubular bumper with a section of frame rail, but these things are 10" tall by 4" wide and at least 1/4" to 5/16" thick. I think the weight of an eight-foot section would drop the rear of my bus an extra inch.
(Would look bad-a$$, though.)
