Nice work, Bill. Nothing like close-up photos to put a model under the microscope!
The Archer weld lines are a bit wavy, which you have recognized in previous posts. Many years ago, Jim Eager taught me an alternate way of doing weld lines when I was reworking the sides of a Robins Rails 50ft PS-1 model (the only 50ft PS-1 on the market at the time). Jim used a No. 11 Xacto blade to score each weld line on the car side, then went over each weld line with the back of a No. 17 blade. The secret is that the No. 11 blade creates a shallow groove with small ridges of plastic on both sides of the groove. The No. 17 blade flattens these ridges and closes them over the groove, resulting in a 'weld' line. The key to success is knowing how much pressure to apply to each of the blade movements. Experimenting on a scrap plastic boxcar body before working on your super detailed model is recommended.
