Made a test bend with the new pittsburg bender just to see how it worked before modifications. The new tool flattens the bend and I am going to return it. The box still says 1/4", 5/16 and 3/8". The tool has a molded in description of 6, 8, 10 mm. I measured both the old and new tools to confirm and sure enough the old one is 0.375" and the new one is 0.394 (10mm). This allows the 0.375" tubing to spread sideways and flatten instead of maintaining a round cross section. The tube in the picture with "new" written on it is the one that is flattened. Researched other options and ordered an OTC 6515 bender that Amazon should deliver tomorrow. I also spent time researching panel layout and preparing for Airventure, but didn't include any of the time in this entry. I hid a bunch of columns in the Garmin configuration and pricing worksheet and printed it so I will have it for Garmin and Stein to review and comment on configuration options. I also found and printed two good drawings to use as the basis for showing component locations.
