Panoz Esperante GTLM Race Car Cages

After having some quality issues from another supplier Panoz contracted me to build the cages for the last few Esperante GTLM race cars.  This is another “from CAD model” project – I was contracted to build a fixture and then build the cages on it based on a single 3D CAD file.  The real daunting part of the task was knowing Panoz has a Faro Arm CMM that can measure positions on parts to 4 decimal places for QC inspection and I only had tape measures and straight edges available to build it!  Nonetheless my cages were accurate, and the welding was a big improvement over those of the previous supplier.  (it’s usually a good idea to weld the entire way around a tube joint in a roll cage!)

Lots of pics on this one – some at my old shop and some at Panoz.  In the full chassis shots pretty much any round tube you can see was made and welded by me…
