It is now time to start building the framework for the GRV-2. For the most part I will be building the frame out of .060” wall square tubing. This is the same tubing I built the Turbotug out of and also the GR-7 engine frame. The truth of the matter is that this square tubing is cheap and easy to work with. Square tubing also has a higher torsional strength than round tubing which should help reduce frame twisting.
With the aid of my trusty 64-1/4” band saw I chopped up a few pieces to build the rear wheel assembly. Using my TIG welder I tacked together several pieces which will eventually hold the axle bearing hangers.
