Haynes Roadster Frame Alignment Squares

thingiverse

I'm crafting a Lotus Seven replica based off the Haynes Roadster plans outlined by Chris Gibbs. I've discovered that printing various tools to aid in layout has significantly accelerated my progress and substantially enhanced the quality and consistency of the required material cuts for the project. I'm utilizing these squares to help secure frame tubes to the build table, also useful for creating jigs and fixtures. They feature a bit of relief in the corners to account for weld bead that will result from tacking and welding the tubes together. These alignments are designed for #12 wood screws, with an 82-degree cone on the screw heads. I have included the parameterized Fusion360 file.
