Big-block header flange template

#1
I was sick of seeing price tags of $10 or more for exhaust flanges, so I drew and modeled a 3d file and SVG file to use as a template to cut and drill your own. I work at a metal fab shop and I have access to a CNC plasma table and laser cutter as well as cheap scrap metal, so that makes these trivial to make. If you have a CNC mill or cutting table, you can use the SVG to make your own. If not, you can print it out and use it as a template to cut it out with a grinder. Just print and cut it out, tape to a piece of metal, cut and grind until you hit paper. Then drill out the holes. Or drill it and then cut it, I don't care. For size reference, the center hole is 1.25"

If anyone is interested, I can probably draw one up for a 212 or other small engines pretty easily.

You can find old chrome small cycle mufflers you can cut up make a good looking one. Or make a short pipe and flange to fit the engine the weld a washer on and use a big chrome bike pipes.
