Just to be clear! THIS HAS NOT BEEN TESTED YET For those of you that dont want to pay out of the nose for a small plate of aluminum, here you are. Take this to a metal shop (water jet being the cheapest I have found) and ask them to cut the DXF. Holes are drawn at Ø.275 because that's what the gasket measures, if I can figure out the bolt size used to attach the plate I can shrink the holes to better fit the bolt. I traced the plenum gasket and drew up a plenum plate. I have plans to get one cut at a local shop as I can get a good price. I figure I would share my work with others so everyone has more options! The Plenum Pan Scale.pdf is on 11x17 paper and make sure scaling is off if you plan to use it as a template, I included a 15" line to check against so you can verify it printed to the correct scale. One Drive Plenum Pan Link If someone gets around to doing this before me let me know how it works out as I have NOT made one yet. Enjoy!
