Even though I am a believer in manufacturers gaskets. At times, I am really disgusted with the price. Well, for simple gaskets like rectangles, does anyone make their own. This goes for any stove. Do you use just a Mr Gasket automotive style material? Or do you cut silicone rubber sheet? Thin Asbestos sheet? There are just so many gasket materials out there. I also wonder if it is possible to even identify the material type used in a gasket today. I typically dont usually make gaskets that are more intricate with punch holes, but rather think of duplicating simple shaped ones. I only ask because, generally I am not opposed to spending money on a necessity like a gasket, but it seems like the pellet stove industry, just like the automotive industry is ripping people off by overcharging on a simple cutout shape.
