I actually didn't do the rivet vent therm mod for the therm to be mounted it was kinda by accident and out if necessity, my 26er's lid area by the vent and the vent itself were in bad shape. So to reshape them I removed the vent and for a temporary fix I mounted the vent with a rivet I had at my shop. Well bring it home and I have a spot to hold my instant read therm(kinda nice like a MT therm) while cooking. Plus since my 26er has the lid therm I really didn't need this but this therm does get closer to the grate. It has been interesting see the difference in readings from the lid therm to my instant read through the vent and the oven one I place at the grate, now with my Xmas gift from the girlfriend (ET-733) I can really experiment and see how each behaves differently. Was going to replace the rivet but now there is a lot more experimenting going to happen. All in the name of science and filling my belly with good food!
