I'm looking for a better way to "mount" my probe thermometer in my grill(s). I know a lot of people use a hunk of wood with a hole drilled through it. And I'm probably going to do that but I want a little extra support so the probe isn't loosely cradled in the hole. My first question is how big of a hole do I need to drill for the probe to slide through easily? What size bit should I use? Finally, and most importantly, I was thinking about mounting rubber bushings on each end of the hole. That way, the probe has to slide through the two bushings (which are a little smaller than the probe), to make the probe more sturdy in the block. Has anyone tried this? If do, what kind of bushings should I get? Obviously it has to be made of something that could withstand prolonged temps of 300 or even 400 degrees sometimes. My only other concern is mounting the bushings. I would prefer to glue them because I can't think of any other way. But what glue can I use that will withstand the heat as well? Thanks for any advice.
