External access for probes

Postby aris » 24 Aug 2012, 12:37

Has anyone done a mod on their smoker, or added a hole for a probe of any sort? I'm thinking of using an engine grommet. I suspect they are designed to handle high heats. If I use one small enough, no heat should escape.

We used grommets from Cajun Bandit for our WSM the process is documented here, a pretty pain free experience.

Its really just a copper pipe thats been opened at one end so its got a wider opening. Then there is ring that you slide over this pipe that can be locked, as a result it does not move once you have mounted it.

Dont know about flesh tunnels, but if you want a do it yourself, this will do - Threaded pipe, cut to size and 2x screw either side.

I've got my probes. I'm going to try a rubber grommet. If that doesn't work, I'll try something else.

Really? What temp is the rubber rated to? The outer edge of the wsm gets the brunt of the heat, as will the grommet, I have recorded temps of 400f+ when putting the lid on my smoker, though it quickly drops down.

Good point - I will have to get a silicone grommet rated to 250C. Might prove difficult to find in small quantities though - so in the meantime I'll use a 5 or 6mm brass compression fitting, and stuff the hole with a bit of foil if I find it is leaking too much.

Good thinking. I wouldnt worry about it leaking too much. There is significantly more draw from the top of the smoker than there is from a little hole in the side. Since I have installed mine I hardly get any heat/smoke leakage out of it. There is more lost around the edge of the door and the lip of the lids. Let us know how you get on & pics please!!
