I got a 3 inch dial 4 inch stem thermometer for a early birthday present last night. I acted happy to get it and I know they want to see it on my smoker. But where should I mount it? It seems to long for the center section getting in the way of lifting the grate out with handles, it looks to long for the lid with rolled spares or beer can chicken maybe not though.
Anybody happy with this size? And where did you put it.
Here's my opinion and it's only my opinion, YMMV.
I have three issues with a 3" dial face therm on a WSM.
1) These are better suited for large offset stick burners are are way out of scale on a WSM.
The OEM dial faces are 1-3/4" diameter.
I would go 2" max dial face although that would not fit the Weber bezels if you want that OEM look.
2) These larger therms make you punch a large hole and this can be avoided with a smaller therm.
3) The stems on these big therms are often too long to be practical.
2" - 2-1/2" will do nicely for a lid therm stem.
I have seen where folks with poor eyesight will mount these large therms on Webers but they look like a giant wart to me.
Keep in mind that a lid therm will only be a rough temp reference.
To dial into grate temp and food temp will require something like a Maverick.
Here's a step-by-step on how I added a lid therm to an older WSM...
Remove the OEM locator tab
Bezel and Therm
Triangulate from handle strap 5"
Swing an arc from each side of handle strap
"X" marks the spot
Bit selection
UniBit cutter is "Sharpied" so that I stop BEFORE that cutter engages
Hole is started through the blue tape with a sharp 1/8" bit...NO CENTERPUNCH needed.
Go slowly, stay square (perpendicular) to lid and the tape will hold you on center.
You will get slight chipping but nothing catastrophic using a sharp UniBit (carefully).
Third hand (blue tape) is used while flat washer and wingnut are snugged up
Lightly snugged is all that's needed
Job Complete
Weber part numbers for this mod are...
Bezel #63027 (this is the low-pro smooth bezel)
Therm #63028 (correct "smoker scale" therm*)
*As opposed to "grill scale" (I want more detail in the smoker heat range)
This particular weber therm checked out against a Tel Tru so I believe it to be pretty accurate
It will be used for rough reference only and backed up by my Maverick ET-732
Here's BQ100 in a Weber bezel (on my OTG) but the scale is more suited to a grill...
