Yeah, I was originally planning to solder the end, but after crimping it shut I am positive it won't leak. (Plus, I was out of gas for my torch. )

You mentioned that yours cost $10. How in the world did it cost that much? Does that include the price of the termometer or something?

Nevermind.. I see in your thread that the thermometer was $8 and the stoppers under $1.

I don't recall what size I bought. I'll have to look at the package when I get home.

Following up on this item.... I realized a problem with this thing after using it for a few batches.

The thing is located too high up on my tun. It sits under the water line for a 5 gallon batch but above the grain bed.

The water above the grain is several degrees lower than the actual grain bed, so the thermometer reads a lower value than I am actually mashing at. If I slosh the tun around to get things mixed back up, the temp reading comes back up and is accurate.

Unfortunately, I had to put it where I did in order to be able to get my false bottom in and out, but this resulted in the thing being in an unfortunate spot for my 5 gallons batches.

10 gallon batches have no problem.

Just FYI in case anyone else tried making one of these and was noticing problems with temp readings.

Do you have any issues when stirring? Seems to stick out kind of far.

Yeah, I have to be careful when I stir so that I don't slam into the thing. I end up doing nearly complete circles clockwise, then counter-clockwise, so that I don't hit it hard.

But, any thermowell would create the same issue, so it's not something specific to my particular thermowell.

The probes I am using are fairly short, so I could absolutely cut several inches off this thing and would be able to use it, but I'd still have to be careful when stirring.

You mentioned the thermowell is too high - where would you want it? I assume inside the grain bed. Would directly above the false bottom work (~1/2 inch)?
