Thanks for an answer how would you actualy put it in? Just straight solder or you use some special reducer or something else?

Silicone grommet?

Still not sure you need it.

If I did mine again I would solder in a small piece of small diameter rod drilled with a bit along its length but not right the way through to make a kind of closed end Port then assemble the arm etc but I already assembled the whole piece so I simply drilled a hole the same diameter as the probe and inserted it ......tight fit.....then I pop a blob of play doh so stop any possible leakage around the probe.
Works for me.

I take the point that it’s not absolutely needed but I find it very useful in stabilising the temp when using the controller so that I can seperate the cuts jars so for example everything up to 80degrees I count as fores

Hi I'm looking at ordering the pieces to make one but unsure if numbers 2,3,4,5,6,7,8,are they 22mm ? Thanks

If you really what to go 100% use a bolt together thermowell...and poke a bit of copper scrubby in the end if you are using a glass thermometer.

I see your point about stabilising the temp when using the controller - but might be better served with a energy meter. That said, for the little extra work, it can't hurt.
Probably help you get to the sweet spot, and once your have run it a few times you will use it less.

My still is different to a T500, but I soldered in a short length of open ended tube to the top of the column, pushed a thermometer probe in and sealed it with HA6.
I find it useful.
