    I too would like to know if this has been successful, we got a lot of wonderful information from Peter42 above then complete silence! I'm curious as to if it works for 200g loads, the beans whip around all over the place in the drum, and that is what I typically roast. Also don't know if I want to be bothered with the tube, wonder if there is another (lazier) way to get the probe in there?

      I have the bluetherm duo and I use a wire prob placed in the chaff collector, the info does help but it's not as good as a bean temp probe would be. However I did find out that the temps given by the 1600 plus control panel are far different than what I get from the blue therm duo.

      I do believe a bean temp probe can be done however it wouldn't come with out ease and heavy modification. Not sure I'm willing to go to that extent.

      If you want more info on my setup let me know.

        There is a mod on here where the probe was put through the shaft directly into the bean mass. If that interests you give it a search.

          Thanks, yeah I'm comfortable drilling a hole in the side of the drum big enough to shove a probe wire through, but probably not comfortable enough with my skills to drill a circle wide enough to fit the metal tubing as Peter42 above. Don't have much equipment. Also don't really want to drill into the side of my beloved Behmor chassis! I couldn't stand to look at it.

          djbetterly I find under the chaff collector the thermocouple readings are like 50 degrees less than BT. Lately I've just reverted to the wall thermistor, making sure it increments in a controlled manner after 1C, by altering the power settings in manual mode. This has been the biggest impact for me and has helped me to better steer the semi-trailer that is the Behmor, producing more roasts where the first few snaps of SC are heard in cooling and no more, how I like it. How do you find your chaff tray thermocouple readings change between FC and SC?

            Hi, I am not so often online at CS these days, so I didn't follow the thread.
            First, 200g is not really good, as the level of beans is too low. I did typically 330g, which fits good.
            Second, the only lazier way for a probe in the bean mass is another roaster.

            In fact I upgraded to a Huky and meanwhile sold the Behmor as 2 roasters are too many for me.
            I still think the Behmor is a wonderful roaster and loved the beans I roasted with.
            But with Huky you can play around more. Maybe things were different if the Behmor plus version was available earlier at that time.
            Enjoy your coffee. Peter

              Hi Peter...

              You'll have to start up a thread on the Huky and let us know of your experiences with it.
              Looks to be a very interesting little roaster...

              Mal.

                The Huky has been around for a few years now Mal, the problem is that it has no Australian approval for the circuitry an no AGA approval for the gas train making it illegal and potentially dangerous to use here.

                I like the idea of it (with local certifications) but at circa $2k+ landed here (plus the certification costs) it's getting into the very top-end of options.

                  I am really sorry for you, about the legal issues and the gas train.
                  Here in Germany it is a bit different. The original connection to the gas you cannot use either , but you can change and I don't know about legal issues, as long as it is non-commercial.
                  Surprisingly the shippment from Taiwan is affordable compared to Australia (I know it's not your fault Andy), so that in total the price / value here is very different if you compare Behmor to Huky.
                  Nevertheless thanks and compliments for the job an support you give on the Behmor.
                  CS is still the only reasonable source for Behmor and parts for German users.

                    Peter42, thanks for your reply. I did find a lazier way to get a probe in there, you can get these 30cm bendy probes off an online market place, this guy did it: Behmor 1600+ Mod : roasting. Just out of interest, I would never do this, but this dude also PIDed his Behmor bypassing the mechanical relay.

                      It might be a bit lazier without bending the prbe. But the tricky part remains thr drilling of the axis..
                      Some lines below there, the guy is referencing to a CS thread as someone is asking for pictures.

                      I feel I should have made some photos of a drilling template at the end,
                      But I hope I described it good enough how to prepare one.
