    Re: Probe ...where to stick it!

    I have the probe about 10mm up and 10mm from the side of the bin, have shortened the paddle by 7mm.

    Probe goes through a large snug fitting grommet in the outer casing, this stops it vibrating out.

    Probe goes through a collett (bush) in the roast bin this allows movement without chafing the probe, also the probe is quickly removed when roast is finished.

    Hope this helps

    Cheers Gazz

      Nice work Gazz,

      Ill get my DMM on the weekend and so will work something out.

      Im still aiming to mount it from underneath, but having looked more closely I can see the challanges.

        I have about 6 different holes drilled in the side of my BM to allow for different roast weights/heights.

        I prefer the TC to be about 1 - 2 cm below the top level of the roast (when the beans have expanded near FC)

          With the probe positioned as in my previous post, with 300gm (see photo) the probe is just under the bean mass.

          Of course as the beans expand toward the end of the roast the probe is well under the beans, which I think gives consistent results.

          A 500gm roast gives a little more cover, but the result is very similar.

          BTW I am using a square bread pan, so a rectangular pan will need a different approach, depending on bean volume of course.

          Cheers Gazz

            Thanks all, thats cleared everything up!

            The paddle on my BM goes all the way to the edge & thats where I was getting confused :-?
