Lack of temperature stability on a Bricoletta - will PID help? - Page 3

[kanoyu]

The following data was recorded following a flush to 205.7 (206 was target) deg. F and a 40-second pause from long idle (tc registering 212.8 deg F). The pull was 26 seconds and measured by a tc device and Scace thermofilter simultaneously.



The tc range was 205-204.1-205.3. The Scace range (after the first 6 seconds) was 203.4-203.8. Needless to say, this does not look much like either Dan's or Eric's charts, and is why I noted earlier that I did not get the temperature variance of 5-10 degrees F that others had noted. Nor do I get much of a hump despite a long flush (50 seconds and about 10 ounces) and a 40-second pause.

I have not yet taken measurements on successive shots, and these might prove revealing.

edwa, I don't know if this helps, but I hope it gives some relavance to the routine that I outlined earlier. As others have noted, the actual numbers are not that important, but the routine has brought some stabiity (on the first shot, anyway). I am going to (try to) ditch the meters, etc. as soon as I can fine-tune my sensitivities and solidify my routine. I hope your 'good enough' is very enjoyable!

kanoyu, thank you for the kind thoughts as I sit here enjoying my morning cup a. Thanks for the graph besides the surprise of how close the tc & scace are I was taken by how your tc temp is increasing at the end of 27 seconds. I like you get more stability over the length of the shot from the first pull.

thanks again.

Where (location) was the tc device - over the pf lip? nose bolt? ?

nose bolt, per eric's instructions (or as close I can could get to following them!).
