anyone have the knifedog kiln and did a PID mod to it . not havin real good luck on my alloy steel .doin great with my carbon , D2 but i recently worked 3 blades of AEBL .just little EDcs but i snapped 1 rushing to much on my straiting it after the first temper and noticed LARGE grain growth. this blade was ground 3/4 finished and the others werent as i do all my work post HT grind,cept this 1 and tryed it.
would really like to go PID controled,price to mod and what controller to use.

heat to 1550 or abouts,with the dial controler,10 min soak ,ramp to 1900,there abouts, for 15min,plate.i worked up 1 of the blanks into a 3 1/2 B&T to almost zero edge and it seems to be a good edge .still puttin it thru thru some paces. im holdin off the AEBL til i get PID controlled.my D2 is a real fine grain almost smooth.
thankx scott, that was the info i was needin.all this is new to an old dog like me
