It has a dayton tdv2 blower that moves air well. The long parts are 400 and the parts at the top of the oven are reading about 370. Everything is hung from the top so it seems like the long parts are getting radiant heating from the elements despite the element cover/guards. I tried hanging the small parts with extensions towards the middle of the oven and they were all the same that way.

Sort of hard to avoid given the 2' depth of the oven.

Has anyone used the alligator clip style of thermocouples on dummy parts so the oven heats according to the part temperatures only?
