Very nice work, Kevin! I have this same dryer and am not at all surprised to see the temp readings you're getting. Having never had a positive-pressure dryer before, I was appalled at how the machine dried clothes. It is an adequate dryer for anything not containing elastic or synthetic fibers as you mentioned, but be careful at the highest settings as I had to re-wash a couple of loads in the beginning to rid them of the scorched odor of the Westinghouse kiss of fire. I was lucky with mine as I found all New-Old-Stock rollers, bearings, etc. but as long as the drum is running smooth and at a steady speed, you'll be just fine. I think I might have that dial, I will look tonight. Shoot me an email and I'll let you know when I have a chance to look.
