Hi All,Preliminary testing of my annealing oven are good so far. I do not have the controller system in place yet, so I simply feed power to the elements and the circulation fan. I placed identical objects in the oven and hit the power. I found that the parts were different temperatures, but soon realized that was because I do not have a controller method. I then tried a new approach-I hit the power again for for about ten minutes then turned off the elements but left the fan running. After about 15 minutes I tested the parts inside and they wear almost identical in temperature. I also tested the wall temperatures all over the oven and they were also extremely close to each other. I am quite confident that I will have a good even anneal. My engineer friend is also making a temperature tracking system to ensure the anneal is to PVHO spec.Hank
