Hey Old Guy! I have used the oven many times with out any problem. Just some of the tar that they used to cover the copper pipes on the out side of the inner metal box that I couldn't get off with out loosing some finger on the sharp metal corners. Once the tar burnt off all is good and I have had it up and running for hours with out the sides even getting to hot. Just warm to the touch so all is good. :)
I will be using it a lot next year as I have a great deal of parts to do for my 56 Chevy Step Side Short Box pick Up Truck I just picked up in June 2013.
Well did the PC Ovens burn in test and, as I thought no problems to reach the 400 degrees mark. Works great and hold the temp just fine. There was a little burn off smoke as all the excess crap from finger prints and some of the tar on the inside lip of the tub that I didn't get all off. Besides that all was fine.
Just is case anyone was asking how it turned out. I will be doing some PC in the next week or so, if I have the time.
I'm still in the process of building my Recording Studio in my basement and this as taking up much time.
Just wanted to fill in any of the blanks of the PC Oven build.
Hi there old guy! The old freezers have the good old glass insulation and, should stand up with no problems to the heat. I have done much research on DIY oven building and, came across many of the guy's that have used the pink insulation with out any problems. So I should be good and, that is why I will be starting it out side the garage. Just in case there is any problems. :) That is the fun in DIY build it try it and blow/burn/break things up. Hopefully not though!!
Like they say! You never know until you try!..but I always add (use your head)!
Thanks Buddy and be safe!
I just happened to view your oven, I have very limited knowledge on powder ovens but to my understanding you need a high heat insulation as 400 is on the high side. I have used a foil faced high heat insulation around a wood burning stove and it was a little pricey. Just mentioning.
