    Am I the only one that puts a PID on his oven?

    So I have a cheap Hamiltonbeach (WallyWorld) toaster oven to cook my bullets. I think I paid the Rain Forrest $50 for it. I'm wedded to Hi-Tek Supercoat so I'm convinced that accurate temperatures are critical. The oven has no useful thermostat so I hook a PID to it. It works great.
    Here's my concern. The PID constantly cycles the oven on and off to keep the temperature. I mean it flips it on and off every 5 seconds or more.
    Is this constant on-and-off going to kill the oven? Or cause overheated wires or components? I mean it's not exactly Swiss quality.

    I have sold many PIDs to people that use it to control ovens.
    Ovens that have mechanical controls wont have any issues but ones that have electronic controls might have issues.

    Good to know. I'll stop buying fire extinguishers.

    I use a PID on my pot and my oven. I put a K-Type connector on my PID so I can just swap sensors for my various needs. My oven was a $10 find at the Salvation Army. It's small but it can do about 200 boolits at a time.

    I drilled a hole in the back of my oven and ran a sensor in there. I was surprised to see how completely off not only the oven was but also my cheap thermometer I put inside it. I would have thought my 99 cent thermometer would have been better than my $50 oven.

    I had a PID that only read out in centigrade, no option for Fahrenheit so I put it in my convection oven...a Chineee'liar oven it was...



    I used a kitchen analog thermometer to monitor the heat in the control area of the oven...thinking that these components will likely fry in there next to the oven but I added some insulation too....
    Then I added a computer fan to the side to blow ambient air directly in the control area...hoping to mitigate a melt down in there.

    PID in cheap wally world oven

    mounted in a separate box, not inside the oven's enclosure

    C only--cheap PID off ebay; set to 207C = 400F

    has been working for over 5 years without a problem

    Mine's been working for a while and it is what I would call "accurate". But it ain't plus/minus 1 degree. It might be 5 degrees but that would be the absolute best.

    Many PIDs out there-- it's just a question of what makes you feel good about your results. I don't use one, but I always set the oven to the exact same setting, keep the batch size the same always, and the time the same always, and always use the same type of powder.

    I understand what you're saying and I may be wrong in what in my understanding of things. I use Hi-Tek Supercoat, which is kinda sorta powder coating but with some very significant differences. My understanding is that precise temperature control is required more with this stuff than with normal powder coating. I know for a fact that if the temperature is off you just wasted a lot of time and likely have to throw the bullets back in the pot for a re-do.

    No mine has worked for 8 years now. Wire fan to be running continuously though so it doesnt go on and off with the oven.

    I didn't think of that. I may peel back the Chinesium back and wire the to bypass the plug. Hmm...or I could do nothing and wait for it to die and buy another for 40 bucks. Decisions decisions.

    I used a PID controlled oven for hitek but don't do hitek anymore. Actually tossed the oven (into trash) for a hot plate - S&B PC and cook on hot plate.
    Whatever!

    I can't cook so that option is out. Last time I tried I was Googling the number for poison control.

    I am experimenting with Wet dipping Powder coat. Hopefully test them tomorrow.
