Yes, mine works well...lessons learned.
use only OUTSIDE---- kinda obvious,but the laundry room still smells funny.
Do Not PREHEAT THE OVEN,load the parts, then turn it on. I scrounged an industrial timer, so I don't have to babysit parts ,
Don't trust the numbers on the dial,spend the $3 on a good oven thermometer,use it to recalibrate the dial.
Don't open the door to admire the work. Can cause cloudy spots.
Paper/cardboard burns at 451 DEG. but it smokes a lot sooner than that... use sheet metal to hold small parts.
Don't EVER use that oven to heat food/coffee etc.again EVER !
when you burn out the element(and you will, I'm on my third oven) trash the oven with a hammer so It can't be fixed at the goodwill or by some yard sale buyer, the residue that builds up on the heating elements is TOXIC..............
