Greetings all; I took that oven apart today, and found that the thermostat is limited in quickly done adjustability as the knob, as expected is a fine thread with a pushrod pushing on the snap action switch. And its mounting screws were loose on the back of the body of this thing, my guess is enough to cause it to run at least 25 degree F cooler than the knob was turned to.
So I tightened the screws up solid, and put it back together. Put the first brass gib in and set it for 450 & stay on. It hit about 435F before it started cycling. That stat has two thermal gizmo's on it, and I assume that is what causes it to cycle when it has reach its max design temp. Since the stat is not IN the oven, but in a separate compartment that will have a fixed percentage of the oven temp on one side, and the black outer cover on the other side, so I see two ways to make it run hotter. one could put a small fan from an old CPU cooler, with an adjustable speed control, so as to spot cool that end of the oven, or simpler yet but not adjustable, some small holes drilled into the compartment to allow some cooler air to enter and exit. I am rather partial to the fan idea. But right now its sitting crossways on the Sheldon since theres nothing handy to start a fire there, with the first gib that didn't get the stress relief at about 405F from the previous cutoff in it, sitting at about 420F which I'll give it to about midnight, maybe more. It cutoff about 40 thou wide on the ends, and all I have to is lay it on a file & it curls up into the fetal position in fright. After 2 hours of draw filing, first on one edge, then of the other, it warps just from skinning a thou off it with a file, So there has to be a better way. I'll go shut it off about midnight if I'm awake but maybe later if I have to get up and pee. The curse of 81 and diabetic. :( Now, to go and ask my lady what she has in mind for dinner. She had a migraine the last time I asked as I headed out to check an empty mailbox, then decided to finish tampting the first post, put the rails back in, so that job is done for the year, haul the wagon with all the tools in it to the back yard with the rider, and close that gate you can see on my web page. And if I don't mow tommorrow, I'll have to find somebody with a sharp scythe. But everybody around this neck of the woods buys gas for their scythe substitute. Darnit.
