I hope you will keep an eye on your P II while you're using it for roasting. In that case, just bypass the thermal fuse and set the thermostat higher, if you can figure it out. My P II has never cut out on overtemp, so I haven't ever taken it apart. I've never tried to roast more than 40g of beans at once. Same with the FreshRoast. I'll open the P II and check for the thermostat adjustment as soon as it becomes less late... Cheers -RayO, aka Opa! Got Grinder?
Ray, I have had a couple poppers that would turn the greens to brown and then stop roasting. The "fix" was to remove the fish-scale bimetallic thermostats, which I believe you are recommending against. Is there another way to prevent the poppers from cutting out part way through the roast?

Saw a new Poppery 2 in a box at the thrift store this afternoon. I didn't get it but it was $6 and change. ********************* Ed Needham® "to absurdity and beyond!"http://www.homeroaster.com(include [FRIEND] in subject line to get through my SPAM filters) *********************

I'd then split the main heater off from the voltage dropping heater and fan circuit, so I could kick the main heat on and off with the switch (fan and secondary coil always on when plugged in). I've since upgraded to the original Poppery, and will NEVER look back. The original is much better for several reasons, including a better 120VAC fan, better heater coil on a better former, better internal electrical connections that make it much easier to modify... I think I must've gone through at least half a dozen Poppery II clones in the last couple of years. And each time one burnt out, I had to modify the new one.
Add a tablespoon more beans, then try it again with more until you like the roast-it will roast faster, but you'll get the beans to start cooking themselves. I roasted that way for months before I started hacking. It's amazing how a spoonful too much or too little will burn your roast before your eyes or not allow you to ever hit 1st crack. My roaster was 1250 watts. You can stir the beans the first minute or so with something that can withstand high heat to get the beans moving until they are light enough to move on their own. You can also split the circuit and put switches on the fan and heating element. That's what I do now and have complete control. --- Brian Kamnetz wrote: <Snip>
...and the original Poppery is built like a friggin tank.
Well, I 'modded' the thermostat so it is open all the time. The popper NEVER heats up now. The brass is too springy to go back to it's original (closed) location. Looks like I need to find another P2 or P1 and start over. All in all, this is fun- tinkering like this. It's a means to an end, and I like working with tools as much as I like turning green beans into Full city roast.

In my opinion, the user can "soup up" any machine he operates. The only caveat I would offer is to keep your eye on the device if you defeat any temperature limits. Thermal fuses should be defeated outright. I equate them with flies- just a useless bother. Forget about warranty- you're only interest is in the prevention of the fusion of Aluminum and Plastic machine parts with your coffee beans, and the production of toxic fumes or flames.

Can you just bend a bunch to make contact somehow? Like take some needle nose, grab it in the middle and twist to make it touch again? That's how I did it when I did mine. Doesn't have to look pretty, just has to touch. You can also take a piece of wire and bypass the thermostat all together. Just have to wrap it securly on both ends where it connects. No solder, it will probably melt and fall off. I've seen the red wire that supplies the fan be used for this purpose, assuming you've split your circuits. Finally, when I did mine, I read somewhere to tilt the thing on it's side so the little disk falls out-reduces how much you have to bend the other piece. ---- Tom Martin wrote: <Snip>
Don't bend a bunch- the sheath would tend to work-harden and kink. Snow good, as Fox used to say about certain neophytes trying to match his organ pedal technique. Bend a little- Do it right the first time Surprisingly, you can bend a sheathed probe on a radius = its diameter (2= r). Some Omega probes survived my bending them around themselves (radius = radius), not 2r. Oil shale retort temperatures (500°C+) aren't much highe= r than Coffee Roasting. Like the retorts, how about an anaerobic roaster? I'll have to learn how to weld or use stuff I can modify. The latter is my style, as I dislike fire and sparks.
