Sorry to come late and uninformed to the discussion. Can anyone point me to plans or URLs with SC/TO construction diagrams? SC/TO = Turbo Oven/Stir Crazy I assume? -- Ann http://home.austin.rr.com/avanderlaan/ _ Round Rock __| |_' "They that can give up essential liberty to obtain a little \_ * _} temporary safety deserve neither liberty nor safety." \_( -- Benjamin Franklin
Hi Ann, Try this page:http://turbocrazy.atspace.com/index_files/project.htmMine's built just like that, but with a different brand of TO (turbo-oven.) The few changes I made include using fewer threaded bolts to hold the chaff ejection chute open -- two will do -- and disconnecting the SC (Stir-Crazy) heating element. Like I said in an earlier post, I'll put the lower element on a switch on the next one. One other detail: I pop-riveted three aluminum "fingers" to poke up and out over the top of the spacer ring. They keep the TO from sliding around. It's worth the effort! Tom in GA
Ann, you can get design specs and more info from a search for "SC/TO coffee roaster." -ro On 5/29/06, Ann Vanderlaan wrote: <Snip> -- "When the theme hits the bass, I dance the Jig!" - -Virgil Fox at the Wichita WurliTzer
Go down this page a bit and you will find all the information you need, maybe too much. :)http://www.coffeegeek.com/forums/coffee/homeroast/232705#232705On 5/29/06, raymanowen wrote: <Snip>

Tom in GA, <Snip> That's a great link. When I started research from Sweet Maria's I ended up with a dead link in the WS domain. Unfortunately as a nerd I got distracted by the geographical location of such a domain. :) The chaff chute seems to be a very elegant solution to my biggest concern. As a EE I would probably also switch out the SC heating element. What brand of TO do you use? ro, I did google for "turbo oven coffee roaster" and ended up with a large number of circa 2000-2 blogs angsting over chaff and such. But no pix. When the SM links came up unresolved I felt like the list was the best place to ask. James H., There is no such thing as too much info. I hadn't seen this thread at coffeegeek. It also has the link Tom cited. I must have petered out in my google ardor. :) Scot M., Great thread Scot. Now I know how to avoid center shaft meltdown, and have an easy method of thermometer mounting. Ya know, we do not have these kind of problems in the oil-drilling industry! Many thanx gentle folks. Now a question. Is anybody concerned about degradation of the non-stick surface coating in the SC? We are certainly operating out of spec for the surface I believe. -- Ann http://home.austin.rr.com/avanderlaan/ _ Round Rock __| |_' "They that can give up essential liberty to obtain a little \_ * _} temporary safety deserve neither liberty nor safety." \_( -- Benjamin Franklin
IIRC, Teflon is a problem when you get it hot. It starts to emit a toxic gas. Techs soldering around Teflon insulation (about 700 degrees Fahrenheit) work on a laminar flow bench -- air blows across the surface of their workbench to carry away any gas generated. I did a google for "teflon heat toxic;gas" and got lots of hits. This was at the top, looks like a "scare site", but maybe a good starting point:http://tuberose.com/Teflon.html.I can't vouch for the veracity of the site, but roasting temperatures are certainly on the edge of what is a problem with Teflon. It would be prudent to have good air circulation. --MikeW On 5/30/06, Tom Bellhouse wrote: <Snip> -- "Life is just one damned thing after another." - Elbert Hubbard
This is a multi-part message in MIME format. Michael, Just my opinion, but the base of the StirCrazy probably doesn't get as = hot roasting coffee as it does popping popcorn. That's especially true = if the base heating element is disconnected. Abrasion by the stirring = rod over time would be the thing I'd worry about. From the FAQ at Westbend; Temperature Q. What temperature does the Stir Crazy® get to during use? A. - The base of the corn popper will heat to approximately 450°F to = 520°F during use. Tom in GA
Is anyone using one of these indoors??? Way too much smoke for that. On 5/31/06, Tom Bellhouse wrote: <Snip> t <Snip> e <Snip> it) <Snip> g <Snip> f <Snip> l <Snip> n <Snip> , <Snip> t <Snip> ttings <Snip> -- "Good night, and Good Coffee"
Starting at about 2nd crack the beans generate heat too. Popcorn never gets to this stage, it is done at first crack.

The smell lingers for a couple hours but it is not too bad of a smell really so I don't mind. The chaff collects in the sink. My wife only has a problem when I roast in the middle of the night after she is asleep. Don
One could always go back to what plumbers did before Teflon tape: wrap string around the threads. They also used a compound w/ the string, but I wouldn't think that would be necessary here... A+ <Snip>
