Ed, Did you widen all or just some of them? Thanks, Bob Edward Spiegel wrote: <Snip>

Funny thing, I grafted the aluminum roasting chamber from a poppery 2 to a 1440 watt 'screened' presto lite. You know the kind they warn you about??? And wow, because the heating element and fan assembly are supported by a 3 legged plastic 'stand', the whole rig will operate without a shield or an outer plastic 'shell'. I ran it for over an hour, straight, last nite, while I roasted. ( It makes a nice additional heater in a cold shop.) The volume of air and heat available is really awesome. Next step is to add toggle switches and mount it back into a better housing. I want to be able to run a dampening system, much like a butterfly on a carburated (remember those?) engine, to control airflow. I'm just experimenting with what's available out there, but I found 4 more of those prestolites today in 3 thrift storees, along with another poppery 2. So far it's worked well, without melting, sparking or shorting out, so that's a good sign... I am thinking about opening up the metal vents in another roasting chamber and comparing the differences, I was thinking of ways to measure the airflow, any ideas on that, Ed? ( still not ready to hack into one of my 3 poppery (originals) as I feel that it's somehow wrong...I don't feel that way about any of the other machines out there, I've got 4 or 5 of them torn apart on my work bench, awaiting surgery.

I routinely roast with the screen-in-the bottom popper at the plant. I have only seen the sparking chaff once or twice in a month and it went out before exiting the popper hood. The only mods I have made thus far are to drop two 1/2" ceramic balls into teh chamber to help agitate the beans. A 1/2 Cup volume roast takes about 3 to 3:15 to go to starting second crack.

Justin, I know a few other people that run with scissors! I'm just exploring ways to increase the output of normal machines that are easier to locate, namely poppery 2 types and prestolites...they are everywhere, and cheap, usually $2 -3. at thrift stores. The poppery 2 style aluminum swirl chamber is the right design. The 1440 watt heating element and the fan assembly in the prestolite gives you the extra power. A few tweaks, and you have a possible 6 to 8 oz air roaster! So, that's my approach. I also like extending the air roasters chambers, preferably with glass hrricans chimneys, so that you can monitor the roasting from the side view. Nothing harder than smoke and heat blasting into your face while you are trying to get a peek at the roast level ;-O On Sat, 15 Jan 2005 08:05:09 -0600, Justin Marquez wrote: <Snip>
No - They are 1/2" Norton DenStone Catalyst Support media. They are mostly round alumina balls, designed to survive temperatures upwards of 1000 Deg F in a temperature cycling service. We use them at the gas plant where I work as a bed support for our gas dehydration tower beds (filled with silica gel) Safe Journeys and Sweet Music Justin Marquez (Snyder, TX)http://www.justinandlinda.comOn Sat, 15 Jan 2005 06:59:50 -0800, Brett Mason wrote: <Snip>
