The motor is mounted to an old bike rack that is clamped to the BBQ with some c-clamps until I get a more permanent mounting.   The system works very well.  I’ve had a surprise one day when some beans escaped because the lid was not secure.   The next phase will be to get a reasonable lid for the unit.   I like Ed’s funnel lid idea….etc   Ed – thank’s for the inspiration for this via your web site.

Posted Mon Aug 9, 2004, 8:42pm Subject: Re: Ice cream maker turned bbq coffee bean roaster   Dwight, The way I dealt with the issue of connecting the rod to the ice cream motor outdrive was this: I lightly coated the inside of the outdrive stardrive with vaseline. Then I centered my rod in the outdrive. Next, I mixed up epoxy and epoxied the rod to the stardrive. When the epoxy sets, you are able to simply pull the rod out of the stardrive and VOILA, you have a custom fit stardrive connector. I used a 1 gallon green bean can for my roasting chamber and I roast over my turkey fryer. I cant roast more than three cups of greens at a time but I can see/hear the beans during the entire roast. (And, 3 cups is much better than 1/2cup in a popper) back to top SilviasSlave Senior Member Joined: 29 Feb 2004 Posts: 37 Location: Fountain Valley,CA Expertise: I love coffee Espresso: B2(11/06);  Silvia (11/02) Grinder: Rocky 11/02 Vac Pot: Maybe in the '60's. Roaster: TurboStirCrazy Posted Wed Aug 18, 2004, 9:26pm Subject: Re: Ice cream maker turned bbq coffee bean roaster   Dwight-Thanks for the idea about using a sparkplug socket.  I'd been thinking about the linkage problem between the spit and the ice cream motor and was about to try drilling a nut so as to fit an allen screw to tighten onto the spit.  But the plug socket sounds like it would work better.  Now to work out a brace that will stablize the ice cream motor at the correct level.  Tom   Tom back to top Dwight Senior Member Joined: 20 Apr 2004 Posts: 99 Location: Idaho Expertise: I live coffee Espresso: Livia 90 (PID'd it) Grinder: Baratza Virtuoso Roaster: RK Drum / 2 HWP's Posted Thu Aug 19, 2004, 3:21pm Subject: Re: Ice cream maker turned bbq coffee bean roaster   I just completed squaring the inside of the socket to conform with the spit.   I used a file and gave the inside of the socket some shape.  It seems to work great now.   I've been working on making a lid, and am still at a loss for a good design.   I'd like the lid to stay flush with the aggitator vanes, that way I don't have any un-agitated beans.   Also my tendancy has been to lengthen the roast too long.    I'm still getting first crack at 16 to 18 minutes.   ... need more heat.   Regards, Dwight back to top view previous topic | view next topic | view all topics Discussions > Coffee > Home Roast > Ice cream maker...   updated topics   new posts   new unanswered     search   faq   sign up   Not Logged in: log in Discussions Quick Jump: Select Espresso Discussions --Espresso Machines --Lever Espresso Machines --Grinders - Espresso --Espresso Mods and Restorations --Espresso Blends --Questions and Answers --Latte Art and Etching --Barista Jams Around the World --General Discussion Coffee Discussions --Machines and Brewing Methods --Home Roasting Talk --Questions and Answers --General Discussion Columns, How-Tos, and Reviews --Holiday Gift List Feedback --CoffeeGeek Columnist Feedback --Detailed Review Feedback --Products First Look Feedback --Quickshot Review Feedback --Guide Article Feedback --How-To Article Feedback --CoffeeGeek Podcast Feedback Members Forum --Bug Reports and Suggestions --Buy, Sell and Trade --Retail Coffee Jobs Offered / Wanted Ads --Coffee Recipes --Cafe and Bean Reviews --CoffeeGeek Site Info and News --General Off Topics World Regional --United States West --United States Central --United States East --Western Canada --Eastern Canada --United Kingdom --Western Europe --Eastern Europe, Nordic Countries, and Russia --Central and South America --Australia, New Zealand and Asia Symbols: = New Posts since your last visit      = No New Posts since last visit     = Newest post Forum Rules: No profanity, illegal acts or personal attacks will be tolerated in these discussion boards.
