I think I finally found out how to embed the video. Hate to duplicate the video, but I can't edit my previous post.

Update: the Wiper motor did not last. After 20 or so roasts, it started making bad bearing noises and slowing down. Too bad, it was running well.

Upon opening the wiper motor gearbox I find plastic gears! I think it was a GM wiper motor.

There was an AC motor that Lylabrown mentioned in another thread that I just ordered. This one is 50 RPM and looks stronger and better made. Hopefully no plastic parts there... http://www.surplu...e=electric

Really enjoying this roaster and started using the RoastLogger software which looks like a winner. http://forum.home...ad_id=2564

I need to add something to keep the turbo oven from shifting around on the ring.


Some folks make a homemade gasket for this, using high-temp RTV which is supposedly food-safe after curing (be careful to read the fine print on the tube you purchase to be sure):

EMI Supply sells high temp 600'F Food grade RTV. :P

I bought mine from U.S. plastic for $11 shipped. See my other post in this forum for the link. it's good up to 500 and food grade. It was recommended from others at CG.

I did use the US plastics seal for the top of the ring and it works very well. The EMI tube RTV is also useful for adding a bead to the bottom of the spacer ring once it is in place.

Jack,

I also roast with a Stir Crazy and Turbo Oven. I replaced the center shaft with a pen making bearing. It has a 1/4 hole in the center and I pressed it into a hole that I had drilled in the bottom plate of the Stir Crazy. This keeps the shaft from wearing out.

I also added a gap in the aluminum ring that is recommended as a spacer between the Stir Crazy and the Turbo Oven. This allows the air flow to push the chaff out of the roaster and not burn. I pretty much run the roaster at full temperature for the entire roast. It take about 12 minutes from start to finish. I have used one of my roasters for 6 years and roasted hundreds of 3/4 pound roasts. I just built another one so I could rotate roasts and not spend so much time roasting.

Lived in Papua New Guinea, Been roasting for 8 years, I use twin Crazy Stir/Turbo Oven roasters. Now live in Sanford Florida.

Welcome to Homeroasters Phil!
Nice setup with the two roasters. I would like to see that shaft mod you did. Do you use the original stir crazy arms or something different?

I did a lot of tweaking of the arms and motor shaft. ended up using Stainless steel welding rod with stainless steel springs over them.

Nice to see another turbo roaster!

Nice site and roaster Kosmo! The more I read about infrared roasters you guys are building the more I wanna try one myself. Possibly replace my current stovetop roasting. :p Whats the max batch size you guys have roasted? Anything close to 2.2lb?


Hi Burner0...,

The standard TurboCrazy roaster can do about 300-400g with some modification of the arms.
Paul "Koffee Kosmo's" KKTO roaster uses the same turbo oven but a much larger roast chamber, stronger motor and better agitator. I am not sure the maximum capacity but I am sure it may be close to 2 pounds.

I help people build roasters with whatever they have on hand
But the concept is the same

The roaster batch size is governed by 2 things
Overall roast chamber volume to the available heat generated by the standard Turbo Oven without any modifications

One can roast up to 1kg however the roaster is optimized to roast 700/800 grams with a little practice

If one was to tinker with lower roast chamber volumes and stop the Turbo Oven from its on/off cycle one can roast over 1kg

Having said that I recently helped a follow enthusiast to build a dual heat KKTO
It utilities a round electric skillet
Some parts from the KKTO shop e.g. - Shaft, Adapter ring koffeekosmo.com.au/components/com_virtuemart/shop_image/product/resized/Stainless_Steel__4c2d66c1c0cbd_90x90.jpg
Some parts from the Turbo Oven

And build a base with timber

See photos
