A Crema member contacted me by telephone after he visited Barazi - Bezzera Australia
He had a look at the demo model owned by Chris and offered money to buy it

But alas it was not for sale
We'll after a few phone calls and a little arm twisting I offered to make one

The preferred Arcosteel Pasta pot set was supplied
And to complete the build -
Some parts were used from the Koffee Kosmo shop
Parts that are no longer available were invented or manufactured with home tools and made to fit
Other items needed were purchased

For those that are interested - this thread will be a start to finish compilation of the build

The first step is to drill the pots

Then cut the high temperature insulation that sits under the false floor plate
Afterwards cut the plate and use high temperature silicone to secure
I used a DIY bush circle scribe to mark the circle line on the aluminium plate

The roaster is designed to work best with a specific volume and by raising the pot floor one is reducing the volume

Now it's time to start the base
In this case I used what I had on hand - A circle of 25mm MDF

I also purchased some caster wheels to fit on the underside of the base
This serves as clearance for the motor that is to be fitted a little later on and for mobility

I have also made the connector for the 12 Volt power supply
And you will see some parts like the drive shaft and a dual agitator blade that I will fit and adjust to suit for coupling

Ok the next step is to fit the drive motor and the wheels

Then do the auto centre guides
It's preferable to glue and let it dry before adding the screw

While that's drying the next step is to cut and fit the high temperature tubes
These tubes prevent heat escaping from 2 areas
The join of the two pot sections and the coupling of the turbo oven

You will also see that I have installed the agitator blade ready for testing and roasting

Hi fellow members, I am a new member on this site, I was previously a member on another site which I will not mention.
I would like to give a huge thank-you and praise to Paul (KK) in offering to make my KKTO.
As I have a very sick wife at home who had a major stroke and could not find the time to build one myself, as I am her full time carer.
What I have seen so far has absolutely impressed me. The workmanship that Paul has put into my KKTO is a credit to him. I have never been a person to heap praise on someone that I have only met once, but in Paul's case there is an exception. Thanks Paul, I can't wait to try it.

Welcome Gouly.

How come he gets the flash agitator and you give me the funny one ?

Welcome Gouly.

Three reasons

1) It's to big for your roaster insert
2) It's set up to lock onto the perforated insert ( yours is inverted )
3) You are driving your roaster clockwise and it's my set up is anti clockwise

A simple " because he is paying for it " would have sufficed

Gouly · « **Reply #11 on:** 28/06/2014, 06:14 PM »

And he expects to pay for it too!!!!!

Koffee Kosmo · « **Reply #12 on:** 01/07/2014, 10:35 AM »

Prior to finishing the next step all items were mocked up for good fit
Then all attached items were removed and the MDF was sealed before final fitting as seen below

Next step is to connect the 12volt wiring and connector
All nice and neat

Maiden roast of Gouly's roaster
700 grams of Colombian Bachue 18

Great results to second crack

And the chaff collection works as it should

My hope for this thread is to inspire others to build a KKTO roaster
YES - Some DIY skills are needed however once built, one will have a great roaster design that will just roast beautifully thousands of times for its maker

Result KK ! Roast looks tops. Enjoy Gouly

Gouly · « **Reply #20 on:** 01/07/2014, 09:54 PM »

Thanks Derrilex, Paul did a fantastic job,

I hope one day, I can roast coffee 1/4 as good as he can.

You don't need to do anything - just let the roaster do the job
Easy - just load green beans and cool beans when done
Then enjoy

Saw it in action today. Goes very nicely despite and older element type TO. A new halogen unit and Gouly will be roasting like a, well, trooper

Gouly · « **Reply #23 on:** 02/07/2014, 06:38 PM »

Yes very impressive, I am like a little kid with a new toy, I can't stop looking at it. Thanks for your valued information today derrilex. What was that brand of halogen cooker again thanks.

Not sure if you will find this brand
Highlander

You can also get well priced Turbo ovens at -
Homeart
Aldi
Online from various vendors

They are mostly halogen and shine a light on the roast when it cycles on
