I can tell you that even before I upgraded my heat source on my KKTO it was still producing amazing coffee

I have no problems roasting up to 1kg at a time - but I'm usually perfectly happy with 800g

The quality of the roasts are second to none, the equipment is hassle free and completely customizable, and the quantities that you can roast on a KKTO are more than enough for home use

But mainly it's the quality and consistency of the roast that appeals to me most - easily on par with cafe quality IMHO

Enough said ...

I completely agree.  I was skeptical until Paul demoed his unit at a meet and greet and more importantly I got to sample the results.  Now I only use the Behmor for small batches.

So I have built my KKTO and have a question re the kit. The kit comes with the 2 pieces of silicone tubing. Has anyone found that using the lower one (smaller diameter & joined) that the shaft doesn't seat properly/deep enough? Doing dry runs with green beans I found that if using the lower silicone ring the shaft jumps lifting the perforated pot with it. Without that lower silicone ring I don't have that issue but do find that perforated pot turns with the agitator arm.
So far, with my limited testing and DIY skills I have found that I get a better result using the larger diameter tubing slipped over the lip of the lower, outer pot. This keeps the perforated pot stationary and seats it low enough to engage the shaft properly. Hope that all makes sense...

Hopefully my Turbo Oven will arrive by courier tomorrow so I can start roasting on the weekend. Another question, would the weight of the TO be enough to hold down the perforated drum and shaft and hence stop it "jumping"?

Also finished my bucket cooler :D Got an Ozito shop blower/vac that I have mounted on my BBQ to aid with the cooling and it appears that it will work a treat.

Try pushing the perforated pot down to seat it
The lower tube can be replaced with a fine layer of high temp silicone gel/paste (from the tube) where the two pots join
Its purpose is to seal in the heat or to put it another way not let heat escape

This is very possible
However there are a few easy tweaks to fix anything as all the parts need to marry up & once done its permanent, I am only a PM or call away

Okay so I am a few hours away from my maiden voyage with the KKTO.

Any last minute sage advice?

Best tip = do it when there is nobody around.

It's surprising how easy you can be distracted when someone else is there ....even if they are just watching.

I love talking to people and can talk your head off about all things coffee, but when I'm roasting I even hate it when my staff are nearby as they are bound to ask me questions that can distract me.

Good luck Marc and well done taking a leap onto the successful KKTO platform.

I completed my first KKTO roast and reckon I did pretty well. I couldn't be bothered trying to figure out why the CS Roast Monitor would not detect an input HID so I proceeded manually. I'll try Roast Logger instead, at least it detected the Victor DMM.

I reckon the roast went well albeit a bit slower than I'd like and I pulled them a bit earlier than I would have with the Behmor, oh and the cooler got them down to 25C in around 3mins so they are a bit lighter than usual for me.

Anyway, here is the result :) 1kg of Nicaragua Matagalpa by way of Green Bean Coffee. Can't wait to try em out!

They look great Marc!  Welcome to the KKTO club!  Look at all those browns.... The best bit for me with these new volumes is that I can finally have a batch last long enough to drink them over a couple of weeks and enjoy their development.  Great job mate... first of many!

You did a good job as a first roast

What do I say in the instructions   ;)
Start with small roasts and get familiar with your roaster and work up to larger roasts

You went to the deep end first up  ;D
Very rarely do I roast 1kg with standard TO
The sweat spot is 500gr to 650gr, - & for 99% of the time I roast 700gr

How small can these roasters go without the Insert?  I have been too afraid to go under 500g.  I use the Behmor for my 300g roasts but would prefer using the KKTO!

You can roast 100 grams "but" with care to keep an eye on the heat
On the KKTO due to clearance to the side,  the current agitator blade will mix 300 grams but if one puts a dog clip at the end of the blade it can roast under 300 grams

Yes KK, I know you said start smaller but I couldn't help myself. If you'd said start with 250g I would probably have started with 500g - just for the challenge. All was not lost anyway, actually far from it but I did see the value in Borat's SSR mod as thermostat turned off the element a few times unnecessarily.

While I have some fine tuning to do I am already VERY glad I made the transition to the KKTO.

I found I kept tripping the power board when I turned on the TO element meaning I had to run a separate extension cord to the power pack for the agitator motor so I'll have to find my heavy duty one in the garage.

For those who have used the solid and the halogen TO's - Do the Halogen elements get up to temp easier than the solid elements? ie is the heat more "instant"?

Again great advice and great ideas, for free and and with no guarded jealousy or eye-rolling for my noobish inquiry. What a place the world would be if there were more KK's!  Thanks Paul and keep us up to date on your progress Marc!

I also found a few got stuck in the middle.  I used a BIG bull dog clip for the middle, and a little one at the end on one side.  Worked a treat, and I roasted a few batches of 100gm for my syphon.  I also used the extension ring (not sure what KK calls it) at the top to add more volume and extend the roast time.

I have both.  I found roast times where very similar, but the light is a bonus.  I can now roast at night too! :)

Comparing Tiffany (older, S/H) to Kmart Homemaker (halogen, new)

Tiffany didn't switch on/off problematically
Homemaker with guard on switched too much
Homemaker got up to temp quicker and had a smaller dead band.

I think I may have helped you with that same question Lacehim a few months ago
The beta testers got an adapter ring 
However, to keep costs down & to make a fully working roaster more affordable the Stainless Steel TO Adapter Ring  is an added extra
But its not needed for small batch roasting if you keep a close eye on the heat

At my current savings rate, i should be an adopter for the KKTO come Christmas.
                 Koffee Kosmo has been very kind as to send me a sample of his roasted Peru to try. 
I ran a blind test of Paul's batch versus my coretto roasted batch, which was Peru as well.

Two lots of double shots were made on my Miss Silvia, and on each double, one was an espresso, and the other made into a flat white.

Without knowing which one came from, a friend helped to label them A and B on the first round. I tasted them, noted them mentally down and he then proceeded to make the second round, just for consistency in this cupping and then tasted again.

Both times label A as an espresso was better than B. Was sweeter, more flavoursome with pleasant acidity, had more body and poured nicely into the cup, more smoother and did not blond as early as label B. As flat white, both are similar, though label B was a bit more punchier, more bite, so to speak, but not much in it according to my taste buds.

I declared label A the winner, and it was revealed that it was KK's beans. Overall i'm impressed, and will have no qualms adding the KKTO soon to my stable of popper, coretto, and the FZ-RR700 Baby Roaster.

Upgraditis, here we go again  ;) Looking forward to joining the KKTO mob.

I forgot to mention another reason to get it was to roast for others.

I'm the only coffee drinker in the house, so the Baby Roaster does fine in that regards, but since i've got people wanting beans from me on a regular basis, now i want to give them something better in the cup than the coretto.

No matter what i do, shorter roast times, longer roast times, DMM logging all the way, uncovered, covered, insulated etc i find the taste quite acidic. As an espresso, it is brighter and acidic compared to the Baby Roaster.
As a milk coffee, this acidity does put it in it's favour a bit, especially if sugar is added.

I just want something that's affordable, can roast a 500 - 700gm batches and is a drum roasting principle.
That's where the KKTO fits the bill for me.

This waiting is going to kill me a bit, but i'll have to be patient til christmas, so in the meantime, i'll be saving up all the tips from the restaurant customers.

Then after the KKTO, maybe i'll go for the Breville  ;)

The batch size of the KK and the taste were the big draw cards for me... that and I had all of the bits around the house.  You won't know yourself Gary come Christmas. But surely Perth is like Townsville... Don't ya just leave he beans in the sun to roast?  :rofl:

Hi there Brett.  Hee hee,

The north west part of this state can certainly guarantee divots and scorching of the beans together with cooking bacon n eggs on the rocks there.

Down here in Perth though, the weather has been acting strange. Broke the October record for wettest month and very mild temps.

Blaming it on the Queen who's bought in the British weather to CHOGM.

Getting towwy now. The coffee journey is a source of sweet pain.
I'm not one to steal, beg or borrow. Prefer to save up the old fashioned way.

The joy of looking forward to a new toy. . .   :tearhair:

Yesterday I roasted 500g of the Geisha from Bean Green, 1st crack at 11:30 and pulled at 15:30 before 2nd crack. I couldn't resist trying it today and am impressed already. Will try it again in a few days.
I also roasted some of the Colombian SW Decaf  for the wife today, another 500g batch in the KKTO and it looks awesome. 1st crack at 11:05 and I dumped when 2nd came at 15:50.  Think I'll be trying my first ever decaf...
Oh, both of the two above batches were with a halogen TO. I know I wasn't doing the 1kg like my first roast but it did seem easier to get up to temp and to control the heat between 1st and 2nd cracks with the halogen.
I love my KKTO!  ;D
