peveleth, It is better if you start a post in the forum with your question. These shouts go away in time.

For Gene Cafe Roasters I have an older Gene Cafe Roaster. Temp fluctuates probably showing age. Question: For recent owners of the newer Gene Cafe Roaster, your opinions?

Morning Ed, I haven't done any green coffee hoarding yet but am hoping the supplies don't end up like the toilet paper isles!

Jeremy's KKTO Build, Parts
jkruer01
Hey Everyone,

I have decided to build a KKTO. I am trying to assemble the required parts and would like your input/advice.

I found a "Flavor Wave Turbo Convection Oven Model AX767MH Replacement Lid Power Head" on Ebay for $25:
http://www.ebay.com/itm/Flavor-Wave-T...SwUdlWecN5

I think it is Halogen and 1300W. Will this work good? Is there a better recommendation?

I found this 8qt pasta cooker on Amazon for $35.
http://www.amazon.com/Stainless-Pasta...sta+boiler

Will this work good or is there a better suggestion?

What about for the motors? Is there a good place I could buy the motors online? I saw one thread talk about the Monster Guts Power Pack (http://www.monsterguts.com/store/prod...ctid=17761) but at $72 it seems kind of expensive to me.

I have seen this link posted several times for silicon tubing:
http://www.usplastic.com/catalog/item...;catid=799

What about Thermocouples? I want to get the kind with the metal nipples like is shown in these photos:
http://imgur.com/a/qUCN7#0

Any recommendations?

Thanks!

I was trying to think of what could be used to insulate the outside of the KKTO pot. I started thinking about the spray foam insulation that you can buy from HomeDepot.
http://www.homedepot.com/p/GREAT-STUF.../202023037

This is for "Fire Block" so I would think the heat wouldn't be a problem.
Would you be able to spray and cover the outside of the pot?
Would it stick to the pot or would it fall off?
Is it safe to be used around food items (coffee beans)?

Thanks!

Assuming I buy a wiper or window motor, how do I wire the motor up to some sort of power supply that I can plug in? Are there instructions somewhere on how to do this?

What parts do I need?

Thanks!

Hi,

Have you taken the time to go through the other builds of this same type of roaster? They are full of all the stuff you need as well as modifications others have made.

See Kosmo's and Jacks...

I have read through all of the other threads. These are the questions that I have remaining after reading all of the other threads.

The problem that I have is that many of the links in the other threads are no longer active. So there are many times where someone will say, Instructions are here ... but the link no longer works.

Thanks!
 
ginny
hmmmm, links should still be there as no one can come and take them. perhaps in another post in that particular thread. stuff does get lost when you have posts all over the place.


you can PM the author of any thread/post and you may get a response but many simply get what they need here and never come back; that's the way fourms can be.

They are links to 3rd party sites that are no longer valid. For example, here:
http://forum.homeroasters.org/forum/v...owstart=20

On post #32 there is a link to a Google Doc, with instructions on how to build the KKTO, but when I click the link, I get a "This webpage is not available" message.

There was another example somewhere that showed how to wire up the motor but when I went to that 3rd party link it didn't work either.

There was another post somewhere to a thread on CoffeeSnobs but that thread no longer exists either.

This is just the nature of the web....not much you can do about it.

That is why I posted my thread. I read all the others and I still have questions about how to build it.

Now to your questions

A motor will turn both ways ( clockwise and anticlockwise ) depending on how the wires are connected only 2 wires
Use a window winding motor as they are simpler and smaller

I connect it anticlockwise
They run on 12 volts so you will require a wall wart power supply of min 2.5 amps to 5 amps X 12 Volts

Re - Spray foam - NO it won't work
You can double line the outer pot with an air gap or use muffler tape and a fire blanket

Turbo ovens
I always recommend a 1400 watt model - others will work but will roast smaller batches

Silicone hose - I use High temp vacuum hose that is used in racing cars and it's easy to find and obtain

Pot Set - That Amazon pot set in the link should work

That link works for me. Google docs has a list of supported browsers and operating systems. I have attached a screenshot. They also recommend clearing browser cache.

Koffee Kosmo, the KKTO designer is usually here each day and is very helpful.

Your turbo oven should be OK, we have many people using the newer halogen types.

The pasta set looks good too. Have KK verify this to be sure.

The link to the motor is an automotive windshield wiper motor. Others have used a motor for automotive electric windows too.

The silicon tubing is one of my links (I think) and that is what I use for the gasket between the pot and the turbo oven top.

The shaft that couples the motor to the stirrer was the biggest problem for me. I used a long extension from a 1/4 socket set, then purchased one of Koffee Kosmo's KKTO shaft assemblies.

Also for your DIY skills
I recommend the Ver 1 KKTO build like Jack H has built

It's easier and more forgiving to ones skill set

The link is working for me now. Before I was on my work network and now I am on my home network. I bet my work has Google Docs blocked.

Thanks!

Thanks for the great info, I appreciate it.

As for the power supply, I have no idea where to even start. What kind of device would have a power supply like that? A cell phone charger? What are some commonly used devices?

For the 1400W ovens, what common brands are available that are 1400W? Most of the ones I have seen are only 1200W.

Thanks for your help!

Thanks! From what I have read the kits are no longer sold. What have others done since the shafts are no longer available? I looked for window motors on Amazon and noticed that all of the ones I saw don't have a square motor shaft, it is more star shaped. A socket shaft wouldn't work for these would it?

Thanks!

I think ver 1 is what I am trying to build, correct me if I am wrong.

1)Get a pasta cooker and drill a whole through the bottom of both pots.
2)Wire up a window motor (still not exactly sure how our to what)
3)Create a shaft that attached to the motor and thread it through the holes (still not sure what to use for this )
4)Use whisk wires as arms and attach them to the shaft to stir the beans
5)Put the turbo oven on top
6)Add insulation

Is this Ver 1?
 
Koffee Kosmo
V 1 uses a single pot with a suspended insert inside it
V 2 uses the 2 pot pasta set

V1 is same as Jack H's avatar

So would this power supply work for a window motor? I'm guessing I would cut the end off and connect the exposed wires to the window motor? Is that right?

That is normally how you would connect the power. You need to get a power supply that matches the voltage and current specifications of the motor. Normally 12V but the current can vary depending on the model motor you get.

The nice thing about the wiper motor is that you can also wire them to get different speeds. Also, the motor shaft connection can be easier. The window motors are usually belt driven and often have a pulley attached to the shaft.

Thanks! I will look into those. Looking online it looks like most of them have a square shaft which would be easier to attach to.

Thanks!
