Eth Nat Yirg Idido roasted yesterday. I dropped some off at a friends coffee shop. In a few days he will brew it and tell me what he thinks. We believe my roasts are better than what we buy.

Jeremy's KKTO Build, Parts
JackH
The square shafts can fit a socket and then an extension. I was using a socket the same size as the motor shaft which connects to a long extension.

The square pieces of metal are key stock available in different sizes and lengths. Rather than cut the socket extension to length (which is very difficult), I used the key stock and cut it to length.

Just wanted to throw this out to you, I picked up a Minion Prop Power Pack for my build. All the necessary parts for the motor and power supply for 48 bucks plus shipping. Brand new wiper motor made for continuous use, and the correct power supply. Just an option if you don't want to piece it out.

$48 is much more reasonable. I looked at another one of their kids but it was like $80+.

I can't tell from the pictures, what kind of what does the motor have? What did you use to attach the agitator shaft?

Thanks!

May I suggest to get an old 12V laptop computer power supply
Just about every man and his dog has one of those laying around

The motor will accept a star socket where you can either use a socket extension or square stock. I haven't completed mine yet because of being busy and the holidays. But it looks like it will be real easy.

The motor is brand new, and if bought alone would be 24 bucks. It uses blade type connectors, and the wiring only needs two going to the motor. They make the wiring very simple, so it takes the hassle out of it. I tried getting a motor local but the core charges are 20 bucks alone for new, and I was admittedly too lazy to hit the salvage yard.

KK is absolutely right, the power supply is just a 12V laptop computer power supply. I used to have them laying around everywhere, but had cleaned out a lot of things, and gave them away, So I had to buy one. Then I just just needed a 2.1 x 5.5mm female jack to wire it. So that was my reason for buy the kit. But it is easy to piece together if you have the parts.

Does it matter what type of metal the key stock is made out of? I'm assuming some metals are not food safe at high temperatures.

Just use alloy
It's economical to purchase and it's easy to work / fashion into the shape you need with a file

So here is an update so far:

I bought a used Galloping Gourmet Turbo Oven from Ebay. You have to be careful, because some are listed as only 1200W. I made sure to buy one that is 1470W.

My mom had a used double pasta pot/strainer that she gave me for free.

I bought the Monster Guts Minion Proper Power Pack http://www.monste...amp;page=1. It has a threaded motor shaft with a nut that screws onto it.

I bought a socket that fits over the nut from Lowes.

I bought silicon tubing from Amazon: http://www.amazon...ge_o04_s00

I bought 1/4" x 1/4" key stock from McMaster Car to fit inside the socket: http://www.mcmast...s/=10ungj6

I bought a welding blanket from Amazon for insulation: http://www.amazon...ge_o01_s00

I bought a thermocouple from Amazon: http://www.amazon...ge_o02_s00

Right now, I am waiting for all of the parts to be shipped.

Don't forget to factor in the recomended volume of the roast chamber for best results

The pots don't have a size listed in them. However the outer of is 9" in inside diameter and 7" tall (6.5" to the lip that the inner pot rests on).

The inner pot is 7" tall (5" to the lip that rests on the outer pot).

What is the recommended volume?
 
Koffee Kosmo
I work in the metric system so you will need to convert
Lower pot used is 240 mm inside wall diameter
The top pot stacks above the lower pot

Recomended volume is dependent on the batch size 7 to 9 litres
Lower volume for larger batches of 700 to 1 kg

That's why my double pot set was on the smaller side to make sure my TO was able to handle it easily.

9" = 228mm
7" = 177mm

If my math is correct the volume of the outside pot should be about 7.23 liters.

But you want to calculate the total combined roast chamber volume including the dome of the turbo oven

I roasted by first batch of beans. It didn't go exactly as I had planned, but it was at least acceptable.

I pre-heated the roaster until it was 315 degrees.

I dumped in 1lb of green coffee beans.

It reached first crack at 11:15.

I turned it off at 15 minutes when the beans reached 420 degrees.

Here is the results of the first batch. I haven't tasted them yet.
