Not sure of your minds eye
Do a drawing so I can see where you are going with this

I doubt a drawing would help in this case (especially given my drawing skills).Will try to explain differently.

Goal - avoid the need for reducer ring.

As delivered, TO has:
a glass pot (not needed)
A TO unit consisting of electrical bits and glass pot lid with nice big hole in the middle. The actual electrical heart of the unit is fully enclosed and mounted to the glass portion by screws, mounting plate and gasket.


Why not swap the large glass lid for a smaller metal one that is designed to fit the roasting chamber selected?

How will you address
1) Volume parameters in the roast chamber that need to be strictly adhered to
2) Insulation needs to be added to reduce heat loss
3) Perforated Insert needs to be manufactured
4) Drive & motor system for a agitation

Its a simple design bit it needs to be put together right

Just for the sake of this thought exercise, suppose I had all parts of a standard TO kit and made this one change.

Any reason not to?

If its this one change - then the adapter ring will do that job
It will fit on pots from 24 cm to 31 cm

Point is, the adapter ring seems unnecessary to me (and I don't like the aesthetics).

So why is it there in the first place (Apart from allowing non DIY types to put everything together easily.)? Does it fulfill any other function

I designed it to have 3 functions - It also holds on to the TO and because of this it becomes one unit

Now to the functions
1) It can be used to marry a variety of diameter pots & if necessary it can be used inverted (both ways)
2) It can be used to facilitate other types of heat sources or dual heat
To further explain - 
It can be used in conjunction with a round electric fry pan with single or dual heat sources
3) It is a safety devise to rest the TO in a safe cradle

I've been meaning to ask KK - are you still having trouble sourcing pot sets? KMart recently had the right type in their home brand - not sure about the right size tho. Fairly cheap too - about $30 from memory.

Yes we are still having issues with suitable pot sets
Thanks I will look into it
Edit - have found nothing on the K Mart AU site

Sorry guys, Tapatalk doesn't actually store the photos you take on the phone. No pics.

Suffice to say it looks like a normal potset, 24cm has both the pasta insert and the colander and bakelite handles.

How about this KK

Not sure if it's the same as what Kelsey found but this one has silicon rubber handles.

Not sure if i should have started a new topic of stay on this one. Am sure the mods can shift if they see fit.

Just want to know if anyone has cut slits in the roasting chamber of the KKTO for better chaff extraction.
I know that it has been done before but i could not find it here or the other forums.

If it's possible, what is the best tool for the job?

I feel this is going to be quite a challenge because my tools are very basic. Hoping the right tool can be found at places like Kennards Hire.

I have cut slits ( done as an experiment )
Some have larger holes along the top (** but only under the handles ** ) for reasons of pouring out the roasted beans

It helps with the chaff of dry natural processed beans that have a tendency to shed more chaff than normal

The best tool is a Dremel

Thanks KK.

Will see if i can borrow , beg , steal or even hire a dremel.

Another question, how do you clean the stainless steel roasting chamber? and how often do you do it?

Mine has accumulated dark stuff from all that roasting.

I have no problems cleaning the glass of the oven, but the stains from the chamber seems very stubborn.

I did mine with an angle grinder then smoothed any dags with some wet and dry 320grit.  worked well also.

Me too.  I just joined 3 holes at the top under the handles on both sides.  So I only have 2 slits.  I bent them slightly too so that one side pokes out slight to catch the chaff (just note the direction the chaff spins in), and the other in, so make the hole slightly bigger.  Only a little bit of chaff gets left over on really chaffy beans, most if not all ends up down below as intended.

Note, be careful if you use a grinder, they are quick, and one slip and your pot will be fruited.  take it slow and steady.

I've never cleaned my pots, but I've had to clean my TO glass a few times.  It just came off with some soapy water and a non-scratch scourer.  I get the blue ones without the sponge for my washing up duties. :)

I clean my KKTO glass with a mild scourer and espresso cleaner. Doesn;t seem to scratch. Nice to see the beans as clear as daylight though clean glass rather than murky and dirty.

If i can't hire a dremel, then i'll go for angle grinder.

Another question, i tried drilling through the side of the roaster to install a thermocouple but gave up due to the strong metal in the past. The thing wants to slip n slide everywhere.
Any ideas?

A square of masking tape over where you want the hole will steady a sharp quality bit to bite.  Don't run he blade at ill speed or you quickly take the temper out of the metal.  :thumb:

Just as Brett has said above
Put some masking tape on the area as this will stop the drill from walking/slipping away
If at all possible punch a small starter indentation
Use a sharp drill bit
Use a slow speed if you have a variable speed drill

Doesn't need to be a Dremel. I have a cheap dremel lookalike Ozito from bunnings.

I cut vertical slits in mine by joining holes from two rows together. A very easy job with a Dremel cutting wheel.

I have one of those also and it would do the job.  $40 is the bargain price they go for but you may need to purchase some spare carbide cutting discs because the stainless will weare them quite quickly.
