Suggest Me a Roaster!!

I second the DIY KKTO!

Assembling bits and pieces is no problem, just getting them is! ;D I don't have a huge amount of tools at home, just a few mechanical basics (drill, screwdrivers, spanners etc) so I may have to invest in some new stuff if I go down the DIY route. Electrical stuff I have almost no idea theory-wise, but if I get clear instructions I can do most stuff without a problem (although my soldering is a bit heavy handed...).

My first roaster is still operational and all I used was a drill, hack saw, file, tin snips, screw drivers Instructions have been available on google docks for years - https://docs.google.com/presentation/d/1H0RshF6QP8hNSBEbTTjDKLvAumuW5nHt5KfvU9i2Xqs/embed?slide=id.i0 Also have a look at this Hybrid KKTO build http://www.bestcafes.com.au/forum/roasters-different-roasting-equipment/kkto-hybrid/msg27367/#msg27367 KK

Cheers KK, I'll have a better read through it when I get home from work. I hadn't seen that one before.

The hardest bit is the agitation and shaft. Getting a windscreen wiper motor is as easy as ebay but getting a 5amp transformer to run it means Jcar or PC power surgery... J. Then the shaft and agitator is a bit of diddly fun!

I have motors and the drive shaft that fits the square drive, also other parts in the KK shop to make that easier KK

Brilliant! That was my one stumbling block Ash and it didn't matter because I already had a Behmor that was and is working perfectly well. My KKTO was a work in progress that took months of tinker/back on the shelf fun. If I needed one faster I'd be snapping these parts up while KK still has them.

Well its looking like KKTO build time :thumb:

Patience Brett 😃 I'm still fleshing out the idea at the moment! :rofl: And when I do get the ball rolling there will pics :coffee2:

you could always bin the control circuitry on the hottop and pimp it up with an arduino. Cheap solution and far better control options. Still have the roast capacity issues though. for 750g a week, I'd want something bigger than a hottop plenty tips on homeroasters.org to give you help edit: If your hottop is likely to end up dead, let me know. I might be able to breathe life into it and pass on to somebody else - wouldn't be anytime soon though.

Cheers UNM, thats something I hadn't thought about for a while. I did look into that lightly about a year ago I think. I'm going to build my self a KKTO, so once thats finished I'll revisit the Arduino mod for the Hottop. As an aside, I found what was wrong with my roaster last night. The chaff tray micro switch had a wire swinging free. This caused the roaster to automatically going into the 30 sec cool down mode, and may have caused it to do the auto eject thing as the beans were nearing first crack. Recrimped and soldered the offending wire so it should be good for another year now!
