After the old forum software breaking in a way that we were unable to fix, we've migrated the site to a new platform.

Some elements aren't working as we'd hoped - some avatars didn't survive the transition, and we're still having issues with attachments that weren't added as inline images, but we're hoping to have that all sorted out soon.

    When I designed the central heat gun method ( I lost the drawing in a computer change ) I envisaged a Stailess Steel " turbo creating air deflector " just under the heat gun nozzil I will let out one small secret of the new KKTO design if it goes ahead - if not it will be published and be made available free to all If you search on the WWW for a Tornado Cyclone ( used in the car industry as an aftermarket accessory ) From memory it was invented by a Korean physicist and been around for couple of decades Attachment not found.

    Hey KK, which diameter cyclone did you think would work?

    The largest dia @ approx 60mm would suit the standard KKTO KK

    I have adapted my KKTO to take the HG2300E Steinel Heat Gun, its the straight type of heat gun and is rated for 2300W, 50-600deg C. It has sliders for incremental adjustment of fan and heat, i was going to use a Cyclone Vortex to distribute heat better, but initial trials show it to be so far superior to Turbo Ovens as is that I probably wont bother. First iteration is a fair hack of a job on an old TO, but it works and proved the viability of the option. Materials required beside the $400 heat gun were a bit of AlFoil, some high temp silicone, a coat hanger and a bit of hose! [attachimg=1] [attachimg=2]

    The setup is amazingly controllable with the sliders, easy to replicate my TO profiles and i reckon it would roast 1KG easy, the sliders make it a dream to adjust on the fly, [attachimg=1] It looks to me like the nozzle of the Steinel has some sort of vortex doover anyway, [attachimg=2]

    The first batch looked OK, (apologies for the out of focus image!) [attachimg=1] [attachimg=2]

    You will definitely do 1 KG It's been achieved several times repeatedly on bcspark's unit when we both got together on a few occasions It's also the same hexagon model unit I had in mind KK
