    My build has deviated to the point where a new thread would be of benefit. Pics included.

    My reflow oven is a Sunbeam BT2600 just as Bleckers’ in the linked thread, with the exception that I will;
    1. Replace the metal resistive elements with Quartz ones from Uxcell in China. Via eBay reseller https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com.au/ulk/itm/391574144754
    2. Add a doubler plate to the rear oven wall from inside, reducing radiated heat emanating from the rear of the oven. I’ll use the crumb draw cut to fit.
    3. Elements will be wired up to individual SSRs. https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com.au/ulk/itm/292295530690
    4. Using different elements requires modifications to accomodate different diameter and cable connections for the new elements.
    5. I had to go pretty far with disassembly so I could remove the original elements and preserve the shrouds that covered them.

    In regard to your question about the front panel - my front panel update was simply a flat piece of aluminium that i shaped to match the curve of the existing factory panel, then screwed it over the top using 4 x M3 countersunk screws. The overlay panel has the cutout for the switch. The original panel is still underneath, and I cut away what I needed to clear the switch. Does that make sense?

    Have finished my controleo3 build (pics at https://photos.app.goo.gl/JcNxEKVBhTXyzHyJA so I don't fill up your thread)

    The resistive elements really let it down in trying to keep to an ideal ramp profile - the power and insulation are amazing though! I'm tempted to pull it apart and replace it with the uxcell quartz elements - does 28.5cm seem like the right length Mudgel - like https://www.amazon.com.au/uxcell-In...541326795&sr=1-2&keywords=quartz+element+28.5

    That said, it really does the job fine with a tiny bit of profile tweaking, maybe not worth the hassle, especially after lining the whole thing with ceramic fibre blanket, that stuff is pretty painful to work with.

    28.5 is a little short but the next size up (31cm) is rar too long.
    I did some heating tests which convinced me to replace the resistive elements. They struggle to get upto temp, maintain it stable and cool down far too slow.

    I’ve been sick so haven’t been able to add some finishing touches.
