![]() You must cover any open seams, hinges gaps etc. Now comes the tough part - applying the foil tape to the insides of the oven chamber including the glass door. Next, you'll need to use the silicone gel to seal off any areas that are open and where heat might escape from. Now, you'll need to disconnect all the wiring and remove the temperature controller and timer. Initially I connected all four heaters individually but they heated up really fast (like within seconds). Since I'm using 220V AC, this meant each element is rated for 110V AC. This usually means they are rated for half your AC mains supply voltage. I had two pairs of them with one pair for the top and another for the bottom. A quick note on the heating elements wiring: Usually you'll either have two elements or two pairs of elements. Open up the oven and you'll see the wiring. A great example is the Arctic Silver or the Noctua NT-H1. I used the ones that are used in attaching desktop CPUs to their heatsinks. Thermal transfer compound - for attaching the relays to the aluminum plate which acts as a heatsink for the SSRs.A small aluminum plate - about 12 in x 12 in - this acts as a the support structure for the SSRs as well as their heatsink.I also used a larger 5mm one to encase the connections for the neutral wire of the AC mains. Heatshrink tubes that would fit the 1 sq.Fiberglass sleeves - for the wires inside the oven.The ControLeo2 build guide uses reflect-a-gold which unfortunately was not available in my part of the world. Aluminum foil tape - to be applied inside the oven such that the heat reflects well and also for covering spots from where heat could leak and affect the heating of the chamber.A caulking gun - for applying the silicone gel.I chose the white one cause its easier to see where you are applying it and more importantly if there are any gaps. Silicone gel sealant - These are very commonly available.Fiberglass wool - for insulating the oven so that heat remains inside the chamber.Fork terminals and straight lugs - about 20 odd.I had 4 different colors lying around the house which was very convenient. mm electrical wire - about 3m in length if you go for a single color. M3x10mm screws, nuts and washers - about 10-12 of them.Mine has just a temperature knob along with a timer.Īpart from the oven, here is a basic parts list (does not include the electronics which is listed in the next section): Look for a simple oven without fancy controls and such stuff. ![]() These are essentially two pairs in series. Mine has two on the top and two on the bottom. ![]() 1200W to 1500W preferably with 4 heater elements. They heat and cool rapidly and are cost effective.
