MEW 267 – workshop tempering oven

[Mike CrossfieldParticipant @mikecrossfield92481]

Has anyone out there built the oven described in MEW 267?

I have just completed my version, which uses the same basic components and materials described in the article, and I’m concerned about the temperature reached on the exterior of the case (made from a stainless steel pedal bin).

With the oven set to 300 C the top of the case where the heater mounting bracket is attached reaches nearly 150 C, and the oven door is too hot to touch comfortably. With the oven at 600 C, the highest temperature I’ve risked, the temperature measured on one of the heater bracket screws is 300C!

I’d be very interested in anyone else’s experience.

External temperature issue

Hi Mike, if you want to send me an email, I can pass it on to Chris Gabel for comment.

The insulation is there to allow the inside to heat up, rather than keeping the outside to 'touchable' temperatures.

Thanks Neil. I have sent you a pm.
