[volt-nuts] Oven thermal insulation

[Dallas Smith]

Hi Randy,

 

I used a box in a box then shot yellow window or gap fill insulation from your hardware store, use minimal expanding type. Fill around the spaces between the boxes with the tube but very slowly. You will get this on your hands so use your gloves because you will have to hold the boxes in place as it expands. After it dries cut the top off with a bread knife. May take a couple of tries to get what you want.
