Following my successful destruction of my solid oak door (burnt it overnight), I have been given a sink cutout from an Oak worktop. The problem is that it is made up from Oak blocks that have finger interlaced joints and have been glued together. (hope that makes sense) I will put a Thermolite block on the inside face and fire rope around the rebate. Has anybody tried this type of material? will the heat cause the glue to fail? Bottom line is it has two chances.

G'day Phil Had one of these doors for years. First one was bolted together. Cracks from the bolts expanding didn't stop them from working. Next one I silastic on. The silastic was well protected by the insulation. You probably will not need the rope for a seal as the block can be cut to shape with saws and rasps for a tight fit to the entrance. Regards dave

G'day The oak will no worries. A suggestion to make that thermometer last. Remove the nut that holds it too the door. Fit the door to the oven then fit the thermometer. Remove the thermometer and put it saftley aside then remove the door. No chance of breaking the prob off then. Finally stow the thermometer away inside out of the wheather I wouldn't leave my peal outside and the thermometers a lot more delicate. Regards dave

looking good, i think that door will serve you well. when i close mine up after a full Saturday night firing it's still 250 to 300 degrees in the morning. heavy but holds the heat very well!

First real use of my oven over the Easter Holiday. Pizza dinner one evening, oven still hot enough to slow cook pork joint next day.
Two problem
1 Hairline cracks have appeared in the K Rend, exterior still cool. Do I fill them and paint with external masonry paint? Am I being too fussy?
2 Now on my third door, Using thermolite as insulation with 25mm (1") timber facia. severe warping and cracking means I will have to consider another door. See picture of door above.
Any ideas?
Phil

I think the cracks will reopen with each high temperature firing. My K -Rend did the same, but I wasn't worried as I put a roof over mine. You almost want something very flexible and waterproof to cover over the hairline cracks. I guess the risk otherwise might be water getting into the cracks and then freezing and expanding, and gradually breaking down the render.

See picture of door above. Any ideas? Phil 1. Yes, that's what i do. I usually fill any cracks and repaint annually. 2. I also have a timber facia and an insulating panel and have had the same problem. If you only place the door on when the oven is under 300 C there are no problems. Apart from pizzas there's not much that needs baking or roasting north of 300 C anyway. For shorter periods (half hour or so) the door can be placed or half placed, at the higher temperatures. Timber has a tendency to cook and burn over 250 C. The insulation is enough to do its job to prevent this so long as you don't exceed 300 C. I also reduce the conductivity to the wood by using as thin as i dare ss bolts and separating the insulating panel a couple of mm with some high temp silicon.

Hi guys, haven't posted in a while, My DIY build has been a 100% success, in fact too successful at times where it is so well insulated that it takes ages from Pizza temp 400º + to drop to 180º to cook a roast. Still Practice makes perfect. The problem I have got as you can see is Algae on the K Rend finish, This side of the oven does not get a lot of sunshine. Can anybody help with advice on removing the algae (I have tried bleach and a weak solution of brick acid). Once removed anybody had experience with painting KRend? Thanks Phil
