Hey Scotty even though I'm not an expert or anything I think you've done a great job! And really professional too.

Great job on keeping the finish so perfect! It is hard enough to work with metal, let alone not marring the finish!
Since you are enjoying summer weather there, the least you can do is send up a pizza or two!
I might try a pizza party next weekend if it doesn't snow... or maybe even if it does!

Hey John,
The finish on the facia is "brushed" stainless, that's how it was supplied, the door was also brushed, but after the welding it needed a bit of polishing to shine it up a bit. Will be interesting to see how it holds up to the cooking smoke, I'm hoping it will just wipe off with a damp cloth? We will see this weekend.

Great Job Scotty!
Wow that stainless really pops! How did you get that finish on it? Polished, sanded, sand blast? However it was done, it came out perfectly. Now enjoy the fruits of your labor!

And today I finished it. Next photos will be of the fire ceremony....



I did make a small mod to the door, added a handle so that I don't end up dropping it on my nice smooth sandstone.

Gudday Scotty
Congrats on the oven !!! very smart looking oven. Love the stainless on the entrance.....Ovens are a lot like people who fall asleep on buses and trains they all dribble...Trouble with ovens is the smoke dribble is hard to wipe off....recon you have it beat!
Great looking door... don't worry about the weight (mines 12 kg) once you have the door on and slow cooking your best to just let it cook long and slow and not peek ever few mins

Regards Dave

Re: Scotty's 36" Build on the Sunshine Coast, Australia.

I ended up choosing Dark Charcoal for the colour.

The door, its a little over engineered Weighs in at about 15 KG..... whoops. Oh well workout time.

Door in the hole.

Doug if you look at the perspective picture you will see a nice big stainless fridge, that is my beer and wine fridge!!

Render is always sharp washed sand with no clay otherwise the clay content will shrink and crack.

Re: Scotty's 36" Build on the Sunshine Coast, Australia.

I have a door being welded up today. its 6mm stainless on the fire side with 2 inches of calcium silicate sandwiched in the middle and 3mm stainless on the visible side.
Yes it is a bit heavy!! but will give me a good bicep workout when I use it.


And a perspective shot of where the oven is.

Re: Scotty's 36" Build on the Sunshine Coast, Australia.

Ok so I have pressed on with the build this week. Have reduced the qty of Fire Clay in the mix to see if that reduces the cracking, and it seems to have worked. I have 3 layers of render on there now each with less FC and each showing less cracks. But yet to fire it up for a big burn yet. Its only had a couple of small burns and the original 30 odd hours of gas burner heat.
Here is the sandstone that Im intending to do the bench with.

I have a nice laser cut stainless facia on the front

I was thinking of going for Blue as the dome colour, but after seeing it I have changed my mind, will now try a dark charcoal.

Re: Scotty's 36" Build on the Sunshine Coast, Australia.

Slump cracks can be avoided by the following

Render layers should be applied to about 1/2" thick.
No clay in the mix.
Make the mix thick (not too much water)
Wet the substrate before applying the render.Skip this point because there would be no point wetting the blanket.
Use sharp sand not grains that are rounded. I use silica sand.
Add fibres to the mix.

I use 4:1:1 silica sand, lime, cement.This is a well tested and recommended recipe.
You should not do the work if it is exposed to sun or wind if possible.
I also wrap the whole thing in cling wrap, for one week, to hold in moisture while it dries and to increase strength.

Hi Scotty,
Great looking job so far!
This might be what you're describing regarding the door design. All mild steel and works great!

Cheers,
Russell.

Re: Scotty's 36" Build on the Sunshine Coast, Australia.

Came home tonight after about 9 hours since I did the above rendering and there are some substantial cracks in the render and it feels a bit loose or it seems to float on the blanket still. It is still a bit wet so I know its still setting, but will the cracking eventually stop on the render? I assume I have to do a few coats of this stuff, how thick should it go??
Cheers
Scotty

It looks like there is too much clay in the sand, you need washed sand for render, its the clay shrinking that causes the cracks.
