Hi there! I’ve been working on the weekends to make progress on my oven and I have finally gotten to the part where I will put the foam form up and start building that… however I just realized I may have made a huge mistake.
As you can see in the picture I have modified the cooktop to have a hole lined with firebricks to allow for a propane burner (sourced from Ward burner systems) so that I can use it without wood potentially or just to light wood… anyway that is all to say that I had a little more complication as it relates to cutting the firebricks for that area and ended up having some cuts I’m not all that proud of. Also, since the surface ended up being a little higher than the full length of those bricks I ended up needing to grind down the cooktop bricks around the hole to slope down and hopefully have a smooth-ish surface.
Ok that explains the weird thing I did, but here are my questions…
- The red bricks around the top… I only now just realized that I was supposed to use fire mortar around the perimeter. I read the instructions 100 times but somehow missed that until now. I guess I just associated those bricks as not getting hot so I didn’t logically tie that step in properly. Sooooo… Do I need to tear this out and redo this? I hope not, but there will never be a better time to do it.
- The perfect flatness… It’s far from perfect but the peel moves ok across the top and I wondered if using my concrete polisher to get the top more perfectly flat would be a good idea. Again, there will never be a better time than now, but do you think that’s going too far?
- Filling the cracks with firebrick dust. I have dust leftover from polishing out the height differential of the “hole bricks” to the cooktop and if I do item #2 above I will have more dust. Is it a bad idea to try to fill my gaps with firebrick dust? Or will it be problematic for my food?
I think that’s it. I normally consider myself pretty handy but masonry work has proven that I have a very long way to go!
