Re: Pizza Bob's 42" Build
It is easier to level out a larger area rather than a single brick gap. When the damaged brick is removed, take out a few around it, trowel out a sand/fireclay mix and reinstall.
If that doesn't appeal to you, you have two options. Get the setting bed perfect or create a space for material to go under compression...because the floor is tight there is nowhere for the material to go, except to squeeze into the joint, which will lift the brick or prevent it from being leveled.
To create a space, you can 'frog' the brick....cut or grind a hollow in the center of the brick, which will allow you to tap or push the brick into your setting bed without forcing material into the joint. Just before you set the replacement brick, rake the setting material away from the surrounding floor brick ( like a bevel)...this will further prevent it from squeezing up, and direct it into the frog.

My thought is you still will have your non-hardening mix underneath the bricks so a little refractory mortar will become part of the replacement brick. A wet mix will crack easily and relieve any tension but will be hard enough to keep the brick in place and wet enough to squeeze between bricks as you tap it down. Maybe keep pressure on neighboring bricks when setting the new one.

I only have my own oven to go on. I'm finding it hard to get a table knife blade in the gapes of the hearth tile. That why I suggested a thin wire . I would think it hard for any mortar to be able to squish up in that gape. Perhaps it depends on the size of the gape. I'm certain it wouldn't work on my hearth

I must have dropped a larger size log on the hearth floor and chipped one of my bricks. Luckily it's towards the front of the oven but not in the vent transition area. I would like to hear how others replaced hearth bricks and what issues/challenges they had to over come. My concern is not getting t he new brick level with the rest.
Any thoughts?
Hope everyone is doing well!

There is no one that I've seen that has had to do this and posted there results. So I'd would be great if you did make a thread in the tools/tips section as it would be a welcome resource.
I have replaced path pavers before and its a sod of a job there hard to get out with the packing sand and hard to get back in.
For what it's worth this I'd how I would go about it.
I would try and remove as much of the ash from around the brick as was possible. I've just tried a piece of thin wire and a shop vacuum on my own oven. Seems to work but its time consuming and laborious.
Then you could put some dyna bolts into the brick so you would have some purchase to lever it out. You could consider drilling a series holes so you could break the brick into sections , that could work.
Getting it back in will be fun. Hopefully you have one of your original batch of brick that would be good. One thing going in your flavor is that firebricks are pretty uniform. I would replace it straight away least the other around it move. I would also consider chamfering the bottom edges so its less likely to catch on the way in. Getting it level I would think too high would be best, then you have the option of grinding it down should you need.
Hope something here might help
Regards dave

Re: Pizza Bob's 42" Build
Hey Bob,
I haven't been on FornoBravo in awhile either. Your oven looks great. We fire up ours now and then but not as much as we used to. Still love it though. Glad to hear you bounced back after the surgery.
I would go heavy on wet mortar and just tap in the new brick until flush, then sponge up the excess.

Sorry for the delayed reply.
I wish I had the skills to make the dome lower! The oven floor gets so HOT which cooks the bottom of the pizza quicker than the toppings. I haven't tried bread in there but I'm sure the slightly higher dome would be better for this. As for the pizzas, I "dome" the pizza before pulling it out of the oven...basically hold the pizza close to the dome and it acts like a broiler - a really HOT broiler. The toppings get a little carmelized and life is good!

I finally, finally, finally put the keystone in today!!! It was much easier than I thought it would be. I didn't require any forms for this. The HeatStop 50 works so well - I haven't used any forms since the last time I used the indispensible tool on the fourth row. The bricks just always held in place right up to the keystone.
The keystone ended-up being two pieces stacked on top of each other. I traced the opening of the dome onto a piece of paper and then transferred that to a brick to cut the keystone(s). My wonderful 13 week pregnant wife came out and lightly tapped the keystone into place as I laid on my back in the dome watching the keystone come to the correct depth. The sides of the keystones were all tapered so it felt as if it tightned everything up nicely. I think I added a little too much mortar between the upper keystone and lower keystone because it didn't seat as low as it did when they were dry. So, as you can see in the pictures, the upper keystone is slightly proud of the dome. No big deal because this will be completely covered soon!
You can also see in one of the pictures I made an "okay" sign with my fingers as a shadow - because everything is okay now that this dome is DONE!
It sure feels good to have that keystone in there!

Be safe!

Are you using it for the oven? It does fit nicely there for sure.
Be careful and safe also

Re: Pizza Bob's 42" Build
Hi Bob,
First thanks for the insulation, like you said you can never over insulate! Secondly and more importantly, Your oven piazza is just spectacular, bellisimo, fantastic, looks great in the pics, but looks ten times better in person! Patio set is such a perfect fit/compliment and overall party perfect! The green granite counters make me green with envy! And of course the oven inside and out is perfection! Job more than well done!
Wow!

Bob,
You not only set the bar high with your oven build, but for me it is out of sight! Great video documenting it all!
