Re: NW Ohio Build - Opinions welcome

Foamglass finally arrived!!! Crappy timing though because I just purchased a major distraction...

Re: NW Ohio Build - Opinions welcome

The economy of a diamond blade would be a winner I think. You will use a great many of the reinforced fibre discs in a build. The first expense is often the thrifty way out.

Hello

That makes more sense but you can get some incredible clearance deals at times.
Not used one of those blades/wheels on brick. How does it cut?

Re: NW Ohio Build - Opinions welcome

My last post may have been misleading...I didn't buy a diamond blade but one of these instead (see pic).

Hello

Great buy on the 10" blade. If they have more it may be worth picking up a second one just incase. Keep the receipt if you do not need it.

I have seen a post where someone rigged up a water supply to keep the blade wet while cutting.

Re: NW Ohio Build - Opinions welcome

Still waiting on the foamglass so I decided to cut the 45's for the arches. Was concerned about how to accomplish said task. I had purchased a grinder and a 4" concrete disk however that ended up being difficult if I wanted a smooth\perfect cut so I researched on youtube and there were a few examples of guys using regular saws to cut brick. I figured since I had to cut only 8 brick I could risk not using a wet saw. I found a 10" concrete blade at lowes for $5 and soaked the brick. Worked perfect just don't rush it and keep the brick wet (pat dry with towel).

Re: NW Ohio Build - Opinions welcome

All, In my original post I stated --I plan on installing 4" on foamglass on top of the 4" pad of concrete which sits on top of the lumber. I'm waiting for the foamglass to arrive and laid out the brick directly on top of the concrete so I can start cutting the brick in anticipation of finally assembly. So NO I am not setting the firebrick directly on top of the concrete pad.

I understand if you missed that --I do it all the time skimming posts.

gugahulk - I used wood for both reasons (easier to build and aesthetics) but mostly for the aesthetics.

Re: NW Ohio Build - Opinions welcome

...............There are several posts where people are concerned that they didn't get the correct type of sand (silica), and then there's the issue with lime--lowes and home deput both sell it in the garden section but there's an additive of soluble calcium. Not sure if that will mess things up but I get concerned when it's not just straight lime. So a little more work on my end finding the exact match for everything but if it's already correctly mixed and contained in the glass block mortar mix my life is easier. -A

Perrysburg,

I did a very quick search for your area. I think, that these folks are fairly close to you.

Check out their miscellaneous products section.

They list masons lime, fireclay, and silica sand. You may have already checked them out. If not, a phone call might help you do some one stop shopping .

Re: NW Ohio Build - Opinions welcome

After I saw david s's post I was like ok. You should be ok as I was thinking you were going to put some time of insulation under the floor firebricks. So, i thought you should be ok as the insulation will protect the concrete and wood under it. But than I realised that you are using ZERO insulation under the firebricks floor. Wow, thats crazy. I am not an expert but that is scrary NO? Remember your oven will get 1000 F in there and that my friend is SUPER HOT. Over time even that treated wood will get drier and drier. I would always be worried. I did the same thing on my Brasilian BBQ you can see on my build. and I wish I didnt but I put 12 inches of concrete on top of that 2x4 treated wood. and on top of that I added 2 inches of insulation board and I am still worried. I build it to last me for ever. So, I tried to do it right and later found out that it was a mistake but its to late to correct it. But I hope you are ok my friend. I must say the base looks nice!

I have a question for you. I am building the same type of oven you are. Why did you choose wood for the base? Did you like the look? Was it easier to do than concrete? Why was it the final choice?

Re: NW Ohio Build - Opinions welcome

gugahulk -- I was on the fence when initially designing however, I saw a post where someone had done a similar build using wood and they did not have any heat issues. As a precaution though I did leave 2 gaps so that I can monitor (infrared thermometer) the base of the cement pad from below on the initial burns.

deejayoh -- Don't have any block glass mortar sitting around...Just thought it would be easier to get the right sand, lime and portland already mixed. There are several posts where people are concerned that they didn't get the correct type of sand (silica), and then there's the issue with lime--lowes and home deput both sell it in the garden section but there's an additive of soluble calcium. Not sure if that will mess things up but I get concerned when it's not just straight lime.

+1 on the homebrew. Better to be safe than sorry.

Re: NW Ohio Build - Opinions welcome

I don't think there is any problem with the wood - given that you've got 4 inches of concrete and 4 inches of insulation. It will barely get hot if at all

Not sure why you are looking to use glass block mortar. I assume because you have it already? I would go with homebrew. The mortar line item in your budget will be about $20 total. Really not a place where it is worth experimenting. But what you describe sounds pretty much like homebrew sans the fireclay. I would get that from your brick cuttings. Not worth buying a bag and then throwing away what you cut from the bricks by the bucketload.

Re: NW Ohio Build - Opinions welcome

I would not sleep if I had wood on the base of my oven, I was thinking about doing the same thing you did, but I decided not to as I would not sleep at night. Why did you decided to put wood on the base? Let me know as I think it will be easier to do than concrete. Thanks, by the way its looking awesome!

Re: NW Ohio Build - Opinions welcome

Anyone have any personal experience substituting glass block mortar for the portland cement, lime and sand portion of the home brew?

and going with .....

3 part glass block mortar (pre-mixed)
1 part fireclay
