Oven Build in SC

Re: Oven Build in SC

Let me suggest that you not order the lime. Instead follow (Journeyman) post of 05-19. He gave an excellent to substitute guide using type N cement. You will have no trouble finding the cement. Be careful to not buy the mix which includes sand. Buy the cement only and add the sand and fireclay per The Journeyman's recipe guide. You will then be ready to mix mud. I am in the lowcountry and am expecting rain. Otherwise, I will be mixing mud.

Re: Oven Build in SC

That was my initial thought to follow his suggestion but I can not find any where it says that type n cement is 50/50 portland/lime. When I went to HD they said the Type S cement was 50/50 portland/lime. I would really like to read it somewhere but just can't find the info. That's the reason I was going to order the Type S Lime from Chemstar on line, to make sure I had the correct ingredients for the correct ratios needed for the motar.

Nice to see more South Carolinians on here!!

If I can be of assistance, I'm in Winnsboro.

Pappap, I have a friend in Andrews/Trio with all the bricks and firebrick on the ground... He hasn't taken the plunge... yet.... But I keep nudging him.

I'm in the upstate, Greenville.
Question for you country boy, did you use the home brew motar or a finished produt for the motar? I can't seem to find the Hydrated lime locally. I'm trying to get all the building materials first then start my long process of the build.!! any info would be helpful.

Re: Oven Build in SC

I used fireclay mixed with (I think) Type S mortar mix. Have had no problems whatsoever. I forget the ratio I mixed it in... May be in my build thread. If not, someone on here can answer.

The fireclay I got from Boral Brick for about $20/bag. I used two bags on the build.

The link which I provided in my second post The Five Mortar Types

Here is a link to the The Engineering Tool Box

If you search further and look into The American Society for Testing and Materials guide for Mortar Search for ASTM C270. This Link breaks down that standard.

It does however leave a little leeway for the manufactures to deviate from the formula.
Type S Cement would have a range of 1 Portland to 1/4 to 1/2 lime
Type N Cement would have a range of 1 Portland to Over ? to 1? Lime.

If you were to blindly choose any one manufacturers Masonry cement to make your home brew, it would be better to go with Type N.

Re: Oven Build in SC

I have question for anybody. I'm trying to figure out the angles that everybody seems to cut for the dome bricks. Has anybody ever created a spreed sheet on how to calculate these angles or is it a trial and error basis, and hopefully not to much error. I have 3"x4.5"x9" bricks. Anyway if anybody has any input it would be appreciated.

Thanks,
Steven

Re: Oven Build in SC

I found this online about the different types of mortars. The problem with walking into a home store (home depot or lowes) it doesn't show the breakdown on the bags. They only have the Type S mortar at Home depot in Orlando area.

That is probably because all of Florida is a Zone III Wind Zone. Type S is required in areas where walls could be subjected to extreme wind loads. Also, just a reminder: Mortar is made from masonry cement. Mortar already has the sand added so it would definately not be a source for home brew.

Re: Oven Build in SC

Well, the process has finally begun. I got the foundation dug out, framed and the plastic and rebar laid. It wasn't without casualty though, about my third spade full (2 min in) and a blast of water to my legs I noticed I pierced my garden irrigation line that I put in about 6 years earlier and thought was a little to my left. "NOT". Anyway a quick repair and I continued with the digging out the foundation outline. By the way, after the top couple of inches of South Carolina clay I believe it turns to red concrete!! but nothing a pick ax coundn't take care of.
Anyway this weekend I will be pouring the concrete for the foundation. Of course I wanted to wait till the predicted day time temps will be in the mid 90's!! Does anybody have an opinon on wether to use "High Strength" or Crack Resistant" concrete. I currently plan on using the High Strength for the cost savings (about $100)
Anyway the rebar is just put together with plasic ties right now. I thought I'd post the pics and ask for some feedback and opinions, if all looks fine I will wire tie it together tomorrow. Please, if anybody see any concerns please let me know. I'd rather correct it now then later!!
Thanks and I appreciate anyones input!!

Re: Oven Build in SC

Welcome to the wacky world of WFOs. Foundation base looks great. Nice shape. I just used standard bag mix and no issues. Not sure you gain value for crack resistant mix. Use the 100 bucks elsewhere. Umm 90 degrees with your humid weather . Good luck.

This was provided to me by Russell via another WFO JCG31. Its a useful guide to look at. Your build may not be exact to this, but it will put you in the ball park.

Re: Oven Build in SC

Phase One complete!! Poured the foundation this morning. It was going to be a warm one today so thought I'd get an early start. A couple of hired cement specialist showed up to lend a hand and they worked for very reasonable rate, beer and breakfast. As they kept saying, "It's 12 o'clock somewhere! Started mixing around 7 and finished around noon. Perfect! I still have a little grip left in my hands but not much. 80lb bags will give you a little kick in the .......between loading them at HD, unloading, moving to the staging area, loading them into the mixer. I have a little more sympathy and respect for all before me. Anyway, poured, screeded, about an hour later troweled and covered with plastic to keep wet and to prevent quick drying. Cleaned up the screeded material and the surrounding area. And now IMO a well deserved afternoon off.................................Who am I kidding, I'm still thinking about the WFO!!

I recommend Stay Hydrated and be liberal with the Ibuprofen! Your foundation looks great!
