stone built arch

[BHMC]

I came into some pans 2x6 raised flu...I need an arch and was going to build one. Then I had an idea of building a stone arch. I have a supply of field-stone and an arch front and coller. I could basically build a rectangle from stone and step it up in the rear. I would use some angel iron to shelf the pans so they get the full amount of heat under them. I also think it would be a little different than a normal run of the mill arch. Thats the concept...Let me know your thoughts PROS & CONS. Thanks

BHMC , Just my thoughts ? Pros -no cost .Cons -Unless the field stone is heavly insulated and fire bricked (and even than?)May get hot ! crack and blow apart !.Concret blocks ( heavly insulated and fire bricked ) even crack sometimes ,but work well and are easy to frame with angle iron /front door /rear stack .
However ,Iv'e seen a many a thing work, if a little thought is put into it ...So if all u gots is field stone ? Wear football gear an helmet ? lol .
But it dose sound like u got a nice start with the pans ! Good luck tappin !

I'm with Ed in that the sustained heat that we generate making syrup could destroy the field stones. I'm going to run on dry stacked cement blocks again this year and instead of losing 1/4-1/3 of them from the heat I am going to try making temporary side heat shields inside my arch with some scrap metal and ceramic blanket. Next year I'm hoping to build a steel arch and reuse the blanket.
I've thought about making a permanent block or stone arch but don't have a dedicated spot for one. While not easily moved, a steel arch would be more portable as site plans change.

The other con to using masonry or stone is the heat it stores. All that mass stays hot for hours after you're done firing whereas a steel arch cools off and stops evaporating faster.

It all depends on your take on the pros and cons. Any way you go there are a lot of great folks and excellent wisdom around this site. Good luck and let us know what you choose and how it goes!

I had a friend build one out of field stone and it worked fine, the only problem they had was with the mortar joints cracking. They fixed the joints with a different type of mortar and it held up pretty good. Just requires a little maintenance from year to year is all.

What ever you do don't use river rocks they can and will explode don't ask how I know that:o

Guys...Thanks for the info....One thought I had was to obviously fire brick it, but also to place a fire blanket between the stone and brick... Thoughts on that idea?

[Bucket Head]

That would be a good way to go. Its basically what everyone does with a traditional arch- so the archsides are protected from the high heat. The bricks protect the insulation from getting damaged when fueling. The only concern would be are you mortaring the bricks in? Maybe you mentioned how your doing it and I missed it. The blanket will soak up moisture, so you would'nt want it 'trapped' behind unremovable bricks. I assumed the earlier mention of the steel panels and insulation was removable, seeing it would be outdoors and not in an arch with a roof over it keeping it dry.

Ok lets reset a little bit...I have a friend who has some granite slabs. They are 6" thick and 8" to 10" tall. So I was thinking place three or four high and hang the arch door on the front so the door and draft set-up would be there. I could use angle iron to make a shelf on the inside to place the pans on and also make it level. The only concern would be making sure I had enough room to clear the draw-off. I would still brick the inside. So think on that and let me know...Thanks for the info so far.

What you're doing is pretty much the same as what the guys with the concrete block arches do and those work just fine. I had one for a season or two and there are things about it that I miss. If you brick and insulate the granite so it's not subjected to intense heat it should hold up great and you'll have a pretty sharp looking arch.

I'm thinking on doing the same thing, or possibly brick. I have to get my stone and timber shack done first, BUT;
Air space is your best insulator! If there is a way to use full sized firebrick and leave about a 1" air space, you'll get great results.

While laying awake I'm thinking about this delema, as stone work is hard yet rewarding, but to watch it crumble as your boil,.......NO WAY.

I would try to use "smaller" field stones just so you can get the "look" but not toop big as to create a 5' wide evaporator for a 3' pan.

Just some thoughts.

PLEASE post photos!

Good luck!

Just thought,........I used type S mortar and this is the first winter for my walls and they seem OK. There may be a "refractory" type cement that you could use or "blend". I don't think anyone will tell you blend them but hey this is Maple Syrupin' Homemade stuff!

This is a friend's homemade arch. The only problem he had was he didn't pour a footer and the frost heaved the pad. Had some work to keep the pans level.

This conversation is got me thinking, the pictures of the brick arch are very much like what I am looking to do this summer but I was thinking of using concrete block. Do you guys think I could only use fire brick to line it and keep the block from cracking? I batch cook on a flat pan about 2x7 or so. Right now the fire box is just angle iron with 10 guage steel plate, been cooking that way for years but in the mood to make somthing nicer but not taking a loan out!!! Looking for as many ideas as I can get. I do need to build 2, 2 pans..... Right now we use about 4 foot long fire wood to fire with, fill up the box and let it go....

Here is the brick arch i just built last week. Its not perfect considering I have never laid bricks or blocks before this. I haven't used it yet. I need to finish the chimney and hopefully boil tomorrow.

Here is our brick arch. Made with fire brick, solid concrete block and exterior brick. When we burn maple or oak we smoke meat in the smoker. There is a griddle on top as well for pancakes. I cant get other pictures to download and they should be on our website and facebook.

We have 270 bags and buckets out.

Type "S" is high strength mortar, not high heat, but it should work fine. Your local masonry supplier or block yard should have fireclay, which is what is preferred for direct heat applications. Be cautious of granite slabs; make sure they are throughly dried before you fire it up for the first time or they might crack.

I work in the stone industry and my plan for next year is a soapstone arch. I'm thinking of using it as walls and floor captured on the corners with angle iron. Soapstone is used to make wood stoves and should double as both the structural side of the arch and the fireproof insulator, replacing both the firebrick and steel sides all in one material. Oh, and did I mention my cost....FREE!

That's awesome Josh - do you have any close up pics of The Maple Grille setup? I'd really like to have an arch that I could use for grilling, smoking sausage and bbq the rest of the year so I'm curious where the smoker is in your rig.

My latest crazy thinking involves an enclosable 4 season screened-in patio around the arch that would double as a sugar shack.
