    Default New 2x6 arch for "new" pans

    Purchased a used sunrise 2x2, and a used smokey lake hybrid to replace the old 6x6 Grimm syrup pan that we have been boiling on(attached picture). planning to replace the threaded fittings with sanitary fittings on the smokey lake pan. also building our first metal arch. Previously we had an arch built out of cinder block. Any suggestions or observations welcome on our progress.

    Today's progress, not sure why the pictures are uploading on their sides, but you get the idea. I saw some plans that this is roughly based upon, no ramp. does anyone see a drawback there?

    What is the width of the new arch? It has rather wide angle iron, I hope you are not planning that much overlap (pan on the angle iron). The more overlap you have, the less heat transfer to the pans. Also, is that a brace across from side to side, factory built arches don't have a cross brace, at least my old 2x6 and my currant 3x8 don't.
    As far as the lack of a ramp, you still want some ramp for better heat flow to the pans. That being said, when I added air over fire (AOF) I built my back wall up so I have an air tube around the fire box with nozzles every 6" , aimed down at an angle. My back wall now only has a 4" tall ramp and it works fine. I don't know if it would be good without the AOF under high pressure.

    The top rail is 1.5" angle, the ”legs" are 3". The dimensions are 24 wide(couldn't make it much wider without extending the fittings on the pan. I have some angle left so I can add a short ramp. I'll be working on it this afternoon, I'll post som more pics.

    Flipped the arch over today to check the fit of the pans. Just need to go through the barn and dig out the rest of the plate for the back. I had 1/4" on hand so it's getting heavy to move and shift around, by the time i get the doors on, and the rest of the firebox closed in it will be the job of the tractor.

    Looks to me like its coming along nicely. You should be set for next season well ahead of schedule. Are you going to line it with ceramic blanket and fire brick?

    I have firebrick to install, I need to order ceramic blanket. I left enough space under the back pan so I can upgrade to a pan with 7" flues, so I will need to build that up, maybe vermiculite? I used "rockwool" to seal up the old cinder block arch and it worked well and held up to the heat, not sure I'll use any of that in this build. It is going to take me a few days to work out an airtight door, grates, and blower attachment. I'm trying to hurry because I know me, and I do procrastinate, lol.

    yeah me too. Always wait until the last minute. I am getting better though, Picking up tubing and stuff for installation this fall. Be ready to tap next spring.

    With the 1.5" overlap on the angle iron, the side channels will not boil as well. My 36x96 arch (plus rear base stack area) has a width of 38", with just 1.25" angle iron, thus I have just 1/4" overlap. Can you cut the top angle down to maybe 3/4"?

    I may be able to shave it down some, but I have fire brick in there too, so I can't go passed that. I probably could have made the arch an inch wider but I wanted to make sure the sanitary fittings had enough clearance. Maybe I can bevel the top bricks or cut a full brick in half at an angle leaving it like 1/2 inch on one end. I have a big wet saw to cut them.
