- I just couldn't help myself, so I went all in on this build by adding ceramic insulation and fire bricks to replicate a real legit maple syrup evaporator arch. Hope this video helps anyone that is wanting to build one of these. Thanks for watching, and please subscribe to our channel!
That's beautiful work!
Well thank you! Thanks for visiting my channel
I pulled the grate out of mine after a few boils last year and just use firebrick on the bottom and up halfway on the sides. Due to limited room inside the barrel if burning hardwood it needs cleaned out a couple times during an all day boil, recommend burning softer woods that turn to ash instead of larger coals. I burn a lot of pine and it never needs cleaned on an all day boil. Works out great. I get 5 gph boil rate 👍
I haven't had to clean out yet surprisingly
If you could do away with the draft feed and put a forced air blower it will help increase your boil rate. Raise the grate up and create a chamber under it to allow air to be forced up through the fire. You could probably get away with a 20 - 30 cfm fan. If it does 5 gph open draft it will probably do 10 gph if you get that door closed and force feed the fire with a blower.I have an 8 foot arch, I run my stack temps right around 1000F, if I just open draft , the temps drop down between 500F to 600F. Yea it's hot and it boils but nothing like when the blower is forcing air up through that fire.
Yeah I am planning on adding air. I want to get the Dauntless Arch from Smoky Lake in the future so didn't even want to insulate this one but figured why not. Thanks for the input
That’s a sweet set up! I like how you did the bricks on the final part of it leaning against the side. That looks like a Smokey Lake pan? If it is, I run the same flat pan on my Dauntless.
My evaporator is fully insulated like yours, at full boil. You can touch the outside of it briefly but it’s not scolding hot. That ceramic insulation is amazing. Great video.
Thanks for watching. Yes it's a Smokey Lake pan, not as big as yours. I'd love to have a Dauntless. Future investment for sure. This rig works pretty good if I can keep a nice dry wood supply feeding it and a little shot of air with the air compressor once in a while. Best I've ran was 6 gph for about an hour, lol.
As long as you do a realistic test burn, I wouldn't worry about removing the paint now. if it starts burning off during your good realistic heat test burn. I'd keep the test burn going and burn it all off, if it doesn't burn off, good on you.
Made it through 8 boils and paint looks perfect still.
Its it any better than a bone stock barrel?
I'm getting 5-6 gallons per "hour" at least without blowing air in. Once it gets going, it runs super hot. Wood catches on fire instantly
@@219jello Did you mean 5 gallons per hour?
@@outdoors-fun lol, whoops! Yes! I'll edit
@@219jello Ok, thats what i get with my stock one as well. Your video did inspire me to add some fire bricks along the bottom, edges, and back.
@Quabbin with Coop I can't compare it to a stock unit because this is the only one I've built and used. Theoretically it does hold heat inside better and does get a natural draft flowing out the pipe due to the shelf I built in the back. Making the fire box area smaller does save wood, but doesn't hurt combustion and actually helps it. When this rig gets up to temperature, the boil is amazing. I bet if I do a better job of of feeding it wood, I'd get upwards of 6+ gph.
