Adding fins to bottom of flat pan (?)

I didn't worry much about the outside. A pressure washer gets most off. Inside I used diluted muriatic acid and a cordless drill with a wooden dowel and scotchbrite. Shines it right up!

Today I found out I can rent a set of Greenlee punchs so when I get everything figured out I can rent the tool. Its hydraulic so it won't take long to punch the holes out when I decide what I am going to use to do it. I also found thin wall 1 inch copper pipe today. I have months to get it ready for next spring so will work on it this fall or winter when I am bored.

Ken I would consider not waiting till the winter to do your handy work on that pan. If things go wrong your out of time.

There's that also. I am at least thinking about it. When I get working on it then it usually goes pretty fast as I have it all thought out as what will work best for me. or untill some genius comes up with a new plan that I try and copy.

building one of these seems like a good way to fill the space at the back of the proposed oil tank rig i want to build

question.... why don't you make syrup in the bottom of the drops???

thanks

When you pour the heat on there is nothing holding still in those flues! It'sall well mixed by the boiling. As long as the average in the pan is not syrup, it's not going to turn into syrup in the flues. Just keep a smaller pan to move it to for finishing.

tube pan evaporator ,not sure where it was. Just found the pictures,looking for 3 weeks.

That would boil sap for sure. All the heat has to pass by the sap before it can go out the chimney. Is that a WF Mason product. I did find SS tubeing today as I was driveing around I found a new and used metal shop and went in and asked him what he had. He had lots of good stuff in there and seemed like a guy who didn't mind being asked a lot of guestions.

The picture is kind of like we are makeing except that we only have one row of tubes going thru pan. Planned on still having flue gas go under pan as that adds surface area.

That looks like a steam loco boiler, but with a lot less tubes.

May make it a little tough to clean the bottom of the pan at the end of the season, but you are right that would have a lot of surface area.
