today's progress
Well you asked for pics of mistakes and all so here you go:
In keeping with your request the first one is of my first mistake. I'm sure it will be the first of many.
The first pic shows the oval cutout isn't centered in the end. Purely an appearance thing but I'll see it every time I go to fill it.
The second shows the outer jacket from the other end. The tank I got was twice as long as I needed so I had to cut it in half. I'm reminded how nice a tractor with a loader is, I'm currently without. I'll be cutting a 20 inch slice off of the remaining part to cap the open end. The scrap piece is slightly larger diameter than the end I'm using. When it was originally made one section was fitted inside the other rather than butted together. The piece that's left over after I cut the slice off the end will be used for a fish tank for my aquaponics system.
The third shows the former resident of the tank. The warmth of the boiler will come too late for him though.
The fourth shows the tank I'll be using for my burner box. It's quite thick walled and will hopefully last a long time.
The fifth show the edge detail of the tank shown in the fourth. This one is welded at the edges rather than crimped and welded as the thinner walled tanks are.
This is loosely based on plans I got from DEB Design.
Any thoughts on the use of firebrick and or a grate in the burner box?
I'm installing a "smoke director" that will cause the heat and smoke to make almost 2 full passes of the firebox before going out the flue.
Any thoughts on putting "crossover pipes" above the director?(to avoid direct flame contact)
The plans call for a water jacketed door to prevent warping and to make the door no hotter than the water temp rather than possibly glowing red hot.
Any thoughts on the water jacketed door?
I'm planning on an aquastat controlled fan for boiler water temp control. Think this one is big enough?

I've got hopes that this unit will heat my garage, my house and a small green house. If not I guess I'll have to build another one!!
I'd have gotten much more done today but I got sucked into helping a friend of my wife's move. The friend didn't answer her phone all morning then decided at 1:30 that she wasn't moving until Saturday. This would have been the 4th time I'd helped her and the 7th time my wife would have helped. Talk about abusing the privilege!! If she does decide to move on Saturday she'll be doing it herself without benefit of me my wife or my truck!!
