I'm thinking about welding up that seam in the barrel. I wonder how much air gets through there?

isn't the seam on that barrel a double lap hem ? is so it probably isn't leaking and even if it were you will need to be a pretty welder to weld a bead down one of the "open" sides with out distorting that thin metal.

not saying it can't or shouldn't be done but it will take skills and, maybe you have them.

i had one of this type "square" WM's and the seam was lapped in both directions and peened tight by a form press or hammered one or the other.

Yeh it's lapped and pressed. It's 38 years old though so its probably loosened up a bit. I'd tig weld it if I was going to but too late now it's painted.

Now that the bottom inside is painted I am able to see a pinhole that I didn't see before paint, so that will need to be welded up before I go any further.


I had a little copper paint left over so I hit The Elm stove window emblem.

show me a pic of the pin hole and i may be able to give you an alternative.

It turns out it wasn't really a hole. There were slots in the bottom of the barrel and the pan that gets pushed up into the barrel to form the bottom didn't cover one of the slots entirely. I think that slot was longer then the others. I filled it in with some weld just the same. So I just have to wire wheel and paint the other bits black and it will be ready to assemble. Don't know when that will be. All the activity has flared up the torn meniscus in my knee and I've really been slowed down by it.

I have this stove, and have run 12tons of pea coal thru it in the last five years. Mine got a complete restoration, it was a mess when I got it, and I made the missing chimney bricks and flats it needed. It has a Magic Heat Unit, with an Adams draft-o-stat above that. I reversed the boot in order to have a larger stovetop. This made it possible to have a cleanout tee and damper right out of the oval pipe connector. Square nuts and stove bolts may be replaced with black oxide oval head phillips drive machine screws with lock washers and hex nuts. I used flathead allen drive screws on both cast door flanges, as well as new hinge pins made from new clevis pins. The top door was clamped in place and hinge holes carefully reamed to get a better fit. I do not recommend welding the lock seam on the sheet metal body or trying to seal the doors. Coal needs air for good steady overnight combustion- I can usually almost completely shut the bottom draft, top draft always stays shut and close the damper 98% for an overnight burn. You must slowly develop the themal mass needed to support a full loading in the evening by adding the coal layer by layer and allowing it to have impurities driven off, and the gases burning evenly in the four corner chimneys. The final layer load should only be to the top of the fire brick. Once it begins to coke off nicely you can close your draft and damper down for the night. A flat steel poker, long enough to stab down to the grate is helpful to creat air flow. Only shake your grate down a couple of times in a 24 hr. period. The most dangerous pRt of using this stove is enptying the ash pan. Expect to let the fire go out about every fourth morning. Open your center grate slide, and using your poker, push all the clinkers out, shake the grate well, empty the pan, and light a fresh wood fire to start it up again. This isn't a big job and goes pretty quick. I burn bit B coal from Wolf Mtn Coalyard in Sheridan Wy .,and it is excellent coal. $65.00/ton

The black oxide fastener hardware was ordered from Fastenall.

Thanks for the info. I got a bunch of black oxide flat allen head screws but the only nuts I could find that size are zinc. They might just be coated I'm not sure.

I've noticed that the metal on the barrel where the square nuts landed is pretty distorted so I am considering making some backing out of a piece of strapping for the nuts to clamp down on.

I was also kicking around the idea of using fiberglass tape instead of stove cement to seal up the joints. It looks like trying to seal the top of that stove is going to be impossible. I don't see how the cement will stay put while trying to get that top cap in place. Fiberglass tape might be a better option.


It's interesting that your boot is reversible. That would be a great benefit for my application since I have a very low basement ceiling and a vertical rise really limits my options. It's going to be a very tight squeeze just to get the mpd in there and still have clearance to the floor joists. I'll probably have to put heat shield up as well. I'm pretty sure this boot doesn't flip.

The coal we have here is very poor bituminous lump. I haven't burned any yet and I have only found one post by a member here about this coal. He mentions it didn't burn very well at all and had terrible bridging and clinkers. I can't remember his stove but I do recall it wasn't specific for burning bit, I'm thinking it may have been one of those furnace type wood stoves touted as burning coal as well, so maybe I'll have better luck. I'm hoping I will as it's just $70 a ton which will drastically cut my heating bill. I'm currently burning wood pellets and the price is ridiculous compared to when I started burning them.


BTW I also have a Magic Heat exchange. I am hesitant to use it as I was thinking the tubes might be a catchall for soot. I also have the vertical challenge issue. If I could come up with one of those reversible boots I might be able to use the Magic Heat.

Your boot is reversible, try it. You may have to do a bit of filing to get a decent fit, but they are made to be used either way. The oval steel stovepipe connector I used is thru bolted to the flange on the collar and sealed with furnace cement. The cast door assemblies top and bottom were smeared with furnace cement on the flange that bolts to the stove body as well. Instead of fiberglass tape, try putting a bit of furnace cement forced between the cast iron top and metal flange. As you tighten the bolts around the perimeter you can smooth the squeezeout into any little gaps, then clean off the excess. Makes a neat sealed job of it. I will post pictures of the horizontal boot and pipe later today.

I'll have to inspect my boot. I seem to remember one side being longer then the other. I'm afraid I haven't been able to get down the very tight spiral stairs to the basement due to this damn torn meniscus in my knee. It has no hand rail so I'm very reluctant to try. I used to run up and down it no problem up until a few months ago. I never realized how dangerous it was not having a handrail until I became one legged. If I can get back to being able to reasonably use my leg I've come up with a plan for an elevator I'll install. I'm getting older and I'm going to need to get down there without issue. I've got my hobby shop down there so it's imperative I have access.

Thanks for the Great Info on these WM stoves. I have the little WM-414 and will eventually burn a fire in it.

Oh, and the boot does flip to allow either vert or horiz. outlet on this one. :)

See page 2, no.3

If you cannot empty the ash pan outdoors, consider having a second ash pan made (I made my own) and have a rececptacle that you can set the pan of HOT coals and ash into and close with a tight fitting lid, and let cool before emptying.

Thanks for the file. That refers to a 523-R. My stove is 523-B. I'm not sure what the difference is. I'm still unable to get down the stairs. Hope we don't have another January tornado...lol.

Same stove- as to using a magic heat unit, I've had no problems with it. Works very well. From stovetop to ceiling here is 54". All the vertical pipe, tee with bottom cleanout cap, vertical stovepipe from tee top to underside of magic heat, and vertical stovepipe from top of magic heat to ceiling thimble is suspended from the ceiling thimble. This allows you to slide the stove into to round to oval connector into the boot flange and bolt them together. A bit fiddly getting the lowest section of vertical pipe cut to the right length, but once it is, the stove will mate to the tee very nicely. When the stovepipe gets cleaned, it's brushed downward from the roof (20ft. from tee to cap)
I tape a garbage bag onto bottom of tee after removing the cleanout cap. Then the pipe is brushed down to the magic heat. Then using the magic heat tube scraper vigorously, all the soot ends up in the trash bag. No mess at the stove. 45 minute job.
