Lawson Coal Stove

I watched his video and was thinking you could probably add a flat gasket to make the doors airtight.

Also it is nice that there is an access that allows shaking the grates without opening the ash door.

If your shop space is insulated well enough it will probably throw enough heat to work for you. This weekend the stoker in my 24 x 20 well insulated shop heated it to 60 using about 40 lbs a day. And that is with plastic sheeting hanging in a 5' open doorway to the uninsulated 24 x 24 garage.

I wouldn't be too concerned about the thickness of the steel as most of the barrel is lined. Much like a Godin. The grates were what made me interested in this stove. I started out with a Petite Godin which, for it's size,made plenty of heat. But the shaker grate system left a lot to be desired. Over nite burns were impossible to shake down . I'd end up unlatching the front of the burn area and gently shovel the ash out hoping the burning coal would bridge till I could get the front latched back in place. Sometimes this went well ,sometimes, not so well. Needless to say that stove didn't stay long. It appears the Lawson would be easy to extend the barrel with heavier ga. steel from the top of the lining up, more radiating area, and perhaps do something in a configuration like a Glenwood 109. I'd like to have a hands on before I put up the $600+ for a stove to experiment with.

The 1"+ 3000*F refractory lining makes the metal thickness a non-issue.
In the you tube video near the ending there is a 45 year old unit with fire in it, it's showing some age but is looking pretty solid...refractory lining is key to longevity.

It would increase the heat output if a backpipe could be added to it.

What would it have cost them to make the stove out of 1/8" steel? A dollar? Two?

Why would it be necessary? The Glenwood 6's and 8's and others like them are all over this forum and they are of the same design, a sheetmetal barrel. That's pretty good for stoves that are 100 years old.

The one difference I did notice was this Lawson stove has the refractory liner clear up to the load door and beyond. A person could really load that baby up with coal.

Flat gasket for the load door and some Rutland 600* silicone for the ash and shaker door properly applied and it would be pretty much air tight.
