Coal grate pictures??

[brian-in-maine]

Hi everyone,
This is my first post, very happy to have found this forum. I have a 1979 HS Tarm 55 that I have been burning wood in for years. I would like to have the option of burning coal but I only have wood grates. I heard the coal grates were hard to come by so I was thinking of making some. My question is there any pictures out there of a set?
Thanks

This is a 404, but the grates were very similar....
Here is the basic part (upside down)
(broken link removed)

Also, here is from the bottom in a 404 (grates were almost identical except the shakers were in the center instead of off to the side.


If it were mine, I would rig it up to burn coal without the hassle of shaker grates. This boiler could easily be poked and knifed along the grates (through that little front jail door)....

Funny was at woodsman's today getting a new flag.

Thanks for the pictures. Is there anything that goes in the firebox to keep the coal in a pile? Shouldn't the coal be in a deep pile?

This should answer most of your questions - your boiler is pretty much identical inside......

So you can optionally place some kind of baffle to make the firebox shorter and also make it so you don't easily clog up the exhaust in the rear bottom of the boiler. You need to make up some kind of a sheet metal flap which installs under the grates and makes it so the combustion air (most of it) is forced up through the coal bed instead of bypassing it. The official coal baffles had such a swing plate along with the rear baffle.

Hope that helps!

Thank you! The pictures were just what I needed.
