Grate Casting Issue

Modern and vintage hand fired coal stove are similar to a wood stove and in some cases can burn either. They need to be regulated and fed by hand usually every 12 to 24 hours depending on your usage. They require no power to operate making them ideal for rural settings with long power outages.

Hello guys I have a question....I just picked up my furnace (Brunco) and was looking it over and notice that the slots in the grates are flashed over some from casting. I was thinking I should take my hand grinder and grind the flashing away to make the slot openings all the same so I get a better air flow up through the bottom of the furnace. Do you think this a bad idea? I'm not going to make them any wider, just remove the excss metal. Ssettle

I would do it also, sounds like they just did a poor job of cleaning the castings

Smoother is better. Sharp edges cause hot spots which weaken metal. Better airflow means better heat and better shake downs, of the Anthracite kind!

Do you have a photo of the flashing?? It won't do any harm.. but I think the coal fire will burn off any small thin flashing with the first few fires.. Might as well grind it clean.. it's too warm to burn coal yet..

It would be a good idea, it may just cause some grief if the grates choke up on ash. I would remove the parting line too, just lightly enough to make it disappear. It is a good idea to fit them and check clearances (they grow a bit when they heat up), you don't want to find out it's rubbing somewhere with a full load of coal in it. Don't forget to go easy with the first fire for a while so the grates season nicely.
Nothing is impossible for people who don't have to do it themselves.

Gas grill does a nice job of breaking in the grates, just need one big enough.
