4 days and burning good!
Thanks to all who helped me out.
I now use the 2 hand shake method and gently is the key.
I had my grate nub welded and seems to be holding up.
I drilled and tapped the back of my front grate to hold the nub of the rear grate firm for a much improved shake.
I drilled out the center holes and ground the side slots just a bit to help the ash come through.
I now poke up through the holes and slots from the bottom after every shake. Anywhere I dont see a nice red glow.
All this seems to have improved the way this furnace runs.
I am using Reading nut and it seems to be burning down good. I have never had a clinker so I think it was more me than the coal.
Got it all piped into my main ducts over the weekend. Enjoying the cold weather and keepin warm.
The Arabs will have to keep the oil I was gonna buy this year.
