I suppose its about time for a pic. I'll get one up in the pics thread.
This boiler is very well made, but it seems like the coal was an afterthought. The firebrick on the sides lay at an angle and also rest on the grate frames, no problem on the sides. On the ends, the three bricks are vertical and have to be held in near the top with straps of steel. These do not last long in a coal fire, believe me. To top it off, the ends of the grates are actually under the firebrick. When you shake it it tends to nudge them around and you know where this is going. Bowed bars, cracked brick and brick edging out of place. This things getting an overhaul or replacement.
When I was fiddling around, I found two 1/2" holes in the top of the airbox that feeds the ashpit, gadzooks the dreaded overfire air! Tapped them for 5/8" NC and plugged them. I hope it improves my burn, we'll see.
