Wanted pictures of RMH innards

I was wondering what to expect after my RMH has been burning for some time. Anyone open up a RMH and take pictures?

Here's an uninsulated riser after twenty burns, and a pic of the riser insulated. I haven't got one of what it looks like now, but maybe after a while I'll tear into it.

Marty , here is a pretty good thread with pictures and discusion.

Well, what I was afraid of happened,,, Too much fuel, not enough air. I'm burning a mixture of sawdust and waste vegetable oil.

But being over eager for heat, and not wanting to add fuel every 15 minutes, I dumped in up to 6 scoops of the mixture.

Before adding an exhaust fan, I would get so much flame that it would shoot out the opening at times.

Piling that much fuel restricted air and much black smoke out the chimney.

Having burned WVO/Sawdust before, I immediately knew I must have some soot buildup, so I cut the top off the barrel and whoa IT'S FULL.

The pictures in the above post are after maybe 20 burns tops,,, more likely 10 burns,,,

Any suggestions? should I feed air into the heat riser, or the bottom of the burn chamber

Here's a picture of what the insides are made of,,,
