Oh sorry, Max and all; We always say “a picture is worth 1000 words”, but may it takes more than just a picture.
The area between the two rings is just that; a ditch that allows condensate to run off the lid and into the ditch and then through those “half eaten away” holes allow the condensate to go through onto another plate which feeds the condensate out to the main condensation ring. In photos 7 & 9 I believe you can see the outside ring has about 1/4 in. flat surface. That is the sealing surface on the main lid side. That contacts the rubber seal on the top side between the two rings.
Ok! I’m back. It is chilly and raining, so I put my winter coveralls on and went to the shop. With my health what it is, the coveralls made me feel like a “bomb squad” person going in to disarm a bomb. Those coveralls are heavy.
Anyway I was able to get the gasifier torn apart. I found a place on the ring that holds the hopper on where it gave the appearance that the seal was squeezed to the point that there was no calk in that area to seal it. There was no “white ash trail” there but there was a black/brown char look on the surface where there should have been calk. I am going to have to give some serious thought as to how I fix this. There may be a problem with the ring holding the fire tube also. It was dark in the shop by the time I got that ring pulled out.
- Way back in post 903, I unscrewed the nozzles and took them out. I have no “inside micrometers” any more so I found a drill that fit the hole perfectly and it was 5/16 in. dia. So the de facto nozzle-tip diameter is 5/16 in. (They say when you lean a new word it is good to use it often, to remember it and get use to using it )
I have a lot of respect for anyone who speaks more than one language. Even the Spanish/ Mexicans that are flooding our country, IF they speak Spanish AND English/American, I feel inferior to them in that category.
- Until my truck is back on the road, I believe there will be more speculations. As a rebuild, the question of dimension for all the various parts will probably get reviewed and we will have to speculate on staying as things are or to change.
Just questions and thoughts; Kristijian and JO have gone to a “grateless” design. At this point should I consider that and what are the + &- 's ? Clean the ash pit or clean the cyclone. I actually have a plate in my ash pit where the gas leaves it to stop ash from coming directly off the grate and out to the cyclone.
If and that is a capital"IF" I end up having to make a new hopper which path should I take? 1. a good condensation collection such as JO’s, or 2. a heat mantle around the hopper-- sorry but the “plank” is not in consideration. I do like the story about the race driver who created a “modulator”. We have had a few attempts to duplicate a modulator but I don’t think any have incorporated all the modification to closely copy it.
I do not think you will see me using a feather bow as you have described it to me. The tension on the lid is all determined in the original design/build. If you want to change the pressure on the lid, you have to go back and redesign ; the width, thickness, curve, and/or the distance between the latch and hinge. For mine when I want to change the pressure all I do is change a spacer under the spring. Ah well; Time to say goodnight. TomC
