Is the DSR2 RC1v8.skp the most current version of the design? Do you have an "open version" .skp? Assuming the design is considered stable at this time, I plan to begin construction on the upgrades from my current DSR soon. @skshel I’m not able to find that sketchup file you refer to. Can you locate it for me please? Cheers!

Edit: The file can be downloaded using this link. It's in SketchUp version 8, the lowest commom denominator.

Health is flaky lately to say the least, resulting in very limited energy. And as a consequence I am sleeping a lot. In reality the drawing you mention is the latest (published) one but new insights led to a more complete design. I can do an open version drawing very easily, just give me your system size. A closed version is lots more complicated due to the air inlets at the front side of the firebox. Because of that making a drawing would take more time, hard to say how much. So, which one do you prefer?

I'd be very happy with the open one. I guess I can figure out the air inlets for a closed one myself based on your pictures, info and my testo. Or do the sizes, dimensions and features differ too much from the open system?
Take care of yourself Peter. Get well soon!!

peterberg I'm sorry to hear about your health issues. I hope you get to feeling better soon. I have a 6" system and am planning an open system. Once again, thanks for all that you do.

Or do the sizes, dimensions and features differ too much from the open system? Take care of yourself Peter. Get well soon!! The open system and the closed one differ quite a bit. It isn't possible to convert an open system easily. I would say a two-fold door seems to be the best option. An inner door open as a spark screen to protect from flying spraks or coals that might roll out. And an outer door without glass that's closing tightly when the burn is over. So there is no size and placement of air inlets to consider, the floor channel won't burn out because there isn't any, no glass breaking risks. From an operator's point of view it's quite simple: start the burn with the outer door a quarter open and when the burn is healthy on its way open the door fully and enjoy an open fire. My health situation won't improve in the immediate future, I'm afraid. Simply put, there's something wrong with my personal plumbling system. Which of the parts and its possibly interaction is unclear, investigation is in the planning.

I have a 6" system and am planning an open system. Ok then, I'll try to do a drawing in the coming days but don't hold your breath. You are planning to modify the setup you have there, isn't it? No bricks but geopolymer parts?

Yes, I'm planning to modify my existing DSR into a DSR2. No bricks, just geopolymer. Correct.

an open 6" system would be interesting

Should I include a "Stumbling Block" into my upgrade. I understand that the testing is incomplete on this issue. peterberg what is your "best guess" as to whether it will improve performance? From my perspective, I can add it now fairly easily during the upgrade but I CANNOT easily add it after the upgrade. If I add it now but it is determined to be a problem, I can cut it out at that time. It all comes down to how I structurally design the geopolymer.

In my opinion the stumbling block is important in an open system, presumably due to the higher gas velocity. So if your question is "should I incorporate it into the upgrade" the answer would be yes, definitely.
I think I can do the drawing tomorrow and the stumbler will be in there for sure. Second goal would be a brick version of a 6" system. Not specifically for you, by the way, but to provide alternatives in general.

Simple open system drawing is ready. It's a 150 mm (6") system, the inside of the riser stub is thought to be lined with CFB or superwool. It's in the drawing as a U-shaped white item. Wall thickness is drawn as 40 mm. In case imperial measurement is preferred just open the drawing, select the entire core and copy it with Ctrl-C, start a new drawing in inches and import the core with Ctrl-V. pberg0.home.xs4all.nl/pictures/dev2018/DSR2/DSR2%20openv8.skpOf course there should be something like a door or glass window or CFB panel in front of the top box, just mentioning it because it isn't drawn. As it is, given an adequate heat extractor is used this core is able to achieve an overall efficiency of around 90%. There's one test which is omitted in the development period. That's to check whether or not the thing would work satisfactorily using no lining inside the riser stub at all. I could take it out very easy but in order to get it in again I need to dismantle the setup for a substantial part. And besides that, it's too warm to run a heater now.

peterberg Excellent! That gives me what I need to get going. Thank you.
