We have been working for a while on a another style of "ship-able" core. We will have it in 8,6,& 4" versions. More pictures of the 6" core can be found at this thread over at the rocket stove experimenter forum. It includes the 2ndary air p-channel, tripwires & vortex ends.

Shared! Nice for elders! Do you need beta testers?

Thanks, for offering, but we don't need beta testers. These cores are the result of Peter Van Den Bergs designs and test. You can read the long development history if your interested here...

We expect to be shipping in the next 2 weeks in 4",6", & 8" sizes. Attached is a picture of the 6" core.
