Information overload here, there is a ton of good stuff here, so much so that I don't know where to look.
I obviously found this rocket stove forum but hope there is a basic project page where I can get an idea about perlite based stoves, particularly mud recipes as there is no need for me to reinvent the wheel.
Hi John; Welcome to Permies!
And Welcome to the wonderful world of rocket science!
Were you wanting to cast a rocket core with perlite and fire clay?
There really is no exact recipe for that.
The idea is lots of perlite with just enough fireclay to bond it.
When I built my first perlite clay J tube core, I started with a 4' bag of perlite and one #50 sack of fireclay.
I know I mixed it clay heavy and I still had some of both left over when I was done.
There is a great book by Ernie & Erica Wisner called The Rocket Mass Heater Builders Guide, readily available.
It is highly recomended.
My next project will be a stove instead of a heater, my mobility and weight lifting ability is limited at the moment. Maybe a heater later on.
I prefer to read but a thirsty man will take what is offered. Lately I have been watching Youtube after discovering it can be played at 1.5x or even 2x speed. I get a bit impatient when a fella building a pizza oven shows me every handful of mud from first to last being put it place. Maybe they get more ads if they drag it out.
Also you said the Wisner book is readily available. On this site?
Thanks for the video, I enjoyed it. It was well done as it didn't drag on showing every cut and every screw being installed. I tried to watch part 2 but the volume was so low I could not hear it. I will need to find a compressor/equalizer with an input gain boost capability for Linux. Sorry, TMI.
Not sure which flavour of Linux your running, but on LInux Mint you can amplify the sound at: preferences/ sound/ settings.
Just remember to turn it down when your done or you might risk loosing an eardrum or two when listening to something else!
