You keep up with those drafting and cad style drawings somebody is going to figure out how to mass produce the parts for your design Tone, thats some excellent looking work

Thanks Tom, just found a paper the other day how I did that in the old days. Ha, I dont even understand anymore 
. Now, it is just a flattened 3d design, nothing special. Boem boem pedal to the metal.
And you are right about the wedding ring. I told my newly wife my ring is dangerous in my work. Wow, I had better waited a few weeks, the little nitro bomb . After a few months she called me crying to please put the ring of. She got stuck in the house front door, and it hurts. But I was already used to it, and now 22 years later, he is still there. Haha and happy with it. Well, no jumping of a trailer, truck or whatever. Always keep your head to it, like it should with all you do. Time flies if you are having fun.

I was going thru some old pics from Argos 2014 and came across this pic of Marvin Willoughby and someone else’s hands that reminded me of you, Marcus

If you do not want your hands to get blacken by charcoal dust, well you better not do any wood gasification then.
RIGHT?
It is Better to have dirty hands, then a sinful blacken dirty mind. The hands will clean up much easier with a little soap and water. The mind takes the washing of God’s word Yesuha the Son to clean it. This has been my experiences any ways for me in my life.

My dad zapped his wedding band from a 12v battery on one of his racing boats. He still has a perfect scar around his ring finger. Luckily he had water to immediately plunge his hand into.

It just occured to me… how weard of a comunity we are to show off our unhigienic hands 
its what l like about this site.

Here’s my Table Router fingers. Chamfering bit grabbed my workpiece and sucked my fingers in.
I’m ashamed that I haven’t been making any charcoal lately. Helping my father move his camper to another location has taken up my weekends. Family comes first of course.

That is fun, i have one i call my angle-grinder-finger too… we are probably very much alike on this community
This finger seems to always end up in the way of cutting and grinding discs…around 6 times, 6 stitches at hospital, 3 at home, tape, crazy glue (meat glue, my wife hates when i call it that), and it still hangs on

Looks like there is enough subject matter here for a dirty and damaged hand thread. Ha! Ha! Only thing is, in this day and time, we’d better be careful showing our finger prints on the internet. We might become victims of cyber identity theft—nothing that a smear of charcoal dust wouldn’t remedy.

Still doing some drawings.
Tone’s gasifier design with a 12" WK Firetube diameter. Looking how the gases will flow through the firetube, restriction area, and out the vertical grate tubes. With air coming out the lower nozzle holes into the charcoal and the gases going out (edit:) (around the vertical grate tubes gaps) then on out the gasifier.

Did you mean through the verticle tubes or around the tubes?

He means around them, through the gaps.

Don, thanks I mean between the the vertical or around the tubing spaces. This should fix it and make more clear to understand.

This modification will make it easier to mount in a bed surface and lowers it by 4". This gives you 4" of more hopper space for fuel on top of the gasifier.
What do you think Tone is it going to work configured this way?

Bob, of course it will work, it’s just that the limited opening will probably need to be changed to a “restriction tube” so that it extends to the area of the bottom nozzle. Why? This prevents the tar from slipping past without conversion and you get a good effect of “cleaning” the lower part, the charcoal is reduced to very fine particles, which are easily moved aside by the vacuum and then up between the grate tubes, well, on the outside, the direction of the flow turns downwards and the speed of the gases decreases, thus the ash falls to the bottom, and the gas leaves the gasifier “clean”.

I forgot about how important it is for all the gases to pass level to the lower nozzle so no tars can excape with out being converted into clean gases. There is still 6" of space between the lower nozzle holes and where the vertical grate tubing starts. They are 2" dia. tubes, so that is 8" to the edge where the velocity of the gases really slow way down. This is where the ashes and fine char dust should fall down into the lower part of the gasifier bottom. I am planning on using just round piping and see what happens. With the full WK Firetube preheating build it should still make the upper nozzles air plenty hot. The lower nozzle air will not as hot, but it is functioning more like a charcoal gasifier in this area like you have said before.
Tone, how wide should the veritical grate tubing spacing should be if I am using round tubing?
I did make a welding tip to get into tight places like yours.

A round tube will probably work well, but a rectangular tube is better. If you compare how the pieces behave on a grate made of round pipes and how they behave on a grate made of rectangular pipes, where the distance between them is in the shape of a “V”, look, this is how all grates for wood stoves are made. Rectangular tubes also have a much larger surface area and thus enable better heat transfer. I used 15mm x 30mm pipes, and the distance between them is 10mm (probably a good distance of 10-15mm)

I was thinking of the smooth transition and the acceleration of the gases into the point between the tubes then expanding rapidy. The narrow point is where the frequency changes to it highest and the velocity is at it highest point. Then into a low velocity and frequency area drop out zone a cooling effect.
I love testing theories out of what others have done before me.

Hey Bob, can you explain the difference between frequency an velocity?
