[Stoves] Important fuel processing Re: Repetitive Cross-Cuts.

[psanders at ilstu.edu]

Dear Andy, Andrew, Alex, Crispin, all Stovers, and of interest to  
Gasification folks also.

Wonderful device!!   see it at:

Different, and more simple than the choppers I saw with Ed Burton and  
Phil Jorgensen in Willets, northern California.  They use hydrolyics  
and can stop and reverse the cutter if needed.  Are there other  
options that need to be also recognized.

I want one.  Andy, we need to talk.   (on Skype at   paultlud    or phone
309-452-7072   or email )  Did you build this yourself?

Looks to me like no teeth.  It is a shear.  the cutting blades are  
tapered so only a small amount of wood is cut in each cm of the  
rotation.

Safety features are lacking, but that is not the topic here.  The  
topic  is that it works for chunking of wood.  Engineering will add  
the safety shields, etc.

Size of chunks is not the issue either.  Clearly can be scaled.  This  
unit is powered by a power take-off (PTO).  You can see it spinning.   
Geared down to the right speed.  So it can be geared to almost any  
speed and torque needed.

Also, the fuel could be in a trough at maybe 45 degrees from vertical,  
and come sliding down and hit a stopper to give the desired length.   
And possibly fed from two sides.

And the woody biomass could even be of brush-type and the crosscuts  
would give many short pieces with each slice.

For power source, I had a plan for using the power wheel of a regular  
car/vehicle.  Kevin and I talked about this many years ago.  The power  
part is fine, but I did not have the shear like Andy has.  Simple to  
combine the two concepts.

Also as a power source for a SMALLER unit for smaller pieces, this  
shear concept could be built to run from the power of a junk rotary  
lawnmower.  I have wanted such a device for years, and now the missing  
component is quite evident.  (Too bad my wife threw away a couple  
months ago the junk lawnmower that I was saving for just such an  
opportunity.  Now I need to find another one with the right features  
to make transition easy.)

My partner in Chip Energy (Paul Wever, who Andy knows) could make such  
devices easily.  And so could Crispin in the Swaziland factory or  
wherever he gets his hands on the tools.

Recent conversations about bamboo as fuel hit a snag about cross-cuts.  
  Now that is no longer an issue.

Okay, how do we proceed to accomplish the availability of this  
cross-cut technology to people who could well use it?  This is for  
both the affluent countries and the developing societies!!

Neat.

I kept trying to count your fingers but lost track every time my eyes  
closed :)

Hi Andrew,

Good to see you here! I have been wanting to read Stoves for a long time.
Doc T-LUD Anderson inspired me recently to join the list.

A polished brass T-LUD installed down below with a proper charley noble,
could
extend the short yachting season here in the chilly Great Lakes.
Diesel stoves smell horrible!

Two kw/ hr of heat to make coffee, and melt the frost from one's beard,
would require about two pounds of cherry pits.
This would be perfect for a certain antique H-28 I sail. The boat:

The cost of pits at retail-outlets is high, because packers use propane
to dry them.
So for many, chopping wood is the best option to fuel a gasifying-stove.
Here is the method I use to cross cut maple blocks:

Give my regards to Ken, next time you talk.
