Woodrunner tractor

So, i haven’t forgot my Fergie, i see it everyday, and know it wants to try woodgas.
So, i ordered stainless steel mesh a while ago, this stuff has got much cheaper, and i like the filters.



A long package arrived today :smiley:

200mesh like in the Chevrolet.
Now to start collecting stuff for the filter, i really want to build it from stainless, because i dont use the tractor all the time.

Do you have a link to where you buy the cloth?

Hi Jan, i couldn’t figure out how to fix that link stuff, but maybe this helps until wife helps me.

Thanks Göran, it’s quite easy to make holes in the fiberglass fabric, so stainless steel is probably fine.

Hi Jan, yes it seems to work fine to me, a little soot could be found up front in water catcher, but very little, the condensate looks so clear i would’nt hesitate drink it, but it’s probably caustic so no good idea. The stainless mesh is a little sensitive to wear, but with a proper filter construction it’s no problem.

That sounds good, Göran, how did you make the water trap in front of the intake?

It’s just a tank with inlet and outlet on top, the inlet protrudes about 100mm the gas changes direction in the tank and throws the water to the bottom.

Picked up these empty propane tanks today


Going to build the filter housing out of one of them.

Some progress today.


First get the valve off, by hard, sharp knocks with a hammer (axe).

Then some safety precautions, filling up with water, it’s really impressive how a plasma torch could cut the metal with water on the other side.

No explosions, what a waste i used earplugs…

This is going to become the inner part of filter housing, this stainless piece started it’s life as a “hair strainer” at a public pool. :face_vomiting:
Now i need some gas for the welder, and fast!

Filter housing coming together.



Inlet pipe.

Inside.

Inner piece welded in, there is no “plan” behind the inner part sticking up, it’s just a matter of available material.

From top.

Some more done.


I picked up a nice gas cooler in my “gasifier scrap-yard”



A flange will do as clean-out port. An old explosion relief valve from a diesel heater became the lid.
Just to make a cast-in-place gasket from rtv.

Double inlet pipes to filter.

Update, some done today, until rain interrupted, and forced me to sit down horizontally on the couch.


“Y” pipe for the 2 gas pipes.

Filter in place.

Filter housing just “hooked up” in lower mounting, locked in place with only one nut in the top, makes it easy to lift it off to reach engine.

One gas feed pipe/metal hose in place.

Some painting left.

You’re a fast builder btw.

Hi JO, yes Ford it is, back in the time there was a Swedish Ford factory in Stockholms Frihamn, Swedish owned, under Fords name/license, as most Ford trucks was imported as a frame with engine, the rest was Swedish made, earlier, when cars had a lot of wood in the bodywork, this was the same, built local.
The rest was most “putting together” put on wheels, and other stuff, then away to the Ford agents around Sweden.
So, when war time, new cars must have a gasifier, as GM also had a Swedish plant, and was “concessioner” for Svedlunds gasifiers, Ford had to sell/mount other makes, in this case, wood gasifiers was bought in from Bolinders (Fords competitor in the tractor market).
This gasifier, marked Ford, system Bolinder’s, has been used on a tractor, probably Fordson, but had the Ford logotype on the gas cooler, which indicates it was meant to be put on a Ford tractor, like 8n?

You see? One of my boring history lessons again :smiley:

Rain stopped, and some nice evening sun, i chunked up some dry stuff for this weeks driving.

And did some work on the tractor.


Measured and in place both gas feed lines, with my “patented” seal.
Also made gasket for the clean out lid.
And some measuring for the cooler and condensate tanks.

Curious, what kind of hose do you have, and do you sell the sealant you have a patent on?

Hi Jan, here’s the recipe for my “patented” seal:




The silicone don’t withstand the temperature here, but the aluminum tape, and binding wire keeps it in place, as a hard crust.

The hose is thin stainless steel corrugated, from a local factory that makes this stuff for among all: nuclear power plants (!) This didn’t pass the super hard quality control, and ended up on a local scrap-yard, i cut of the end flanges, i believe the quality is good enough for me. :smiley:
