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

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.

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.
