Some more tractors.
Thanks for the pictures
Some more tractors.
Sorry for this post, but I was very impressed when I saw it online,… it’s a historical recording that would fit into this topic,… 
Love the cross with a marker over the gasfilling lid 
It’s electrical insulation tape (eltejp) 
Oh, so it’s blue because it’s gas neutral then 
Someone, i don’t remember, told me the correct color code in Volvo terms was: kalsongblå 
That made me laugh quite a bit. Am still laughing as I write 
That’s very good videos Tone. I wonder who that is. I’ve never seen him before. Besides Kristijan and Jakob, that has to be our youngest woodgasser 
obviously it is dr. göran…20 years ago…less hair in the face and another hat…
This 20-year-old video, as well as these pictures of tractors that you publish here, confirms the thought that my brother Pavel expressed some time ago, “that youth passes away, but beauty remains”.
For a time in the near past the joke was that only red vehicles made good woodgasing rigs.
Dutch John started this joke having his red brick Volvo and then seeing WayneK’s red Fords then a red Dodge Dakota perform.
Recall now W.K. had his wife paint over his Dodge full size V10 to a sky-blueish . . .
So. . .
(again a joke. laughing is so much better than silent frustertions)
The 20 year ago young man could have benefited greatly by not being such a No-Outside-Fuel Purist; and just using a gas torch to his lighting up port. Three times it took him, paper lighting! Video drama for sure. The sucking in sound clearly heard. The woosh-wump, sucking-in and you saw it disappeared. Magic, illusion. Great show.
Good operations are visually smooth and a bit boring for an outsider to watch. With only the experienced knowing the true skills needed to master to make it appear so.
S.U.
The thing that amazes me were that most of this stuff was made before electric welding was available at least to the average person. Getting air tight seals must have been a bitch.
A lot of oxy/acetylene welding on this gasifiers, the good welders made it look as good as todays tig welding.
Heavier parts mostly stick welding, replacement of the whole heart was a standard service procedure that mostly was stick-welded 
Fun you noticed that stuff, spot on as always mr SteveU
The Whoosh-thump, was often commented by by-standers, my mother still talks about that “funny ignition procedure” i learned along to get it right by rolling a perfect “funnel” out of paper, and to use the perfect newspaper, not shiny, dry paper. My experiments with torches newer worked good, the cheap propane torches i could afford just went out, as soon in put them near the draft of the air intake, and with the fan off they didn’t reach the char, like an air-cushion inside.
And: for the “no outside fuel” comment i Always!, recomend everyone curious about woodgas vehicles to build from the beginning a proper way to use gasoline, the first years with this Volvo i only had a carb in a box in trunk, to shift for the gas-mixer in emergency situations, talk about learning the hard way, its VERY embarrassing to push your woodgas vehicle to the side of the road, all by yourself, just because some bridging trouble or like.
To not talk about a stop in city-driving, just after take-off from a red light, pushing the car to the other side of a crossing, people honking, just because of a condensate pocket quenching the engine 
Sorry Giorgio for “hi-jacking” your tractor thread
