OK, pine and birch? do you take spruce too?

I burn any wood but I avoid too much pine and spruce because of tar content. Also, spruce limbs are a lot of work to clean up before chunking.

Ha, Jo, last time I gassed only the wood chips from the spruce branches, the gas was terribly strong but the next day I had to heat the intake manifold to release the valves, despite the âgood gasifierâ the tar crept up.

Hmm we done have much spruce here untill you get above 2500â elevation and then it is most white fir (piss for we call it) and both of those are usually heavy with pitch like our lower land Doug fir. Guess I have been lucky so far to not make tar. Still have not seen any out of the hopper tank yet and near 2200 miles on the truck

Our miss-named âDouglas Firâ is actually a spruce variant.
No matter. They are all mostly pitchy.
And we still must learn to use in a wood gasifier.
Just as others here USA have had to learn to use Oak wood, their area pre-dominant species. Corrosive effects or not. Why they made stainless steels.
Out of your own woodlot cutting pitchy conifers in slow-growth winter helps some. Much less sap then.
The sap, and later water removed pitch, are chained hydrocarbons. The gasifier is an air/oxygen restricted environment. The exact opposite you need for full hydrocarbons chains de-construction conversions.
Conifer wood fueled systems tend to be very sooty. So you design for this.
But low, low ash. And that ash seems to not slag until much hotter.
So you better woods folks get to fight lower system ash clogging a conifer fed system never sees.
Ha! Ever paid attention to all of the sootâs flushed out of WayneKâs systems?
He uses some Pine wood. He had to evolve design to handle a lot of sootâs collection.
And he had to evolve his core choke plate sizing and shut-down procedures to stop having throttle plate binding tars.
Just my experiences and observations.
Knock the myth belief in an All-Gasifier out of your thinking is what helps.

Iâve been lucky enough not get any valves stuck yet. However, Iâm still suffering from my initial mishap with the Volvo. The cooler still has a sticky coating inside which makes it hard to clean out the soot later on. Less cooling ability doesnât matter much with the temps weâre having during winter, but I will have to do something about it before spring.

I saw one of the Swedish guys had a bubble can, to clean the intake.
It was a can of ethanol (I think) that sat under the hood with a hose to the intake that brought vapors from the can, if it does any good I do not know.

I got in touch with Remet, they said they can and will ship overseas to United States. I asked the price on the m100 class mechanism and he quoted me for 710USD for a 4 blade per axle unit not including shipping. The R100 is 1200USD. I believe the R100 is the full unit minus conveyor. The 6 blade M100 is only 800 dollars and will cut the pieces shorter.
I will heavily consider buying one. My diesel stationary may finally have something to power!

Ha! Ha! He used a whole tractor rear end assembly! Put those lawn ornaments to working!
His vehicle under-hood snazzy carburetor/woodgas mixer is on a different video on Makko Vâs youtube channel.

We got a chunker to make use of the smaller branch-wood around the farm. Makes great charcoal Red Dragon branch logger in action - YouTube

Here is a âsemiâ rebak one. It uses one of the wheels and an anvil. It is belt driven, and roller feeders. He was super safety conscious when he built it probably because of his kids. And while it doesnât work as fast as a rebak, it isnât terribly bad.

If you had a big stack of log slices,then you could make a press with rite size hatchets all in one press might safe some time makeing chunks.
Ha! Ha! We/I tried that Kevin in the VictoryGasWorks shop.
It works some alright. Right until you hit a wood pie round with knots in it. Jams up your head unable to full stroke. Leaves chunks jammed in the head to have to individually picked out.
And I was the one made up the 500 pound of sawn tree trunk pie rounds.
Seeing the saw/chain/fuel&lube wears and costs of that I only did it one time. All of those 2" cuts Iâd made for the less than 1/4 cord of wood-pie-rounds I could have bucked-up three full whole cords of 18" lengths firewood!
Anyone else wanting to try this . . . good luck.

that would be a lot of wear and tear on a chainsaw for sure, fuel and bar oil cost alone would be a little painful

Yeah I tried a 4 way head on my splitter. Jammed up as it expanded the quarters. I just have a blade now, smooth sailing.

The only thing to do is burn the pieces in a fire ring and make charcoal. Nice and warm around the fire at night with friends. That is what I do with that kind of wood, but mine is hard cherry.

What others said, Kevin.
I welded a 12-way wedge for my splitter a couple years back. Worked ok with knot free slices, but sawing those slices is way too time consuming. Gathering limbs or young growth for my rebak is a lot faster for gasifier fuel.

I see Laimet changed the video and the machine. I made a version of a helical screw chipper a decade ago after watching their video on line.
I started trying to set up my universal mill to machine a helix but I lacked too many components. So instead I spend weeks machining a screw with a 1" pitch from solid bar. I wanted a coarser pitch screw but that was the coarsest pitch any of my lathes would turn. I built the machine and then hooked it up to my 30hp tractor 540rpm PTO. Results were very disappointing. The tractor would stall feeding 1"x1" hardwood edges from boards into it. I fitted a diesel truck manual transmission to the machine. 1st gear provided a 4:1 reduction. Results were still very disappointing. The tractor engine would stall if feeding a 1x1 1/2" board.
I needed more power. A lot more power. Here I am - being forced to scrap diesel trucks I could use to power the darn thing

Cutting wood is a demanding task, especially cutting hard wood, the cutting knife must be made of high-quality steel to keep it sharp, and the wood must have space so that it does not get jammed between the blades and the housing, but that it can split along the grain,⌠can you post a picture of your chopper, maybe a video.
