Thank you, mr Wayne, but my hands looks only carbon black to me?

Thanks Marcus, yes, i believe a “mix” of rat rod and “mad max” would be the category this contraption fits in to? 
Anyway; i like both styles…

Cody and JO, thanks, about fuel economy, a very rough test i did yesterday, (sorry for the metric) i drove it 6 km, “full throttle” on a small, paved, “hilly” road, the consumption was a little less than a litre.
Wich would mean i should be able to run it around 10-12 km, on a full hopper.
The charcoal i used was mixed, much softwood, and pretty damp.

Thanks Steve, yes the small copper tube is for water drip, i didn’t use it in the video because i found out earlier when tinkering with the moped that the charcoal i used was damp enough, lots of condensation on the filling lid, and even some “gurgling” noise from the blower

Thank you Kristijan, yes what i was mumbling about was: i wanted to “prove” for the disbelivers that it actually run on charcoal-gas, by opening the lid, i had no idea what would happen with this particular gasifier, if it would slowly stall, or raise in rpm, also, charcoal is a new path for me, still learning 
Thanks for a great explanation of the “goings-on” in a charcoal gasifier

That was the coolest moped run ever. That surpised even me when you ipen the lid. Lots of Hydrogen burning. Okay now you can look for even a bigger bike to charcoal gasifiy. Great building and what everyone else is saying. Thanks again for the video.

No progress this weekend, feels like im having a flu, sore throat, no feeling for welding or grinding, and a terrible weather with lots of rain.
Anyhow, i did some further inspection on the hearth of the chevy gasifier, found this crack in the bottom of the air chamber.
It doesn’t look like heat-distortion/warping, my theory is i had somehow water standing in here that has frozen and expanded, i base that theory on that the truck was standing some 3-4 month’s during wintertime due to a broken rear axle, as i think about it, it has never run perfectly after that, often get very weak gas when over-pull/over-heat the gasifier which could be this crack open-up by heat expansion?
Just theories but seems possible.
Now for this “fun” part, stainless should be extremely clean from organic/carbon when welding to not “infect” the weld, yeah, good luck with that in a gasifier, i can take a little rust
I’ve mounted a battery for the blower on the moped, very “discreet” installation, really blend’s in
I planned to mount a smaller, motorcycle battery, but this was free, so… It’s the type lead battery that is mounted in many cars with start-stop function, as a electronics “memory” battery, these are changed out parallell with the standard battery, and these are often good enough.

i found on internet market place this grinder…the gear makes 24 : 1 …i will use for my next gasifier as hand blower gear…the model with 4 axles is the speediest, others have 3 axles, and are slower, but with a additional bicycle sprocket gear at the crank should also give high turns…

That is a very good idea Giorgio, i have saved a gearbox from a very old flexible shaft clipping machine (Chicago clipper, for horses and cow’s) i belive that should be a good gearbox for the same purpose.
Some of the war-time hand crank starter blowers had a gearing around 1:200, very heavy to get going but when up to speed you only have to “follow” the crank, much like the old cream separators.

Today i put an order on stainless steel fine mesh, of the type others have posted here, it should be really interesting to build a filter and try it out.
I’ve hesitated a long time about the “investment” but after some calculations i found out i actually payed more for the seven welding blankets i used for the filter, and i dont count the driving to get them, (had to visit four stores in the warehouse-chain, because they only had 1or2 on the shelf)
Now it’s time to come up with an idea for a “cage” to hold and spread the mesh, it going to be a star-shape as i had before.

Depending on how stiff the material is, you may be able to pleat it with staples and make it hold its own shape.
But yeah a cage might be a better idea, I guess it would also need to be Stainless.

That is what im in to also, but i believe a simple cage made of cheap stainless wire will do, anyway it’s needed to keep the mesh from get “sucked together” when engine breaths heavily, and the soot-cake starts to get thick.
The filter i used before i made a cage out of square net, like chicken-wire fence, that should be stainless, and looked like stainless, but was’nt, i believe that i was the culprit of my filter broke down, seems rust has “saturated”? the fabric, making it stiff and brittle, but this is just a theory.
Anyway, i should have checked that “stainless” net, that i bought cheap second hand, with a magnet, but even that can be misleading, cheaper ss qualities are often magnetic, ferrous stainless, especially 304- non acid-proof.

It was probably Galvanized. One way to figure out if it’s Galvanized versus Stainless is to hit the metal with an Acid, the Zinc will melt off. When I get zinc plated objects and want to remove the plating I’ll leave it in a tub of distilled vinegar.

Yes, i was aware of that, this just looked to “shiny” and no coating of the wire joints, (spot welded net, not like the twisted together type)
It probably was some higher quality galvanized, thinner, more shiny coating.
Thanks for the tip about vinegar, often when i restore old stuff i want bolts and nuts just un-threated, or rusty. Un-threated bolts are by some way more expensive, and harder to get than the zinc-plated or galvanized one, i have used hydrochloric acid before to get them bare-metal, but that stuff is impossible to get nowadays.

Just be prepared to wait a few hours and still brush it with a brass or steel brush with the Vinegar.

Yes, with vinegar it would be no problem let it stay overnight or more, and then give them a round on the old wire-wheel (that evil machine that uses to grab things you really need, and throw them under the workbench in a speed near the speed of light)
