FWIW, I have thermostats. My shops spaces are very well insulated, so I keep some heat on all the time. The machine shop/utility room area also has a full bathroom so it can’t freeze up anyway. I keep that place at about 60 degrees F. But I run the woodshop about 50 degrees F.

Well we are coming onto a new year and I haven’t been in so long I have forgotten which door to go in. I am so concerned at all the moisture that collects on anything metal because of the propane heater. If I remember correct, wood heat takes moisture out of the air. So I am thinking of bitting the bullet and putting in wood heater.
I have made charcoal by putting holes along the bottom of a 55 gal drum, filling it with wood, and lighting it from the open top. You get a lot of smoke until ----- I put two pieces of rebar across the opening and set an open ended barrel on top of the first barrel, on the rebar. Then a good clean flame comes shooting out of the top of the second barrel. That clean flame is caused by the air entering the flame/smoke at the top of the lower barrel. This has all been discust before. OK I had a home made two 55 gal barrel furnace using those systems that are sold commercially. It worked great. After many days of burning, I had a 6" dia stove pipe in between the two barrels. It burned through, allowing air to be fed into the smoke/gas/flame passing from the bottom barrel to the top.
MY QUESTION (finally) Why didn’t the air leaking into the pipe between the barrels cause the smoke/gases to burn in the top barrel? Thus creating more heat in the top barrel like the air going between the two barrels at the rebar gap in the first situation? TomC
Hi, Tom!

Guessing: Too much, too unevenly and cold distributed air.

Good luck with your new build experiments. you could allways try the the dakota v8 318 or 360 rt.plenty of speed available, or just good old towing power on wood.

Hi @TomC
What is your seal for the ash door, I think I have a similar door as you, but find it difficult to know if it is tight?

Hi, Tom C.
I have quite a high temperature from my cyclone, (over 300c) and have thought about doing as Kristijan suggests and as JO has done.
Remove the cone at the bottom that holds the restriction and move everything down to the bottom of the fire tube, my question to you, what length of fire tube did you have when your car went so well, and what size of restriction did you have?

Hello Jan,
I took a couple of photos of my ash clean out, but could not get them from my camera to my new computer. Here is one of the outside.
Here is/are photos of my fire tube that ran so well. It is 10 inches in diameter and about 10 from the nozzle to the restriction. Don’t know what the diameter of the restriction was-- just a ring that I had laying around the shop. Maybe you can get an idea from the picture.

So you just mount yours on the bed instead of inside the bed? If I can’t build my charcoal unit on a rear rack for my Sierra I might just have to go for something like this.

Hello Cody,
Yes my gasifier sat right on the bed. At one point I found I was getting too much wind resistance with the stuff sticking above the cab. I think if you go back through my pictures you will see where I had to cut everything down to get them even with or below the height of the cab. TomC

Hi Tom, I like how you used barrel lids and made your cone inside the lower hopper to help guide the wood into the firetube.

Thanks Tom C.
I have a 12 “fire pipe and a little over 12”, between nozzles and grate, so it should work to do as you have done, would be interesting to try.

Jan; Can’t wait to see how it works out for you. The good news is with a 12 in. dia. firetube, you could put some “heat sink” panels around the tube like JO and still have a good 10 in. dia. working firetube. Even if you can’t get SS, just plain steel plates would work. And the 12 in. depth of your firetube is a plus–you can set you restriction even lower than I did. I would have liked to put my restriction at 11 or 12 inches. Now the bad news—I was working with 10 nozzles and it looks like you have only 5. If I recall, the holes were 3/8 in. with the nozzles removed which is how I ran it.
Got to see if I can find a program to convert your metics to inchs. Just looked back to see what you have and found your “walk around” video. You don’t have to appologize for your English—I found it to be GOOD. TomC.

Tom if you have a smart phone you can install free apps for conversions.
Also my laptop with windows 10 has conversion built in the calculator tool.

Yes, I’m a little worried that I only have 5, I can get tar in between these, the nozzles are 12mm (0.472 ") but I can drill them if I want.
Thank you for understanding my English, but is not very good, speaks far too rarely.
Try this if you want.

Jan; Now I have a question for you. I saw a Youtube in Swedishj (?) “Andra som Kor gengas del2 Jonas Hedenbersg Ford F150”. Does he say anywhere in there something about a “drizzler”? TomC

Hi Tom, I do not really know what a drizzler is, as I understand it is a gengas pot with an open lid, which is fed with chips a little at a time?
Jonas runs on chips but the system is closed, but he feeds the pot with chips a little at a time, he has a screw for it and a shock that pushes the chips into the pot, he also has a screw under the grate that take remow the charcoal and the ash that becomes below.
He has the same system on this car.

Thank you Jan; A DrizzilR is a gasifier that Mr. Luk Vanhauwert developed almost all on Youtube. He was developing it to heat a new house he is building. Along the way a cohort of his, used it to run an engine. I never thought I would see it actually be built into a vehicle. I think that Hedenberg is doing it. If this is a DrizzlR design, that arm is not really packing the woodchips into the fire tube, it is measuring the height of the chips in the firetube and when more chips are needed, the auger turns on and feeds more chips into the firetube. Thank you again for checking into this for me. TomC

I would like to go off subject and wish a Happy Birthday to our member DON MANNES! I say this to express my admiration for him. He doesn’t talk a lot about “theories”, he just jumps in and builds an example to prove or disprove a “theory”. There are talkers on here AND there are DOERS. I consider Don the biggest DOER on here. Congratulations Don. TomC
