Red Beard’s Garage just made a video for the big brother, the 459cc Max Performance. It’s a hemispherical head! Very interesting. I’ve noticed between the 212cc engines, the Hemi did have a hair more grunt than the Non Hemi.

Cody,
Mike LaRosa, Dutch John and I think Tom Collins, and a few others all use household all metal vacuums.
Kirby’s you just drop off the front belt driven brush head and wheels assembly. Flat metal surface then to holes drill and tap to mount a flange coupler to.
The Standard vacuum the whole motor and turbine fan pull off of the back with just four screws.

Sounds easy enough. I think the hard part will be to find one. Thrift Store Hipsters snatching up all the “vintage kitchy lifestyle items”. I’m not averse to using an inverter to power a blower, especially if it cuts my warmup time down. If I can’t find a good Kirby I’ll get some metal duct blowers that have a CFM similar to my engine at idle.

Nope. Much more flow that engine warmed up idle if you want fast gasifier heating up.
Think like irritating, can-be-dangerous old carbureted (Fords especially) 3-4 stepping down cold engine speeds. 1800-2000 → 1200-1500 → 800-1000 rpm flows.

More summer pictures…
It’s probably 37F but snowing fiercely. Several inches since 9am.
Good day to burn brush. I don’t have any, so will spend an hour cleaning the shop, and a different hour cleaning the electronic work shop.

Comparing the two tall ammo cans I have. New 120mm in the back, is much taller, and wider, but not as long.

The older 81mm can is shorter in height, less wide, but is longer.

The 120mm can I got from Sgt Troy on eBay, it’s in very good condition and to quote Steve1989mreinfo when I opened the can I heard a “nice hiss” of air rushing into the can.

The 120mm can would make both an awesome filter box post cool gas, or make a cheap and dirty no weld charcoal gasifier. Lots of volume.

Also I think if you used floor flanges, one could utilize pool filters with either one of these boxes. Would look like a science project but you could have a string of filters exiting one side and make a header of PVC routing to the plumbing going to the engine.

Especially with these ammo box sawdust filters I can’t see any reason not to just made drop in bags with the sawdust and then just change them out even daily if used that often. Clean the old bags and refill. Never a mess or dirty filter.

That does sound like a good idea Tom. But may be haveing the sawdust in a bag could a cause the gases to short cut between the bag and the ammo box walls. Keeping the fine sawdust in contact with the walls would be better I think the gases would percolate through the sawdust more.
It would be a snap to change out with top and bottom ammo hatch doors. Open clean out close bottom door refill, close top ammo hatch door you are done. You might have your refills in a bag ready to go, just dump the sawdust into the ammo box. I like that Idea for having you new filter medium ready to go. You carry some extras with no mess. That is smart idea and handy for a quick change out.

I think the bag could be packed tight against the walls Bob but if not then point taken. I recall Gary Gilmore’s filter with the gamma lid bucket. Dropping maybe a five gallon paint strainer bag in one and filling that with sawdust could also be tried. If anyone wanted to try the ammo box idea then I can tell you that the bags could be made out of mosquito netting and glued together with fabric glue. I have glued that material before with good result.

Any bag packed into a box you have now the bottom surface area to filter through. When it plugs up it will move up the sides of the box. With free moving surface area no plugging up can happen because it is moving around and free. Your bag idea is great for a quick change out of the filter medium.

Fellas consider reversing your gas flow to from the inside of the bagged sawn-dust to outwards.
Like a bag type household vacuum cleaner.
TomH’s mosquito netting mesh bag filled with sawn-dust with the bag neck formed and then clamped around a gas inlet tube.
All of that within the ammo can, barrel, whatever, with the bag form smaller and then the filtered gas collected off of the interior walls spaces.
This all sucked through of course.

I’ve never done this.
And am still too busy family’s moving down to three of four houses to rob for the time.

Great idea Steve way to go. Clean out is as easy as taking out the garbage. I really like this. When you get home from a trip dump your dirty bags out, wash them up and refill them with fresh sawdust.
You could use a simple tube with extra holes drilled in it . Yup this will work for sure.

Vertical hanging down would be best I think BobMac.
Would insure better, equal space around the bag.
And then if a small barrel or bucket used then the bag would lift up and out with the top removal.

Yes just what I was thinking and a snap ring bucket is a lot cheaper if not free.
Put a screen in the bottom with a 2 inch space pipe out the side.

It would have been good if someone would have started a filter thread way back when so that it would be easy to find. No one is ever going to go back and think about filters in this thread. Anyway I just wanted to mention that in the low heat enviroments we are discussing that saw dust would work in I think one simple filter media would just be shop vac filters. I know it has been kicked around a lot of times but having just cleaned out my stove flue and passages it occurs to me that the vac I use for that has had the same filter on for years now and when I do the cleanups I end up with gallons of soot and creosote. The filters keep screening through the whole process and then I just bang them against something and they are ready to reuse. I know they are a little pricey for what they are. I have a foam sleeve that also goes over them but never use it. It would be good in further filtering. So same idea. A pipe out of a container, ammo box, bucket, ect, with the filter fitted over it and simply swapped out every few days.

Ironically the ‘diy shop vac filter’ is a paper towel because holy cow, the filters are about half the price of the vac itself. My $3 used shopvac needs a new filters, and it was going to be 20 bucks for the complete set. (it wasn’t worth more then 3 dollars because it was previously used for drywall…but it blows up air mattresses well.)

If you want to use a ‘bag’ filter, I would lean towards a flat cereal box style, and then something to ‘frame’ it like u-channel to hold it in place and to keep air from going around it. plus the bag itself could be fold over construction because you aren’t worrying as much about the last inch around the edges.
