Too much sawdust again
[Return to Topics]

now don't laugh - oh heck if ya must. Anyway, we have oodles of free sawdust piles growing around here, so i've been researching a good home for them. It seems most presto logs and chips are made from nuthin but sawdust, heated enough to melt the contained lignin, then they're formed under pressure and away we go. Now i don't know exactly how much heat or pressure, but we have kids to prove that never stopped me before.

So i already have a heated stock tank to warm things to boiling if i want to, and a 20,000 lb log splitter for pressure. I can neck it down for more.

Think i'll need more heat? I'm thinking the ideal hasta be somewhere under 400 degrees (or it would burn) but not at all sure. Reckon i could reach that with very little effort too, if need be.

Anybody ever make that kinda stuff? I'd kinda like to keep the whole experiment below the requirements for another mushroom cloud? This place can only hold so many divots. :)

451* is flashpoint of paper, ain't sure about

i'm thinkin.........    Posted 03-20-2004 at 10:29:44       [Reply]  [Send Email]
just jokin, i am sure you will figure it out.

thinks I'm crazy. But, I think you need to look to higher math for answers to your questions. For, it sounds to me like it has to do with physics. In that, you're dealing with "Fusion" to get "Fission". The objective is to fuse the sawdust particals together under pressure, And then defuse them by heat causing the whole thing to fiss like a roman candle. Er, er sumthin like that. .......uh uh what my initials?

Hmmm, well, I have wondered about making such things, fire logs and stuff out of the sawdust I have here. I do get rid of a lot of through horse stalls.
Anyway, the flash point of hardwwod is soemwhere around 450 degrees, I think. But, under pressure, that would likely drop considerably. You might give it an experimental try at the 200 degree mark. You would think that would be low enough to avoid any mushroom cloud effects, and from there you could see what it did and heat it up if necessary.I am very interested in your findings. My press is only a little 10,000 pounder, but as you say, things can get modified.
I am already getting a healthy market/outlet for next fall for the slats and flitches from the sawmill, and have a number of people, besides ourselves, interested in the sawdust for horse stalls.
I am going to do an experiment with some and see how it works as polishing medium in a tumbler, for brass.

well so far in my online diggings i've found that they heat pellets to 212 degrees f(Apparently they form them in roller presses and squash them 3/1) then cool them to 75 f for stability. Goody! With those kinda figures i can probly make logs. :)

Now let's see, i'll need a squashing chamber(probly well pipe) with a loose-fitting piston against a steel block on the wedge end (got one) -------- might as well burn a little to heat the rest to steaming ------- ya know, this might work! :)

Huh, 212? I am thinking a water jacket sort of thing, ya know? Maybe like the cooling coil coming out of a still? Wrap it around the forming chamber, going to and from a kettle of water sitting on a fire heated by burning sawdust, and wham! Push the lever to the splitter at the opportune moment....
I might have to try and make on as well, sell 'em along side the fire wood.......use 'em to light the furnace and fireplace.

well i'm sure the big kids use fancy stuff but i was thinking about making a wellpipe container with a hopper or something, set up a kinda double-boiler outa a 35-gallon barrel inside an oil drum, when everything warms up, swing the whole works onto the spltter and squash away. Now if a fella used a longer one, the off end could be bathed in cold water. That way they'd cool as the next one shoved them along. I'm sure it'd draw heat and stay warm once you started using it.

i meant pellets, not chips. :)
