A couple days ago, a deer came by and ate the stems of my impatiens while pulling them up by the roots right in front of me! I planted them back and the next day, I found them pulled up again! I planted them back again. This is turning into an experiment where I find out how many times the impatiens root can be pulled up and munched on then planted again and live. 😄 Today the deer came back yet...

Thank You, Charlotte! Yes it's true. I have noticed over time that animals are like that with me. Maybe that is why.
How long do you have to e to let the firewood dry?? And when do you split the fire wood when is green or dry?
Best to split it when green. Curing time: For hardwood , 2 years or more is best . For softwood, 1 year or more. The thinner the pieces you split it into, the faster it will be ready. Best of luck!
That ain't elm
Good job Sir.
Thank you sir! =)
Good work! th-cam.com/video/jh37t8H1g68/w-d-xo.html
Speak up, Mr.! Can barely hear ya!
What saying so true but sounds hard hear. I just split in circle wedge don't work in elm. I also don't use triangle mull just ax tyle.

I cut elm 2" long then it's easy. Try sweet gum it's hard to bust.
How long again? =) I haven't tried sweet gum.
love the hammer! Love your stuff! Love you!
Wow! Thank you so much!
Lovely work mate, keep it up
Thank you very much! I have some new stuff in the works too
To all the ney sayers, that was an American Elm. And this man is onto the right method. Although on his first slab he was too close to the center of the heart. Elm does not like to bust through the center of the heart like more traditional firewood’s are busted. It’s better to use a slabbing method similar to what this man is demonstrating.
I cut an elm last year. It is about 20in wide. I am using the 8lb maul from fiskars. It is like trying to split a sponge. The maul penetrates about half inch and when I pull it out the gap closes back up I can hit it 20 times in the same spot, no difference. I even pounded an ax along the grain and then bashed it over and over with the maul driving it as deep as the ax can go. Still wont crack. It is stuck in there. I am going to pound a wedge in along the grain along the same line. I think I will need to chain saw this ax out.
I had one last year that I had 4 wedges pounded all the way in and still didn’t split. That is until the chainsaw came out. When splitting Elm and some Maple by hand, a technique called slabbing it off will work better. Rather than trying to split the wood straight across the heart. Try about 2” in from the outside edge. Hand splitting Elm is going to be difficult, there’s no way to avoid that. But with a good technique and practice it will become a little easier.
Can't hear a word you are saying
I don't think that's elm. But if it is than whatever wood I'm splitting is ten times harder.
What you probably have is American Elm, which doesn’t split easily (standing dead for a couple years hardens them up and takes some of the stringiness out) What this guy is splitting is Red Elm, sometimes called Slippery Elm, which splits much easier.
I have to agree I have never in my life seen elm that straight before. Not saying it isn't elm, just saying that's a rare case if it is. I can say that those that are claiming that it's ash can't be correct. The bark is much to deep/coarse while being the wrong color for ash, and furthermore, ash wood is consistently light khaki color, not light sapwood and dark heartwood like the wood in the video. Most firewood burning dudes should know this since dead ash is everywhere due the the Emerald Ash Borer killing off the species, leaving dead, dense firewood behind. It's sad what's happening to ash trees. I cut and split cord after cord after cord of it, nearly constantly it seems because of all the people asking me to remove dead ash trees from their property. That way I don't really have to deal with elm, especially since ash puts off more heat (more BTUs per cord) and splits super easily. That said, elm is still good burning wood if you can split it. Although the distant microphone makes it hard to hear you, I love the acoustics I get when you finally swing. The stack and shed make nice reverb and the microphone catches the impact sound well since it's closer to the wood than it is to you, especially since I had to crank up the volume to hear your voice. I use your technique often for any species if the diameter of the round is too big to split down the middle. I'm here to make firewood, not to show off the ability to split down the middle, and I agree that your technique helps to make firewood efficiently, and yes, the resulting right angles helps in stacking. Thanks for posting your video.
I split my share of ash and all three variants (green,black, and white)are quite different.I find green stringy almost splitting like elm,Ash is my wood of choice for drying time.Off to brothers to split large elm taken down yuk yuk yuk putting it nicely.Bark looks like ash,are there a lot of ash bore bug marks under bark?
@@tjmax8203 Ash doesn't necessarily dry faster than other woods, but it seems like it does, because it often dies slowly and dries while still standing either partially live or dead. That way, it might be mostly seasoned the day you cut it, just because of how the dying happens with the emerald ash borer.
That's not elm it's ash it looks simular! The elm that grows here in western pa you ain't never going to split with a maul lmao! You need a hydrolic splitter and a hatchet it is so fkning stringy
That is 100% American Elm.
Thats not elm. Ive never seen elm that will split that easily
That is not like any Elm I have ever split.. Even a hydraulic splitter has serious trouble normally. Every Elm I have ever split is a twisted stringy mess. and if there is a knot, fogetaboudit! If you cut it down even if it was dead it's loaded with water. In my experience in PA. I watched your video today and tried splitting 2 clean logs that were 20 inches wide with my Maul and wedges.. I'm a strong guy.. I gave up after 2 logs. The stringy-ness was eating my lunch. The Ash was a piece of cake.. so was the Cherry.
Red oak is very easy!
strength isnt as critical as technique.. im 130 lbs and split the knittiest twistest Elm ever with a maul by hand.
@@bassmania84 Then you are a magician. Love to see you do it.
Very nice keep it up good workout
dont know what that wood is but the elm i have is so twisted even a hydraulic splitter has problems
all the american elm I have dealt with it stringy as hell and is easily recognized with it's horrendous smell for which it gets the nickname of piss elm this stuff does not look like american elm but I know there is more then one species of elm as well
no fiskars could ever do that. it took me 2 weeks to split a load of elm from a tree we cut down, where oak or locust would have been a single afternoon job. the worst I've found to split was mountain mahogany. ho......lee...........shit that stuff weighs twice what oak does and straight pieces simply do not exist. but it'll burn for damn near 48 hours in a good catalytic or airtight. it's BTU density is almost identical to anthracite
That's the truth ! When I hear about mahogany , it makes me want to build a sawmill , though . :) That must have taken at least 1.5 x as much time to cure before ready.
Least twisted piece of elm ever
That's not a maul. That's Thors hammer! LOL Nicely Done!
Haha Thank you ! And to think I managed to knock the head off a few weeks ago ! Oddly , the blow landed with the head not on the handle but the head came off and was just sitting there in the log and I was holding the handle in my hands . comical in a way. That will be for the next part in the splitting elm saga.
Some people do call it mull or triangle mull.
Needs a mike
Another thing to consider is where you want the air to go. The design that you criticized will probably push the air outward, and the one you gave will push the air inward. If you want more air to bypass the turbojet part of the turbofan engine, you probably want to push the air outwards. If you don't have enough air in the turbojet part, then we should use your design.
Thank you for your input! The intent of the shape would be to counteract the effect of centrifugal force on the air and convert it into linear movement . Looking back , I guess i might have made this vid more concise and and explain better. Experimentation will yield the answers.
Lol makes t look easy
Nice job letting the maul work and not letting it work you to death. Took me a while to figure that out.
Thank you ! Yes . Efficiency of movement . Funny thing is that method of swinging always felt natural to me .
Yes
Get a tire and avoid the back breaking lifting of those big boys!
You mean putting the log in a tire to keep them together during splitting ? It's a great idea .
Richard Montanaro Yes

how long did you wait from cutting the tree down till you split it? had it been drying long or was it freshly cut
I began to split the logs right away . That was one of the last ones . I split that about 2 months after the tree was cut down, however , it had been dead for about 4 to 6 months . Dutch elm disease . So I would say it had been dead around 6 to 8 months . So maybe a little dry but not much .
looks like a pretty wood is it similar to oak...I'm not real familiar with elm but looks like you could make alot of flooring out of it or something.
Elm flooring , that sounds interesting . You could have made not just the floors , but the whole house and a garage too out of this tree ! I kept only part of the trunk and part of a branch and I still have a year or 2 of firewood left . Actually, I just looked at the images on google of elm flooring and it looks really nice ! Nice grain . The thing about cutting wood into boards and using it like that is there is a drying process in a drying kiln that needs to take place in order to break the bond that water has with the cells in the wood grain . It's possible to just cut the wood and use it after drying in a dry place , but it is considered to be an inferior method . I was thinking about getting into this business at one time , but there are numerous others in the same business . I'm trying to do things no one else is doing . Who knows ? I may possibly do it still . I don't see anyone providing osage orange flooring !
I agree. Elm is the devil to split, but you sure do make it easy to split. How much does your maul weigh?
+Benjamin Evans Thank you ! It is a 12 lb maul . They don't seem to make mine anymore but this one is similar : www.amazon.com/Truper-32415-12-Pound-Splitting-27-Inch/dp/B000KL4V04 I found that the rubber grip on my maul tended to slide off when wet . I left it off to dry , then glued it on with industrial rubber cement later . no problems since . They hopefully have fixed this problem since when I got mine . Other than that , it has been a really good , effective maul .
Elm grows in a spiral. Every 6 inches down the trunk is a 1-2 inch twist. And when split literal wood ropes hang on for dear life and the pieces have to be pried and torn apart. This may be splitters elm. Ha ha. That is quite the maul.
Pipelyon Often they do . The heartwood on this one was like that in many places . The method still worked , but needed more work :D And the pieces were much easier to split if cut off shorter . I also used big wood wedges to split many of them apart after the initial split . I made them by splitting the log into small pieces and cutting them into wedges with the table saw , or just cut them with a chain saw , then painted them white or fluorescent green , so I could find them among the wood and sawdust . The sapwood tends to be easier to split , especially if the split line is tangential to the rings , in my experience . That tree was elm . Maybe that piece had a fortunate grain structure , but it was elm . The tree was elm , or it had elm leaves , elm bark , elm shape , elm seeds , but wasn't elm . There are a few elms on the property . Fewer since dutch elm disease has spread . That was what killed this one . Fortunately , the digger wasps ate the beetles . They should breed digger wasps to target the species of beetle responsible for the spread of the disease , imo . For that matter , do the same for the ash borer beetles , etc . I have split wood from another elm around here as well but that was before I figured out the method here . On that one , I gave in and borrowed a hydraulic splitter . This time , I just used a maul ! Anyway , thank you for the comment , and have a good one .
So many types of elm.... some spiral like crazy. Some split like butter
Good job, I will have to try your method. Thank You
LincolnSP150 Thank you !
Nice that you at least made it. In the late 70's (12 or 13), I built a model of a similar design (out of wood) that I copied off of a Popular Mechanics design for a manned glider. My model would of worked had it not been for the wrong type of wood I used. I always felt that soda cans could be incorporated into building one.
Thank you ! I have built small aircraft like this since I was about 10 . Less time these days , though . I plan to make a much larger and better one next time .
That's not elm.
Thank you for your comment but the wood came from a very familiar elm tree that was on the property .
That is english elm. The bark looks much different than a drake elm.
Excellent job! I ROFL'ed!
Thank you very much ! I'm glad you found it entertaining !
Beautiful.
A project of mine
I have a prediction for you : It will not be debunked . In fact , as the technology of blade construction advances, this shape will become commonplace in turbofans . As well I wish you the best of luck with your inventions !
A model would be a good (and probably more accesible (unless you live close to and have access to a good engineering school) than computer simulation) method to test this ideation. I wish you the best of luck, as I am a novice inventor myself and think it is awesome that you put this out on the web for people to comment and debunk. Most all the best inventions have come from someones garage!
In theory, wouldn't this design pull air towards the center, working against the centrifugal force? so instead of mitigating the effects of this radial force, your actually doing the exact opposite.. This may in turn increase the torque necessary to keep the fan at a constant speed. i am an engineer at Purdue U and can assume that there are a lot of highly intellectual people working at rolls royce running optimization simulations constantly and id be surprised if this wasn't already attempted.
But this is one idea for trying to mitigate the effects of centrifugal force imparted to the air caused by blades of greater chord . The simulations sound like a good idea . Maybe I will just build a model of it and test it out and see though .
Thank you for your thoughts ! I think that one of the things that makes it necessary for impellers/fans/compressors to have thin blades is that if they are too thick then the friction against the surface would cause a larger boundary layer to move in a circular motion thus effected by centrifugal force . The ring is an option but it need not be heavy imo especially if it made of carbon fiber and i think the main force acting upon the ring would be centrifugal force keeping it nice and circular
I am definitely not an expert in the field, but I would think your design would cause cavitation and/or extreme pressure changes (and in turn temp changes) due the anticipated air acceleration path. Your suggested ring on the outside causes a lot of additional weight, which means a lot more energy into rotating the system. Just something to think about. If you a serious about this, try designing it in CAD and running it through some fluid model simulations.
Thank you very much !
