The fact that you bring to life this simple knowledge, that would otherwise be lost to the majority, and present it in a concise to the point video is why I have always been a fan and why you have such a loyal following. Dave, you are second to none in presenting these golden nuggets of information. Thanks for doing this for all of us.
Dave love the idea. Monte is correct, if you were to suspend your load from the single pulley so one end of your rope is fixed and the other end you pull on you still get a 2 to 1 mechanical advantage. Still much easier to use 2 pulleys in overhead lifting. If using the setup horizontally, say to assist a stuck side by side, one pulley works fine as long as your load is attached to said pulley.
Finally a video of someone making a pulley. Thank you Dave. What if you're in a real situation without all the tools you've built? No auger. how could you get a hole through the wood? Ember? Pump Drill? Love the vids. Love "Dirty Rotten Survival" too. you should go on "Alone". I'm sure you could make it more than 55 days. Thanks again for the video.
I love your simple machines videos and would love for you to make a playlist of just those- flip flop winch, pulleys, the tripod "crane" thing... All common ancient knowledge that's all but forgotten. One more thing that would be good to teach would be a water still since chemicals are as much a concern in our time as biological contamination. Lovin' you brother, thankyou so much.
Dave, great vid on using the small froe. I'd like to see you craft a froe handle for a bushcraft knife blade which would allow you the fine control that the handle offers (froe in a pinch). Thanks and best wishes
The number of lines between the pulleys supporting the weight is your advantage. Also, you can use this other than vertical lifts. Add a block to each pulley for better stability. That's another carve, but simple.
I have always wanted to learn this. It would really help when hoisting a big deer for not only skinning but to get it up out of the way of large predators. As you know, Dave. We have bears in S. Ohio, (Adams Co.) is where our land is, and I've seen many tracks. Thanks for the awesome video.
Dave: You can always up an overhand slipknot (meaning to make a circle & pull a bight/loop/bend through it) to make the stopper part of the jam knot. That way, it doesn't jam up too tight to untie & you don't lose that bit of rope on the end.
since most wood grows wider growth rings on the south face (narrower on the north face), what is the best method to determine true center of a possible slightly elliptical piece to determine the location of the boring hole, in the field?
Another thing you can do with only one top pulley is to hang a series of smaller weights on the end you would pull, thereby reducing the amount of effort needed to lift the load. A series of small weights, rocks wrapped in rope for example, can be lifted individually, but have a big effect in aggregate!
The way you have it rigged, I believe you are multiplying the force four times. By the way I really enjoy your videos, and would like to see you attend one of the many Rokon get togethers held during the year.
Use a figure eight knot instead of an overhand knot for a jam knot. It is easier to untie. Dave you are calling an auger what I was taught is a brace and auger bit.
Give me a lever long enough and a place to stand and I will lift the world... then give me some pulleys and a rope and a place to tie them, and I will drag it anywhere you want ... The first is an actual quote, the second part simply belongs there ;)
People these days just don't know what you can do with wood. I run an implement on my tractor on a 24" wooden pulley that I made by laminating plywood... it runs a chipper that will eat 6 in trees... you can do almost anything with wood... if you try. :) A 24" pulley was way expensive... so I just built one out of standard scrap plywood. Been using it for years, just have to take it off and keep it in a building when not in use. It's not bush craft... but it's close. :)
You only need one pulley to double your pulling power. Attach one end of the rope to a fixed object, run the rope thru a pulley that is attached to the load, and the amount of force needed to pull the load will be cut in half. The trade off is the load will move half as fast.
+Monte Provolt I don't believe that is the case you cannot gain mechanical advantage with only 1 pulley you only reverse the direction of force applied-
upload.wikimedia.org/wikipedia/commons/e/e9/Four_pulleys.svg maybe could get away with out a second one but it will cause friction on rope through eye bolt for instance. but Dave is correct
+wildernessoutfitters if you attach the single pulley to the object you wish to move and fix one end of the rope towards the intended destination. Then run the rope through the pulley and pull toward your destination. You will travel twice what your payload travels, but will have to use half the force per distance unit. This would be for a horizontal pull. In the rig you set up, the top pulley is only redirecting the force, the bottom one is the one giving you the actual mechanical "advantage."
+Dennis G you are wrong Monte is right. Canterbury is also wrong. This is basic. two supporting ropes versus one. this is basic elementary school science.
+Monte Provolt I think I get what you are saying I am a slow study, but to make this happen you would have to be above the object being lifted, or moving it horizontal not vertical-
As an old woodworker who's used to working with power tools, I'm really enjoying this series. Thanks, Dave

great series Mr. canterbury, really enjoying this one
once again a very cool video, and so glad to have the daily Dave vids again.

I am loving all the information in these videos. Thank you for putting these together. I am I the only one trying every lesson on the weekend :).

now thats called back woods engineering, well done dave
Dave, we are gonna need some videos with that beautiful jeep, I can't stand just getting glimpses of it...PLEASE!
Thank you for making it so simple. I guess one doesn’t need a fancy Lathe to get the job done! Right on.

I'm lovin' this series !
Nice video - I really like the cat's paw knot.
Who would dislike this? Its just the sharing of general information. People need to get a life
Awesome project Dave. I'll put this project to my todo list.
Greetings from Germany

Thanks for making vids and for being very clear on the instructions I'v learned a lot from watching your channel. Thank you.
Good technology! Really enjoying this series...Thanks, Clark
Maybe we should also be talking about those sweet jeeps in the background, plenty of mechanical advantage there!
hey dave one question on the foot vise has the stick been flatten at all on the bottom ? thanks
great video as always dave!!
another addition to the kit would be some files, namely for this project, a round bastard file to make the rope groove here.

Anyone have a link to the blacksmith mentioned? The one who made the larger froe. Brad Holman (sp?).
Pulleys worked!! must of been a satisfying moment.
What supplies do I need
This was most satisfying to watch

like these programmes very educational . thank you sir:
if Your doing this in place run the pull rope through a eye bolt and put a prusic knot on the pull line to stop the pull line from dropping the load
Spot on big guy. I will be replacing my skinning rack with something like that...people won't know what to think!
Thanks buddy, old school definitely rules.
Use a figure eight knot instead of an overhand knot for a jam knot. It is easier to untie. Dave you are calling an auger what I was taught is a brace and auger bit.
are you planning to add a eggbeater drill and twist bits later on, it might come in handy
That was awesome. Thank you for the information.
Dave, could you show how to make a double pulley?
+Greyman Zink, longer pulley and more cut rings, loop the rope, the number of lines supporting the weight between the pulleys is your advantage.
love this , so simple yet so useful ! great stuff :)thank you
pulleys are sooo cool...thanks
Awsome sires thanks Dave.
Look how strong Dave is!..
thanks
Awesome 3-1 ma so 200lbs went to 66 lbs or so. Great vid
What kind of rope was that?
+Jeff Witt
not sure but it looked like maybe 1/2 inch natural hemp rope.mighta been bigger
Thanks. Good info as usual.
Great info. Thanks.

that's awesome

That's how they built the pyramids.
+Henry No, slaves with mammoths did. Haven't you seen 10.000 BC?
Dave, stop spitting!!! Grumble grumble!!!
