I don't even care what you're making but just watching you moving around after seeing you in the wheelchair is unbelievably awesome!!!!
thank you brother
This is the best youtube comment ever. Good work sir!!! I agree completly. Oh and the content of the video is cool too ;-)
Yes, both are uplifting
Absolutely.
@@izzyswan did not know you had been injured and were in a wheelchair for a while, glad to know you are doing better every day, only the best of luck in all things and never forget how amazing you are
So great to see you up and about. Your creative mind is a treasure. Your enthusiasm is a joy to watch. Thanks Izzy.
We love your projects , majority of us don’t possess your genius , skill , nor equipment , but we all can adapt and use a lot of your great ideas , my admiration to you sir.
As a teen, this is hecking awesome.
If I get a hold on wood and tools I might-- no, WILL make something amazing.
I just built a log bucking station and the next step is a log lifting device so this is PERFECT timing. Thanks Izzy!
Several years ago I did something similar, but far more crude. I took 2X6s and made a structure shaped a little like a child's swingset. I attached a come-along to the crossbeam, and used it to lift one end of oak logs onto the tailgate of my truck. i could release that end, and then use the come-along to lift the other end, then slide it into my truck. The biggest log I moved, I calculated to be about 600 pounds. It absolutely maxed out the capacity! But at least I could assemble it on the spot and do the whole task unassisted.
Great to see you up and about. As usually, you are awesome with wood and tools. Thank you for sharing. Also, much success with this project and everything you touch. You are an inspiration to us all.
Looking Forward to Continued Vids on This Project. Thanks! 👍
That’s great!! Can’t wait to see the finished product and the log cart. God Bless.
So good to see you up and moving around!
love this type of stuff, Izzy. Keep it up. lots of folks benefit from your demos of basic mechanical systems.
Here is a variation on your Chinese winch setup. Several years ago (80’s), I meet a pair of “Amish” loggers that had a similar setup but they had different sized spools their setup. The spools were wooden with centers that had a slot in them. The slot keyed the spools to a metal shaft that als had a slot. They said that they could pick full logs up to about 30” diameter to load in their wagons. They also had a smaller portable winch set up for pulling logs to get them were their horses could pull them. The reason I remember the set up was a clever toggle ratchet safety that was operated by moving a brass ball on a steel rod that allowed you to safely lift or lower the log.
Really interesting, can`t hardly wait
Ingenious. Needs some sort of ratchet brake to stop the load from dropping and spinning the handle out of control.
Came in to suggest this.
would try an escapement mechanism with the handle as the input. you could increase your moment and no longer need the step ladder
Love that table saw gadget!
Thanks for showing this! I think it really cool and unique way to mechanically solve for the lifting of the large weight. It reminds me of changing gear ratios to add more torque at a slower speed.
Ayup, Chinese windlass, still in use today. Mostly, as far as I know, in large roll up doors. Use the windlass to pull on an A frame hoist and it should improve your mechanical advantage.
Can't wait to see the finished product. I will be building it to go with your mill
looking forward to what you come up with.
Love old smart technology. Cool build! Definitely do more of this kind of stuff!!! 🤙
The old guy's way of doing it. A large pair of wooden wheels with an axle between them. A long lever/tow bar perhaps 20 or more feet long,,, the center pivot point only 3 feet or so from the center line of the axle for that lifting lever/tow bar. Log laying on the ground,, wheel your wheels over top such that the center of the log to be lifted is directly under the axle. Tilt the long handle, tow bar up,, attach the center of the log,, pull the long lever arm down,, which raises the log off the ground, wrap a chain or rope around the one end of the lever arm above the log, and now tow it to where ever you need it.
Sweet workshop! Liking your videos.
Mechanical advantage is a beautiful thing. Nice proof of concept!
Hope you are doing well. Always interesting builds.
Excellent subject matter and delivery. More like this please.
Izzy Izzy so glad to see you making and moving sir.
LOVE THE VIDEO CANT WAIT TO SEE LOG CART
I was thinking a vehicle winch using this principle and driven by a drill, but it then occurred to me that the amount of cable required would possibly make it impractical. Thanks Izzy - great ideas demonstrated!
HI Izzy! I'm impressed by the load few 2 x4 can stand! Can't wait to see how easy this system will lift big load with some improvements. Thanks and take care of your back!
awesome!! I can't wait for you to finish this project!
Love your inventions and solutions, Izzy. Awesome stuff
Brilliant ! Something to play with thanks!!
Fantastic!
Sweet, your obviously on the right track.
Amazing how creative you are using natural forces. I bet more kids would go into engineering if they had teachers like you, who could take a Statics and Dynamics text book and make it fun and useful. Thanks
Never saw this technic. I’ve always used several blocks until it feels easy enough.
I may throw something like this tiger to lift my mower and atvs is for blade changes and tire swaps etc...
Thanks for the video. You’ve help atleast one person (me) and that’s reason enough in my opinion!
Good to see you experimenting again learn lots.
ok, that's pretty awesome. I've never heard of that kind of windlass before so neat seeing it in action.
Amazing, as always. You always amaze me.
Genius! Nice work guys!
That's pretty cool
Cool idea! Great vid
Amazing concept. We can learn so much from the very clever geniuses of the past. One thing that I would change to control the rope is to put a trolley like pulley system instead of just a single pulley. That way when the rope comes down and then goes across it goes a farther distance before it goes back up on the way to the log will be held in between the two pulleys keeping the pulleys level to the ground.
Super cool!
Hey, that is an awesome project!
It is great... really appreciated
Izzy awesome as usual. Good to see your geniusness (not a real word)at work. Thanks for the great videos
Izzy, I love the Chinese windlass and I'm glad you are incorporating it in your lifting apparatus.
I also like the A-frame, and encourage you to consider incorporating that into the framework-both front-to-back and side-to-side. More resistance to racking and less material.
Looking good! Rob
I agree with someone that said "could you use a set of gears?" You could. Build a two speed gear box like they use for lifting trailer's on and off the big trucks and add some type of locking system to keep the load from wheeling back(safety first)down. Love this build! Looking good!
Not sure how I haven't seen your videos before, but glad I have now. Ingenious!
Ingenious! A typical "IZZY" performance, a totally different approach made somewhat practical. The mover will need some big tires, and the drill or a treadmill motor may be needed to tow it; but SCORE ONE for IZZY the CHAMP. And its fun to see you use the traditional approach then change it up to something more effective. Thanks again for the master class =Master Izzy!
Your looking great, keep that brilliant mind working. Love watching your channel!
Thank you Izzy. I have a big walnut log I need to haul to the sawmill. I should make your sawmill but I don’t do it often.
You're a genius! Awesome videos always!

11 hours ago, "I am interested to hear what the log weighed in at if you did actually put it on the scale later as you mentioned . I was going to guess it wasn't over 250-275 lbs but you know the camera adds 10 lbs they say . Cheers and looking good on your feet mister. ----- *_THOSE INTERESTED, READ BELOW_* ------
at 8:34 Izzy says 20-inch diam. and 4 feet long... SO. 20/2= 10-inch radius so Pi*r^2=3.141592*10*10=314.1592 square inches So times 48 inches long=15079.6416 cubic inches, then divided by 12 cubed = 8.72664 cubic feet total wood volume ... wood floats in water ... if just floats then 62.4 pounds per cubic foot for water so times 62.4 is 544.5426 pounds, but if the wood floats 5% out of the water then, 95% times 544.5426 = 517.315 pounds total weight. If a sample of the wood floated higher out of the water, you'd have proportionally less weight overall.
NICE CALCULATION, ISN'T IT. DIDN'T KNOW YOU(Talkin' to your readers) COULD CALCULATE LIKE THIS DID YA(Talkin' to your readers)? AND anyone can do it!!!
Science, Love it!
My Civil Engineering dad would have been proud of that calculation !!!
SOME FOLKS CLICKED ON "LIKE THIS" Glad you enjoyed this. Please DO CLICK on "Liked this" if you did. Thanks!
Really awesome Izmaster! Love it. I,m building one tomorrow!
This is awesome and BRING ON THE POWER DRILL!!!!!!!
Lookin good izzy!
Awesome video!!!!👍👍👍👍
This is great. I am looking forward to the completion. In the very near future I am going to have quite a few logs to move and a machine cannot get into the area.
Awesome!
That's SO KOOOOOOL!!!!!!!!!!!!!!!!!!! LOVE IT!!!!!!
THAT is v cool.
Will definitely use .
That's pretty darn awesome good job guys
Awesome!!!! I am glad you seem to be getting around real good these days.
Awesome! Respect!
Impresdive... looking forward to more!
Besides Seeing up close of your eyes the music is my of my favorites today!!!😏
I agree you are looking great and healthy.
would like an update on the spine issues
Cool stuff Izzy! 😃👍🏻👊🏻
I make a tripod from 2x4s with threaded rod through sloppy holes. set up over the load, clip a come-along to the rod,
and lift while standing on a ladder. Easy for one person, relatively safe, & the whole rig stores in a small duffle.
One word snatchblock! They are awesome.
Windlass? Beats being windless!
Great build Izzy 😉👍
Good job
Great video showing how to work smart but I think the best part was getting to see you up and on your feet working. Glad to see you on the move, be safe.
Wow very cool. I'd never heard of this chinese windlis. Very simple but amazing principle. Thanks for sharing this knowledge.
Hombre grande sea feliz con salud riqueza y fe saludos desde Nicaragua.
The wood turning table saw gig is amazing
Izz great video!
That’s crazy. Never seen that before.
Great project/experiment! I like the humour that is increasing in this channel
Can't wait to see what happens next. Back in the day I would muscle everything, now ....its levers, winches, pulleys and on and on ....and as they say, work smart not hard! Very intersted in seeing how this project progress since I want to do some milling and I will probably end up doing it by myself but limited due to back and neck injuries somewhat similar to you.
Thanks izzy!
Awesome 👍
That “lathe” sled is freaking awesome!
Thanks for the video. Love the concept. If you want more mechanical advantage, don't lift the log straight up. Use the Chinese Windlass to roll the log sideways up a ramp onto a trailer or truck. When doing this, you can ditch the pully. The rope goes around the log itself and helps roll it up the ramp. You park your trailer next to a large tree on the left. Meanwhile the ramp faces to the right. The windlass is tied to the tree on the left of the trailer and pulls the log sideways up the ramp. Hope that helps and made sense.
awesome video. I feel like I could use this as a gantry of sorts in my garage for light duty obviously. build it up by the ceiling and on the wall have a pulley on chain setup to come down the a handle or drill insert. nice video and I'm glad to see you're moving around so much better.
Pretty neat.
Thanks!
DO NOT FORGET: whichever type of windlass you choose the total weight of the log still bears on the one or two strands of rope. The rope has to be strong enough.
The Chinese windlass does indeed give tremendous mechanical advantage on the HANDLE. Do a little math and the force you apply to the handle of the crank is maybe one tenth of the first windlass. But the reduction of load on the two ropes is only half. Yes, I think he could lift a ton with that - IF the rope was rated for at least a half a ton. Any lesser rating and the rope would break.
Also, rope stretches as you pull it. When it snaps under tension, some types like nylon can whip around and cause nasty injuries if the end hits you.
Cool idea and interesting video.
That table saw lathe is way cool.
Very impressive.
I am thinking of building a variation of this in my forrest to deal with a cumbersome hanging tree over a path. I'd just attach the axis to a bunch of other trees. We tried something like that before, but didn't have the right set up and didn't really trust the rope and when something under that kind of tension breaks, it''s bad. So I am first gonna find me a sturdy piece of rope. And then build this puppy. This was brilliant, thanks!
I have some buddy's that do 18th century naval reenactment. They use a gin pole to lift cannon barrels . It is basically 3 long poles connected at the top. They use block and tackle from the cannon to the top and down to a pull rope. Just thinking out loud: You could affix a cross piece to two of the legs and attach the windlass there so that it is at a manageable height to work with...or even better, just attach an ATV winch to one of the legs.
Great idea to share. I have been looking for a way to lift the logs I cut in my yard.
Really clever design, exploiting slight differences in diameter to get huge amounts of mechanical advantage
Stumbled upon you. Won’t miss anymore. Thank You
Ok, I'm starting to regret finding 🙃 your channel. EVERYTIME I watch, I find something I have to build. I really like the device to create a giant dowel rod. Your talent is overwhelming
I see alot of applications for this in my cutting area. Looks good to me.
Too cool!
I like it
