DIY - Device for lifting heavy logs 

I don't even care what you're making but just watching you moving around after seeing you in the wheelchair is unbelievably awesome!!!!

As a teen, this is hecking awesome. If I get a hold on wood and tools I might-- no, WILL make something amazing.

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.

Ingenious. Needs some sort of ratchet brake to stop the load from dropping and spinning the handle out of control.

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.

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.

So great to see you up and about. Your creative mind is a treasure. Your enthusiasm is a joy to watch. Thanks Izzy.

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

love this type of stuff, Izzy. Keep it up. lots of folks benefit from your demos of basic mechanical systems.

I just built a log bucking station and the next step is a log lifting device so this is PERFECT timing. Thanks Izzy!

That’s great!! Can’t wait to see the finished product and the log cart. God Bless.

Love old smart technology. Cool build! Definitely do more of this kind of stuff!!! 🤙

So good to see you up and moving around!

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!

ok, that's pretty awesome. I've never heard of that kind of windlass before so neat seeing it in action.

Can't wait to see the finished product. I will be building it to go with your mill

Hope you are doing well. Always interesting builds.

Sweet workshop! Liking your videos.

Not sure how I haven't seen your videos before, but glad I have now. Ingenious!

Really interesting, can`t hardly wait

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.

Love that table saw gadget!

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.

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.

Izzy awesome as usual. Good to see your geniusness (not a real word)at work. Thanks for the great videos

Windlass? Beats being windless! Great build Izzy 😉👍

Love your inventions and solutions, Izzy. Awesome stuff

Excellent subject matter and delivery. More like this please.

LOVE THE VIDEO CANT WAIT TO SEE LOG CART

Your looking great, keep that brilliant mind working. Love watching your channel!

awesome!! I can't wait for you to finish this project!

Really awesome Izmaster! Love it. I,m building one tomorrow!

Mechanical advantage is a beautiful thing. Nice proof of concept!

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

Scott Clark 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!

Amazing, as always. You always amaze me.

Awesome!!!! I am glad you seem to be getting around real good these days.

Izzy Izzy so glad to see you making and moving sir.

Looking Forward to Continued Vids on This Project. Thanks! 👍

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.

Hey, that is an awesome project!

I couldn't help but chucked when you got the first version built and Brad comes in with the 400lb. log on a furniture dolly. Wait... WHAT???

Good to see you experimenting again learn lots.

Really clever design, exploiting slight differences in diameter to get huge amounts of mechanical advantage

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.

Genius! Nice work guys!

Interesting, Izzy. I've not seen this type of mechanism before. I know that a moveable pulley with one end of the rope fixed is a 2:1 mechanical advantage. Now you've piqued my interest and I'll have to further research the mechanical advantage of the Chinese system. Keep healing. It's good to see you moving around as well as you are these days. Bill

Great project/experiment! I like the humour that is increasing in this channel

You're a genius! Awesome videos always!

Wow very cool. I'd never heard of this chinese windlis. Very simple but amazing principle. Thanks for sharing this knowledge.

Cool idea! Great vid

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.

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!

I think that your brain is bigger than mine! Izzy love your videos and you never cease to amaze me.

Your machine flexed. Scary!!! ................................. I adore your other projects!

Very cool! Thanks for the physics lesson! I've never seen the Chinese version before, very interesting! Thanks for sharing, Izzy!

This is awesome and BRING ON THE POWER DRILL!!!!!!!

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.

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!

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.

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.

Awesome video!!!!👍👍👍👍

Sweet, your obviously on the right track.

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!

Cool stuff Izzy! 😃👍🏻👊🏻

Brilliant ! Something to play with thanks!!

Lookin good izzy!

looking forward to what you come up with.

That's pretty darn awesome good job guys

Besides Seeing up close of your eyes the music is my of my favorites today!!!😏

1. I love your shop. 2. The lack of safety equipment and using Brad as the potential victim of a violent hit on the head from the cranking arm on your lift is both exhilarating and hypnotic! The tension builds with every turn like a great horror movie. 3. The makeshift wood lathe using a fabricated box and your table saw is not only the scariest thing I’ve ever seen but also AWESOME!!! I’ve just subscribed to this channel and will be binge watching forever. 👍

Impresdive... looking forward to more!

Haven't been on for a while, glad to see you're doing so much better! As for your windlass, you can't beat a properly set up block & tackle system IMHO. Interesting though

That's SO KOOOOOOL!!!!!!!!!!!!!!!!!!! LOVE IT!!!!!!

That “lathe” sled is freaking awesome!

Cool idea and interesting video.

Looking good! Rob

Izzy, you're looking good man!

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.

Izz great video!

Izzy, you always amaze me. Carpenter with 40+ years of experience and love to see you in action. Thanks again.

The wood turning table saw gig is amazing

Love your videos, I always get inspired. The RU-vid channel smarter every day would tell you that you need a snatchblock and you will get lots if mechanical advantage.

Awesome ideas and particle application of those ideas I just started watching yesterday. So far amazing. 3/20/21

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.

That table saw lathe is way cool. Very impressive.

Fantastic!

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!

Block and tackle my friend, block and tackle. With the Chinese windless you effectively doubled your pull force with 2 lines pulling almost equal amounts. Double or triple that and each line shares the weight. Say the log is 400 pounds. As the Chinese windless is set each line lifts 200 pounds. 4 lines would be 100 pounds, 5 lines 80 pounds and so. It will slow down the lift speed but increases the efficiency. Another addition would be move the crank arm lower on the lift while the windless remains higher. Use a chain and gears from a bicycle and mount one gear on crank arm and one on the windless crank. Loop the chain and hoist away.

Super cool!

Hey brother, Looking good. You got it done but don't be lifting heavy things until that back heals. Unless you use this LOL.

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.

That’s crazy. Never seen that before.

Just add a flange on the side of the large diameter so it channels the rope to the correct location.

Great idea to share. I have been looking for a way to lift the logs I cut in my yard.

One word snatchblock! They are awesome.

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.

I agree you are looking great and healthy. would like an update on the spine issues

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!

It is great... really appreciated
