Capstan and tackle block demonstration

- We wanted to make a quick video showing how to set up a lifting shear and use it along with our tackle blocks and capstan. This is just a small test lift, nothing too heavy, I believe this stone weighed only a few hundred lbs, just something to get the drift of how it all goes together as many have asked. The same set up we used to lift a few tons for our cabin raising, which will be out soon.

Well I have spent the last few days watching all your videos. I find them amazing how much information I have been learning. You and your wife are so inspiring in this day and age. I wish I could be there, but at 58 years old and retired I'm not sure. Your work is so fantastic, you two should be very proud. I wish more young people like you could take pride in good old hard work with just your hands and back. Looking forward to seeing you two grow together in your future projects. Great job, Thanks for sharing your way of life.
There are two channels that I am glad for finding out; 1st is Primitive Technology guy and 2nd is your channel.
Thanks for the justification for keeping the old methods alive. I eschew power tools as a matter of choice. Thanks for the tips and exposing people to traditional ways.
I find all your videos inspiring and helpful. I know you served our country as a Marine but the capstan is a Navy tool. LOL. USN 67-71 Thank you for your service and for your videos. Teri
Thank you Mr. & Mrs. Chickadee. Another great video.... I subscribe to 398 channels here on youtube and you guys are my favorite. Your level of craftsmanship, your photography, and your editing are top notch. Your attention to detail puts you guys in a league all your own. Watching one of you vids is like watching the History Channel or a PBS special. Love it, love it, love it. Thanks for sharing!
Excellent demonstration! Loved every second of it. Great example of block and tackle with capstan.
Simply fantastic and unbelievably brilliant again. Thanks a lot for making, taping, editing, uploading and sharing.
That should work well for you lifting up the frames. My father build something along those lines years ago on the farm. He used to also to raise up pigs and moose as well. He was a shipwright and a carpenter. He did a lot of old school things that would impress quite a few folks nowadays that's for sure. You can also double triple and quadruple the blocks and tackles to increase the ability to lift loads as well. Its amazing what they did long ago. Archimedes perfected this kind of technology, creating the first block-and-tackle system using compound pulleys and cranes. This he demonstrated, according to one story, by moving a fully loaded ship single-handedly while remaining seated some distance away.
It’s so cool to see how well & how effectively such simple things can work!
impressive work. An art we don't see much of anymore. The rock raising reminded me of a roadrunner trap set by Wiley.
Great stuff Mr and Mrs Chickadee! I'm really enjoying your video's. Thank you.
I absolutely love watching your videos, they are very instructional and are just great to watch 👍
yes I find you videos so relaxing thank you keep them up
I would like to know more about the saw handles because I have two that need repaired or replaced that were my great grandfathers . This video has helped me to know how to restore them, thank you!
Looking forward to seeing the cabin raising very much!
I'm looking forward to seeing it all come together!
This channel is immensely underrated.
Awesome! Thank for the demo!
OMG, that's marvellous.
Just as a rough estimation based on the my guesses to the size of the lever and the spool on the capstan and the number of pulleys, this set up has roughly about a 120:1 mechanical advantage, not taking friction into account. That means that to lift that rock, which we'll say is about 250lbs, you only need to apply slightly more than 2lbs of force on the levers. Of course in reality, there's going to be losses to friction and my estimations will be off because I don't have any measurements and I suck at math
