Thank you for showing the inner works. I've wanted to build one of these for a very long time, I'm glad I found your video. Get a couple of bicycle inner tubes and cut a long strip out of the center to get rid of the valve. That'll leave you with a long rubber band that you can cut the width to fit the pulleys.
Like An old clock with a weight, that's right. Thank you for sharing sir. I love these wooden kinetic things. There just fascinating to watch. Stay safe and healthy everyone out there ☮️
Thank you for sharing the explanation of physics behind the display where it takes away stress of the day while sitting alone or with family and friends.🧐😱
Thanks. Nice video. Old Singer Sewing machines use a leather belt that was a round leather cord and had the ends wired together like a staple through the leather and bent over. I think you can still purchase the round leather cord somewhere.
To help with the drive friction try tuning a deeper grove in the drive pulleys to allow for two {not one} large O rings. Neoprene or silicon work best. You will stop the slip problem.
Watching your video I am interested in learning this technique You asked about anything you could use for the pulley have you tried Elastic found in sewing departments in Walmarts it comes in all different width sizes and it might work
Very familiar with it! It doesnt hold quite enough tension on the pulleys to keep them from slipping! The winding spring is very strong! Takes a lot of pressure to keep it in place ! Thanks for watching!
@@dondale68 it does get addicting! I started it for another reason, but I got kind of obsessed with seeing how long I can make it run! Definitely a bit of finesse to it. Currently up to 45 minutes on this particular spring (which is not the correct type of spring for this application) but I had a few soooo. It works fair!
To give your belts more traction, look up something called grip tape. That stuff works wonders. You only have to use a little bit: quarter to half inch pieces every 90-120˚ on small wheels (though you might as well wrap the whole wheel if it's 2 inches or less) and about every 36-45˚ on larger wheels (about the size of a salad dish or larger).
Very nice, and wonderful, Thank you for your explination. Actually, l am trying to understand such spring drive mechanism for kinetic wall sculpture. But in your video, there some little mistake to focus the particular parts / mechanism. It is a fixed camera shoots which fixed upside. It is need some particular scene should be focuses. Ok. Thanks.
To get better grib on the wheels, wouldnt a rubber band that fit the wheel work? And then another rubber band that fit the two wheels it has to transfer energy between. Then its rubber on rubber.
maybe put a thin bead of silicone caulking on the wheels? just enough grip for the rope. alternatively stick spokes into the wheel to make gears and use a chain.
The spring you need constant torque spring but the ones I have are only meant to pulled in a straight line not counter torqued. If you can find a supplier of counter torque springs let me know! I’m looking also! Thanks for watching!
Hello, Shawn. I want to firstly congratulate you on this project. I really appreciate all the work you put into this, and all the attention to detail. I have a small question though. I found on Aliexpress the type of spring you used, but i could not find the exact specs that match yours. Could you provide a link where i could buy the exact spring you used in your project? Thanks in advance!
The springs that I used are actually the wrong type of spring for this application! These springs are actually used to provide tension and retraction on a straight pull they are not meant to be counter wound so they distort after only a few wined ups!
The belts should not bottom out in the spindle groove. Take a look at spindle profiles for like a drill press, the groove should wedge the belt to prevent slippage.
Bro, you just missed a step on your belts is all. Take these belts, rub them down with some rubber cement, squeeze all the extra cement back out, flattening the paracord as you go. allow to dry. You get a lot more grip, but not too much.

Thank you very much for this detailed rundown, it was very helpful to understand the ideas behind these mechanisms!
Great video. Glue pieces of the same timing belt on the pulley with the teeth facing out and no more slipping.
That really neat . Great camera angles and explaining things
Thanks and thanks for watching!

Great and informative video. I'm contemplating building a sculpture myself . Thanks !

Awesome video thanks for the time and effort spent making, very insightful!
lovely! i've been looking for someone explaining these mechanisms for beginners for awhile! thank you very much, great quality!
Wondering if you made bands from bicycle tire tubes
Wrap the belts round the pullys twice for slip resistant drive

Rosin, the sort used on violin or cello bows might give you the grip you want.
thank you so much for explaining the mechanism !!
Thank you so much for the explanation. Been driving me crazy for years. Hope you do provide plans. I would love to make this. Thanks
You are brilliant ! Great video. 👏👏👏
Bahaha “closet nerd” at best! “You are a legend!”

@@ShawnWithTheWildALONES7 sorry just trying to help a totally amazing piece loved it
Great I appreciate you for the detailed explanation, can you please suggest me were to buy the spring you have used in the sculpture. Thank you
They're called 'constant torque springs'. You can get them from Amazon (other suppliers are available XD).
To help the belt from slipping use a q tip to apply contact glue to pulley grove let dry works good.
I think David C Roy uses long thin springs. This way there is constant tension and most efficient
Definitely! still haven’t figured out where to find them tho!
Can I ask where you find the spring material to make the spring motor?
Have you tried round polyurethane belting. It's cut to length and melted back together, so it can be any length you want.
That seems to be the best answer! I haven’t tried it yet but I did order some, just waiting for it to come in! Thanks!
@@ShawnWithTheWildALONES7 Let us know how it turns out! I got the ''tick-tock'' addiction, now I'm looking at kinetics! I smell sawdust!!!!

line the insides of the wheels with 120 or 240 grit sand paper
Can we get the dimensions of the individual parts you have used?
You’re not the first to ask so I’ll try to draw that up this weekend!
@@ShawnWithTheWildALONES7 Thanks a lot
@@ShawnWithTheWildALONES7 Did you get it?
@@ShawnWithTheWildALONES7 I would also be interested. I've made a few wooden kinetic sculpures and would be willing to trade designs.
@@dh854-p2n I’m a little behind but it’s still on the to do list!

Perhaps to stop the string slipping, thinly line the grooves of the wheels with some silicone or use hot glue stick so as to create some traction
?

I have studied David Roy's sculptures for a long time. He does not use belts, they are very long springs.
Sir please explain tha technical Sid
Muy buena explicación , muchas gracias

Cool, where did you get the spring? Is it a constant torque spring?

あなたは素晴らしい！ very good !
You could you leather pulley belts. Won't slip.

Terimakasih kawan
but where are the instructions to build one?!
