Many intriguing woodworking concepts here. Aside from the overall mechanism which is perfectly executed....I like how you made those little rings! I make rings and stack them up to make containers but I have a tendency to overthink / over complicate things. Thanks for the inspiration!
For everyone wondering about the 1.18 X is how many degrees you want to travel (in this case is 360/5 = 72) the formula to get the multiplier is: sin(X/2)*2 so in this case sin(72/2)*2 = 1.18
Pretty smart idea. I would have taken those wooden rings that suspend the balls and routed inside the tops of them to match the curve of the ball. It would have much less friction. Also, you could route the underside of the top disk that rides on top of the balls with the same type of routing bit using a circle jig; so the balls will have more surface area to ride on which will minimize wear.
I would wax all the inner parts including the bearings. That would give the wood a nice protective coating and also help it roll smoothly. I have a set of bamboo crochet hooks. When I got them they were in usable condition, but the yarn would still grab onto the minute fibers of the hook causing annoying drag and unnecessary wear on the yarn. I sanded them with very fine steel wool and very fine emery boards meant for finger nails. Then I dripped hot wax on the hooks and polished them to a nice sheen. Now they work even better with the yarn and it's easier to crochet with them and they don't cause drag and wear on the yarn any more.
Someone has probably already mentioned this (I don't have time or patience to read through a year of RU-vid comments) but the finishing touch to this awesome project should be a skirt attached to the top disc to keep dust out and prolong the life of the whole thing. Great work and demonstrations!
It was very helpful I am making makeup holders for my sisters and mother and I did not want to use plates and marbles so watching this gave me a great idea and will help a lot thank you
To anyone else watching this wanting to know more about how he divides the circle, it's done using what's called "Chord length", the distance between two points on a circle's circumference if drawing a line directly between them. The basic equation is: chord length = Diameter * sin (180/number of holes)
Good design Jack. No need to route out a groove for the balls to ride in. I take it the rings are just to hold the center circle so its lined up with the center of the balls.
Another great idea Mr. Jack! I need something in my workshop for my small cans of stain,and paints,and your lazy Susan is just the thing to bring them all back out of the tote. Perhaps I'll try a free spinning multi-tiered where one level will spin counter clockwise,and another spins clockwise,and vise versa. Thank you; Mr. Jack for another awesome video!
Very clever. Have you made videos showing how to make the measuring items you used in this video? I realize I can go to the store and purchase something similar, but, to me, working with wood is all about the journey, not the destination. Very nicely done!!
Jack, I noticed your hands seems a bit stiff. I have a friend with something similar maybe even the same cause. Based on that I have to give you serious respect, it is very hard to work with and you make it look easy. Great job, keep it up.
+Wolf Angel If I had to guess, rheumatoid arthritis. It's severely painful, and in most cases, the joints freeze up, and can't move. :( Yes, he's *amazing*!
Xayla V thank you. I was thinking that it might be. With my friend though she has a growth disorder where the tendons in her hands did not grow to length and caused a similar affect.
Brilliant - well done, and I laughed out loud when you tested it by standing on it at the end... How about motorising it now aka Matthias Wandel? But maybe don't stand on it...!
Very much so. I may not have noticed if I didn't see the comment, but since you said it all I can think of is my 6th grade friend who held everything in a very different way...
He obviously has something debilitating going on with his hands. Perhaps severe arthritis. I worry, as I had early onset arthritis(psoriatic arthritis), and have had a limp in my left knee since high school. I am a programmer by trade, and some days the pain in my hands is unbearable. I am only 32, but I have already caught myself on bad days holding things in weird ways that is more comfortable. My second love, electronics, is a challenge, as I can no longer '3 hand' solder, as my fingers have lost dexterity. Thank god for helping hands :)
Cat From The Future What the fuck is wrong with you? You seem to have a social awkwardness where you speak without thinking. Aspergers perhaps? You don’t come to someone’s channel and talk about them as if they aren’t even here, never-mind reading your dumbass comment. And to the rest of you who chimed in...shame on you too 👎🏼
Jack , have you ever cut the circle on the table saw before? It is actually a really neat way to do it. I don't have a band saw yet, so a friend of mine made me a jig for this actual idea.
This is a neat idea. However, I suspect some slop (looseness) will develop as the balls wear. Plywood is very hard and rough and the inside of those circles might wear the balls out of round. So might they dry or warp out of round. Have you put this under any strain for any length of time?
Hi jack, you got me thinking how got 1.18. It took me a while since i haven't done any trigonometry for a while and for those who is wondering 1.18 = 2 x sin (36 degree)
Nicely done! Just what I was looking for. I need to make a 25" table. Are those balls sitting on the rings or do they sit inside and roll on the bottom plate?
