Good job👍🏻, I like it. I want to know one thing, what is the tip of the soldering iron?

Thank you very much for this perfect video ♡

Thanks a lot dude

Just wonderful. I’ve undertaken something similar that I’m working on for my son.

What make is the camping bed you used?

pretty nifty

Once you thought you´ve seen it all... Here comes Copper-Gravity-Creativity 💈

What a great video. No bs unreachable luxury of a setup, everything extremely practical and very well explained.. Mate I wish I was in Scotland honestly, it looks gorgeous

Thank you for the tip.

Mr Copper Gravity, hello. I'm a huge fan of your work. I literally watch all your videos for their beauty, skill and fun. It's nice to see you working in the Short format videos now. Can't wait to see the full story behind this pyramid. This sculpture makes me want to listen to Coldplay for some reason.... ;-p

cool

Nice shape,Im a big fan of pyramids,have you noticed the second ball queuing for the lift is hitting the coil pushing it up off the track

Very cool prehaps the rocker switch could be duel switch so it means not havein to continues reset the rocker

Oh wow, that's fab!!! ❤

When you have yourself, your fuel, with everything in the back, how much does it weigh? Just interested to know. Looks like a great little getaway van for the odd night out, for me, photogrpaphing the night sky in some remote wilderness. I am not light. I weigh 14 stone. I would need to fill it right up with fuel. I have a couple of Bluetti power banks, an inverter, a laptop, camera gear and a little gas stove. All things together, like food, clothes, boots, water, all the things to survive for a few days. Is the maximum carrying capacity about 900-950kg? I know it's the best part of a metric tonne, I would just need to be sure is all.

Where do you get your wire from? And where did you get that multi-arch plate thing from? Excellent coaster, as always!

amazing and so relaxing to watch!

thank you very much the detailed information about the track comparison that i think i will do CMD track instead of CIC to CMD(checked some video but seem not so easy to manage as seem so risky) and CMD to Ben Nevis also pretty although a bit longer.

Thank you for sharing your process. I have added “Making a marble race” to my someday list.

Thank you so much!!! I thought it was going to be tedious❤❤😊😊

Ian... I've been a bit obsessed with the Chebyshev ball raiser and have pretty much copied it for my first ever RBS attempt. Currently learning the ropes with the resistance unit (a lesson in being patient with myself). It's a wall mounted piece and I'll send you a link once I get it done (someday). Anyway... thanks for sharing your methods!

Hi I love your channel and have started making marble runs of my own. You make it look so easy but it is not, but I am slowly getting there. 😅 Can you please tell me where you buy the replacement (cheaper ones) carbon tips from, I have the same resistance soldering iron. Many thanks 🙏 keep on posting I love it!

Dude, I was so blown away by your amazing skills in putting this together. You make it look easy... and I know its not! I wish I could afford one of these, as they are true works of art but sadly my currency is very weak versus the USD/GBP.

That loading system, I think I spent the first couple of minutes just marveling at that genius. Great build design.

WOW … AMAZING TIP .. I WAS SUFFERING 😅… HOW ASBOUT THE THICKER WIRE ? 3MM THICKNESS … WILLL IT WORK

Is the music from Wintergarten?

I'm a retired aerospace engineer, and I spent a few years after I retired designing and building backyard roller coasters with my grandkids. I looked at a loop, and did the calculations in a spreadsheet. I made a video about loops and put it on my CZcams channel, but never made a loop, as the forces and accelerations were too high for my little grandkids. I documented all four of my backyard roller coasters in videos on my channel, and wrote two ebooks I'd be glad to gift you if you contact me. You point out that your coaster, in practice, needed a lot higher hill than the physics equations predicted. I suspect that when the ball is in the loop and under high centripetal acceleration forces (a = v^2/r), they are high enough to spread the track rails and you get extra mechanical friction. You might try more cross ties so the track is stiffer and see if it goes faster? Plus, aerodynamic drag goes up with velocity to the 3rd power, but it's a sphere so the air friction should be low. I believe that once you can characterize your ball drag on a track as a function of speed and accelerations, you could predict with some accuracy your performance before you build. I have a spreadsheet which does this, I'd be glad to share it. I think it is still available for free at backyardrollercoasters.org. And a clothoid loop, with large radius at the run-in and run-out, and smaller radius at the top, will work better than a single radius loop. You need upwards force at the top of the loop, and a smaller radius will increase that centripetal force. I just bought the equipment on on of your videos, and hope to get into this fascinating hobby. Thanks for the videos and instruction.

Fantastic video

You said you no longer use flux, what do you use now?

What is the length of the back of the van ???

That's wonderful! ❤

Fantastic what a great RBS!! ❤

What kind of soldering iron does he use?

I love the bending jig. You're getting really slick curves, plus it's quite pleasant to look at. It's nice seeing your channel grow!

Clicked because autism. Stayed because autism.

Simply amazing. I’d like to see this with some soothing music and maybe slow motion close-ups at times. Awesome work!

It's so refreshing to see someone do a sensible conversion that proves you don't need a whole run of kitchen cupboards, a full cooker, fridge, etc etc etc!!! Just install what you'll need, just the basics! You won't be cooking full meals, guaranteed! After all, you're on holiday, so eat out, buy takeaways, eat junk!! I'm definitely doing this with my next car, probably a Ford Galaxy, or very similar, & like this conversion, mine will be just a simple, uncomplicated sometimes van/or car/or camper, but just remembering that important acronym, K.I.S.S. Keep It Simple, Stupid!! 🤣🤣🤣

Once again a very nice project. I'm already looking forward to the next one.

Background music is too loud and annoying

Outstanding

Nicely done, however...you have to re-visit that motor and clunky switch panel, these need to be cleaned up. Put a much smaller motor at the top so the bottom is clean and uncluttered.

This unlocked a forgotten memory from my childhood! There's a giant Gravitram sculpture by Shab Levy that's been at the Kentucky Science Center since the mid 80s

That poor swan has seen some abuse 🥺

It has to be a 200mm vertical height diff, which is not the same as the length along the track. As you angle the 200mm long track further and further away from vertical, the height difference will go lower and lower. The final track angle looks to be about 45 degrees, so your height diff is closer to 140mm; this is why your diameter had to be so much smaller.

I'm late to the party, but your choice of music is very appropriate.

dove si comprano le sfere in metallo ?

BEAUTIFUL!!

Is it possible to make a loop to loop sculpture.

Mesmerising :-)
