Nice work! I'm trying my best to share this with other people because everybody should at least know there is a channel on youtube where somebody is building this awesome rollercoaster!
Awesome, after seeing your videos me and my dad were going to build a coaster in our backyard, however a tree fell down where we were going to built it, greeting from Australia :D
G'Day, *****! We used to live in Brissy! Such a wonderful place. I hope you and your dad get to build that coaster, and I hope you share pics and vids of the whole thing! Thanks for watching :) Best, Will
No Will, thank you for being open to ideas. I love all your videos. Honestly, if I had the funds and space, I would be like you as well. Keep it up and I will be waiting for your next video. Build to the heavens! Cheers, Francisco
Make sure to center the chain dog EXACTLY at the point where the wheels make contact with the track. You can't just place it anywhere in between the front and rear wheels, or it will lift out of the chain at the bottom of the lift, and dig in at the top. I have 2 chain dogs on mine, one at the front, and one at the back.
Hey THEMINDSHAFT! I was thinking of using 2 Chain Dogs. One front and one rear. And I gotta say, your videos have been super helpful. Thanks for the feedback. This is truly a group effort! Best, Will
Will Pemble Sharing gained knowledge in the maker community is what it's all about Will! I love to pass on what I have learned on different projects. If I can help someone avoid a headache I have had, I'm right there with any help I can offer. Shout at me anytime you have a question on something I've conquered with my coaster, and maybe someday, you can return the favor from the R&D you are doing. ;) Great job so far!
just a idea for what you can use for your anti-rollback mechanism you can use another piece of steel channel on the opposite side of the track with use the same sort of chain in the track but fix it to the channel so it cant move then all you need to do is mount another identical chain dog on the opposite side of the cart. half the engineering required but the same result :)
You haven't really started the track yet, but when you do if you want to make sharper ups and downs and keeping the chain doug/brake fins from hitting the track, you could make indents in the cross-ties where they would hit. Take a look at the top of some of the hills on intamin coasters. Good luck!
Hi Francisco Mejia! Great question. Yes. I've got another piece of channel that I'll put in place to support the returning chain. There will also be a tensioning sprocket in the mix to keep things high n tight! Thanks for watching :) Best, Will
Omg the chain dog mechanism I literally thought of exactly that mechanism in my head It didn't look like it but. I thought how the cart gets pulled up is there's a tooth that has a mechanism stopping it from moving forwards but only backwards by a little piece of metal in front of it while a spring behind it so when it gets pulled up Gravity is pulling on the cart but can't pull it down while the force of the Spring gets pushed back and while there's nothing stopping it it will push the connecter into the chain.
Will! I really, really, really hate to rain on your awesome parade, but the chain dog - I see a potential flaw! :( With the chain channel in place, the chain dog tooth/catch cannot pass through the chain, but can only seat jut the tip of the catch. What I am worried about is that the chain dog will not have enough purchase on the chain itself (without being able to have the chain catch pass through the chain - ensuring a secure hold on the links) I am wondering if the cart will hold with serious weight involved. :( If you have thought about his sorry for the worry, but I am concerned... A possible workaround is to make the chain dog catch shorter, with a more exaggerated catch (the curved piece on the end) Making it shorter and stronger would not allow the chain catch to be pulled to a critical angle where the catch no longer has purchase. (I say this because the chain catch does not pass through the chain, thus having very limited security. Maybe I am over-thinking it...I just wanna see this don so badly! Haha Anyways I hope the best, and I also wish you and the family the best. Always a pleasure to watch your new vids. :) Love the shop, and all the projects...you're family is very lucky to have you!
Hi Michael Gedies Good eye! I'm working on another version of the chain dog with a bit more curve at the end. Also, remember that the chain dog will actually lift the chain out of the channel by as much as an inch when the cart attaches. As for strength, I'll be using 1/4 or even 1/3" solid steel. It'll be hella strong. ALSO, there will be two, count 'em two, chain dogs on the cart. one in the front and one in the rear. FINALLY, there will be a full-on rollback prevention system as well. Dude! I had no idea how many parts and systems are involved here. And it's a good thing, otherwise, I might not have tried it :) But now, the only way out is through. Thanks for watching! Best, Will
II could be wrong, but I think I would put the motor at the top. That way only one sprocket is under high load, instead of two if you put it at the bottom, so there would be less friction and wear on the chain. A tensioner might take a lot of development to get right. Even a chain made of steel will act like a spring (albeit a stiff one). The deflection of the chain under load will be twice as much if the motor is at the bottom vs the top, because the chain under load is twice as long. But, maybe more springiness is good? I'm sure you can make it work at the bottom, but I think there will be less problems if it was at the top. I would hope you are planning to put a safety cage around the chain, so no one gets hurt. On my coasters, I am avoiding motorized chain lifts, which guarantees an adult present to push the cart up the lift hill, as an added safety measure.
Kyle Gregg Yes. Yes, he does? And so should Paul Gregg and Kyle Gregg! Imagine the incredible stuff that could come out of a Gregg-Owned 3D Printer! WOW!
Which 3d printer did you use for printing the chain dog? Btw. I think at shapeways you can also print with metals in 3d, so that would be a way to make it incredible strong
Nice work! I'm trying my best to share this with other people because everybody should at least know there is a channel on youtube where somebody is building this awesome rollercoaster!
The long wait is totally worth it, keep up the good work!

You have the best toys around. Cant wait for the next video.
love this coaster
You are such an awesome dad!

+urbansnipe it would then also be alot easier to implement this along different sections of track where a rollback may be an issue

Great job Will. Are you gonna have a second rail under the track to support the returning part of the chain?
Hi Francisco Mejia! Great question. Yes. I've got another piece of channel that I'll put in place to support the returning chain. There will also be a tensioning sprocket in the mix to keep things high n tight! Thanks for watching :)

Will Pemble has a 3D Printer
Kyle Gregg Yes. Yes, he does?
And so should Paul Gregg and Kyle Gregg! Imagine the incredible stuff that could come out of a Gregg-Owned 3D Printer! WOW!
Great work on chain lift I worked as a ride operater in the UK and the bottom of the lift hill had counter weights on it if that's any help cheers.
Which 3d printer did you use for printing the chain dog? Btw. I think at shapeways you can also print with metals in 3d, so that would be a way to make it incredible strong
I like it that u don't give up and I wish I had a dad like you but mine died ;/
Where can I
buy the chain and sprocket?
Is there a way you could send me the the link for the 3D model for the chain dog please
Are you going to add anti-rollbacks?
i know right he probably will
Hi gostboy56 !
I absolutely am adding an -rollback system. As it happens, that's what the next video is about!
Thanks for watching :)
Best,
Will
What kind of motor
Where did you get that chain dogs or how did you make that
