*The amount of work that you put into this: up vote and commendation.*

Also with individually steerable assemblies like this, special track geometry is required. In curves you have to make the track gauge narrower since the effective horizontal distance between the wheel sets gets narrower. B+M, Intamin and all the other players that use this kind of articulation do this. On your tight curves you'll see the guide wheels pinch the track too tightly and bind up.

That was fun! The new cart chassis is looking good too.

Dude. So happy I found you. Thank you for sharing your knowledge and experiements. I wish more engineers and creators posted as many videos as you. Can't get any good info!

Always excited for these vids

These work BEAUTIFULLY will. You have a lot to be proud of. I suggest banking the track a bit more and adding lateral load supporting beams near the turns. Since your coaster is so small scale, the stresses usually localize more dramatically to areas and with this new steel cart the speed is going to be greatly increased. Just a thought !

superb desiign cant wait to see it done.

Great work, so come to Australia and build one for my grandkids hey... lol

Hey Will, I really need your help!! I recently came back from a Theme Park and decided to look at Homemade Coasters and I've come across your videos which are insane. your videos have motivated me to make my own Rollercoaster in my Backyard. I'd like to know what Size PVC Pipe you use, how you made the Rollercoaster pipe bend to make drops and how you made the Wooden cart for The Caution Zone!! Please Respond - Sincerely Jeremiah

This was a great video Your track is awesome!

Add some wheels for under the tracks so there will be a lower percentage of the cart falling of at hills at fast speed.

Amazing. I'm not sold on the PVC with 2x4 supports though. I see this was 9 years ago though. Is the PVC track still there and did it work?

Ever thought about making it fully automated. Chain lift, Chain dog, Mechanical brake, Brake Fin, Control Console, etc? Cool DIY project. Wouldn't mind giving ideas if you ever want to make it automated. (Systems Engineer)

You're missing a roll axis between the front and rear sets.

beautiful

that's super cool

Can u give me links to where you bought the wheels

This is so cool, love it!!!!!!

What's the cost of 50 meters track please and where we can buy the design of our roller coaster.thanks.great videos, congratulations

How did you make the wheel assemblies pivot and rock?

Where is the bottom wheel?

u should add a wheel underneath so it wont fall off the track

I love what your doing with your coaster I'm making one myself and I was wondering if I could buy this Steel Cart Prototype off you...the only thing Im concerned about is the width of the cart itself so I would need to know the PVC Pipe width and the wooden intervals width inbetween the PVC pipes, so I can adjust my track...The payment method would be through PayPal and I willing to pay 100ish USD...And I would need you too add wheels that go on the bottom of the tack for stability if you would like to do this deal please contact me though KZfaq, Thank You!

This is so cool. Someone is definitely going to die on this.

can you pls make a video on how to make a cart

0:12 when a 14 years old treis to build a coaster btw 2019???

I'm just wondering if you needed a permit to build that.

How much weigh will it stand and will tje screws bend or come out with the wight

hi will pemble. i live in denver. Can you build me a roller coaster with a 2 loops and a 2 corkscrews and on the 2 steel cart, like a Multi-Inversion coaster. i would like a lap bar restraints on carts please

are you going to build a lift hill for this?

Up stop wheels?

create a manufacturer with other backyard coaster makers

U are an awesome inteligent man

So the cart did not have up stop back then?

How did you make the wheels be able to pivot?

where did you get all that equipment will

I challenge you to build a roller coaster 40ft high because this rollercoaster looks 25ft

Esses canos aí são de ferro ??

u are awesome

You should make it go backward

would you adopt me?

ปากมากแท้บักอันนี่แหม!!

You were bored

Always excited for these vids
