Okay, so im building this coaster on my free time, that is totally custom. I haven't figured out how the chain will work yet, but here are some pictures of what I am on. The captions will tell more information on the coaster.

And here is the inversion. It will look a lot better later. Check back for more updates possibly tomorrow!

The steep drop with good airtime! The drop was hard, because I had to try to find a way to keep the ''flow'' of it.

Update!

In this update, I have started the second inversion (barrel roll), and it is taking a long time to find a good way of building the supports. I have the first inversion done (and tested) and I am replacing certain parts of the supports so it will look better and be stronger.

 

Enjoy!

as you can see, this is a very long barrel roll. i didnt make it small and tight because it would need a lot more speed to make it through.

Wow! It's really hard to make inversions! I should post a pic of my barrel roll! My coaster is launched though. It's pretty cool! I use this pulley system with rubber bands attached to it. Then I run a string or wire through the pulley down the launch track and just tie it to a k-nex piece and that hooks onto the back of the train. I installed a quick release mechanism too and the train rockets up about 6 feet in like 1/2 a second! It's pretty awesome. I installed a brake system too!

 

Gee, I really know how to go on and on!

 

Here's my barrel roll. It might help a little:

Hi-res so you can see them better!

Update!

I now have put the rail on all of the track so far so I can see if the train will make it all the way through. At first it didnt, but I made big changes to the support structure and that helped a lot. So today I have the drop done, first inversion, and the second inversion. I still havent found a way for the chain to work.

 

So anyway, here are the pictures.

Check back for more updates to see what the coaster does next!
