I'm rooting for you, man!Updating my coaster blog:
Getting down to the wire, but I'm at 85%. Lift system and a little bit of decorating of the car, then it will be complete. The release mechanism works like a charm (even though I encountered some issues, which I believe will be solved by a flyback diode), and even though I had to shore up the track some more due to the heavier car after adding the electronics, it rolls great (and fast!) around the track with no problems.
I was successfully able to use the Harbor Freight $20 screw boat crank and attached my seat motor to it. It works! The great thing about the screw mechanism is that it is self braking and silent. As long as the motor is silent, the mechanism mostly is pretty quiet.
In the attached video, the motor is using a 5 v power supply just to test, but when I hooked up the 20 amp 12 supply, the motor was rolling a lot faster. Was making headway then the rain came.
Unfortunately, hurricane Zeta is heading right for my just finished coaster with only 2 days left till Halloween. It seems right on the cusp of figuring out the lift system design, I'll need to dismantle part of it. Hopefully it won't be too much work. It looks like the fact that there is not much surface area on the track portion, that wind doesn't seem to affect it. There was a near miss of a hurricane a few weeks ago, and the track never even moved in the wind. That was before I added the cardboard. I'll need to cut out the cardboard and probably the "roller coaster supports". This sucks!
Have you seen how most mobile carnival rides, including their roller coasters, are propelled? They have powered tires between the rails that move the carts along as they roll over the top of them.
As am I. This is looking to be a nice project. Seeing the bogie complete the track is promising, however that chain lift system looks painfully slow.I'm rooting for you, man!
