And it's done! Sort of... I have to fix a few things but for the most part it's done. The top lift plates are jacked up and too thick so the ties cannot fit. I am going to re-design them to be a spine rather than a plate. The plastic I used for the spine bends weird. I am thinking about going to the same piece but in aluminum to add strength. Everything works but the chain tends to not disengage from the motor sprocket, so I am adding a guide between the lower lift plates to stop this problem. I still need to design the chain dogs on the train and have an idea that may work. Anyways, here are some pics.

I know this may seem noob-ish, but what do CD coasters have as standard instead of chain?

Please forgive the nooby-ness of this post..

Looks really realistic,

^There is a very long spiral-shaped spring inside a pre-made spine. A motor makes the spiral rotate. The rotating spiral gets the train up the track.

You should try to make a chain guide...

[coastergeekrtc]

Possibly...but that's further down the line. Problem is that the chain guide would be quite large in proportion to the track so I may not want to add it. We will see.

Here is an idea of the new top lift assembly. It will be made from a 3/8 inch square rod milled down to .35 square. Then I will mill the cut-outs and drill the holes. I like this design better since it's easier to work with the rod than the sheet metal. And I can get more accurate results with the mill than the jigsaw.

Lovely, very inovative. I feel that you should finish the coaster!

[The KNex Weasel]

Nice lift there.

Just out of curiosity, what kind of coaster is it (obviously not an Invert)?

[coastergeekrtc]

Floorless train.

[SSCoasters]

beast! very well done.

WHO SPAMS MY THREAD?!?!?!

Um I have no progress on this. Well sort of. I am planning an automated transfer track to be part of the project and so far I've ordered and received materials. But I've been so busy that I haven't even finalized my design.

looks rly nice, i would start working on the layout while the lift s coming along though and i think u should put the chain in a guide so the train can follow the shape of the track back down to the station nw pics soon i hope ;p

Well, he says hes busy. Its only about a month since his last update. I could be wrong though....

[pkiknex25]

His last update was 10 months ago. 1 month ago someone else brought it up.

Let the thread go back to sleep.

[coastergeekrtc]

Sleep thread, sleep. Thou who awoke it shall die!

I have some ideas but have been too busy to attempt anything. I ran into a problem on the lift but I had an idea for some other mechanical projects. If I have any progress I will post it. Until then, let it sleep or die!

[Little Kuriboh]

Or live again! jk.

[pkiknex25]

See you in 3 days.
