My KINGDA KA Model! PLEASE REPLY

Ok so me and one of my friends are going to make a scale working KK model and we had some ideas but I was wondering if anybody else had some decent ideas to make it out of ( i would like it if someone was an engineer but anyone can post a reply !

PLEASE REPLY

use knex

i am using plastic for the trains copper for the track a motor and guitar strings for the launch system but i and not sure about the brake pads and breaking system

ooohh, guitar strings good idea, sounds...advanced

thanks bryan

how'd you know my name?! jk, profile I know

brakes? maybe teflon or something that doesn't move? :S (could get worn down though). As for the copper tracks, I think aluminum is easier to work with. Just curious, specifically why did you pick copper? Do you have ready access to some or something?

^I don't think you can buy aluminum track material at a place like home depot. It's also harder to connect especially by weld because of aluminum's oxidation rate.

You must be good because I tried to make a HUSS top-Spin a few years ago, without the model kit and it was a disaster. The electrical part was going to be a nightmare for me too. You can do it. How high are you going to make it?

umm I wouldn't suggest guitar strings for the launch unless they're very broken in because they aren't exactly the most flexible thing ever.

As far as track, I dunno, I'd say unless you have a good way to shape it smoothly, don't use copper. Aluminum is way more ... shapeable if you will.

why is this topic posted on the trip report forum?

Good Question...

But as woodie man said, very very hard to weld together. It takes the perfect amount of heat and just the right application otherwise you could screw up an entire peice.

How into this thing are you man, lol. Cus if its just a phase cus you recently went to the park I think you shouldnt put to much money into it. But if your into it, A working model of a roller coaster has to be SOOOOO carefully calibrated to run. I reccomend looking at these, www.coasterdynamix.com , They are really nice working models.

I am working on a roller coaster model myself, Im focusing on detail more than dynamics(motion) so I'm using rubber for the track.

^^I believe you also can't weld aluminum in open air because of something I don't remember. That's why the insurance for an all aluminum Audi A8 is much higher than the identical steel Volkswagen Phaeton. If you dent the doors, they have to send out to Germany for new ones.

How large are you thinking about making this thing???

Fishing line could be good for this depending on the size of it. If you don't mind the shape the supports are in and how they are attached. Get alluminum item product, its really sturdy and easy to attach stuff too. But its not good for welding so if you absolutly want it welded dont use it.

u should make it real hydraulic

I believe it is illegal to self manufacture any product that will contain a pressurised material, so making hydraulics isn't possible. You'd have to buy the parts froma specialist company.

Also, why not just use steel for the rails? It's cheap, strong and bends easily into shape, although it is slightly heavier than its friend Aluminium

7 feet tall and 17 feet long

sorry about where i put it i just want to let you know i think i am going to use steel and soder it together but keep on posting your ideas

As far as i know hydraulics are not prohibited. (at least not in holland and not in the USA, but this can differ from state to state). But, you are not allowed to use very powerfull hydraulics, there is a limit set on them and i recommend you to look this up .

For the launch system you could also do something with elastics, its less sophistacated and a lot easier to build. Brakes. Well, you could try it with magnets like the real one, but on a lighter note: Put one + magnet in the train, and lots of - magnets in the track. Make sure they are not to strong . Just run the train over it and put in as much till it nearly stops. Just some thoughts . I think its going to be a hard project, but looks very fun to do .

I meant you cant make your own hydraulics

how about pneumatics (i know i spelt it wrong)

my final sciene project might perhaps be a hydro-coaster...we'll see

An air launch might be hard for this too. But you might be able to get something to work by blowing in a tube.
