Has anyone built a replica of Crash Racers/Sizzlers Curved 180 track? Or other alternatives track
Has anyone BUILD a replica of Crash Racers/Sizzlers Curved 180 track? Thinking of building it without using 3D printing. Fyi, i only manage to think of ideas using plasticine clay, fibreglass, glue on a toilet paper, or even resin. But i still think it wont be as smooth as i like. Just throwing out question if anyone have any ideas or so. Thank you.

If you investigate in the forum archives you can find a lot of information related to the subject, here is something I found.

I have experiments in making an "indurtrial paper mache" slot car tracks
I use minilla folders 
you can make an amazingly flat, smooth surface
You use something flat to work in and build it top first, and layer up the back
use straight glue, NO Water! even to the point of a cleaned dry brush
water causes warping
track below is totally cardboard, folders and high quality thick printer paper
(cars run the flats but I can't get my hiils flat enough for the slot cars,
but hot wheels cars zoom down the hills just fine 
- Nice one man, pretty sick with the curves there. Ill be sure to look into this material man. Thank you so much! — fhk_diecastracingmalaysia
It really depends on a couple of key factors. Do you want to emulate the CR exactly or just get a bit of a bank in your corners, what materials are available to you and what your skills are like - whether 3D modelling or hand building.
All our tracks are hand built out of a product caled palight - basically a high density foam. You can cut a flat corner, then pull the ends in to add a bank to it. You can go a step further and also add a curve to the bank using a heat gun if you want. You could also build a banked corner like they do for skate parks, where there are a collection of triangular shapes cut and glued to a shaped base to give you that same curve. Here's a pic of what I'm talking about in terms of cutting flat and pulling the ends in.
Someone else on the forum did make some curved corners out of cardboard tubes (the large 76mm/3" cores) and they cut notches out of it to fold them into corners and then I think they put plaster over them to smooth out the surface.
- I have saved the thread on the math absolutely invaluable, wish I had it when I attempted the paper slot car tracks — dr_dodge
- Appreciate it man! Ill look into this! ???????????? — fhk_diecastracingmalaysia
