The Womp

For my testing on a rally track I built a launch womp, and bump all as one section
I used 1/4" plywood that had been leaned up at an angle in the garage. My shop is open, and with the humidity in Houston, it didn't take long and the board had a bow. It was then stood up straighter to force more curve into the bottom half.
4 - 2" + wide strips were then cut off of it,
then the 4 strips were glued and screwed together with stagered joints. Final finish is to paint it all with wood glue thinned with elmers school glue, and it's ready for final paint
The whole assembly is surprisingly stiff, but will need supported in a number of spots.
I will use this method to make some other humps and deep dips for the rally track.
(this is also how I make my train layout roadbases, except I use 1/8" thick underlayment)

The curve...as I always called it, the Pinewood Derby curve...is the answer the whomp. I don't think there's much question there. My hurdle was always trying to engineer/build the curve so it was even/level/fair/quality so as to not be worse than the whomp, lol.
shall we do curves next?

Thats cool!
Another cool thing is that white Dodge in front to the left of the house!
Looking to build a short test track. The transition is going to be the sticky part because of the very low ride height of some of my cars. I live in an apartment, so space is definitely at a premium. I'm a newbie, so any advice would be much appreciated.

The plywood thing works great
I have had thru all our soggy winter 3 - 2' x 4' pieces,
I move around outta the way, and out of direct rain
but keep very damp. then cut 4" - 6" strips off of it,
with my saw (while they are srtaight but "floppy"
and clamp to bend and dry inside
laminate them together with good wood glue
and then you can cut them apart if needed
The womp leans against the wall now,
next to the micro drag strip,
the advantage of making small modular stuff
Goat Hill uses the same build technique
it's only 9' long
good luck, and build on!!

I wonder if this curve is not the answer to the Whump...
