This is not my idea. It is a re-post from a forum.

It mimics a "profile gauge" tool but is made from bbq sticks and cardboard: http://www.amazon.com/Plastic-Profile-Gauge-Standard-Width/dp/B003A07NBG
Remember to rate this 'ible if you think it's useful :)
Bonus: A FREE 3 MONTH PRO MEMBERSHIP GOES WENT TO the first one to post an instructable of their version of this tool including a VIDEO. Post a link to that 'ible in the comments below. Yeah.
WINNER is Mr. Roshy10. Show him some love.
And a Warning from Wroger-Wroger: Be careful not to let stray bamboo skewers or their tips, skewer your foot. These bits can lurk in the carpet waiting to strike.
Step 1: Materials
- a bunch of bamboo skewers (or straws)
- enough corrugated cardboard to cover your project
- some sort of a marker, like a sharpie
Step 2: Insert Sticks
Next, cut a strip of the corrugated cardboard and stick the bamboo skewers through the grooves/holes/openings of the cardboard.
Note: This picture shows a skewer through every other hole but the resolution could probably be doubled by inserting one in each hole.
Step 3: Use!
Then, position that funky tool you have fashioned over the compound curve you want to duplicate, and gently push on the skewers until they just touch the surface. Hold the cardboard level.
Step 4: Trace
Here's a look at the other side.
Once you have captured the shape of the curve(s), all you need to do is to trace it on another piece of cardboard and test fit.
Then, transfer the shape on the material of your choice and cut away.
PS# You can use drinking straws instead of skewers for delicate surfaces, too.
Again, thanks to Mr. (?) Godless Commie over at forum.miata.net for this tool!
