    I am looking for a source(s) for the wooden catapults used in DOE

    WOW! I’m in the wrong business! A $20 caliper and a $.50 bag of M&M’s for $50. Catapults for $350. And we fault NASA for paying $900 for a toilet seat!

    Hello folks,
    While you looking for prices…I have pads of paper and pens that say Six Sigma on them.  Paper is $4.00 per 20 page pad with a n ice cardboard backing and neatly bound with cheap glue acoss the top, and my mass produced pens are $10.50 each and also say “Made in China” in small lettering right near the place where they usually leak from..

    Cindy,
    Six Sigma Tools(SST) carries three different types of catapults. Check them out.

    May I suggest a lower cost alternative that is likely going to be more stimulating for your students . . .
    Paper Helicopters
    Many DOE trainers have used these to demostrate methods with great success. I’ve found the catapults to be too costly (as mentioned by others), too hard to travel with, too prone to breakage, and too predictable (especially with a bunch of engineers who have learned the math behind them).
    Do a Google search using “experiment paper helicopter” and you’ll find a bunch of information. With that, and a little creativity of your own, I think you will find it useful.
    Personally I find it usefull to start with a little two sample comparison (t-test), then move to a 3 or more sample comparison (ANOVA), then on to a factorial design. Eventually you can move all the way to a response surface design, and even engineers find it difficult to guess the interactions between types of paper, blade width, blade length, etc…

    I agree with Doc. Check out this URL of a previous post for a download of a paper helicopter.
