The trigger PENCIL has to be held vertically when pressing the metal/plastic bait pedal. Hope that cleared it up.Sunshine Ninja wrote:we had the same problem..... we switched to dvds and they work better.
Also... The rules say the trigger has 2 be vertical?

Re: Mousetrap Vehicle B
There is no rule about what material to use for the car, right? (sorry double post) ಠ_ರೃ

Re: Mousetrap Vehicle B
No, the rules do not specify a material, except for the fixed point which must be a paperclip.SirBobo wrote:There is no rule about what material to use for the car, right?
Also, do people suggest to make the car with an adjustable mechanism to allow for calibration, or to make it fixed and eliminate inconsistencies?

Re: Mousetrap Vehicle B
My choice has always been to include some sort of a steering mechanism in the car. You may build the vehicle so that it will travel perfectly straight, but overtime it will be altered. A fixed body/axle doesn't allow for adjustment or correction later on.

Re: Mousetrap Vehicle B
Thanks. We decided on a mechanism that will allow for slight changes in the axle's angle.

Re: Mousetrap Vehicle B
What should you use other than sauter to attach the rod with the string to the mousetrap?

Re: Mousetrap Vehicle B
That's called a Pull Arm. The easiest way is to simply zip-tie it to the mousetrap and then maybe reinforce with hot glue. This is rather robust and also allows for easy removal if necessary.mousetrapfury wrote:What should you use other than sauter to attach the rod with the string to the mousetrap?

Re: Mousetrap Vehicle B
I'm using some clamps...not exactly sure what they're called but they're U-shaped and then they go through some sort of holding device and are attached with washers... I used them to clamp the rod onto the arm of the mousetrap... I'll find out the name of the clamps, sorry I didn't know!illusionist wrote:That's called a Pull Arm.

You might also want to look at hose clamps: http://en.wikipedia.org/wiki/Hose_clampPauly_Rocks wrote:I'm using some clamps...not exactly sure what they're called but they're U-shaped and then they go through some sort of holding device and are attached with washers...
