Re: Mousetrap Vehicle B
Last year, we had a similar issue, and to fix it we used washers when attaching the CDs to the axles. We found these rubber washers at Home Depot, that matched the inside diameter of our CDs and the outside diameter of our axles. We glued the CDs to the washers, then the washers to our axles. This basically eliminates wobble, so long as you glue them firmly and ensure that the CD is perpendicular to the axle (90 degrees).SirBobo wrote:Do any of you guys know how to reduce wheel wobble?

Re: Mousetrap Vehicle B
No problem, here's one like what we used, but you could always use something similar. the washer

Re: Mousetrap Vehicle B
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.

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.
