New Items DerbyDad4Hire Must Read!

[DerbyDad4Hire]

We do our best to bring you the very best in pinewood derby. If for any reason you aren't satisfied with a product you get please call me and let me know. I can't help you if I don't know you have a problem. All products are 100% supported and in most cases can be refunded or replaced. A few instances of not being able to replace... buying my DVD and then wanting to return it after it has been watched. Craming axles into a car with light wheels and breaking the wheel while using it to try and get the axle out (actually I usually do make you a new wheel if you need). Race preping wheels and axles and running them and then wanting to return them. If they aren't what you were wanting then please return before you use them.

We are also expanding our product line to include laser cut products, stencils, more fenders, and much more! If you would like to see a product, let me know and I will do my best to accommodate you.

John, if you laser-cut a body pretty much hollow from front to rear (other than possible cross-members for strength), is there any substance that is super light weight to use to fill the voids, other than perhaps balsa? E.g. Styrofoam lightness, but more solid?? This came to my mind when I saw you are going to offer laser cut bodies. Maybe there is something in an airisol can??? I have tried covering with 1/64th balsa and/or monokote, with only average effect, leaving only air inside, and other problems arose.

I use Divinycell H45 that's at least half the weight of balsa. I laminate the body top and bottom using 1/64 plywood with West System epoxy resin. Once done, IMHO, it's lighter and more rigid than solid pine.

There is also a very light 4-6# balsa which you can fill the cavities 100% it is 1/2 the weight of your normal hobby shop balsa. Use medium CA with this balsa then epoxy 1/64 birch ply-wood or carbon fiber and it is bullet proof won't flex or warp and you can't break it if you try. Also will not cause vibrastion.

I'm trying the light balsa in the nose area of two bodies I'm doing now to see if it's easier to finish after sanding down the front of the car. It's a little heavier than the foam but not much.
