Google and the Pinewood Derby
I'm certain most of you have at one time or another typed "pinewood derby" into the Google search engine. At the appointment of this writing, Google reports about 540,000 matches for this search term. Of course, many of these hits reference to pages within a given site, so the actual number of web sites is considerably smaller. For example, typing, "site:maximum-velocity.com" into Google shows 345 of the 540,000 listings are from maximum-velocity.com.
So, how many different pinewood derby sites are in the Google directory? I don't know, but I decided to go though the numerous search results pages to see how many sites would exist displayed and to find some interesting sites to share with you. So later on much eye strain, here is what I found. I promise you lot savour them.
Number Of Pages
So, how many search results were shown? I found 706 results (71 pages of ten, but simply six on the terminal folio). These are non the total entries in the directory, but are the meridian 710 results for the search criteria (apparently, this is the limit on the number of results Google will display for a item search).1
Interesting Sites
In general, the search results can be organized as businesses, tip sites, pack/organization sites, Blogs, and news articles (and i band). I accept picked out a few sites and organized them in a way that I hope is more helpful.
StoriesPinewood derby memories abound on the web. The most popular is the "Gilbert" story, which is contained on literally hundreds of spider web sites. I don't know if the Gilbert story actually happened, but it is a heartwarming story.

The Correct Stuff – Choosing the All-time Adhesive
White glue, xanthous gum, tacky glue, hot glue, Super Gum, epoxy, Gorilla Glue; the list goes on and on. With the wide diversity of adhesives available today, it'southward no wonder there is defoliation as to what is the best agglutinative for pinewood derby cars. Then today nosotros will have a look at the nigh common glue types on the marketplace and bespeak how they piece of work with pinewood derby cars.
White glue – This is a generic term for glues such equally Elmer'due south Glue- All, School Glue, etc. This type of glue can be used on forest, paper, textile, etc. White glue is water soluble, so information technology isn't intended for use when the end product will be exposed to water.
For pinewood derby cars, white gum works fine for gluing wood to wood (such equally calculation forest accessories) and for repairing fries or cracks in the wood. It can as well be used for holding the axles in place. White glue doesn't work well on metal, so don't use information technology to gum metal accessories or weight to the car.
Yellow glue (Carpenter'due south Glue) – Yellow mucilage is essentially a formulation of white mucilage that has a college tack (dries quicker, less clamping fourth dimension), and is more durable in wet conditions. For pinewood derby cars, it has the same uses as white glue, except that information technology does hold metal to wood better than white mucilage.
Tacky Mucilage – This is a variety of yellowish or white glue with a high tack, sold for apply with crafts. It has the aforementioned uses as white or xanthous glue. PineCar offers a version of tacky glue named "Formula Gum".
Hot Glue – Hot glue comes in sticks which feed into a glue gun. The melted glue tin then be used to attach a variety of items. 1 benefit of hot mucilage is the very fast dry time (but you take to work fast). A downside is the filaments of mucilage that are left backside – they can be easily removed, but are an annoyance. Also, a hot glue gun and children don't readily mix, as yous can go a nasty burn from the mucilage or the tip of the gun.
I don't recommend hot glue for attaching wood to woods, just it does piece of work well for gluing weight into pockets or holes.
Epoxy – My favorite gum, epoxy, is a two-role glue that will glue about anything. There are a wide multifariousness of epoxy adhesives bachelor, some intended for metal, some for glass/plastic, and others for general use. I like a full general apply epoxy with a five minute set time. You can find information technology Hither.
Epoxy can be used for attaching metal accessories to the automobile and, since it does not compress when dry, it works well for gluing weight into holes or pockets. It can also be used for gluing wood to woods, but I recommend yellow, white, or tacky glue for that utilize.
Super Glue – Super Glue is a brand name for cyanoacrylate (CA) adhesive. This glue is very strong, especially when gluing not-porous materials that contain traces of h2o. Information technology also works well on human skin. Unfortunately, super glue has a depression shearing strength and does not work peculiarly well on wood. So I don't recommend it for pinewood derby apply, except when a quick repair is needed at a race.
Gorilla Mucilage – Gorilla Gum is a brand name for a polyurethane agglutinative. While setting, information technology expands to fill up gaps, and tends to piece of work well when attaching wood to wood. However, for fine hobby work the expansion during setting can cause significant problems, so I don't recommend this glue for pinewood derby utilise.
Pinewood Derby Car Showcase
Dune Buggy: Scott Wheeler
The Cubs in my Pack e'er like to requite me ideas for the side by side year's "Step Car" and this was one they gave. It was made after an actual dune buggy that a Cub's father had in his garage. I used a wire clothes hanger and a derby kit to create the motorcar. It ran very fast just was a little tail heavy.
Dragonfire: Richard House
This was our first Pinewood Derby car e'er. The car trunk, accessories, and press-on decals were easy, merely the car was pretty fast too, having the 5th fastest combined times in our competitive Pack and won 1st in the Tigers race. The engine/muffler on the back was originally designed as underside weights, but worked nicely to identify COG toward the back at i 1/2 inches from the rear beam. We learned a lot of things to brand our next auto even better and faster.
Remote Chance: Dick Roussin
This year my grandson Dylan and I decided to sacrifice a little speed for inventiveness. We found an old DirecTV remote control which was exactly the right width and fastened information technology to the official BSA block. Aerodynamics and center of gravity weren't ideal, but the car placed first in Den and offset overall (~fifty cars). This was our 4th consecutive year winning the overall title. Equally in all of the past years, we used Maximum Velocity Max-Five-Lube and tungsten cylinders to proficient advantage.
Q&A
Nosotros take to build Cub Scout and Awana cars. Since the Awana wheelbase is centered, would it be ok to use the same weight position as on the Cub Scout automobile?
With whatever wheelbase, you would like for the car's balance betoken to be about 1 inch in front of the rear axle. If you lot gear up this balance point on the BSA kit (which has the rear axle about one-half inch closer to the end of the cake than on the Awana kit), then on the Awana kit the residuum betoken will be less than one inch in front of the rear beam, which could lead to instability.
What is the preferred method for gluing in axles? I previously used hot glue, except last year nosotros went with Elmer's white gum. I was told that if you lot wet downwardly the wood and use gorilla glue it will not foam and works best, simply my past experience is that gorilla mucilage is messy.
I don't like gorilla glue for the reason yous point out.
The strongest mucilage is epoxy. The only drawback is that it is virtually impossible to remove the axles once they are glued in. If you don't intend to remove them afterwards, and so use epoxy.
Otherwise, use a yellow glue like "Tacky Gum" or carpenter'due south glue. As information technology dries, it does shrink, so you accept to add more. It holds well, simply does permit axle removal (grasp the axle head and rotate to break the glue bond).
Accept you lot always heard of "set back axles" – cutting off some wood backside the rear axle and gluing it to the forepart of the car to become the weight college upwardly on the rail?
Aye, this is a common technique to get the rear axle further back and then that the balance betoken can be set further back on the automobile. If allowed in your race, you can generally go some added performance by shifting the wheelbase back. By the style, instead of cutting and gluing the block, you lot can plow the cake over and cutting new commencement slots, or drill offset holes (if immune by the rules).
