Never knew I would be a car builder but here is a project that I have been working on the past two weeks. I am not Henry Ford, but I did give it a heck of a try. Little background; 2 weeks ago son came to me and ask me if I would assist in building a CUB MOBILE for a race on June 8. He is the Cub Master, has a 7 year old in Cub Scouts. Not knowing for sure (but with great expectations) I figured the question was loaded and he was asking if I would build a Cub Mobile?
After excepting the challenge I ask for some plans, which he provided along with a car another pack built one year ago. The boys in the Pack requested the old car be Blue and Gold(Yellow) Cub Scout colors and the new one be Red, White and Blue.
The construction of the car is 2×4’s, 3/4” plywood and or 1” X’s. The wheels are wheel chair wheels covered with plastic paper plates.
WE used turn buckles to hold the back axle stable which also acted as shock absorbers for the rear.
The most difficult part of these cars is the steering. These cars race straight downhill and the objective is no turning or limited turning. Needless to say there were numerous crashes throughout the day and several cars actually flipped over. NO ONE HURT> WE had to repair the car each time it was crashed because of soft wood bolts and screws would either pull out, loosen up or wood would split.
The front axle was held on with a 5/8” eye bolt and the steering rope was tied to it, strung through the eye bolts at each end of the axle and than held by the rider. We attempted to limit steering to 1/16” on each side, this was very difficult using soft pine. Race results, there were 8 clubs participating with approximately 16 cars and 4 boys per car. Sons Cub Pack swept the 50#-69# class. They won three additional individuals trophy’s, son won the fastest race of all adults, and the big trophy was also won by his Pack for best average speed of all racers. had a lot of fun with this project and yes I did race in the adult class, I built it therefore I had to drive it. They estimated the speeds of the small kids at 15 to 17 MPH and the adults at 15 to 23 MPH. The brake was made of 2-2X4’s bolted to the frame with a doll rod that could be pulled up on and would drag on the pavement. We covered the ends that scraped with rubber bicycle tires or stair treads. Yes each car has a safety belt and everyone was required to wear a helmet. I learned a lot on this project and would utilize more hardwood if I would decide to build another one of these. Unfortunately, we did not get to test the cars prior to the race which most of the other Cub Packs did. The new car we built ran 12 times and had 75% full runs which was better than most all the other cars that were entered. It was fun doing this project but rewarding to see the 7 to 11 years old with so much enthusiasm and interest in driving these cars. Not to mention the half dozen kids that were to scared to ride.

Dave: I am also 64 soon to be 65 and it was a blast riding this. Little scary because you basically have no steering and once the cart starts to veer you have little to no control. I rode It once and had no problem, it went straight down the track, When my son rode it, at the end of the run he had enough speed that he actually did a donut and spun the car 180 degrees. It was kinda like a burn out after a Nascar Race.

Very cool Danny.
From what I’m hearing we may be able to organize a race for us 64-65 year old LJs.
I guess we’re forever young, Iknow I want a try.
