the 4 on the floor flat and using the slots just is'nt right.
give 30 scouts blocks of wood nails and wheels and their parents to help.
for the novice push in the nails with the wheels and i would bet 70% of them only 3 wheels touch the ground.


allignment is key

bondo here as well

Note that the location of the CM dictates: 1. Scale under left side wheels and a scale under right side wheels will both read 3 ounces. 2. Scale under rear wheels will read 4 ounces; scale under front wheels will read 2 ounces. Results: 1. If all the wheels participate in supporting the car, each fr...

i whant to say it would be equaly shared among the remaining 3 wheels but after racing stock cars though the different rate springs probly had more to do with it. would tell me that most of the weight would go to the left rear. but the pinewood car has no different springs. i would say the weight fr...

so i should put the weight lower but i dont whant to go through the bottom of the car.
i guess thats why the cubes are better they can be gluen in flush with the bottom of the car.
does this look better.

heres last years car. http://i1197.photobucket.com/albums/aa422/68sportcoup/DSC06143.jpg the weight was 3.79oz the rear and 1.28oz on the rear the total was 5.07. about 75%-25% it was 4 on the floor though the left frnt was the dominent having trouble getting an accurat weight on one wheel. when i h...

believe it or not district races a 49' best track when my sons car got to the third race of 6 lanes it poped the front up on the rail twice in a row i was worried they would dq him after twice. they said do you think you can fix it i think they said i had 2 minutes. luckily when the car was finished...

so my son whent a little thinner with his car this year and instead of lead like we used last year i got some tungsten at hobby lobby but they didnt have cubes only rounds heres what i'm thinking. http://i1197.photobucket.com/albums/aa422/68sportcoup/DSC07799.jpg or this http://i1197.photobucket.com...

i would assume you straighten the axle first and remove the burrs at the point.
otherwise i would worry about making a hole in the slot that is to large.
or maybe you glue the axles in when finished with tunning

so im thinking about cutting 1/4" off th back and putting it on the front. but using lead i wonder if i will sacrifice com as in standerd 5/8 com. or cut the back and put it on the front com may be more like 3/4 - 7/8. i suppose if i cut a 1/4 and lose an 1/8 then in com then in relation to the...

so lets see if i got this right. 3 groups group1-pack-xxx with sub group tiger wolfe bears weebs group2-pack-xxx with sub group tiger wolfe bears weebs group3-adults -siblings sub group adult siblings. i think weel be using perfectN with the racers being mixed up instead of 4 kids racing 4 races in ...

as it states we are going to have our race with another pack. We just bought a best track the two packs whent in on it together. we are going to run the race with the other pack. what would be the best way to do this so that we can come out in the end with all the info we need as in stats for each p...

that is what i was thinking so i bought two big rig kits each came with 2 #2s runout was .0007 on 2 of them. the reason i bought the big kits is that i believe they have been sitting st the scout shop since last year or whenever they came out meaning earlier wheels in the run. maybie i should go bac...

here is what they stated. INSERTING THE WHEELS AND AXLES INTO THE BLOCK: YOU MUST USE THE WHEELS, AXLES AND THE PRECUT GROOVES PROVIDED IN THE BLOCK OF THE OFFICIAL BSA PINEWOOD KIT Extending or reducing the wheel base is not allowed. Use the pre-cut grooves. That's why they are there. You may not r...
