Derby Talk

Why would graphite slow down a car. I will try the wet 400 and see how that works.

I have always done a final polish of the tread with graphite, should I stop doing this has anyone done any testing to see what the differences are.

After truing my wheels on the lathe I need a good method to polish them to get the tread shiny and glass smooth.

Yea the street car thing was a stupid remark I thought because most all cars have some form of suspension or tires with air that would help in equalizing the pressures for all 4 wheels.

Taking a copy of the email with me is a great idea.

I remember the first year we was in scouts and did pinewood derby. The rules clearly stated only 3 wheels must touch. I was showing my car to a couple parents and was explaining a couple things to them such as you only want 3 wheels touching and they said they wish they would have done that and afte...

I have been to district before but the rules was the same as our pack race so there was no worries. I am still not worried because he is relaxing this rule so I will not have to build a entire new car. Almost every car I have looked at has never been perfectly level on the ground because without som...

I read the district rules to make sure our car is legal for the district race and the rules say all 4 wheels must touch. Our pack leader and den leaders let everyone know up front that it is a good idea to place one of ...

Other than maybe grooving the axle to act as a reservoir for the graphite is there any other tricks to keep as much graphite in the axle/hub as long as possible.

Stan Pope I made a mandrel set like yours and it is much faster and nicer than what I was using. Thanks for sharing the great idea

I did a test using Duplicolor, Krylon and Rustoleum and all three crinkled on me after drying for 1 day and topcoating with krylon crystal clear. I have cleaned, sanded and repainted both cars that was ruined and currently have them in my powder coating oven set to 100 degree's. I am going to leave ...

I didn't think about the filling and re-drilling the hub. That is probably why it is in there. Thanks guys.

Our rules state the axle can not go under .084in. My question is, is it better to have the smallest size axle or one that is just under the hub size. In other words, with all things being equal if the hub size is .092 would a axle that is .091 be a better choice or would a axle that is .084 be bette...

Hi guys, I have a question on painting my sons cars. I have been trying to use krylon and the base coat keeps crinkling after the second coat is applied. Here is what I have been doing. 1:Sand car smooth and clean. 2:Apply krylon primer and allow to dry. 3:Apply krylon gloss black paint and allowed ...
