Re: Opinions of the group

After re-reading your initial post I see another observation you had about the fast kid now being much faster than in the past. When we ran our Pack races our car was not as aggressive as it could be. If we qualified for Districts we got more aggressive with weighting and even removed more wood from...

Re: Opinions of the group

Fast cars can happen. The adult should help the kid build the car. We set track record with a 2.90 at our District last year with LED lights on a 42' Best Track and took 1st at NSC Council race. A couple days after the District race I send an e-mail to the coordinator making a few check-in suggestio...

Re: Any recommendations for car design? Help appreciated...

After epoxying the plywood to the bottom we cut out the rear weight pockets 1/4" deep and epoxy in the 12 cubes. We let it cure then cut out the front weight pocket 1/4" deep and glue those 6 cubes in. We then cut the center down 1/4" deep from the bottom also. Next we belt sand the top until we sta...

Re: Any recommendations for car design? Help appreciated...

We cut our block down to 3/8" thick or so then drill our holes. We then epoxy 1/64" plywood to the bottom with the grain opposite the block grain. We then router out our center section and weight pockets 1/4" deep. We finish by running the top on a belt sander until the whole thing 1/4" thick. This ...

Re: scroll saw topic.

Perfectly timed as I'm now looking into these. I'll have to re-read this thread and really study your pics to get a handle on this. Thanks.

Re: workshop layout questions

Thanks guys. This is the kind of detailed info I need. I'm afraid of kids not not getting cars finished in time.

You guys are costing me money and I thought we were done with t...

Re: workshop layout questions

I was considering taking a bunch of blocks and cutting them into about 6 different shapes. I would take maybe 3 blocks and cut them into 6 wedges. I'd leave a few blocks uncut and the kids could choose from any shape they wanted. This would limit the amount of use the bandsaw would get because only ...

workshop layout questions

I'll be running a workshop for our first-ever church pinewood derby. I think we'll have to limit the number of kids building to around 30. I've been reading a ton of old posts and getting great info but have some questions. 1) Do you recommend a couple 3-4 hr build days vs more days with less hours?...

Re: church race rules

The story I hear is there was a "World Record or World's Fastest car race," yada, yada, where this young man dressed in a scout uniform had a car where one of the front wheels was moved back in front of a rear wheel. He won the race. The man telling me this did not have a picture of the car. I thin...

Re: Any recommendations for car design? Help appreciated...

We used a router because that was what we had. The bodies looked nowhere near as nice as VK's pic above. One thing we thought the router helped with was it made the corners round instead of square. Our hollowed out bodies then had rounded inside corners that we thought would keep the body from crack...

Re: How to build a car to epically fail?

How about a simple propeller car but run the motor in reverse. It would probably go down the hill but at some point it would stop and try to back up the hill. I doubt it would be able to make it to the top. That should make everyone laugh. What kind of track do you have? What's the clearance on you...

Re: church race rules

Good points Darin McGrew. 1) I should leave out the "as provided" to clear this up. 2) I'm providing Nyoil II because it's a fraction of the cost of Krytox and church is paying for everything. We took 7th place at NorthernStar Council 3 yrs ago running Nyoil and all stock parts so I'm guessing we wo...

Re: Newbie Axle question

http://i1126.photobucket.com/albums/l618/tschidc0/derbycar%20weighting%202016.jpg We drill these 2 holes under the axle in line with the shaft. It seems to make sliding axles in and out easier during the build. When time to install for good we hold the bottle of Formula or Elmers glue tight against...
