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

I'll see what i can do to start a topic about scroll saw tip's and ticks as well soon as there seems to be a need with more and more people looking to use them in building there car building or looking to brush up on scroll saw skills. 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 c...

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 gues...

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...

Re: church race rules

duvet, I've never done that type of testing but it sounds like a good idea. How many .000 of a second have you ever gained or lost doing that type testing ? If you reached a certain high speed at a certain setting were you always able to regain it? It was our first and only time doing that. We ran ...

Re: church race rules

Thanks guys. I appreciate the passing forward of experience. Going down to see the author of our NSC rules tomorrow night at his derby workshop. Awesome place. We were there once last year and I saw moms, dads, grandparents and big brothers working with scouts building and tuning cars on his tracks....

Re: church race rules

I looked at that H57 block you mentioned. Very good idea. Could I pre-cut some 1 3/4" lengths of 3/8 threaded rod or steel rod to use in place of the lead?

Re: church race rules

Good ideas Speedster. I was thinking bent nails because I knew if they at least had some steer they would not death wobble and all would at least make it to the timer. Also we could have a few tuning boards and let the kids play with twisting nails for steer. Then kids could decide how much steer th...

Re: church race rules

I think we'll be providing BSA kits and will have extra BSA wheels and axles on hand for kids to choose from. I'm thinking rules like: 1) Maximum length 7" long 2) Maximum width 2 3/4" wide 3) Maximum height 4" 4) Must use stock kit wheels, block and axles as provided 5) No reshaping ...

church race rules

Hi guys, We've raced scout races but never were involved in operating a race from start to finish. My church asked me what it would take to have a derby event for neighborhood kids and members. I figure one night a week for 4 weeks to build the cars and then a Sat race. We've been racing under North...
