Here is a pic of how the wheels of my car are set up.

That pic shows positive camber on the DFW. If you're running a sidewalls track, I think you'd be better off with negative.

Re: Testing your car on a guided track,when racing on a lane track

Thank you for the advice. You have way more experience than I do on this. I'm going to say some things about what I have read. By no means take this as challenging your experience. I'll tell you what I've read and you can tell me if that is right or wrong. Again, please don't take this as me saying...

Re: Testing your car on a guided track,when racing on a lane track

Take this with a grain of salt, as I've never built a side-guided car. However, here's what I'd attempt to do if my kids' race was on side-guided track: - Set the car up to "rail-ride" on the sidewall. To do this, I'd do the following things: -- Raise one wheel in front -- On the non-raised front wh...

Why can't you make it easy and have an attachment button below this window so you can upload pics straight from your phone?

Re: Testing your car on a rail track,when racing on a lane track

My test run track has center guide strips. I call it rails. The track my son will race on is a wooden track that has lanes. Test track = inside of wheel touches guide. Race track = outside of wheel touches track. Ahhhh...I really dislike the "lanes" style of track. I have heard some ideas for how t...

Re: Testing your car on a rail track,when racing on a lane track

By rails, do you mean the sidewalls?

Most conventional Pinewood Derby tracks use a center guide strip. Is this what your actual race will use?

Re: Homemade track

I would post a pic of the car and track, but I don't see any way to attach a file here.. I like to use Imgur as an image host and paste the bbcode link for the image to the post. That said, it is very hard to say what a "good time" is for any given track. Tracks vary so much, it is very hard to mak...

Re: GPRM: Disqualify after scheduling?

Would you want the races that include those absent cars to only have 3 cars in them (assuming a 4 lane track)? What's wrong with unchecking the pass inspection box for the cars that don't show? Can you unpass a car after the schedules have been built? Otherwise, we have to print out new schedules t...

GPRM: Disqualify after scheduling?

Is there a way to disqualify a car after the schedules have been built? For our DIstrict race, we should be able to get the pre-registration information prior to the race day, which means we can go ahead and build the roster and make the schedules and have all that ready to go before the event. Howe...

Re: Best placement for 3/8" lead wire weights

Hi, VK, How did the workshop go? Went pretty well, all told! I guess we had something like 35 cars or so come through the workshop? We'd look over their design, make any necessary suggestions or modifications, then drill out the weight pockets, drill the axle holes, cut the profile on the bandsaw a...

Re: Design Judging Article

I would hate to see design judging go away.

I sort of like the compromise where a winner of both categories can choose which he wants to win.

I think Scrollsawer(?) had a kid who REALLY wanted to win the design category, but his car was just a little too slippery and he won speed instead. :D

Re: Brand new to forum and pinewood derby

This is stuff you got at Lowes or Home Depot or similar? Finding 1/4" sheeting has been elusive for me.

Re: Design Judging Article

Maybe this is just my bias as one of the dads whose kids usually lead the pack in speed, but I think disqualifying speed winners from design judging is kind of wrongheaded. Yes, I get that you want to distribute the trophies to more kids, but really, if the kids won, they won. Why penalize them arti...
