Re: First real derby race... wheel advice

Car body doesn't matter. Get the weight right and focus effort on wheels and axles. If your axles are polished and smooth, your wheels are true and straight, and you weigh in at 5.0 with you COG correct, you will do fine. Perfect wheels, axles, and weight on a square block of wood can still win the ...

Re: First real derby race... wheel advice

https://www.youtube.com/edit?o=U&video_id=XwWejEdiyYk I've got a video series on YouTube that shows how we do wheels and axles, it's a good palace to start. There's lots of videos and tutorials out there, and DT is a great resource. Above all, remember that this is supposed to be something fun you d...

I've got a video series on YouTube that will walk you through some of the wheel and axle prep with links to everything you could possibly need. It will get you started in the right direction.

Here's video of the Spitfire Mark III in the first trial run. Best time of the day after graphite and adjustments was a 2.5048, enough to win the outlaw class for our pack.

Re: 2018 Spitfire Mark III

Wow! That's a really nice design. I don't think it would fit our track (the rear wheel would probably drop into the slot for the start gate), but it's still gorgeous! We run on a best track and I made the rear wheel wide enough to ride over the slot thanks to the heads up of some of the guys here.

Re: Excellent Pinewood Derby Youtube Series

https://www.youtube.com/watch?time_continue=3&v=XwWejEdiyYk I have heard from many of our parents that they struggled with knowing how and what to do, or thought that they needed to purchase a ton of expensive tools. I guess great minds think alike because I shot a video series this year to share wi...

Volunteer Thanks

I'm trying something new this year, and wondered what other packs/groups do to say thank you to everyone who volunteers to help put on your races? I'm making wooden challenge coins to give to each adult that helps put on our race, be it in the pits, tabulation, check in, etc. I recently purchased a ...

Re: Advise me on using slots. :)

I wouldn't advise anybody to build a RR car without a tuning board, and that's another thing he'd have to purchase parts for, etc. :) Not if your like Sporty and use a smooth kitchen floor!

Re: 2018 Spitfire Mark III

And build back plate that matches your fender design! Kind of like an air shield behind the fender! Whoda, My thoughts on the fenders are that they may be a "for show" element only. I thought about building out something around a "weighted" air shield that would attach only via the axle nail. The f...

Re: 2018 Spitfire Mark III

Finished up the Spitfire, the track clearance is going to necessitate riding in the "raised" position so no fenders it is. Really happy with the final paint, i did buff and wax it a bit after pics were taken to get rid of some fingerprints and a few small blemish spots. It's shiny as a new penny now...

Re: 2018 Spitfire Mark III

So in considering how I wanted to finish out this car I really wanted to make it look like an old dirt track racer. Kind of a nod to the old belly tank dry-lake mod cars and make it look like something that a guy might have built in his garage post WWII out of an old spitfire airplane. I really want...

Re: Rail Riding Question - indenting RR wheel

Hello all, New member. I’m attempting to build a RR car for the first time. I’ve read in a few places to ident the block at the RR axle groove 1/16”. Our rules specify a minimum distance between the wheels of 1 3/4” which effectively prohibits this technique. If I can’t indent the RR axle groove, i...

Re: 2018 Spitfire Mark III

So I finished up the wheel hubs with my typical method, chucked them up in the drill on my mandrel and did a slow spin against the tip of a silver sharpie. I want to airbrush them to have white walls like the hot rod and little blue cruiser I've done before. Not sure yet if I'm going to attempt the ...

Re: 2018 Spitfire Mark III

I've made a bit of progress, spent 9 hours in the car this weekend (late family christmas get together) so no time to work on derby cars. But I have all the final primer and prep work done for now. In the past I've had a friend of mine who is a very talented painter and airbrush artist do my final p...
