Re: Big Dreams for a Big Rig - but smaller

That seems like more work? I’m pretty ignorant when it comes to wood working so I’ll take your word for it. What do you suggest 1/4” sheets? I usually find it easier to build hollow boxes than to carve them. Actually, I've found it easier to build other shapes rather than to carve them. And I gener...

Re: Big Dreams for a Big Rig - but smaller

I purchased a 3x3x12 piece of balsa wood which I will whittle down to be the cab. Hollowing it almost completely out so it is more a shell than anything. When I've built cars like that, I've avoided all that carving by building a balsa or basswood box. Where the corners are rounded, I first reinfor...

Re: Pit Road - Car Parking

We have 100 wood blocks measuring 3/4"x1 1/2"x6". I’m guessing this just high end centers the cars? What piece of lumber did you choose for this? I am thinking a 2x6 with 3/4” rips would work? I assumed that it was nominal 1x2 lumber like what I used. Ripping 3/4" slabs of 2x6 lumber could work, al...

Re: Pit Road - Car Parking

I've seen people also use 1"x2"s or cardboard box tops. When I have displayed my own derby cars for viewing, I've just used pieces of 1x2 lumber. But if the cars are going to be moved and replaced several times (i.e., for an actual race), then I'd secure the pieces of 1x2 lumber somehow. A very sim...

Re: Stop section

Any suggestions on how to improve this stop section so that it is less of a demolition derby at the end of each heat? Yeah, our old track had a stop section like that. We solved the problem by building a new track with a completely different type of stop section. Go and do likewise. Okay, you don't...

Re: -|||===[ Check Your Rules ]===|||-

Yep. We aren't BSA, but when there has been a regional derby, we have provided the rules to the regional derby to those who were interested, but we haven't changed our own rules. Fortunately, there haven't been any big issues with the regional derby rules (such as a "four on the floor" rule). But we...

Re: Non-tungsten, non-toxic car

BTW, there are still plenty of pre-82 pennies in circulation - a random sampling from my sofa turned up 6 among 32 pennies. :) Another BTW, those pre-82 pennies work better in souvenir penny presses than the modern pennies that are copper-plated zinc. But yes, pennies are easy to use, easy to find,...

Re: Moving a racer after heats have been run

Our Pack and District requires the scout who owns the car to be in uniform, check the car in and race it. In my 35 years of being involved with the Pinewood Derby I have never heard of someone else handling a scouts car. If this was some special circumstance then I would like to bring it up at our ...

Nice job!

Years ago, I build a Hershey bar car, but that was back when Hershey bars came wrapped in foil, with the paper label wrapped around that.

Re: Tips for winning the SLOWest Car?

The idea could be taken even further by gearing to a flywheel. Yep. That's how those flywheel toys work, where you roll them across the floor or table to spin up the flywheel, and then you set them down. The flywheel keeps spinning, and it's geared to the wheels, so the toy rolls across the surface...

Re: Tips for winning the SLOWest Car?

The challenge is to make it to the Finish line but be last in doing so. Absolutely. The most extreme "slow car" would be one with the wheels glued in place. It won't leave the start gate when the pin drops. But it also won't cross the finish line, which is usually a requirement for "slow car" compe...

Re: Help Cars Finish!

When we built a new track, we kept a section of the old track specifically to check the cars on registration night. We set it up on a table with one end slightly raised, and encourage the kids to make sure their car will roll down that test section of track before they check them in. But the change ...

Re: Hello brand new here.

My experience with Krytox is that the spin test doesn't last as long as with graphite, but on the track, under load, the cars are at least as fast as with graphite. Plus, it's a lot less messy to have Krytox at our workshops than graphite (which always left a big black mess). But I'm more experience...
