Re: Graphite on wheel tread

The only time I'd want a slippery tread is if I were building a 4-wheel-touching rail rider, and I wanted minimize the traction of the 4th wheel as much as possible.

Re: ZEP DRY GRAPHITE???

Anything liquid combined with graphite I have read will alter the way graphite slides in microscopic plates over itself. Liquid anything will seemingly alter graphite's effectiveness. Stick with Derby Dad for Hire graphite ranked #1, or Hob-e-lube with Molybdenum added to it ranked #2. Ranked #1 by...

Re: Burnishing wheel bores with graphite

When we have to use graphite (not as often these days, thank goodness), we burnish with a metal rod (one of those straight axles from the Pinecar kits works well). In order to keep from distorting the wheel bore, I get a foam rubber pad that we use to press the wheel into as we roll it.

If you're getting migration to the axle head both forward and back, you're probably pretty good.

Re: First pinewood derby experience!! And now a few questions...

Since you're running bent rear axles, there's a lot of speed to be either lost or gained depending on how well you've eliminated any potential toe-in or toe-out in the rear. Have you done any testing for that? I didn't read much on how to check toe in or out, so that is something I would really lik...

Sounds like you've done your due diligence with prep on the cars.

Re: First pinewood derby experience!! And now a few questions...

Here was my car. I was worried when pressing the nails in that the body would crack. I could feel the slot spreading apart when pressing in the front wheel nails. http://i1156.photobucket.com/albums/p578/megajoules/Scouts%202018/2018-02-24%2008.06.15%201_zpsu5uahrl7.jpg I like the Pro-Axle guide fo...

Re: First pinewood derby experience!! And now a few questions...

If you break 3 seconds on stock wheels and axles, that's dang good. That said, remember that track times vary widely, even for tracks of the same length and same brand. Heck, the "speed" of a track can change just by setting it up in a different location. Don't get too hung up comparing times from o...

Can you post a link to your rules? If I can see the rules, I can give my recommendations for what I'd do if I were trying to squeeze more speed out of the car.

Re: Can I have some help?

What tools do you have at your disposal? I have a hammer, some spare axles, card stock for wheel spacing, screwdrivers, and a lot of other stuff. What kind of tools are you talking about? The tools they recommended online were the Pine Car Axle Slot Jig, Pine Car Wheel Alignment Tool, and the Pine ...

Re: Can I have some help?

Hello guys I need your help again. I am now installing the wheels and axles and I am trying to install them straight and square to the axle hole. I have been watching some videos on how to do this and they all recommend a tool that I don't have the time to buy right now. Is there a way to do this w...

Re: Wheel Bore Wax?

If you're going to use the Liquid Glass strictly for polishing wheel bores you might decide to sell some. So very little is used a 16 ounce can will probably last forever. If you advertise it in your area where shipping doesn't become involved and get 3 or 4 dollars for a small amount you will soon...

Never tried them, but they look like they'd be a decent final polishing step.
