Re: Hello brand new here.

The drill jigs are an investment. They work very well if you buy one of the precision ones, like the Clear Drill Jig. However, bending axles is not hard to do by hand. Here is my method (Stolen from Stan Pope): - Get a piece of pine (or other soft wood) about 1x1x3 (The exact dimensions don't matter...

Re: Hello brand new here.

Now thats what I'm talking about Vikimin K. Ok oil it is. Ill return this graphite I bought. Tell be the greatest oil on the planet. I know there are 2 maybe 3 kinds. Most of the oils available are based on Krytox GPL 100. Some are just pure Krytox, others have additives to (allegedly) make them fa...

Re: Hello brand new here.

Here's my takes: 1. Rules state oil is allowed. My question is should I use oil on a track where most of the other cars will be using graphite? If the car makes several runs I dont want graphite dust getting in my oil tires. Should I just use graphite? My kids have run oil at Derbies full of graphit...

Re: Tamiya Craft Cotton Swab

87106's are the swabs that I use as well. I feel far more confident that my kids (or myself, even) can polish the bores without tearing them up.

Re: Tungsten and Duct tape

Wait a minute VK isn’t the shiny foil tape also considered a duct tape for air conditioner ducts? So it isn’t considered as a duct tape as well! Although I know what your saying about the foil tape As it has the higher adhesion and sticks to most everything. I just had to toss this thought in about...

Re: Tungsten and Duct tape

Very nice, Speedster!

I do something similar, but with the shiny foil tape as opposed to duct tape.

Re: WTB... SILVER BULLET

The Silver Bullet Pro jig has been out of production for quite some time now.

Might I recommend you look into the Clear Drill Jig instead? Star Cars Derby has them, including the one with the new 5th bushing that drills a pre-toed-in axle for the DFW.

Re: Canopy Weights from a Spoon

Thanks for the complement....I just hope they stay on. If anything, they do make it look cool. I updated the Pinterest link with a couple other ones we created. If you have the time, you can get a little creative with the spoon. On one we used the normal shape of the spoon and drooped it to a point...

Re: Canopy Weights from a Spoon

This is a cool idea, btw. I just might have to steal it. :)

How much does the lead-filled canopy end up weighing when all is said and done?

Re: Canopy Weights from a Spoon

I like the look of the narrow end in the rear. Seems like that would technically be more aerodynamic, too. :)

Re: Minimum diameter of axle

VK, that might be true. However, I doubt that any Scout Race, including the Mid America, allows changing the bore size to something smaller. As always, I could be wrong. Rules disallow things like bushings. They don't disallow bore treatments. It is possible one could use a "treatment" that would b...

Re: Minimum diameter of axle

Small axles go faster if the bore is reduced in size accordingly, I believe.

Re: Pinewood Derby Times, Volume 18, Issue 6 - December 12, 2018

Nice topic! A little surprised you didn't mention any of the runout testing tools that can be either built or purchased.
