Whoa!

The silvered wheel spokes are a really nice touch, and the Sharpie approach looks like a tidy way to detail a wheel... we'll want to try that idea at some point. :thanks:

Re: Microwizard Fasttrack Timer Case Build

I recommend storing the timer separate from the track. If I was starting all over again, I would consider a "stackable wheeled tool chest" set... if the largest (bottom) box could accommodate the Q-series timer. I have done some research on this, and have determined that the Husky 22 in. ...

Re: Science Fair

I need ideas on some experiments. The OP hasn't been online since 2012, but for others interested in derby-related science fair (and I suspect there may be many that do such)... I stumbled across an old web site that neatly summarizes a 6th-grade Science Fair project on "How to Build Faster Pi...

Re: In Memoriam: Dr. John D. Jobe

I believe Doctor Jobe would be especially pleased that Andrew got his degree in Physics from the University of Texas and is teaching Physics as he works towards his Ph.D. Funny how things work out. Great to hear from you again, Kenny, and congratulations to Andrew. Is he also working / getting his ...

Re: Cheaper alternative than liquid glass

Make sure the synthetic wax is both hydrophobic (repels water) and oleophobic (repels oil), as I have seen they almost always indicate that they are hydrophobic, but only a few state that they are also oleophobic. Do you know of a specific brand that is oleophobic? Some treatment products I've seen...

Re: Vitamin K builds a Track! (slowly)

I think that these plans will prove quite useful as a rough guide to follow for the starting section measurements and such. :thumbup: The Cub Scout Leader How-To Book might serve as another dimensional guide for the starting section (See pg. 6–28, or 242 of 288); I believe it was the starting point...

Re: Vitamin K builds a Track! (slowly)

You don't happen to know where I might find a diagram of the Freedom track sections? This earlier post points to the location of Micro Wizard's assembly manual, which has a diagram showing where the section joints reside on an assembled track. This post shows a picture of the first mated joint, rai...

Re: Vitamin K builds a Track! (slowly)

the minimum recommended length for the Challenger track is 46.5', due to how fast the track is, which it attributes to the polished aluminum surface. Track speed will be primarily governed by the height of the starting pins above the flat, usually in the neighborhood of about 3-1/2 to 4 feet high f...

Re: Vitamin K builds a Track! (slowly)

Is it me, or [is] the starting ramp as shown in the standard design here really long? It is long relative to both the Best Track and the Micro Wizard Freedom (you can see a drawing of the latter in Micro Wizard's Track Assembly manual ). I wondered if the Challenger track in the video might have be...

Re: Cutting the DFW notch?

My little 1x30 HF belt sander makes it pretty easy... I don't have one of those myself, but I thought that this subject could be a good application for one. If only it was a 1.18+ x 30 belt sander! Hah. It is a good little tool. Harbor Freight was running a 15%-off coupon for Easter weekend for a o...

Re: Vitamin K builds a Track! (slowly)

I guess I need to do some experimentation. The piantedosi tracks are 3/8" thick and they bend fine, but anything thicker than that, I worry won't bend easily, even if cut in a ladder configuration. Yeah, I wasn't suggesting 1x lumber specifically for this application, just citing that as a fam...
