Re: How to build Speedsters favorite car!

I LOVE IT !!!
Never, ever did I think of having a chunk removed from the bar. I think you might have started something. It's the Best of both worlds. It will make people smile and it's designed for speed.

The speed with which you build things is astounding.

Re: Tips for winning the SLOWest Car?

My Pinewood Derby Teams always check very closely the "centripetal acceleration" and "angular velocity" of our cars. This is very important when trying to build a winning car. You too can get a Constant Velocity car for $13.55, courtesy of Whoda. I wonder what "centripetal acceleration" and "angular...

Re: Tips for winning the SLOWest Car?

How about this idea? Build a 1/4" high car, set it up with the best wheels you're allowed to have, rail ride, cut a groove in the top. Build it so it will consistently run the same time to the .oo of a second. Take it to your 35' Best track and start inserting weight in the slot. Keep increasing the...

Re: Tips for winning the SLOWest Car?

Check the Search function. I recall some very clever things posted there. The challenge is to make it to the Finish line but be last in doing so.

Construction of Fat Sebastion's run out tool is shown on Page 64 of Troy Thorne's magazine, Build a Winning Pinewood Derby car, 2013 Edition, $9.99. It can be purchased from Fox Chapel Publishing Co. It's a Great magazine. Yes, all the answers are on Derbytalk but this magazine will speed up your kn...

Re: Weight placement question

John, at this point I would buy Tundra 3/8" rod. Cut the amount you need to get to 5 ounces. Move the rod, starting from the back and move it up the hill starting from where there is enough wood to be able to drill a 25/64" hole in the side of the car. The only way you will be able to add more weigh...

Re: Stretched frame pusher axle Peterbilt.

You will not believe this.
Just yesterday I said to my wife, "Whoda will probably build a whole truck while I'm trying to get mine ready to test just the chassis".
I will not be showing my wife the Whoda Peterbilt. I hope there's an award for design and I hope it goes to you.
Beautiful Truck !!!

Re: Weight placement question

John, here's what I'd like you to do. In your mind, draw a line straight up from the rear axle slot to the top of the car. You'll see you already have a lot of weight in front of the rear axle slot from the shape of the car. Put the wheels on the car just enough to hold them in place. Have your scou...

Re: Weight placement question

I think I can tell you how to do this very easily. It will work the same way if you decide to cut another car and turn it around. When you add the wheels and axles you will have about 3 ounces total. Paint will be about another 3 grams. You need about 2 ounces to reach 5 ounces or 141.75 grams. Take...

Drilling holes or bending axles

To Derby addict, here's my opinion and I'm sure you're going to get many others. We're dealing with Scout Racing. Bend the axles. Buy The Pro axle guide $10.95, Pro Body tool Axle Drilling Guide, $10.95 (We use it to raise a wheel in our workshops) and a Pro-axle bender $79.95. You can have any bend...

Re: Hello brand new here.

I would suggest you educate the Inspector how to identify a lightened wheel, such as the 1.8 gram wheel. Give the inspector one of the lightened wheels so he/she can compare it to a stock wheel. The inside rim stays stock but material has been removed. The outside step is normally removed which allo...

Re: Hello brand new here.

I learn something new everyday. I've never heard of anyone not allowing a regulation BSA wheel made in the USA to not be allowed. I wonder what the reason could possibly be?

Re: Hello brand new here.

Congratulations. That's a Great book. The Pro Wheel shaver costs $42.95 but it requires another tool called the Pro Hub tool that cost an additional $10.95. My personal choice is to buy 3 sets of the Preferred numbered wheels (2, 8, 15) and that will automatically give you 4 sets if you are allowed ...
