Re: Performance Tracking Software
The Demo Mode does have some limitations. You will not be able to import or export data. The timer interface will work, so you can test it with your timer, but you won't be able to save the times. You also will not be able to manually enter run data. Hey, I've got to give people a reason to purchas...

Re: Front nose of car, shape, aero, thin to win ?
Yes, I am familiar with wind tunnel testing (I have a degree in Aerospace Engineering). Still the comments don't make sense to me, unless the wind tunnels you are talking about don't have the capability to test at PWD speeds. I'm just trying to understand your comments about "aero not coming i...

Re: Front nose of car, shape, aero, thin to win ?
So much more speed is there, with different axles, lighter wheels, the wax/oil process. I am re mentioning what I would like to know. The scale speeds with correlation to scale air flow that it creates. Sporty, I can tell you that my typical adult league car, a NPWDRL Street Stock, that runs around...

Re: Performance Tracking Software
but if I could make a wish it would be for the software to calculate the intervals at a minimum. I'm not sure that I follow you on that. The sensor intervals? Maybe I need to call it something else? Incrementals? I have one sensor at the bottom of the hill and another one foot after that and one a ...

Re: Performance Tracking Software
quadad, I have six sensors on my new track. I had four sensors on my old track but I had it drilled so I could move two of the sensors around. When I bought the new track I decided to just install the max my timer could handle from the get go. I don't regret it. I use the PDT3 software right now, it...

Re: Performance Tracking Software
I would like to see it work for six sensors at a minimum instead of just four. One file per car with the ability to have multiple sessions per file. It needs to be able to show the average time in the session for each sensor and the standard deviation for each data group. It would be great if it cou...

Re: World Record Run
Yup! Should work. :) You gonna cut up your FastTrack Timer? :) Or build one with an Arduino? If you build, you don't have to worry about a start-gate trigger ... just start the timing based on the trigger of the first gate on the flat. Wonder how many split points an Arduino could time accurately? ...

Re: Wheel runout quality report
Given that you are sorting wheels for Mid America, I can assume that you will need to run them with the tread edge intact. You might find it useful to check the lateral runout, the wobble, to sort your pile further.

Re: Painting in humid weather
Bracket, Very cool looking car! My son loved it! I'm sure your son will do a great job and have fun doing it. My boys are very heavy with the paint, it's hard with little hands but they enjoy it. I hope you are having a warmer day in St. Louis than we are in Kansas City! First snow was last night, ...

Re: Painting in humid weather
bracketracer, The paint is enamel. I think I will paint the base then hit with enamel clear and let it sit a week in the warmest part of my house. Then I will try to paint on a dry day. The car is going to be competition orange with some white grazing both flanks. The stencil will be a home made ti...

Re: Painting in humid weather
That's impressive work, bracketracer. Those are very clean lines from just holding down on the card stock. You have "one of a kind" set of flames. Good Going.... Thank you! I'm happy with the way it turned out. If you dust the paint on a little at a time it works better I think. If you bl...

Re: Painting in humid weather
What kind of paint were you using Seth? If it's enamel with no hardener I would let it sit a week. If it's cool and damp you might be able to use lacquer without it blushing. Hot and humid weather will make lacquer blush for sure without a slow dry thinner. I painted this car last week over the holi...

Re: Building a wooden track. Which surface?
I used Baltic Birch plywood for mine. 3/4" thick for the track section connectors and supports, 3/8" thick for the racing surface and 1/4" thick for the guide strips. Finished with shellac. I considered using polyurethane for a finish but I thought the shellac would be easier to repai...

Re: BSA axles vs. plated oversized axles?
What if you took an inexpensive plastic (or metal) dial caliper, closed the jaws, and where the jaws are beveled at the tips, take a 1/4" or 5/16" center cutting end mill and spot face where the jaws come together? Take it down so the jaw where it's spotfaced is say .010" thick. The s...

Re: BSA axles vs. plated oversized axles?
bracketracer, Doc Jobe claims Hodges Nickel plated axles will give a car length advantage. True, but Hodges axles are aftermarket machined axles and are larger than what you have when you polish a stock BSA axle IMHO. The Hodges axles are machined to .089" +or- .0005". The BSA axles aren'...
