| Glenn,
What are you racing, and perhaps Not this weekend but in the
future I myself and a friend of mine might be very interested in
helping out we both raced or in my friend case wrenched on FF.
for quit a few years and I also built Fiber Glass body work for
same.
Soory can't make it this weekend I stuck!
Good Luck
Mark Schroder

| Thanks Mark,
I'm running a Lola T640 FF. So far this year I am just running regionals. If
I feel like I'm running ok I will run some nationals. Probably not till
next year.
I'm sure I will be able to use help at other races too. Right now I don't
have anyone who can take this Friday off. My biggest problems trying to
run the car by myself will be -
- the car probably won't start on it's internal battery.
The battery must lay on its side so it has to be sealed.
The sealed batteries don't have much power. The one
that came with the car wouldn't start the car after it
had run for a while. I bought another from Sears which
didn't do any better even when I put the two in parallel.
I just bought another new one which I won't know about
till this weekend.
- with the arm restraints required this year I can't get the
seatbelts on by myself anymore.
- it's usually good to have someone take lap times in case T&S
loses a time.
Thanks,
Glenn

*Looking for some software development help.*
*********************************************
I am on a NASCAR North Team, at the July 15 event at NHIS we where pitted next
to Harry Gant. We noticed that on Thursday July 10 they had 30 tires mounted
up by Goodyear. Gants crew then inflated all the tires with the same pressure
and measured the circumference of each tire, and assigned a number from 1 to 30
for each tire. They then wrote down the circumference and the assigned tire
number on paper.
The next day they came back with a print-out, lay-out all 30 tires and
assigned set numbers to all the tires.
After watching this we could see that this activity does have some major
benefits. As a result I was assigned the task to see if anyone at DEC would
be interested in developing (as a outside of work project of course) a program
that could do the above. I have spec'd out in detail what needs to be developed.
However I do not have the software development expertise to complete this.
We would like to be able to run it on MS-DOS (best case) or on a VAX thru a
dial-in.
Please respond to me at MVDS02::SHOWERS, DTN 264-5098, or Home 883-4267, if
your interested in helping me or know of someone who might be. This could be a
opportunity to get close to a team thats trying to go places. We would like to
be able to use this at the next 2 NHIS events and at Dover.
If your just interested in what I spec'd out let me know.
Thanks
Craig

| Sounds like fun...post a spec & tell us more....
I speak the following flavors:
WATFIV, FORTRAN77, COBOL, BASIC, PASCAL, & an just learning C
I mostly use PASCAL....
JP

| Yeah, I am interested too.
From your description, however, it doesn't sound like it is something
that a typewriter cannot do.
I know BASIC, Fortran, Pascal and a bunch of others that you probably
don't care about, but my pet language is C, which is also what I use at
work everyday.

It's real exiting to see so many of you racer's are interested in helping.
Below is the requirement as defined by our team. I am not sure how to proceed
with deciding what Hardware to run this on. It might be easier to do on a
Laptop running LOTUS 123, (need to come up with the HW and SW).
I am on the HS Motorsports team from Hudson NH. Car #3, driven by Herb Simpson.
Over the last four years we have only run a few races each year and have not
had much success. Two weeks ago we finished sixth at Oxford in the NASCAR North
event. We have decided to run the remaining races this season and just bought
a back-up car that Rob Moroso ran last year.
Thanks for all the responses I will keep you posted on what I decide. Any
additional thoughts are welcome.
Craig
Selecting the Tires with the Correct Stagger
Requirement:
____________
Select multiple pairs of 2 tires per pair from a input list that will vary from
6 to 100 tires.
Input list of 6 to 100 tires will be input by assigning a number to each tire
and that tires associated diameter.
Example:
Tire Diameter in inches and 1/8
____ __________________________
#1 36 7/8
#2 36 3/4
#3 34 7/8
#4 36 1/8
#5 35 1/8
#6 36 5/8
etc...
Up to a max. of 100
Program will do the pair selections based on an input called Stagger.
Stagger is the difference in circumference of the right side tires compared to
the left-side tires. The stagger input will require two inputs:
Input Example of Input
_______________ _________________________
Stagger Input 1 Front Stagger 1 1/2 inches
Stagger Input 2 Rear Stagger 2 inches
Program will select the pair (two tires) that meet the stagger inputs that
where defined. Then print the tire numbers associated with that pair. Each pair
should be labeled as Front Stagger, Rear Stagger and Remaining stagger.
Remaining Stagger will list the pairs that had a stagger value that was less
than both the front and/or rear stagger value. The Remaining Stagger should be
selected and printed based on selecting the largest stagger (first)down to the
smallest stagger(last).
Example Output:
Stagger Tire numbers Diameter
Left Right Left Right
______________________________________________________________
Front S = 1 5/8 5 2 35 1/8 36 3/4
Rear S = 2 3 1 34 7/8 36 7/8
Remain S = 1/2 4 6 36 1/8 36 5/8
Design
______
Approach
1. Input routine 1 for tire #. Input routine will prompt with "Tire #1
Diameter?" and wait for user input. Upon input and termination with <RET>
input routine will increment and prompt with Tire #2. This will continue
until it reaches a count of 100 or the first character is a <RET>. Valid
inputs are 3X where X is 0 thru 9, Space, 1/8,1/4,3/8,1/2,5/8,3/4,7/8.
Note: 3X<RET> would be a valid input.
When either of the above 2 conditions occur, go to input routine 2
2. Input routine 2 for Front and Rear Stagger value. This input routine
will prompt for 2 inputs.
"Input Front Stagger:" User inputs 1 1/2<RET>. Upon receiving a <RET> program
will output
"Input Rear Stagger:" User inputs 2<RET>. Upon receiving a <RET> program will
go to conversion routine.
3. Conversion routine 1 will take all stored values from Input routine 1 and
convert to whole numbers and decimals.
4. Conversion routine 2 will take stored values form input routine 2 and
convert to whole number and decimals. It will also compare Rear stagger
to Front stagger and store higher value in location HIGH, store other value
in LOW.
5A. Comparison routine will search stored values from conversion routine
locating smallest value and store in LEFT. Also search conversion routine
for largest value and store in Large.
LEFT = 35.125
+ HIGH = 2.00
______________
RIGHT = 37.125
Search conversion routine for value 37.125 (RIGHT) if equal or greater
than store pointer, look-up HIGH (Rear Stagger), look-up Tire # for Left
side, look-up Tire # from pointer (Right side), and store all 3 values.
Search conversion routine for next higher value and use this value for LEFT.
Calculate a new RIGHT...and
Repeat above for all inputs storing in sequencal locations. When all inputs
have been stored and reached the value stored in LARGE.
Then compare LEFT with remaining inputs. Store highest value first, until
all remaining inputs have been stored.
5B Read the first stored Right value and write it in LARGE, than go to input
routine 2 location LOW then take
LEFT = 35.125
+ LOW = 1.50
______________
RIGHT = 36.625
Search conversion routine for value 36.625 (RIGHT) if equal or greater
than store pointer, look-up LOW (Front Stagger), look-up Tire # for Left
side, look-up Tire # from pointer (Right side), and store all 3 values.
Search conversion routine for next higher value and use this value for LEFT.
Calculate a new RIGHT...and
Repeat above for all inputs storing in sequencal locations. When all inputs
have been stored and reached the value stored in LARGE.
Then compare LEFT with remaining inputs. Store highest value first, until
all remaining inputs have been stored.
6. Output routine, take values stored during conversion routine and output using
the following format. Note: several different look-ups will be required to
generate this format.
Stagger Tire numbers Diameter
Left Right Left Right
______________________________________________________________
Front S = 1 5/8 5 2 35 1/8 36 3/4
Rear S = 2 3 1 34 7/8 36 7/8
Remain S = 1/2 4 6 36 1/8 36 5/8
Thoughts
________
I believe this approach is missing some additional optimization.
Example:
If you have a situation of more stagger then needed, it might be better
to save the bigger Right sides and use with larger LEFT sides when you
go to do step 5B.
Or
List out all the stagger values from High to Low then cut them in half
and use the first half as the higher stagger tires(in example Rear), and
the second half as the lower stagger(in example Front).
