--> Tailwind-List message posted by: Hopperdhh@aol.com

Fellow tailwind enthusiasts:

I have  written a template calculating program which is posted at  
metalgeek.com.   There is also a derivation of the math  involved.  Best of all
it is 
completely free.  Scroll down about 1/3  of the way and click on "Dan Hopper's

TUBEFIT Program" on the left side of the  screen.  Its a very short and simple

program that you can download and run  offline.

This program was originally written for building race car roll  cages, but it 
should apply very well to building metal tube  fuselages.

There are a number of neat features about the program.   You should be able 
to calculate the length and angles (center-to-center on the  longerons) of the

tube needed from your plans.  You can then use the  templates that you print 
out to cut a piece of tubing that is exactly right, on  both ends, the first 
try.  You can also use it to fit more than one tube at  a time, such as occurs

at a cluster.

This program has been a hobby type  project of mine for a number of years.  
I'd like to see someone put it to  good use.

Regards,

Dan Hopper
