Spars

Re: Spars

Hank, most people use CAD or CAM now...tim

We had a machine like what you are talking about called a "Cardex" when I worked for the Navy on the A-6. We used it to input all the data needed for a CNC machine to duplicate just about anything. NOT a cheap machine and I don't have access to one any more (not that my rich Uncle would have ever let me do my own project on it when I DID have access!)

Once we have the drawings and can see the tolerances making a drawing will be pretty easy (if those tolerances aren't too tight). Wouldn't the tolerances for the tandem bird spars be the same as the side by side ones? Anyone have the drawings for any of the other planes?

Forrest used to say most parts of a "T" were + or - 1/8". If that is true of spars I can measure that on my spars with a steel ruler. Somehow I think the hole spacing is a "bit" tighter on the spars.

Well, the A-6 has been gone for quite a while now. I left the Navy quite a while ago too. Our CAD system was on 8" floppy drives!!! They held a WHOPPING 1.25 Meg each! We didn't think we had enough drawings to fill one up when we started. That didn't last as long as the training class for the software. Remember, this was PRE DOS!
