How to blow up blueprints to full size?
No Quarter
ultralight from a kind newsgroup surfer, Dave Mills. Thanks Dave!
I'd like to be able to blow the prints up to full size for making templates
and wondered if anyone out there has an idea for anything like this. I have
envisioned the following:
Scan in the blue prints with my handy dandy scanner.
Then, blow the prints up with a paint program to correct scale.
Use a program (that is hopefully out there) to print out the prints on
multiple pages so I could tape them together.
Anyone else got a great idea?

Take your plans to an office supply store, they usually have the equipment
to make very large copies of any prints. I believe that they are called
"vellums" or originals. I did that when I built my own house. Price was
cheap. Now if I could just afford that Buckeye Dm 582 :-)

The general idea is to copy, by hand, the design on to sheets of
plywood in full scale (time consuming and frustrating to start, but
once you get the hang of it...). You would copy the plans from ,
above, side, front, rear.
Then the idea is to be able to set nails into the plywood to hold your
parts together, better assuring a proper fit over all.
For more info, any good book from the library on wooden boat building
will show you the technique.
It is a long process, but great results...at least for boats

Many programs allow yo to "Tile" your drawings, but my great idea is to
remember there are still people in the world wo write with a pencil.
You might try to make a loft floor (since you will need it to lay out your
papers anyway.
Mark the floor with grids, and do a direct PENCIL blow-up on the X-Y
grids.
This is a very old method, but it still works.
Good luck.

that error is introduced because the line thickness increases substantially
the larger you go. It would be really great if you (assuming that you are
the builder) could get a table of offsets for this design, then you could
loft it properly with a very small degree of error. If you *do* end up doing
mechanical enlargement via projector, it's very important to always stay
exactly in the middle of the line while tracing.

This may have some severe linearity problems, but it might work.
Make sure to measure all critical dimensions. For general fuselage
contours and wing/tail outlines this should work. Wing ribs you
probably want to replot from airfoil data if available.
One way to check it: photocopy a piece of good graph paper (check it
first) onto a transparency and project. Then measure the squares.
