Reverse wing plan
 

I'm sure this has been asked before, but I couldn't find it using the search engine;

What is the best "stuff" to apply to the plan sheet for reading the reverse wing plan (without too much mess)?

Happy Holidays,

Roger, Ask around and see if someone you know has acces to a "light table". It is used in graphic arts. If not, see if you can find a glass top table that you can set a small lamp under. Then you can see through the plans and trace them with a pencil. And NO messy oils!

Reverse Plans...
 

It's messy, but it's how it was done years ago:

Rub some cooking oil (pick a brand, don't matter) on the back of the plans. The lines on the front will show through the paper, and the wax paper or plastic wrap you use to cover the plans to build upon will not stick.

Some people spray WD-40 on the plan. But I just spread some tracing paper over the original, turn on the radio, and redraw it with pencil and straightedge. Not really a big deal to do.

The nice thing about tracing on the back (using the glass table technique) is that you don't have to worry about the paper slipping.

And when using the light table method, you don't really have to redraw the whole darn thing. Just tick marks to line up the leading edge/spar locations/trailing edge/rib location is enough unless the wing is a more complex shape.

Saves you some time on simple structures.

Excuse my ignorance, but I'm just curious as to when you would need to reverse the plans?

Some plans only include half a wing.

Your local print shop should be able to make a reverse copy for a couple of bucks.
