Lens-board Mark III for the Kodak Aero Lens

Thank you for purchasing the JoLo lens board to create your very exclusive

Please read this carefully, before even thinking of starting right away!

On the lens board you'll find the Allen hex key taped on the back of

the lens board.

First of all tear off the tape and use the Allen key to turn the hex

screw on top of the JoLo lens board until it does no more extrude

inside the thread.

1) Cover the front and rear lens while working on the lens.

2) Remove or cover the ground glass of your camera to avoid breaking the glass.

Clean your Aero lens thread thoroughly with a brush and if necessary some lighter gasoline.

Make sure nothing of the liquid can enter the inner lens.

These objectives are more than 50 years old. Therefore, you may check the thread carefully

for imperfections. If you do find imperfections use a sharp knife or even better a special file

to repair the thread. (fig 2) Always use a magnifier!

Turn the fixing screw (fig 7) a bit anti clockwise so that it does not protrude on the inner

thread of the lens board. (fig 1)

Try the lens board if it runs easily on the lens thread (fig1)

If it does not, please turn it back again and try to find the cause of the problem.

force the lens board by turning it too tight. The lens board might not loosen again without

seriously damaging the thread and thus making the lens unusable.

The lens board should be positioned so that its rear edge just covers the lens threads,

without allowing any threads to protrude backwards. (Fig 8)

Now search for the right position so that the marking point of the diaphragm points up and

lies in a straight line with the fixing screw. Fig. 5

10)

Fix this position by turning the hex screw tight with a hex wrench. Fig.6

Having found that location, turn the lock to the right to secure the front standard firmly.
