Bike mount
and
Overhead Projector Telescope

2008
 

  I made a mount and telescope of valueless
materials.

The mount is made of a bike front.

For the telescope I did use the lens and focuser of an overhead projector.

   

 

 

 

 

 

These part of a bike you will need..

Two of these parts are needed

 

 

     
   

The Bracket will be part of the telescope.

     
   

I saw a  piece of the tube and replaced the bearing cups.

 

     
   

A part of the handlebar is used. It will be the declination axis.
 

     
   

Here you see the second demolished bike.

These parts will be the RA-axis.

 

     
   

The two parts are connected.

Now it's possible to move the telescope horizontally and vertically.

     
   

A piece of wood, cut off by 53 degrees.
The groove is for centering the RA-shaft.

 

     
   

The shaft assembled on the wooden block.

     
   

The mount is ready

     
   

You see the brake on the declination shaft

     
   

 

You see the brake on the RA shaft.

     
   

The mount.

     
   

The telescope is made of Overhead Projector  parts. You see the lens (85mm f250) and the focuser.

The eyepiese holder is a photo film holder.

     
   

I replaced the focuser for a better one.

     
   

Here you see the mount and telescope.

I worked 12 hours on it!
