The Leica Mount for a CP 4500

• IMPORTANT NOTES
• Nothing in this presentation is drawn to scale
• If your eyepiece is narrower in diameter than my
  20-60 (about 50mm) this gadget may need extra
  felt (see step 8)
• If your eyepiece is wider in diameter the
  principle will remain the same, but you will need
  different sized PVC pieces.
• You can use the scope, but not the zoom, using
  this set up.

The Tube

Cap Piece
4
Other Bits

• 4 Small (about 4G or 2.5mm) 10-12mm self tapping
  screws
• 28-37 step up ring
• 1 piece of sticky backed felt. The type you
  stick under vases, etc to stop them scratching
  furniture
• A small sanding disc or drum is very useful.

5
First Step

• Cut the top off the Cap
• This leaves a hole in the centre of the cap
  piece that is perfectly centred and very close to
  the size required to fit the camera lens in
• 2. Smooth down the top of the cap (I used a
  sanding disc on my drill to do this)

6
Second Step

• Smooth down the rims of the tube with a piece of
  sandpaper
• Sand down the exterior of the tube to make it a
  tight fit inside the cap piece. It needs to be
  a tight fit but one that can separated by hand
• (I used a sanding disc on my drill to do this)

7
Third Step

• Sand or file the hole in the cap piece so that
  the camera lens will fit in with about 1.5 mm
  free all round
• The picture shows the centre hole with thestep
  up ring already mounted but you get the idea.
  If the hole is too large it is difficult to
  attach the step up ring.I used a small model
  making sanding drum on my drill to do this

8
Fourth Step

• Rebate a small ledge around the hole on the
  inside of the cap piece.
• I used a small sanding drum to do this. This is
  done to make the ring sit more securely and to
  raise its bottom edge up from the lens.Dont
  take too much away. It only needs to be 2 mm at
  the most
• I cannot show a photo of this phase.

Fifth Step
Drill Here
Drill Here

• Drill 4 x 3mm holes into the angles of the steup
  up ring.
• Make sure the holes are drilled at an angle so
  the screws will go into the PVC at an angle
• Hold the step up ring in place and drill 1mm
  guide holes into the cap piece
• Screw the step up ring to the cap piece.

10
Sixth Step

• Grind down the tops of the screws inside the cap
  piece
• 2. Grind down any pointy bits from the screws
  that poked through
• I used a small grinding wheel on my Dremel

11
Seventh Step

• Use a small brush and vacuum to clean away all
  PVC and metal dust

12
Eighth Step

• Cut a strip of felt about 1cm wide and 6 cm long.
• Stick it along the inside of the tub and fold
  back over the outside.
• This provides the grip when you slide the tube
  over the eyepiece

This is now the BOTTOM of the tube
13
Ninth Step

• Slide the tube over the scope eyepiece. With the
  felt in place in should be a tight fit,but you
  should be able to remove the tube easily.
• Attach the cap piece to the camera
• Slide the cap over the tube. Make sure the cap
  is on as far as it can go. If the outside of
  the tube has been sanded as per step 2 the cap
  should be hard against the tube.
