Set of nylon gear wheels from e-bay

A radio controlled servo.

You need one of these DPDT switch (dual pole dual throw)

Switch

you will also need some plasticard a safety pin and some superglue GEL

& Kaynar Wire

Step 1

Be carefull when stripping the motor as there are some sharp parts

When you have removed the back the center spindle (made of brass) should be free to remove you will notice 2 graphite rings on the end

these need to be removed (use a pair of pliers they will just crack off). Cut off surplus metal to create the top bearing for the screen. Pictures of the finished result below.

NB be careful not yo missplace the ball bearing that sits between the spindle and the black bush shown in the picture.

Step 2

Cut a length of wire off the paper clip and using a pair of pliers twist it around the wormscrew thread and you should end up with something like shown in the picture.

You may have to do a bit of tweeking for it to run freely along the wormscrew.

Step 3

Using a small pair of wire clippers take one of the small cogs shown below and snip off the larger of the 2 cogs

now taking a drill bit a tiny bit smaller than the wormscrew make the center hole bigger so it pushes on to the wormscrew nice n snug.

Next get this cog from the set and cut off the center support to make it flat..

Attach the servo arm shown and superglue the cog onto the base of the cog and screw it through the center onto the servo.. Pictures below show the finished product

Here is a picture of the wormscrew with the cog and lever attached.

Here is the top of the wormscrew mechanism that you have removed earlier..

you will need to prepare the case from the bullet proof screen

Now using superglue gel fix the plate to the back of the housing as shown in the picture below

The silver plate you can see is there to give strength to the housing and supports the servo..

You will also need to file the front edge off the bracket as shown as this stops it binding to the screen as it raises and lowers...

Now comes the very fiddly part using the cog shown below make the center hole bigger so that the worm screw spins freely.....

Once you have done this clip off the cog part and trim as close as you can to the spindle..

Sand one of the sides so it is flat and lines up exactly to the bracket, using a soft piece of metal bend a support to fit round and glue into place

Now once dry put a small ammount of grease into the collar. Get the ball bearing you saved and place it inside the collar and push it home with a cocktail stick.
