The Cheapest Pneumatic Cylinder Ever Possible! Less Than $2

Hi everyone,

In this Instructable We'll be showing you How to build the Cheapest and the most Efficient Pneumatic linear actuator.

Why was this Pneumatic Actuator created?

We were actually forced to find a cheap way to build a pneumatic actuator; The price of the actuators were too pricey for us to buy; It was a real deterrent to our progress. After a long struggle and several prototypes, We removed the need for costly tools and O Ring (replaced it with the rubber), so that it can be easily made by anyone in just 15min. The total cost for one cylinder is less than $2.

The given price is just the average price throughout the world

This costed us just 16 cents only!

Testing the Pneumatic Cylinder:

Materials:

• Syringe x2 ( 2ml - 4ml )
• Metal rod (about 3mm)
• Small washer

Consumables:

• Rubber based adhesive
• Super glue

Tools:

• Wire cutter or hobby knife
• Thin screwdriver
  

• Separate all the parts of the syringe
• Remove the nozzle of one syringe
• Make a hole near the end of the other syringe through the inside ( Yes, from the inside)
• Glue the nozzle to the hole using super glue
• Use the adhesive to seal it

• Fix one rubber part to the metal rod using Super glue
• And also slide the washer into it
• Make a hole in the other rubber and insert it into the rod
• The rubber's cupped side should face away from the cylinder's body
• This will act as the o ring
• Now insert this and fix it using Super glue

Now your super cheap and efficient pneumatic cylinder is ready
