Some may ask why is this tut when there is the easier one wit the iron from digikey. Well the answer is, digikey doesn't ship to europe and all I managed to find here is this type of desoldering irons. One more thing is that this conversion is totaly reversible, you can use your desoldering iron to desolder in just one minute - no modifications to the stock irons are made.
What you will need for this tutorial
1. Desoldering iron 40W with a built-in vaccume pump - $ 6
2. One bottle cap
3. One screw 5x20mm
4. One fishtank air pump - $ 6
5. 1m (3ft) flexible hose-pipe - $ 0,3
6. 1cm of hard hose-pipe
7. 1m (3ft) thin copper wire
You will need a drill machine and 2,7 or 3mm drill bit
so let's start...
Step 1: The iron
It is 40W and you can find the same at ebay.
First we must disassemble our desoldering iron. It has a body, a yellow cylinder, a spring and a piston.
The spring and the piston we don't need, so we pack them together, in case we deceide to use the iron as it is meant to be used.
Step 2: The cap
Now we need a bottle cap. These caps are used with many bottles, mainly bottles for chemicals or from the drugstore.
I was wondering how to put the hose from the air pump into the yellow cylinder, when I found that this cap fits perfectly to it.
Step 3: The screw
This is easier to find I think. We need 5mm screw, that is about 20mm long.
The idea is to drill a hole through it. I try drilling with a 2mm bit, but I broke it, so I dill a hole with a 2,7mm - no troubles this time.
