Introduction: Soldering Fume Extractor Arm
Hi everyone, this is my first Instructable so please let me know if anything should be changed :)
So i decided it was time to update my ghetto helping hand work station and decided to go with the coolant hose style but that left me with a problem of having no fume extractor handy, a quick search showed nothing like this for a fan so here is my take on it.
Thing you will need:
Flexible coolant hose (2 if you want the arm to be longer, i bought 12 :D)
Fan (I used a 12v cpu fan)
DC connector (Optional)
drill bit (i used 11/64 but any size around there should work as long as its larger than the wires and smaller than the screw head)
screw driver or bit
Step 1: Remove the Ends
Simple as that you want to remove the ends on the hose
Step 2: Drilling
I used a vise to hold the parts while i drilled them to make things easier. You will want to go at an angle for the hose and avoid going to low or high, drill two holes at opposite sides. For the nozzle you will want to drill straight in then raise the drill to elongate the hole as seen.
Step 3: Running the Wire
I didn't take any photos for this process but if your not using a fan connector like i did it would be a lot easier to run from the top to the nozzle rather than the other way around like i did. You will also want to solder on a DC connector at this point if you plan on using one.
Ive checked and even with maximum bend there is plenty of space left inside the hose.
Step 4: Attach the Fan
I simply used a screw in one of the mounting holes to attach the fan, just make sure the screw isnt so long that it will hit the wire at the end of the nozzle. As you can see i needed to drill out out the hole in front to access the screw behind.
Step 5: Mounting
I conveniently have a shelve above my workstation that i was able to attach this to but any surface you can screw into should work. You could even use the threaded valve to attach it if you wanted.
Step 6: Finally Powering It
I use my variable power supply on my soldering station but any 9-12v power adapter should work as long as it can provide enough power for start up and also make sure the voltage doesn't float too high over 12v while running or it could ruin the fan.
Enjoy not inhaling toxic fumes :)
