Flux paste applicator gun

[Luciano] didn’t want to drop a lot of cash into a flux and solder paste applicator so he built his own for about $5. He re-purposed a hot glue gun which you can usually find at a dollar store. After removing the heating element he inserted the body of a syringe. The plunger has been modified to use a knitting needle inside of some plastic tubing. After taking the picture above he made an improvement by adding a milliliter scale to the plunger, allowing you to meter out the paste and also gauge how much remains.

    Next time I need one, I think I’ll try this before spending more money than needed.

    I modified a glue gun in the same manor to extrude friendly plastic from a reservoir when you pull the trigger.

    I like the idea of re-purposing glue guns.

    Now that’s clever!

    I’ve got this little bottle with a brush fixed to the cap that also works great…

    I think the little bottle brushes work a little better if you trim them down some

    Dunno why but at first I thought it read ‘Flux paste capacitor gun.’

    isn’t it a bit BIG?

    >>isn’t it a bit BIG?
    The tip size looks very appropriate.
    The modified glue gun size seems good.
    The only negative that Eric states, is the requirement to disassemble the gun in order to refill it.

    I wonder what could be done with the “scrap” is the heating element…?

    im pretty sure i’ve seen a hot glue gun at dollar tree before..
    but even more useful was a box of liek 1000 pins or more. for a buck. those, i stuck through my face.
    i wish i could solder a point smaller than a BB.

    Use some mineral oil/cracked oil fog juice and make the heating element into a fog machine.

    why not just use a stick of hot glue for the new plunger? it’s the right size, it’s easy enough to shape the end to fit the plunger… heck you could melt the end onto the plunger.

  14. draeath says:

    The glue isn’t sturdy enough. When you squeeze out a measured amount, you find you got less than you thought because the glue stick compressed some of the distance.

    For the plunger on my modified glue gun I just used a wooden doll from the hardware store. had to sand it a little to get to run smooth.

    I guess I should just post my project.
