I saw a tutorial online somewhere that showed how to modify a glue gun. It wasn't that good of a mod, and since I needed a precision glue applicator, i figured i'd make my first Instructable while getting what I needed. It was actually quite a simple mod, only took about half an hour start to finish, and cost me a whole dollar for the glue gun (gotta love dollar stores).
Step 1: Disassemble Glue Gun
To start off I unscrewed to glue gun, there were 4 screws. Easy enough...then i also dismantled a Bic lighter discarding all but the little nipple the gas comes out from. At this point i took my trusty knife and cut the glue gun casing at the handle so tha it could be inverted for a pen like grip(see photo)
after carving out a small piece of the plastic to allow for the joining of the pieces i used my low wattage soldering iron to fuse together the parts in the new positions.(if you dont have a low wattage soldering iron you can use a lighter but this is not advisable because burning plastic can be very dangerous.)
