I saw a bottle opener like this somewhere and decided to make my own. Notice pac man has two teeth, those are there because bottle caps are much harder then ghost.
Step 1: What I used
As far as tools go its rather meager. you can get by with less then I used certainly, just depends on how much elbow grease you want to use.
Jigsaw-make sure its a very robust jig saw that can handle cutting metal.
A round object to trace around- I used an old funnel
Trusty old brace-this thing never needs new batteries
1/8" twist bit
safety glasses- most important tool I use.
Metal cutting jigsaw blades- I used some from Bosch that I highly recommend
paint marker- these are much better then soap stone for marking steel as the paint doesnt wipe off.
scrap steel- this is 3/16 hot rolled plate, I think
Step 2: Lay out your pacman
I supended the funnel and traced around it with my paint marker. I used a corner so I could have an easier time of cutting out the shape and by doing so it gave me a flat reference point to start pacmans mouth. Pac-mans mouth is little more then a wedge easily drawn in and his eye is a dot. So I added the mouth and eye, but in the mouth I left 2 teeth to help open the bottle better. I center punched the eye so my drill bit wouldnt wonder.
Step 3: Drill the eye, sounds painful
I drilled out the center punched area with a 1/8th drill bit then widened the hole with a unibit. Unibits are great because they will stay n the same spot without widening the hole off your original mark. Be sure to run the bit on the opposite side to remove any left over burr.
