hi, been away for a bit. my bad!
so here's the needle i bought:
Ballet Sterile Stainless $ 25.60 Steel Disposable Needles F2 Regular Shank - Box/50 (from Texas Electrolysis Supply)
i experimented with it, "rigged" it up. a bit of crimping on the shaft that you put the needles in, and an old needle inside to keep the new one in the right position is what i ended up with. i got rid of the plastic tip, and have some paper or something stuffed inside to keep the needle in place.
also, online people talk about rigging the trigger mechanism to a wet sponge. I use a wet piece of rag (saltwater) in a jar lid. you pretty much open up the machine, figure out which wire runs to the contact plate, and run a new wire that goes into your sponge/rag. once i find my camera cable i can post pics, but i've got little hope for that.
it's working great. it's easier for me to do my right side, so it's pretty clear. i've been doing it about a year now, not very often. it does make red dots. maybe it's my technique of making sure they're dead. personally, i'd rather have red dots for a week than have a hair come back.
