got to say the bondo flipper takes some imagination......seriously new flippers are cheap..

just a tip ....soldering is like welding ...if the parts and the wire are dirty the solder joint sucks same as welding, if you don't take the time to clean the parts to be soldered you will never be good at it. So on the tab it is a good idea to use a solder sucker to get all the excess old solder off then clean it with alcohol and maybe a wire brush if its really bad then apply solder flux (a necessatiy to get the part to tin) and re-tim the tab. Usually older pinball wire is very hard to get tinned cut the old wire that has solder residue on it off and restrip to get new straight wire ...dip the wire in flux and then tin .....then stick the wire through the hole in the tab and wrap it around with needle nose pliers. Make sure your soldering iron tip is tinned and clean it often so its shiny like chrome then lay it across the tab and the wire at the same time and flow solder into it for approx 5 seconds ....practise and you will get better

wow soldering on an alkaline battery is like playing with an M80 ...that dude was either stupid or lucky or both

when I was in the navy one of the guys was trying to fix a personal radio by doing this...needless to say the battery exploded and left his face disfigured for life

that is one ugly hack

i second that thought
