You need a friend to help.........then you only have a 50% chance of disaster occuring. The mistake was coffee tho....next time try your beer of choice.....drink two then do.

 

And Im guilty too........I have ruined even the most routine........my most commical tho.......I was fender mounting turn signals on my softail custom......I had to drill the holes in the fenders to mount the lights where I wanted them......no beer either mind you......I drilled the first no problem.....I drilled the seccond and the next day went to HD for a seccond new tire of the season as I drilled a hole clean through the top sidewall.........Im a bone head too....happens to most at some point....sure wudda felt better about it with a few beers in me tho.
