what has been your biggest mistake when building a bike

[Waxintaxin]

stripping a nos gold set of DX in caustic , leaving it as it wasnt getting the anno of , then realising the alloy was being eaten from under the "paint "
watching all the pins falling out and ruining a nos set of dx
although it did answer the question as to the finnish of DX

paul from jos conways cracked a robinson head tube putting cups in 
       my m8 andy bibby did a wheelie like steve strong did with the front wheel
       missing cool till he came down on his face

My biggest mistake was selling all of my oldschool's when I split up with the miss's in 2005! And what make's it worse is looking at all of your sweet rides and feeling like i'm missing out!
