Some days woodworking is not too far off from skateboarding. You can spend a lot of time working on the same thing just for it to fail in the end, just like trying a trick for hours without landing it. It can break you down mentally. All you can do is move on to something new and revisit it later hoping that next time it will work out. Take a deep breath and try again at another time... And just like skateboarding, I F'ing love it no matter how badly it beats me down!
One of my favourite decks of all time. I've considered getting the Zipper head as a tattoo as it represents that feeling of frustration and stress so well. It's either that or the Santa Cruz screaming hand... but that's a bit of a cliche.
I'm lucky enough to have a used and an unused jay Adams tribute Zipper head on @zflexskateboards I did have another purple one but I gave that away as a gift.
