Ok, so, I have a Reynolds 520 butted frame and I had an aluminum seat post. I had the old seized up seat post issue. I tried everything and ended up having to attempt the frightening and cringe inducing cut-the-top-of-the-seatpost-off-and-try-to-hacksaw-down-the-center-to-free-up-a-chunk move. All was going well till I brought my bike to my parents house for the weekend to use some tools and (hopefully) go for a ride with my folks. Well, long story short, my dad went ahead (against my STRONG advice not to, btw) and used a metal cutting blade and reciprocal saw to speed up the process. In the process of this, he cut a 2 inch long gash through the seat tube about 8 inches below the top of the seat post (see Pics). My question is: Is this still rideable? I don't really feel comfortable with it for commuting (its previous use), and don't like the idea of water being able to get in through the gash and get to my frame/bb housing.
Thanks BF Mech's! Your the best!
