Yeah, but I can spend an extra hour at work instead of replacing my tip and make enough to have it done 3 times professionally. The video I watched really pointed out what's lacking when doing it yourself. I'm a general contractor by trade and do a lot of wood and metal work. I need good tools to make square cuts, I'd never try to do it by hand. I can imagine how your shots would be affected if you were a few degrees off on one side of the tip vs the other. If you didn't hold the cue in the same rotation every time, you're shots would all be off.
Plus, I'm the sort of guy who would end up buying a lathe after seeing that clip! One of the cheap lathes showed up on craigslist the other day:
Like new excellent condition works excellent. Cut and paste links below to see it and use.. https://youtube.com/watch?v=9E3ZhnOsUrU&feature=share. https://youtu.be/3Blydb5kAdI

If it wasn't for many here bashing that model lathe, it would be in my basement right now.
