I need to disassemble my entire bike so that I can have the frame and forks painted. While I have a ton of auto tools, there are obviously a few things that I can't disassemble / reassemble without actual "bike" tools. Can you guys suggest the things I'd need that auto tools can't cover? I know the chain whip and cassette locking tools are a couple...
Also, would it just be better to just get a kit? I only have about $100 to spend though and it seems like the Spin Doctor Team 33 tool kit would have it all, or maybe the Spin Doctor Essential tool kit?
You don't need a chain whip and cassette lockring tools to be able to paint your frame and forks.
You'll need a chain breaker, the appropriate bottom bracket wrench, and depending on how old your steer tube/forks are, you may need a headset removal tool. The rest can be done with standard tools--sockets, ratchets, open/box-end wrenches, allen wrenches and screwdrivers.
Depending on what type of componentry, you may need or want a bottom bracket cup removal tool, some headset wrenches perhaps, headset cup/crown race removal and installation tools as required. Some folks do not remove the BB/headset cups for painting and some do.
Like jpr95 said, your existing tools will go a long way towards detail stripping your bike. And headset cup/crown race tools can be fabricated at home in you want to get that involved. The typical metric hex key set and a Torx key set are necessities for most bikes.
You'll definitely 'want' that cassette lockring tool and chain whip for future home repairs anyway. Is it possible for a man to have too many tools? Nah! Never!
If you have carbon fiber component parts or are somewhat ham-fisted with wrenches, a torque wrench will be an often used tool. I do not consider one an absolute necessity for the very experienced wrench turner, but it's still a nice reference to have and use. The torque wrench is dirt cheap compared to the cracking noise your carbon seat tube just made...
