I'm planning to build my own guitar (not from scratch), and I need to know how big an undertaking this would be.

I would buy a mahogany Telecaster style body, and fit the neck, machineheads, pickups and everything else really by myself (maybe a killswitch too). My guitar tech knowledge is minimal and I was simply wondering if, with help from online tutorials, walkthroughs and advice, if I could do this or if it would be too hard.
ya if you buy a kit it'll be cool. get a cheap one to start with so you can screw around.
Jumping on dat gear sig train.
