An alternate method is to use a magic spell - the demon eyes he spawns almost always drop a mana pickup, allowing you to spam the heck out of whatever magic you have. A platform grid definitely helps, 20-30 blocks wide with about five or six blocks between. I have an ice block wand I found in a chest around depth 750, so I can throw up platform grids anywhere I want whenever I want. Or quick ice walls to interrupt adds.
