Start teleporting whenever, but I do it once I got my gun pack-a-punched.
What you need to do is throw grenades near the end of a wave, get a crawler ( zombie with no legs, drags itself with it's arms and is really slow ). Let that chase you around the map while you hook up the pads. Make sure you have a crawler left at the end of each round so you can resupply.
Juggernaut should be bought before you upgrade your weapon.
Do what you're doing, run around and kill them. Throw nades and get a crawler, don't kill it and just run around hooking up the pads. Once you're ready, kill it and wait for the zombies to start coming. Chill on the tele-pad until they get close to you and then teleport. Once up there buy those grenades on the left wall and throw them down at the zombies, I can easily buy 3/4 loads of grenades before I get teleported back.
Wait for the zombies to come to you and start to run around the map again, rinse and repeat.
