Answer 2

Hi fabian.If the phillips head is worn out,take a hacksaw and saw a slot in it that will accomodate a flat head screwdriver.Now you can either use a tool called an Impact screw driver(Used with a hammer and has a screw thread that automatically supplies a turning motion to the screw when the tool is hit with the hammer) or you could use a normal screwdriver and apply the turning motion manually while hitting the screwdriver.Remember to apply adequate downward pressure to the screw so as not to destroy your new slot.This procedure is called shock therapy in the machining industry.Hope this is helpfull and good luck to you.

Answer 3

You know those screwdrivers that have two flat sides? Like this one:

Put it into the triangle screw so one point is straight down, touching the hollow area and the other side should be in one of the triangle's corners. When you do this, make sure you push down on your screw to relieve pressure from the screw, making it easier to turn.

When you turn the screw, make sure the screw driver STAYS IN ITS PLACE! This is important so you don't grind it or it will slip out, which will happen a lot on your first go, depending on how tight the screw is.

I hope this helps you :)
