I have the MaxPower PivoTrim weed trimmer head because the spool type trimmer heads always get tangled. The MaxPower PivoTrim head makes replacing trimmer line super easy.

When I ran out of the trimmer line that came with the head, I bought a spool of new trimmer line. Unfortunately, when you cut some trimmer line and install it in the head, the line curves up or down instead of pointing straight out. So, I found a way to straighten the trimmer line. Below is a picture of the line straightened (left) and before it was straightened (right).

To straighten the line, I cut the line to length, stapled each end down to a piece of 2×4, took a heat gun and carefully heat up the plastic line to soften it and cause it to take on a new shape.

Then, I folded the straightened line in half and stapled each end down to the 2×4 and heat up the folded end so that it would remember that position.

The end result is trimmer lines that are straight and cut weeds better. Note, you may have better performance if you remove the plastic guard on the trimmer shaft.
