Make a 60° angle on line $l$

We have got Line $l$ and point $P$ which is not on $l$. By using a compass and a non-graded ruler, draw a line from $P$ that makes a 60° angle with line $l$. Please help me!

Obtain $P'$ by reflection of $P$ across $\ell$; then find $M\in\ell$ such that the triangle $PP'M$ is equilateral. Then draw $g$ through $P$ orthogonal to $M\vee P$.
