Hand Roller
Keep your roller clean. Do not let glue stick to it.
A hand roller is a compound simple machine.
It is a tool that places pressure on a material.
My roller is in the shape of a cylinder. This cylinder turns around an axis.
Most of the time I use my hand roller to flatten, or spread something.
