Best Way to make uniform crushed glass at home
I obtained an abrasive blaster and I decided to use crushed glass as the media. I have a steady supply of beer an wine bottles that I can crush but have a slight problem.
I am currently useing a capped steel pipe and a baseball bat to crush the glass. The results are anywhere from large quarter sized chunks to dust.
I want to have crushed glass roughly uniform in size as well as to be able to make larger or smaller sizes depending on the application (rust, paint, etching, etc).
Does anyone know of a way a DIYer could make a uniform crushed glass abrasive to use in a blaster?
