Building My Own Focusing Rails

I have always enjoyed photography in general but as my experience grow, I started to want to explore more specialized niches within photography. Macrophotography specifically for the purpose of archiving, product photography, biological (insect and plant) photography is where I want to start exploring. If you too are interested in this type of photography you will quickly learn that the biggest challenge with this type of photography is shallow depth of field you have when shooting at such a small scale. This is how I am overcoming that.
