Recently I was working with my drill press when the motor burned out. Lacking the funds to replace it, and in the middle of a project that required one, I thought it would be fun to come up with a press built completely out of wood. Taking it further, I wanted it to house my cordless drill so that it would be completely portable and stowable.
The design incorporates a box drill guide which, by itself is useful for drilling straight holes in projects that are too large to be brought to the press, or with the addition of an extra strip of wood as a guide, it can easily be converted into a dowel hole tool, ensuring perfectly straight joints in your work without the use of a jig.
Now the measurements I used were based on an 18v Royobi cordless drill, so you may have to make some modifications in the dimensions to fit your own drill. Since drills come in all shapes and sizes, It'd be impractical to give you a 'plan' to work from. Rather, like all of my instructables, it's my intention to create a set of design rules that, if followed, will allow you the flexibility to modify it to whatever need you may have.
