[Shop-talk] Making a hole

[John T. Blair]

I'm working on a project and using a 6"x4"x2"  "plastic" 
project/experimenters box from Radio Shack.  I'm trying to install 
some mini DB9 connectors in the ends of the box.

I go down into my SHOP, and clamp the box in the vise.

After I scribe when the connector should go I've tried 2 methods for 
making the hole:

1. The first was to drill a hole to insert a saw into,  and then use 
a coping saw to cut it the hole.  This was very time consuming and 
tough on the box.  In fact I broke several.

2. The current method is to use a circular saw blade on my dremil 
tool, similar to:

     Once the hole is rough cut, I use a triangular file to clean it 
up and size the hole so the DB9 connector fits.

I was wondering if anyone had a better idea of how to do this?
