Not being possessed with that most desirable of tools, viz., a lathe, and finding it impossible to procure a suitable tool for our purpose at a reasonable price, we decided to make a machine with which we could bore any'size holes necessary for our purpose, so we proceeded thus: --Having a small breast drill (which fit my brother...
