Sort of agree with Hank
Started with a quarter inch drill on a stand and a file.
Next was a miniature Unimat which was very useful and a great learning tool. Still the most accurate 3-Jaw chuck I have seen.
Next, a 6" Atlas which did not fit my learning curve and just did not do what I wanted.
Next was a lightly used 14x48" Clausing which I have not outgrown. Easier to use than the Atlas for small stuff and have not reached the limit of its capabilities.
Used each for several years and would not go back.
