Stating this another way:
1. Precision alignment is a necessity. "Close enough" is a metaphor that means "not good enough" in the final analysis. :wink:
2. Jigs and fine adjustment of said jigs or saw is a necessity.
3. When precision like this becomes a necessity, it is much easier to drill on the lathe than on a DP, at least until enough precision experience on the DP is gained.
4. Use a drive center (

Turn one end round for about an inch in length, and then add a chuck to the headstock - chuck it from the head stock end. Drill from the tail stock end so that the drill bit is centered on the initial mounting hole point from that end. Viola a precision centered hole.
5. Don't get discouraged. It may take two or three blanks before you gain the experience needed. But if you learn it quicker, GREAT! However, once mastered, the experience will make you VERY productive and happy. It will be almost like learning to read for the first time! :biggrin:
Editing in - There are two groups of people who do this well:
1. Naturally gifted people who have the eye and hands of an artist and do this as a second nature. In their minds eye, they can see alignment of the wood and the alignment on the DP and lathe naturally. Gifted! And some here are this!
2. Those with experience, practice, persistence and JIGS and precise machines. Jigs, precision alignment ability of machines and clamps help make the playing field more level - and moves normal people up several levels to (at least close to) that of the realm of the gifted.
