Hi Bill,
The Lindsay templates are a good choice. Regardless of the level at which you want to engrave, you cannot even reach mediocre without properly sharpened gravers. With the Lindsay system you typically start with square blanks. It is best to have a simple bench grinder to roughly shape or taper the square blank. Then you can use a flat coarse diamond bench stone to shape the facets required for the desired tool. Then a fine diamond stone to smooth it up, and then I use two ceramic stones (one finer than the other) to hone the polish and create the heel. After you shape the blank, you usually won't need the diamond stones and will use the ceramics for repeated sharpening. If you have to reshape the tool, then the diamond stones are needed again. I also use a leather strop charged with simichrome polish to final polish my gravers. I recommend as a start that you get Lindsay's universal, detail, and one of the flat graver templates. The detail template creates the classic 90 degree graver that Lynton's video produces. It is great for shading and thin detail lines. The universal graver produces a tool that cuts main lines very nicely, has a heel that does not drag when cutting scrolls, and is very strong. The flat is useful for borders, background removal, and nick and dot borders.
Good luck,
