I would suggest that if you plan to engrave metal with text or other fine lines that you try to find a spring loaded floating engraving spindle. They keep the depth of cut at an exact depth for the entire job. Doing letters, a difference of only a few thousandths of an inch in depth of cut, when using a "V" type engraving tool will make the lettering look very bad. You can get a constant depth on a 5000 pound bed mill pretty easily, but on a home made machine, built from aluminum and Ace hardware parts, it's not so easy. I have made a couple of non floating engraving spindles into floating ones pretty easily. Also, I used a small laminate router on my machine for about a week before it was totally shot. Problem is it was designed to run for 2 minutes at a time, not an hour or more that will be required when doing engraving jobs. The bearings get hot and then the plastic that holds them get soft. Now you have a piece of crap spindle with an 1/8 inch end play which is not suitable for engraving fine lines, much less anything else.
