I was put off buying one of these by the high prices, so I made one. Interesting little project. I don’t use it a lot, but when I need to drill very small holes, e.g. for clockmaking, the extra “feel” is invaluable. It only takes a few seconds to pop it into place, so much more convenient than swapping over to the standard Myford lever feed device (which I also have). I’ve never felt that lack of rigidity was an issue.
