Dremel type tools , are excellent tools , ya' just have to learn where they are appropriate , and how to use them. I don't use brand name Dremel tools , 'cause they're too expensive for my tastes. I destroyed perhaps 4 of them over 40 yrs., and finally local hardware stores began handling them for $30 or less. This has allowed me to have 4 of them hanging on my bench , w/ different bits I use the most. Time has shown me , that the cheap hardware store tools , last just as long as the expensive ones. Many folks say , power tools of this type should never be used to work on m/l's , but the way I see it , If a tool saves me shop time , and the end result , is as good,or better as using an old fashioned tool , I'll take it. For instance , Installing most butt plates to perfection , takes about an hour , employing a 1/4 " 36K RPM die grinder , and a dremel type tool for the fine work. These comments are not spoken, to antagonize the purists among us , but to encourage folks that can benefit from using a modern tool. .........oldwood
