WILLIE CARSON: Hi! My name is Willie. I'm from Carson Saw Shop here in Eugene, Oregon and I've been sharpening tools here for 25 to 30 years and I'm here with Expert Village today. This is an acme grinder this is one the most useful tools in the shop. It's been around for a long time and lots of [INDISCERNIBLE] have been sharpened. This came out before carbide saws came out but still has application for them as well as a lot of other tools. One thing about it is it has a lot of versatility you can switch wheels very quickly and it has a lot of different apparatuses that can bolt on to the machine to help you do things. It's got things that clip on here for doing circular saws. You can shape and use all different shapes and sizes of wheels according to what applications you have and so you usually have a shelf full of stuff that you've already pre-dressed so you can get the right wheel and it's pretty close to shape already so just using one of these dressing wheels you can cut it back to shape real quickly. Once in a while you can even take a wheel and sandblast it to get it cutting again. If one of these won't roll the particles off and leave it sharp enough, so there are all kinds of little tricks, you can put soap on your wheels to--like ivory soap to help them cut better too.
