Replying to Replacing Edges/ Base Work

Underfoot on my urbans is kinda shot base wise/edge wise and I was gonna try to replace the edge and rebuild the base just to get some practice. I googled around and didn't find much other than expensive machines and shops to take my skis to. What material is used for the base? I figure I can find ski edge material at my shop. I thought I would grind out the old/shitty material with a dremel and then work on rebuilding the base and the edge. But does anybody have any tips or pointers before I start?
