That little dremel tool can do some things,many little bits ect.that could be used in all sorts of ways.You get good enough with it and a steady hand pick the right bits you could do some shaping,roughing out of a stock.Keep in mind when power tools get away from you they tend to make a mess of things.The sanding attachments on the multi tool can help along with sanding down a stock after its roughed out.Nothing beats doing things by hand and sooner or later you must to get things as close to perfect as possible.Keep in mind I'm no expert in gun building but know my way around wood working tools and have in the past had to over come injury and adapt tools to suit my needs,trial and error.Seems some would shout blasfamy for using power tools for some tasks but when your health doesn't allow you to enjoy your hobbies you gotta do what you gotta do.
