Hi Folks,does anyone make and sell a planer blade sharpening jig? I have a 12" & a 13" lunchbox planer and a 6&1/8" joiner. I am willing to pay or trade with someone that is willing to make the jig(s) that I need to be able to sharpen these blades. I have not been able to find anyone local that can sharpen them and sending them out is costly enough that I can buy new ones for just a couple of dollars more. Any help would be greatly appreciated. Thanks, Steve
