Review on Woodstock W1210A Polycarbonate Jointer Pal - Black, Lightweight at 1.4 ounces by Joseph Campbell

This tool was able to install knives on a Central Machinery 6 inch jointer. If I didn't have it, it would take a LOT more effort to get the knives right. , I had to do a few knife setting cycles and then test to make sure all 3 were set to the same depth of cut across the width of the jointer. But the main thing is to pay attention to the marker lines and their placement relative to the blade. With one knife, I had to manually adjust one end to set it to the correct height. But the time from start to finish installing the knives took just over an hour; Without this tool or similar, adjusting the knives to the correct position would take much longer.
