Planing Jointer Table

This is the infeed table of a wood jointer. It is 47"x21". The trailing edge of the table had a steel insert riveted in place and so I was unable to use a flat-tool for cast iron. Instead, I used a shear-tool for steel which does not work as well for cast iron. The underside was planed first by shimming the table so it remained stress-free. This gave the table a firm bearing when planing the top side. For the top, after setting up I rough planed the surface using a large radius tool with a trailing flat. Depth of cut was about 0.020" with a feed rate of 0.125" I did not have a camera for the roughing, so this video begins with the results of the roughing pass. Note that I did not want to use my good shear-tool on cast iron. The one I used had been relieved each side of center so that cutting took place only with the central half-inch of the tool. Edit: Looking at this later I wondered how it was held down. I'm probably not the only one. It appears that "fingers" were not used. I see jacks and I seem to remember that the table rested on parallels and was held down using the table's mounting bolt holes. I do not remember specifically how, but I think I screwed in a few bolts and pulled down from under the table - reaching underneath to tighten. It would not have just sat held down by its own weight. The tool would have made it try to roll over the end stops. Rees Acheson
