With the one machined side down on the table, we try to clamp them down to machine the other side. The "M" written on the part indicates the to be machined side. We tried clamping from one end, but that lifted and twisted the other end. Not a good solution, both ends are supposed to be in the same plane with each other. And we couldn't clamp on the web portion, it acted like a fulcrum and also lifted the end, which would have created tapered cuts relative to the other side. We needed another plan.
