Flattening The Benchtop

Not using a planer created a benchtop that was very uneven.  Searching on YouTube I found a great tutorial on how to use a router to flatten a Roubo Workbench.  You can see how I did it below, but the Wood Whisper's YouTube video is far superior to my tutorial below.

Wood Whisper's Tutorial for Flattening a Workbench or Large Boards



Using two pieces of sacrificial boards nailed to the sides of the benchtop as guides.  Unlike the Wood Whisper, I choose to use finish nails and secure the sacrificial boards into my benchtop as my boards weren't straight when only clamped to the side.  So I clamped the sacrifical boards to the side at each end and used a long straight edge to ensure these "rails" would remain straight.  Below, I'm using my router, jig lubricated with car wax, and a 3/4" flat router bit.  I only took off about 1/4" per pass and had to make several passes.  A larger plung router would have been nice, but patience and a soar hand allowed me to get this task done.

Once the router was shaving off just a little bit over the entire surface I had a close enought to perfectly flat surface.  So I used my Random Orbit Sander with 120 grit sandpaper to clean up the  surface.  Flattening Workbench top, sanding
