Makita RT700 Router – Wood Flattening Jig

Hi,

I’ve been using bamboo cutting boards in my kitchen for a long time. After extended use, they always become noticeably worn (cutting marks, bumps, …). To avoid throwing them away, I planned to mill them flat myself to make them smooth again.

My inspiration came from these videos:

Since I already own a Makita RT700, I adapted the concept to the materials I had available.
All you need is an RT700, some M4 screws, and 2020 profiles.

Result:
The milling worked, but the result didn’t really meet my expectations.
There were very fine grooves on the milled surface (only noticeable by touch, not visible).

I’m not a woodworking expert, and unfortunately I don’t have a proper workshop; so I had to work on the kitchen floor. That, along with the lack of dust extraction, was probably the reason for the fine grooves in the cutting board after milling.

For now, I don’t have further need to work with it — I’m missing a good workshop.
I’ll just buy new cutting boards when I need one.

I’m uploading it here in case someone else can make use of it.
