Thanks.That’s where the helpful advice came in handy! I ended up going with the router sled! Another person recommended I use a 2 inch bottom cleaning bit and it worked very nicely. amazon
I used one of these before buying a planer for flattening cutting boards.

It’s a 1/2” shank 2” cutting diameter bottom cleaning bit, I’m not sure if Amazon links are allowed but it’s like this one: https://www.amazon.com/dp/B07H8FDBTC/ref=cm_sw_r_cp_api_glt_fabc_0RB4DH97J9T8W4YA1MK2
