I think im just going to cut them, thats the only practical way to make them fit on both the table and the board, I will keep them though for future repairs.

This is becoming a pain, and Im slowly realizing Im not prepared at all for the build, instead of a ruler I am using a tape measure, and its really hard to measure a flat surface against a curved one, and I'm unable to find a single flat ruler in my houser. I also ended up using some of my insulation board to build myself a few small shelves just because I needed a place to put things while I searched for the wood Im still not sure if I have, are there any places I can print out a sizing chart that has like 1/2, 3/4's and sizes like that on it so I can measure the wood against it??
