Query: perfect for table saw inserts

I bought these in order to make a zero clearence insert for my table saw. The dimensions are 11"x15"x .25". The Phenolic is extremely strong even more than I had imagined it to be ),very flat, and seems like it will be very durable. I ended up making three inserts out of this one sheet made two dado inserts and one zero clearence ). The Phenolic was very easy to work with, I used a jigsaw to make a rough outline of the throat plate and then a trim router to have it fit precisely. I am very pleased with this product, I was hesitant at first to buy this product because of the bad reviews, but if you are looking for a strong, level, and durable insert for a throat plate then this is the perfect product. I wouldn't use this for router base plate too thin ), a table saw sled too expensive and too small ), but for inserts if you like building your own this is a must have.
