Hello gang,
I recently purchased 2 phenolic zero clearance inserts, and for some reason, they are slightly bowed, so they do not fit flat at each end. Can anyone tell me if or how I can flatten it? I did get it as flat and level with the set screws, and clamped a plank on top, and slowly raised my dodo blades until I was through 1/2 inch.
What other material is suited for this task?

you can plane it, but it’s going to be hard on your knives… also, if it’s painted on top – you might end up having a non-uniform colored insert (visual wise).

I used to make my ZCI from MDF, and finished it with poly – it was very sturdy, smooth, and darn cheap!

for my current saw I had some leftover phenolic material that I used for the ZCI though – it’s super smooth and very hard, I really like it. it machines just like wood.

I just use hardwood scraps. You can machine them just like anything else and they are cheap.
