I'm planning to start building a combination tablesaw and router table workcenter. (I bought the plans some time back from Wood magazine online.) Its the nicest workcenter I've seen and I'm looking forward to getting started.

This is what it looks like in their picture:

The plan calls for mostly MDF and what they call "MDO", medium density overlay board. Now, I know what MDF is, but I've never seen MDO. Am I the only one?

Also, I'm planning to replace all MDF with Birch plywood instead. I don't really trust MDF to hold up to fastening long-term. Plywood seems like it would be more durable in the long run. Plus, using birch ply, I can give my workcenter a very nice-looking finish. I say give the shop stuff first class treatment so I might be able to do a half-way decent finish on something that really matters later.
