It will work. HOWEVER /forums/images/graemlins/smile.gif
If you want to keep iron particals from staining the wood you're working on, you'll need to carefully clean the chopsaw when switching back to the wood blade. Also, the wood miter saws don't have the built in clamp to hold the workpeice, so you pretty much need welding gloves (or a high tolerance of pain) to make cuts this way.
These are the main reason's I'm looking getting a dedicate machine to do this. That, and it's a big pain to switch back and forth.
