Thanks for all the comments and critiques.
Phaedrus, I thought about the plexi-glass but ultimately decided against it. I think that over time it is going to get scratched/dirty and obscure my view of the cut. I do see how it would add to the safety though. I couldn't extend the sled runners for the miter slot any further since they would hit the end of the slots in my outfeed table before the blade cleared the front rail. This thing is big!
ArmedFerret, I was really happy with the Watco Danish Oil. I will definitely be trying it again on other projects. My only gripe with it is how long it takes to dry. Three days, really? Mostly that's due to the cold and damp climate here in Western Washington, but I hate the heat, so three days is a price i'll gladly pay to live here.
My concern now is where to store this behemoth when not in use. I also need to build a miter sled and an artillery fence system.
