...Just a quick update to any other fellow newbs that may be reading this:
I bought the new Dewalt Porta Band, and the table from swagoffroad.com, and just for the record it is NOT a direct fit. i.e. the black part pictured here with two holes is the stock Dewalt plate, sitting on top of the Swag plate, the holes do not match up.
You have to take apart part of the Dewalt, take out the sliding part that is threaded for the two screws that hold the black plate on. Then you have to cut that piec in half, and reinsert it to make it match up with the Swag plates holes.
Not a big deal, except that does lead back to my initial concern of: ...How do you cut the metal part/s you need to make the saw work, if the saw is not set up to work properly without first cutting the part??
Well you could use a hacksaw (which I do not have), or maybe the cutting disc on a Dremel or something. But I ended up using the not fully assembled porta band to cut the small part in half. I got it to work, but I would not recomend it. I held onto the part with a pair of visegrips and some pliers, but there isn't really any way to run it through smoothly with the guid plate off, so the part ended up getting ripped out of my hand a few times before I just muscled it through.
Anyway, it seems to be set up alright now!
