Joe ... Ditto to Sprucey's comments.Hey Joe, don't be too hard on some folks around here. We're still a little gun shy from a former member who used to berate everyone for their own benefit. I'm certain that it was just a misunderstanding earlier, no ill will was intended. Once you get to know the group you'll find most of us are quite jovial in our interactions and can even offer some sage advice to boot.
Could you just lay the bottom plate right over the tile and not bother with worrying about cutting?
