Hmm okay i figured with a belt sander would work pretty quick, i literally was hoping to take off like 1/64th of an inch all the way around off all of them and then i figured they'd drop right in. The other reason for doing it that way is the tiles dont sit totally flush against each other so i was kinda hoping to knock any high spots off them.
If you guys are saying it wont work you probably know better then i would. I could take 1/16th off 12 of them and they should all drop in minty. Nobbie lets see if anyone closer has a wet saw that could help me out, but if not, driving to the west end isnt really a big deal considering i'm at least 180 bucks into this project already anyway lol (that includes materials, welding supplies, and a case of beer for my welder).
Oh yeah i have 4 extra tiles, and can get more easily, they're only like $1.75 each. Tile's will always be removable so i'm not sure what the question there was.
