I called the local Pacific Energy store where I bought the firebrick, they didn't have any ideas, so I called Pacific Energy tech support. Paul,  the gentleman I spoke with said that the standard size fire brick can vary by up to a quarter inch depending on manufacturer. I bought USSC Model FBP6. I've been reading the threads about cutting fire brick, gosh! I probably only need an eighth of an inch. Any ideas? Thanks.
