I need to cut a 7/8" deep rabbet joint
I am new to woodworking and have recently purchased a Bosch router as one of my first investments. I am building an 18" home theater subwoofer and bought a well known (in home theatre) box kit that I glued up, sealed, sanded, and painted the other night and now I am ready to mount the driver.
I have now decided that I want to flush mount the subwoofer, and the current cutout is a 16.75" diameter hole. In order to flush mount the driver, I need an 18.5" cutout. So I need a bearing guided rabbeting bit that will cut a 7/8" deep rabbet but I can't find any. Any ideas? The max I can find is 3/4".
Thanks for the help.
