I have bought some SBR12 rails and bearing blocks in an attempt to make a fancy flatenning jig for my router.
I haven't been able to see 100% everything that other people have done on the YouTubes due to camera angles etc, but I went ahead and bought some to fit the table I currently have.
The idea is to have two rails attached atop another 2 rails perpendicularly as to act as an X and a Y axis to move the router across the workpiece easily.
The issue I have found now the rails have arrived is that the holes in the rails designed for fixing them to a tabletop etc don't align fully with the threaded holes in the tops of the bearing blocks...
Is this something that is normal, or was I just naive to the idea that they would fit perfectly? Also, is there something you can suggest I do to attach these securely?
