Job #1 was to attach saddle to the bar and it had to be perfectly square. Problem was that Vixen bar has 12° angle so regular toolmakers square wasn't good for this job. I used large V-block that has 2 faces perfectly square and to make sure that the bar is in full contact with V-block I used old toolmaker's trick by placing 2 thin shim strips between V-block and bar. If one can be pulled it is not square.
