Yes, Harry, accuracy is king. The 45 degree mirror angle has to be spot on.
The line mirror axis has to be exactly 90 degree from frame mirror axis.
Unless both of these are correct then scanning lines will not be straight.
This first rig may not be up to that but it will work, albeit with some image distortion.
That in itself might lead me to play around with large deliberate distortion ........

Hi Albert hats off to you i know it does not take much when trying to make a mirror swing in a correct arc for it to be a touch off due to mounting lining up it can be very frustrating !
Klaas mentioned once its easier to repurpose things than make them from scratch for me i find that works as i am not good at the first and don't have the tools and skills .
So on this ....i like mirrors if i can be already lined up and mounted ...thus i always pick up those dead laser printers on the side of road when i need a polygon mirror but they are going cheap these days down to a square mirror ! .,,,,,,that works for the line mirror for me the hard one ...the frame i tend to make and after lots of trying i found the mirror surface you placed it on needs to be simple and accurate i pick a square ...lego block or what ever that is accurate and never glue behind the mirror even with a thin film of glue its enough to throw that mirrors reflection off .
Good idea keep improving where you can some times you only see it needs it when you have made something ,but yes see how you go with this and the results it gives,
