Jerry, you're making what, with the Infinity gauge is a simple procedure sound incredibly complex, enough to put newcomers off ever attempting lock mitre joints which you have previously made on the chest that you made. It is a wonderful joint, a bit tricky at first with several test cuts needed but with that gauge it becomes a simple easy set-up.
The gauge is very simple to use for a normally sighted person, but if you do a lot of your woodworking by brale, sometimes you need a work around, hard for a normal person to grasp.
What I have described, to me anyway, seems to make the set up even simplier, just the way I see it.
Confession, I have recently found that my magnifying visor does allow me to see the gause much better. But as you know Harry I tend to make simple things more complex, I really don't want to cause anybody heart burn by my thinking and doing what you have pointed out.
Not having to even look at the hash mark any longer is easier for me, seems like it's a step in the right direction to me, but that's just me.
My dear friend Harry, as usual, if I don't do something your way, you criticize it due to your fast knowledge and experience that you are so well known for and admired. You also know that I am an experimenter and not always interested in doing things like everybody else does it.
It's easier for me to see the cursor on Incra's primary scale that to see the hash mark on the gauge, and by only having to see it one time for the height adjustment is easier for me than having to find the center of a workpiece and then try to line hash mark up on that center line. It's just so easy to crank the bit up to the proper height for any given thickness of material, just seems easier to me.
I do really like the miter lock joint and hope that those that are not familiar with it will eventually look into it.
