Jerry,
My thoughts exactly. When I engrave I am usually at is for several hours in a row. I stand to do most bench work but I would not like to stand that long to do engraving...and I do like using the scope rather than just loupes. I did purchase some Zeiss binocular surgical loupes that give me much higher magnification and still allow me about 10 inches of working room between the loops and the workpiece. For the occasions when I can't use the scope, I used the surgical loupes. No, I need a good bench where I can sit and work and I'm trying to sort out just how high the top of the graving block should be above the floor. And I do have a good GRS turn table that the block sits on so rotating the work is not an issue unless I'm working on a 42 inch barrel....and then I have to do things differently anyway, as you point out.
