It is pretty easy. I do my own. Magnification helps, either a visor or a table magnifier or a dissection scope. A jig to hole the carriage that the crosshairs are attached to is useful - and can be made out of kindling if necessary. Nothing special to it.
Indeed. I was flummoxed by crosshair replacement for many years, having sent a couple out for professional help in that regard. Then two years ago I bit the bullet and bought some .0005" tungsten wire and dove into a Fecker and a Litschert. I won't say its easy-peasy but certainly do-able. Like Brent, all it took was a magnifier visor, a steady hand, and a jeweler's screw driver and it was done. I wouldn't begin to try it without magnification. I just set the crosshair carrier ring on the desk, with good light, and hunched over it and did it.
Could you elaborate on your jig, Brent?
