thanks! but I feel like I am just stumbling through this, and learning a lot along the way. most of this type of stuff I haven't done before, but I'm taking it slow, making mistakes, and then trying again.
case in point: after mocking up the tach on the left, then the right...I have decided to put it right in the middle! I made a bracket that fits right where the ignition key originally mounted. I found a piece of metal at Ace hardware for less than $1. I measured the holes on tach and key mount, made a template, cut the piece using a basic scroll saw, bent one part of it to clear the tach cable, filed down the sharp edges, and drilled the mounting holes.
as you can see, I bolted the ignition switch to the right of the tach onto the top-triple mount that used to hold the original speedo/tach bracket. it looks a bit clunky there, so I may move it. Also, I think I am going to scrap the original idea I had with that switch panel, and do something a bit different...along the same lines, but maybe separate the oil/neutral light and the switches. I found the panel I made too hard to mount nicely to the top-triple. I shouldn't have soldered the wiring until after I had it mounted. oh well..live and learn.
