The main reason I got the bling-o-meter is as a rudimentary yard stick for reviewing video of speed in a certain part of the track (or at least, RPM). More lights = more fast. Easy.
The problem is that it’s nearly invisible in the video, because the steering wheel is between the tach and the camera. So how to fix it?
I noticed in the video that if it were directly behind the steering wheel on the column, it would show up perfectly, so I fabbed up a quick mount to get an idea of where it should go.
I briefly considered welding to the column housing, but after consulting with a friend who generally knows much better than I (Thanks Dave!) decided that there’s too many important unknowns that could be cooked inside the column housing (plastic bushings, grease seals, etc) to risk welding directly to it. He floated the perfect solution (as usual). Inexpensive and effective: a 2-piece shaft collar.
A little time on the wire wheel cleaned off the oxide coating on the un-threaded half, a little welding, and a coat of paint, and it should work great:
A little time spent on the little things that would bother me if they were staring me in the face before each run:
And now I should be able to get some use out of it. A little before & after:
