In my Belvedere, I have the tach on the column down low. It's pretty much useless, there's no real room to get it above the column (column shift car), and I want a dash mount. However, I do t want to drill holes in my dash.
So here's my experiment. I bought some neodymium-iron-boron magnets and a junk tach off eBay. These magnets are super strong. I gorilla glued six 10mm disc magnets to the bottom of the dash mount. The magnets are 2mm think so it doesn't raise it up too much.
Here's a pic of the assembly stuck to the anvil on my vise
It's a start. I'm not totally satisfied with it yet. I think it will handle normal vehicle accel/decel loads, but I think that road jarring might mess with it.
The tach mount base is 1x3 so I'm going to buy a couple 1x1x1/16 block magnets to get broader coverage and more holding force.
I figure this on my dash isolated by a piece of flannel cloth should be a viable mounting arrangement.
