I am teaching myself to weld- small mig no-gas, yet. I built a very sturdy platform for mounting a GPS (or anything really). See links below.
Fits a 2005 DL-1000 with a Madstad windshield bracket, but I will soon check to see if it fits my wife's 06 wee. I made a couple more (for learning experience) - they aren't beautiful but I just put 800 miles on my first one (after prototype) with a Garmin 2610 and no problem. No vibration - I was satisfied.
It's made with 1/8" X 1" steel flat bar. If I can find some 2 or 3" flat stock I may make the over dashboard piece out of that instead.I would not drill the holes in the over-dash piece so you can custom fit it to your mounting bracket.
