Todays Project - What did you do today?

[PixMan]

I don't do many "pay" jobs, but here's one I tackled today. It's a motorcycle "model specific" mount to fit a 2011-2014 Triumph Tiger 800's windscreen support bar. By clamping to the Ø12mm bar, it positions the 1" ball is such a way to afford fitting RAM® GPS (sat-nav) mounts. On my own bike it puts my Garmin Zumo 550 just above the clocks (instruments) and puts the GPS screen in the same focal plane as them.

I've sold only two, so this would be serial number 4. If I was actively marketing these I'd have a lot more sold, but I just can't get what they really cost in time. So for the few people who seek me out, $40.

The blank after "op1". One of these days I'll get around to making a ball turner attachment for my lathe. I roughed this out with a form tool, fit it to a radius gauge with a file and polished it. The measurements around the ball vary for .996" to 1.000", so it's "close enough" for the intended purpose.


Milled away a touch more than 1/2 the diameter, rotate the spindexer by 180º, drill & counterbore from the back for the M6x1x12 stainless steel socket head cap screws. I make a second piece long enough to be the mating clamp part, leaving just a little long after cutoff in the lathe to aloe facing the end to length while clamped together with .030" (0.8mm) shims between them. With the shims still in, I put the assembled part into the spindexer again to drill and bore the Ø12mm cross hole.


All done. I'll ask my customer if she wants the "Scotchbrite" buff or just shiny like this before shipping out on Monday.


It takes about 5 hours to make one this way,
