Inspired!
Well done Sandro..
I like what you've done. Luckily the ribs on the LED unit will stop any rotation in the rim too, and the silicone will finish the job off nicely. That said you shouldn't need the silicone to seal the headlamp as water will have gotten into the shell with the original arrangement anyway. It just drains out of holes in the shell. It will stop any movement of the adapter against the rim though, which will be a good thing.
I definitely need to get an adapter and retaining system prototyped for these lamps.
My appeal for the loan of a rim still stands... Please anyone.
Rob beat me to it with the Anglo-US translation-conversion of units, another reminder of two nations divided by a common language!
It's even more confusing than at first sight, as in the US they say "six thirty two" and "eight thirty two" whereas we would be more likely to say "six thirty seconds" or rather "Three sixteenths" and "Quarter" for the later. The only thing worse is the metrification of inches! (0.25 for 1/4")
I did my apprenticeship in imperial, but I'm glad the UK has embraced the Metric system now and works only in mm and Meters (except for cm which dressmakers seem to prefer!). My Norton hails back to the imperialistic days and can't even keep to one system, with thread rates in particular being all over the place!! I wonder what thread rates are common in the US ? Please tell me it isn't Whitworth!!
S2R looking good Sandro... Enjoy..
