Stebel Nautilus Air Horn for BMW

Worked all afternoon getting the air horn wired up. mounted the unit on the sidecar frame in the front. Pre wired the unit to the stock horn switch and ...nothing. disassembled the switch, cleaned the contacts and spent 45 minutes reassembling the thing. A tiny little circlip is easy to remove but a bugger to reset. Damned thing still didn't work. Time for a new switch assembly it appears. I went over to Radio shack and purchased a pair of push button switches for $4.00. Decided to jury rig in a switch until I acquire a new BMW switch.
Fabricated a switch mount out of old junk I had laying around. Somewhat of a "hokey" mount but it functions and will do for now.
Horn is LOUD. 139 Decibels according to the paperwork. Uses a relay system and was pretty easy to mount. My non working switch added a couple hours to the installation.

I didn't have a spare key for the R100S ignition so ordered a key blank from Hucky's BMW Parts. Then I couldn't find a lock / key place that would cut it for me. I've seen some lock smiths who weren't exactly rocket scientists so how hard could it be? I gathered up a couple different small files and made an impression of my good key in a piece of epoxy. Then just slowly / carefully started filing on the key as close as I could to the original....and low and behold I had a working spare key.
