You haven't wired the banjo bolt!!!! OH, THE HUMANITY! Seriously, looks good to me but I'm just an IT guy that likes track - I'm sure you aviation types see it quite differently. We just need to have zedpilot chime in to complete the thread. Sean, you'll have to see how badly mine fails the next time you see it

this is from the WERA website on saftey wiring as found at http://www.wera.com/rulebook/default.asp#ch8: 2. All racebikes must meet WERA requirements. A racebike will not pass Technical Inspection and will not be marked with a Tech Sticker until the racebike is in complete compliance and the rider has completed and submitted his Contingency Tech Verification Form. If any of the items to be inspected are hidden from view by bodywork, those sections of bodywork must be removed prior to arrival at technical inspection. a) The following item must be safety wired, or secured in a manner approved by Tech: •axles or axle nuts •oil filler caps •kickstarter retaining bolts •axle caps and/or pinch bolts •oil drain plug(s) •removable exhaust baffles •brake caliper bolts •*oil gallery plugs •radiator caps •brake torque arms •oil lines •coolant drains •speedo and tach cables •spin on oil filters/filter bolts •any pressure fed lubricant line •*fork oil drain screws/bolts •rear exhaust mount(s) (all) I don't see brake banjo bolts mentioned.

Individual interpretions of the FAA's guide book can be derived from http://www.airweb.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf/0/99c827db9baac81b86256b4500596c4e/$FILE/Chapter%2007.pdf Page 19 starts the description of safety wiring. It is worth looking at as there are diagrams showing how it should look. My example would probably fail for not maintaining a light tension. BUt as long as the bolts are pulling tight against each other, don't cut or poke my skin and I am not leaving the ground for extended periods of time I think I will be OK. I was taught to drag a cloth across the end of the wiring job and if it does not snag it was good. Here is an excerpt from the chapter: 7-124. SAFETY-WIRING PROCEDURES. There are many combinations of safety wiring with certain basic rules common to all applications. These rules are as follows. a. When bolts, screws, or other parts are closely grouped, it is more convenient to safety wire them in series. The number of bolts, nuts, screws, etc., that may be wired together depends on the application. b. Drilled boltheads and screws need not be safety wired if installed with self-locking nuts. c. To prevent failure due to rubbing or vibration, safety wire must be tight after installation. d. Safety wire must be installed in a manner that will prevent the tendency of the part to loosen. e. Safety wire must never be overstressed. Safety wire will break under vibrations if twisted too tightly. Safety wire must be pulled taut when being twisted, and maintain a light tension when secured. (See figure 7-3a.) f. Safety-wire ends must be bent under and inward toward the part to avoid sharp or projecting ends, which might present a safety hazard. g. Safety wire inside a duct or tube must not cross over or obstruct a flow passage when an alternate routing can be used. |

I definitly agree "safety wiring is an artform" unfortunitly nobody has ever accused me of being an artist. Our mechanics at work just shake their heads and walk away when they look at my wiring skills. It's been almost thirty years since I got out of school for it and I don't practice much since they would shoot me if I actually tried touch our plane. I wired most of what is on WERA's list, started with all the fluids, drains, fillers etc. Now whenever I take something off, if it is on the list I drill it before putting it back on. PITA!! Going to have to invest in drill press, trying to drill these by hand and not snapping drill bits is next to impossible. |
