The wire won't break if you are using lock wire. Are you using the light wire they use on tamper seals?

Does anyone have a source/part number for those screws? I have buggered them up pretty good and want to replace them next time I remove them.

In aircraft (and all other applications I am familiar with) safety wire is used to prevent an important fastener from rotating, not to show you later (maybe after it is too late), that it has rotated.

Wire used to indicate wither something has been tampered with is not safety wire.

That's cheating!! Just think of all the `safety-wiring in impossible places', `bandaid application' and `vocabulary improvement' practice you're going to be missing out on.

I went just through this, the proper time to do it is after you have finished the ground run of the engine which is PAP Section G6 last step.
I asked a local A&P for the safety wiring as I was afraid the proper procedure would be to twist 2 wires from screw to screw but he told me to just thread the wire through all screw holes and do the twisting between beginning and end of the wire. No particular problem to thread the wire, use a plier with a bent nose and if needed unscrew a little the screws that have the hole in a position hard to access. You still can tighten the screw once it's wired.

I've also been told (dark humored cynic) that the real purpose of Seat Belts is to make it easier to find the bodies.

Jeff looks inside his 150 mph 62 Jaguar. Seat belts. What's a seat belt?

NOTE! You will have to drop the gascolator bowl after you do some fuel flow testing in the engine commissioning process. Thats to check for debris. So wait until after that to safety wire the gascolator or you will just have to cut the wire anyway. Hang some tape or something on it as a reminder.

As I built the plane I checked and initialed every step and signed each page when all steps were done. If for some reason I skipped a step on a page to do it later, I did not sign the page and I put a sticky note on it that stuck out visibly.
Anyone care to opine why page 28-05 (Revision 2), Step 2 says "Safety wire the four screws holding the gascolator bowl to the top of the gascolator." if you're just going to drop the bowl later anyway? Mistake in the instructions maybe? Also, is there safety wire include with the fuse kit? I don't recall seeing any. Thanks for your replies.

You will need to supply your own safety wire, and twisting pliers. The wire is available from vans webstore, and won't cost much. It's handy stuff to have in your miscellaneous bits and pieces collection. Also useful for unexpected blood sampling. Trust me, I know
