I haven’t posted in about a week, but I’ve been pretty busy acquiring a bunch of stuff that I’ll need in the coming weeks. I decided it was high time that I think about wiring – so I did, coming up with a few diagrams, wire lists, and connector needs, and put a bunch of stuff on order. I’ve been keeping the UPS, USPS, and FedEx delivery drivers busy this past week!
A short list of things that I’ve acquired in the past 7 days:
- Lights for wing tips, rudder, and belly
- Wiring for most of the fuselage, minus the instrument panel
- Electrical connectors for wing-to-fuselage junction
- Electrical connectors for lights
- Transponder antenna
- Flush rivets for fuselage
- A bunch of different sizes of AN bolts
The first few in particular required some planning that I have in diagram and spreadsheet form, I’ll post them here to help others.
Below is the spreadsheet with the wirelist I have (so far). The lengths of the cables came from the colored lines in the diagram above (Visio has a measure tool), to which I added 10%, and then after summing it together, I rounded up a few feet to something that made sense. In the case of the M22759/16-22 wire, I just decided to order a 250 ft spool, since there was a healthy price break, and I figure I’ll be using a lot of it when it comes time to wire up the instrument panel (IP). I ordered all the wire from Prowire, since there prices were quite a bit better than Aircraft Spruce. Prowire sells both M22759/16 and M22759/32 wire, the difference is in the thickness of the Tefzel jacket. Although the lighter weight of the /32 variant is tempting, I would caution others to buy the /16 variant of wire for one reason: the Tefzel jacket on the /32 wire is thinner than the /16 version, and I found that the environmental seals on the electrical connectors I got for the wing wouldn’t work with the thinner wire. The difference in weight is negligible for a small GA plane.
Thanks for sharing your ideas & build progress Jetshine. I look forward to getting started on my tsi next spring. Would you share the product detail of the bearings you used to build the “short” torque tube carrier? Excellent thinking by the way,
