Replaced the left fuel drain with a new one. It wouldn't always seal after draining fuel. Then replaced the O-Ring in the offending item and tucked it away in the fly-away kit as a spare.

I also re-weighed the plane after installing a bunch of goodies since the original W&B was done and moving from a Lithium to a lead-acid battery.

The current W&B is now:
Left: 404 Lbs
Nose: 239.5 Lbs
Right: 398 Lbs
TOTAL: 1042.2 Lbs and a BEWCG of 77.63

This represents a 60 Lb increase and 1.07" aft change from the original weigh-in, however, in that time, the following have been added:
  • Dynon autopilot servos x 2
  • Second 10" SkyView screen
  • Dynon Transponder
  • Dynon ARINC Module
  • KLN-90B GPS
  • All wheel & gear fairings
  • FullRiver HC20 lead-acid battery (14.5Lb increase right here!)
  • Second seat frame & automotive seat cushions on both
  • First aid kit on the rear bulkhead
  • Cowling, wheel fairings & tail fairing painted.

Step 1:
Verifying the scales are accurate - or at least, agree with each other. Two agreed, one was 50g off. Close enough...

Step 2:
A couple of ramps, and the hook from a winch the hangar's original builder thoughtfully provided, to pull his '185 in, tail first...

Step 3: Centering it up.

Step 4 weigh in time...twice, then average the weights. 400g difference in total BEW across the two weigh-ins. Close enough.

Step 5. Maths time.. I'll spare you the that. I cheated and used Excel!
