Cleaned up the garage then cleaned, painted, and assembled the suspension uprights. Could have had them powdercoated but didn’t want them the same color as the suspension arms, didn’t want to pay a fee for another color, and didn’t want to disassemble them to remove the bearings. Just cleaned them up and spray-painted them black which will be good enough for now.

Noticed that the front brake pads – due to tolerances in their positioning – can end up about 0.050″ above the brake rotor. This isn’t optimum since the top edge of the brake pads aren’t doing anything and will likely wear with an overhanging lip on them. The brake caliper adaptors will be machined down about 0.060″ to ensure the full face of the pads are working.

In home news, discovered a puddle in the kitchen and it was wet on the shelf below the sink – uh oh. Removed all the bottles under the sink and wiped a finger over all the hoses and pipes – nothing. Cleaned up the leak, dried out the shelf, and put everything back, only to have it happen again later in the day. Okay, take everything out again, search everywhere, and again, nothing, grrr. Sitting there trying to assign blame, one of the cleaner bottles that had been removed from the shelf was a squeeze-pump type. I remembered something similar happening with our hummingbird feeder – and the gas tank in Kimini. That is, when you have a container that contains both air and liquid, the liquid pickup is at the bottom, and the room temperature fluctuates, the air inside the container expands when it gets warm, pushing the fluid out. Then at night when it’s cool, the air inside cools and contracts, pulling air back into the bottle. Next day the cycle repeats, and given the very warm temperatures we’ve been having, it became suspect. Sure enough, loosened the cap on that bottle and presto, the “leak” vanished. Just a lesson in how sneaky thermodynamics can be in seemingly unrelated situations.
