–Went for 8-mile bike ride around San Andreas: Oceanview, Peaceful Valley. Exhausted.
–Finally got the Coffex tube to seal (o-rings) and it’s working with the new pump. Nice.
–Played around with Teknas, and though I can’t be sure, it appears that just sitting for a while caused a couple of the diaphragms to seal. Nice. Testing this with 5 leaky diaphragms in a dated bag; will check them periodically.
