Trimmed yesterdays tapes and added a couple more, with flox as fillets in places.
Level ball is still floating in the petrol jar, no sign of dissolution yet.
Roughed up the sump sight gauge 1/4" up from each end, and for 1/4" around the inlet tube holes, both inside and out. Pinned a level ball through the inlet pipe to see if this would hold it in place whilst the second cap cures as a test, then filled the end with EZpoxy flox in the mold-released dremel cap to a depth of about 1/4"
