Nice job, good write up, great pics.
The gob of grease on the cutting tool to catch many of the chips is smart. If a similar job was done in steel, the cutting tool can be magnetized to hold the chips. (Wrap several turns of a stout wire around the tool and momentarily DC power through the wire--touch each end to a battery post. For smaller tools can be magnetized by stroking lengthwise with a strong magnet. Try reversing the polarity of the current or stroking the other direction to remove the magnetism at the end of the job.) If the tap is removed part way through the cut then reinserted, I like to put it back in by hand with good feel for correctly threading. Then put on the tap handle and keep everything straight.
Swarf. That's a new one on me. I've always called them chips, as does my Boeing retired master machinist friend. Anyway, get them all cleaned out. Some might want to pour oil through the engine to flush out more of the chips..errr, swarf.... Pouring warm 5W-30 oil through (thin oil washes out more), then fill with oil (old oil and filter will do), run a very short time, stop, drain, put on new filter & oil, ride, enjoy.
