Rat lapping
Has anyone heard of a metalworking process called "rat lapping"? I am
researching an old firm and found a reference in Google Books which lists them as " PRODUCT — Precision Rat Lapping & Grinding". Is this actually a process, or is it just an OCR error when it should say "Part Lapping"? Best wishes, Chris |

Well, there are lap dogs, and lab rats, and lab dogs, are there lap rats? Cheers! Rich |

Regards, EH The most common industrial venue for flat laps in my experience is in optical shops, so if your reference has any relevance to lens or glass working, that would implicate the process.

Likely an artifact of the OCR and a ligature of 'f' and 'l'. I know that "fi" used to be commonly printed as a ligature (squished together, so the dot of the 'i' merges with the ball on the top of the loop of a lower-case 'f' in certain type faces.

Rat lapping
I had an encounter with one of those last week. The Kido came into the shop to do some speech homework with me for 15 minutes. I was eating peanuts and tossing the shells into some kind of round military can 14"w X 15" h that is beside and under the cantilever of a smooth sided work bench. After numerous tosses of shells I noticed a mouse in the far side of the can cringing every time the shells where thrown at it and staring at me. When I looked closer it's tail looked like it got smashed in two places it the past. The Kido said don't kill it, and since there where only peanut shells in the trash can we drove it down to the end of the road about 1/4 mile. I dumped out the can and it ran down the hill. 24 hours later I tossed something in the can and there was the same mouse staring back at me ! I was kinda wondering how it got into there in the first place and now this. Twin mice with a genetic mistake in their tails? Lost pets that travel great distances to get back home? Time loops inside the military can that was once on the USS Eldridge ? SW |

SW Friend had a sqirrel problem He trapped squirrels by the dozen, relocating them several miles away in a different semi-forested area. Got to thinking there's an awfull lot of squirrels, and some of them are looking a bit familliar, so he decided to spray paint a few tails. Within a few hours the little beggars were back - so he decided to relocate them across the river, some 7 miles away. Painted tails were back within a day or two. He figured he had 2 choices - baptize them or learn to live with them. They are still there. |
