My Uncle used to rebuild his Harley every winter. Rode in the patio door. Rode out in spring. He set up a table right behind the couch so he could watch TV with the family, and build the motor.
That memory firmly planted, every air cooled VW engine I rebuilt was assembled "in house", two in living rooms. One 1906cc stroker, we brought a trans into the living room to start and run it, for a 20 min initial break-in. Used the coffee table. Small old house 30'x30', open windows, winter, rain & wind, loud music from a compilation album (vinyl) by a new band called Mettallica .(not a misprint here, look it up)
Within the next few days I was cleaning the "garage"(5'x30'?? for convertibles only!), for installation in the buggy, and pulled my Great Grandpas Marx CV right out of the dirt floor with a soil rake. A buried Jackpot. It was my Grandmas childhood set. She put it there after setting up a tree, the train, and then finding out her new husbands mother had been killed by a reckless Detroit trolley driver. The driver ignored a hundred+ yards of warnings that she was stuck (fired, but no charges). Gramps was there with her, and got to talk to her, and say goodbye, as she lived for while. But I guess he didn't like any railed vehicles after that. He wouldn't play with my trains with me. It hurt my feelings that he wouldn't, but I always figured he was just avoiding stepping on my other Grandpas toes(a Lionel collector). I didn't know anything of the trolley biz until I found the MARX CV train, and asked Grandma if she knew anything about it. She asked I take it, but kept it hidden from him. He suffered in silence while I played with mine so many times. It needed a repaint, etc. And got a baked enamel finish in Great Grandpas old electric stove that was hooked up in the garage(summer cooking pre-air cond.?) Don't try that in the house! Even on low, it really wreaks, but it worked nice!
I would have likely rinsed the opened computer for a bit with hot distilled water, then put it in a box of rice for a few days(phones too). Used to put soda-pop covered arcade video game boards, and power supplies into industrial dishwashers (no detergents, etc.). Result was clean, shiny, working boards. Longest dry time ever? about 5 days, 2 after I took the relay covers off. They filled with water...so next time I only rinsed it! Hey, water is known to dry.
I ruined my Mom's brand new hardwood floor, stain and all. I pulled a Christmas tree fleece out from under my track because I feared any sparks setting it ablaze (& repositioning presents for making tunnels easy). A few hours each day, of all die cast post war running(cars too!, so lil' bro couldn't Casey Jones it with the 1033.) on 0-27, with the straight edge ties. It ate up a big rounded square around the tree. Curves were the worst areas.
Nobody even noticed till the tree came down, and the track came up. Semi-soft still I would guess. The old floor, and the repaired floor took the beatings fine.
