Cubic inch question

"Just don't ask me to offset grind your merc crank to 4 1/8"

If you can do that with a router and string I'd like to see it.

C'mon Mart.... That takes two strings and an angle grinder. Can someone show me the cubic inch displacement of my stationary engine? One cylinder, 6" bore, 12" stroke.
 
Yeah. I'll walk you through it.

bore * bore * pi /4 *stroke*no of cylinders

6*6 = 36
36* 3.1416 = 113.0976

113.0976/4 = 28.2744

28.2744 *12 =

339.2928 * 1 = 339.2928

So your single cylinder motor is 339.3 cu in.

Thank you very much Mart! The brass tag on it states that it produces 8 hp at 300 rpm. I run it at 75 rpm.
 
You could’ve been getting a load of laundry done while you were there.......I think watching and listening to one of those motors is to me, the most relaxing thing.....kinda like watching cows graze and chickens peck the dirt.....that’s quite a collection you have Gary!!!!.....Mark
 
The big stover is mine and I have a 3hp as well as some old air cooled stuff. I sold the gas powered maytag washer. About 5 of us set up in that area every year for the last 34 years at Lynden Wa, in August. I feel smarter now that I understand that formula. Thanks
