I was always told that a tool bit boring a cylinder would fracture the metal immediately under the surface being cut.....how much would depend on the tool metal being used, the metal being cut, how sharp the bit was and how much of a cut was being taken. So, the honing would remove the "loose" metal and as an added bonus, would put a cross-hatch on the wall giving it an interrupted surface for good oil control.
I've never owned or run a Lister, but I remember hearing them as a kid generating power for out-of-the-way cabins in snow country. I always liked the sound of that single cylinder just huffing along making beautiful music. Hell, they still sound beautiful !
I think when our youngest grand daughter leaves the nest, that my wife and I will be leaving the steaming heat of Florida and relocating to Idaho/Montana or some place similar. By then, I will be dangerous because I will have read all of your posts (and remembered at best, only half of what has been discussed !!!! ) and will start seriously shopping around for a 6/1. In the meantime, you guys will keep my dream alive for which I thank each and every one of you.
I would still be interested to know the valve stem sizes of the In/Ex valves of a 6/1. If any one knows, I would appreciate a heads up. ( I owned a Sioux 645L valve grinder for years and buying a 6/1 sometime in the future would be just the push I need to acquire a used machine to play with.....yes, I'm still a kid.)
I appreciate your insights, your humor and your pictures. Because I don't really have any experience with these engines, I will spend most of my time just reading and Looking at what you guys have to say. Thank you in advance.
Have a nice day. wormshoe
