[QUOTE="Magnetoman, post: 63551, member: 2806"] With that DigiCam you would have to machine your own adapters to lock it to the Vincent crank or cam, plus fix the housing to the engine. Given this, for only ~$50 you can buy a rotary shaft encoder with its own digital display and spend the same amount of time machining adapters. Since with modern fuels we're just guessing on the timing to within a degree or two anyway so 0.1-deg. resolution is of marginal practical value for that. However, it is useful for checking the cams. If you were doing this regularly it would be worth it to have digital interfaces to write all the data directly to a computer file. But for those of us who aren't making a regular business of it, it isn't all that inconvenient to write down a crank rotation angle along with the lift(s) of dial indicators in contact with cam(s) lobes, then move to another angle and write down the new values, etc. [/QUOTE]
