Yep John, sometimes just that little bit takes most of the effort

Twin, sorry watsyaname?
Not my idea, I just adapted it from a commercial product I saw on tweb....I like to think I improved on it, well it worked anyways.
Stew,
No crack, in fact when it first moved I wasn't sure what was happening. Was the key moving or was the tooling bolts destroying themselves. At first I thought the latter, then realised the key was moving.
Gave me that nice warm feeling we get sometimes

Even so, it was still tough going, even when the key was fully out I had a job to get it off the crankshaft keyway as it was pretty stuck even in there.
Here's a picture of the underside of the key, as you can see it had rusted in two spots, but nothing you'd call heavy rusting.
The rest of the key is in remarkably good condition and judging by the paint it's original.

Here's the top of the key, note the oil groove. This one was showing, just. But on the other side, the other flywheel, the key is in much deeper....umm, wonder what joys await us there......
