    Crankshaft repair ideas ?!

    How about turn down the crank. Bore out the flywheel and bush it down to new crank diameter and recut the keyway. Cut a new key seat in the shaft opposite the existing one?

    YES I am an C0636 owner. I would be willing to participate in a group focused on the C0636. However Electronic Lead Screws, digital readouts and such aren't currently in my budget or on my agenda.

    Right Angle drive for a Bridgeport style mill.

    It sure would. Unfortunately I have no interest in doing work for other people, so it's very hard to justify the cost and space for just my own projects and something I would use infrequently.

    Right Angle drive for a Bridgeport style mill.

    60mm stock bored 2nd over to 61mm. The cylinders on the bike were bored and fitted by someone else. I just experimented on a scrap one. I have a complete spare set to play with. perhaps some more aggressive porting.

    Right Angle drive for a Bridgeport style mill.

    I had not thought of putting the boring head in the chuck. Interesting. When I started I had no intention of boring the cylinders, What I started out to do was modernize the combustion chamber. Kawasaki triple engines were designed in the 60's when there was 100+ octane fuel. They tend not to...

    Thanks Jeff. I appreciate it.

    Right Angle drive for a Bridgeport style mill.

    Here's a picture of what I was doing in the lathe. The slug in the 4 jaw is bored to just accept the sleeve were it protrudes from the bottom of the cylinder. The machined band on the outside is concentric so I can dial it in and I take a skim cut on the face each time I chuck it up so the...

    Right Angle drive for a Bridgeport style mill.

    I have yet to do one. I have done some experiments on a scrap 2 stroke cylinder using a fixture in my 4 jaw chuck and a big fat boring bar. best result is between .0005 and .001 taper? I'm not sure how much can be successfully honed out? I have about 7 different cylinders I'd like to do, and I'd...

    Right Angle drive for a Bridgeport style mill.

    YES. I would have to make some sort of fixture on the carriage to hold and align cylinders. Ideally it would be adjustable for different size cylinders? I just don't have a good mental picture of what that would look like. Any photo's or illustrations I've seen of that being done include lots of...

    Right Angle drive for a Bridgeport style mill.

    YEP. That's kinda the way I was thinking. Do you think it could be rigid enough? Cylinders are usually cast iron lined. I've done experiments on the lathe but its hard to keep out taper just using a boring bar. Setting up a cylinder on the cross slide for a line bore is super fiddley. Wish I...
