    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...

    YES. The SHARP Lathe with DRO and Multifix Tool post is a pretty serious piece. I'm guessing 7 to 8K for it alone.

    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...

    Right Angle drive for a Bridgeport style mill.

    That's the one I'm looking at. To do motorcycle ore snowmobile cylinders I would probably need about 8 to 10 inches of travel. Rigidity is the big question. Especially without the outer end support.

    Right Angle drive for a Bridgeport style mill.

    Getting a consistent and smooth feed while cranking up the knee would be a challenge. Might do for a one of.

    Right Angle drive for a Bridgeport style mill.

    Not enough travel. My BP clone has only 5 inches of travel in the down feed function. I've done it but it has to be a very short cylinder.
