The Rottler machines: look like this:

I could not find a good picture of the Sunnen, but it is similar configuration. The block is held in place while the boring mechanism bores a hole in a precise position that is relative to crankshaft position and not loosely related to the cylinder deck

You can explain away all of these common machines if you wish. I have already said that I agree with you about your honing method used on a new liner.

With roughly 300 million people in the US, your math would come up with only 300 people nationwide that would recognize this equipment. That's a little pessimistic, especially since these machines have been constantly referred to in Hot Rod engine building magazines for the last 25 or 30 years. I expect that there are 300 in the hoaky little county that I live in that are aware of this equipment.

If you must go get boring work done at a machine shop, see that they use machines of this configuration. It should not be difficult since my look at the websites, such as Kwik Way, for the old fashioned equipment now only show equipment of the Rottler configuration.

This concludes my explanations and recommendations. You can lead a horse to water, but you can't make him drink.

Have a great day,
