Machining new parts, however created, is a more difficult process than it might appear. These valves were originally made using male/female pairs of tapered reamers to get the necessary accuracy. They could be custom ground, of course, but you'd need a pair for each size of valve. It gets expensive in a hurry. 3-D printing is not able to produce the accuracy or finish required here without standard machining. Putting in a new valve is a "least-bad" way of dealing with this until something better comes along.<br />R. W.

I suspect that doesn't solve the problem if it's the body of the valve that is no longer perfectly conical, but you'd have to know more about 3-D printing and machining that I do to give an answer. In any case, I bet the economics are against it. And if we can just put a new handle on an off-the-shelf valve, that sounds like the way to go.Randall Hickshttps://www.blogger.com/profile/16246581917018679919noreply@blogger.comtag:blogger.com,1999:blog-1810478746663531557.post-20956362177668185332016-10-24T21:05:52.653-05:002016-10-24T21:05:52.653-05:00Could that some guy be a long time member from the...Could that some guy be a long time member from the Dayton area? <br />I missed the story on the missed opportunity about the Olympus, I had heard that car existed some years ago.

We might also point out that the old-style valves are open when the handle is perpendicular to the pipe, and closed when it's parallel, whereas the modern valves use the opposite system, which is the usual and more obvious arrangement. But it's very confusing for the operator, and potentially disastrous, if the arrangements are mixed, so the handles had to be modified. The new replacement handles will be much appreciated.<br /><br />I just noticed a milestone: we have now gone over 2,000 posts, for what it's worth.<br /><br />And a word of thanks to "some guy from Ohio" for driving out all the way to help with the Michigan car. He might be setting a record of some sort.Randall Hickshttps://www.blogger.com/profile/16246581917018679919noreply@blogger.com
