509 Leadpipe Question

I would love a Kanstul H8 Leadpipe but hat would be a viable Alternative?
How loose to some manufacturers go? If you size at .005 larger and .008 would lose a seal are they .006-.007 or is it that some manufacturers pipes leak? It wouldn’t surprise me, just wondering if there’s a consistency to how loose. I had a pipe direct from from Bach that I had my tech size and it was off that size in the opposite direction by like .005.brassmedic wrote: ↑Sat Jul 01, 2023 9:46 am I size the pipes I make at .005" less than the bore size. Otherwise they won't fit. Some makers size them even looser than that. I don't think .001" difference would affect anything. But a .008" gap would probably not be air tight and wouldn't play well.
What I mean is, for example, a .500 bore pipe is actually .495 or less outer diameter, so if you put that in a .508 bore tube, it's .013 or more difference between tube ID and leadpipe OD.Matt K wrote: ↑Sat Jul 01, 2023 1:15 pmHow loose to some manufacturers go?
