Re: Why don't barrel vendors provide bore measurements?

When I had access to an appropriately sized 3-point bore micrometers at work I took some measurements of an Accubore B66, Drake Ceramic (66mm) and the OEM barrel of my old Yamaha CS-V (65mm). The differences between them are substantial. The Accubore was very nearly, but not quite cylindrical, while the Drake had a lot more convergence. The Yamaha was somewhere in the middle.

The Drake's pilot bores for the mouthpiece and upper joint were noticeably tighter than the others and might be a contributing factor of reports of their exteriors cracking after some use.

One thing I found odd was that the outlet of the Yamaha barrel was smaller than the inlet diameter of the upper joint whereas the Accubore was nearly perfectly matched. I take it that bore-matching isn't all that critical?
