Thank you Steve- good advice. He's done carbon barrels before, I see them more and more in his shop each time I pay him a visit, especially the last few times I've been in since summer. If for Some reason he is not able this time, I'll certainly ping the forum for availability- I have the barrel being shipped to me this week, so I have no choice! I trust him with all my projects though so I'm confident he will be able to do it.
