I think the splitter is a little wider than an inch at the very front, but that's just a SWAG. We've got a coupla posts "in the can" that'll show up in the next week or so, but then I think we're gonna get pretty comprehensive coverage on the nose and splitter. I'd run over and measure it, but the commute's a bit long for me (I live in Utah.) Actually, the commute isn't a real short one for Freud, either. He's put a lotta miles on his car gettin these photos.
As far as being amazed, join the club. I feel that way every time I see a new batch of photos. I think Sparky has a handle on it: folks are gonna study this for a long time to come, based on the comprehensive nature of the coverage. It's a "how-to" for building a liner. I realize there's more than one way to skin a cat, but this cat's definitely gettin skinned!
Thanks for your interest in the project. We'll do our best to get your questions answered in the upcoming posts.
