No problems with the fit Mike. If we were perfect we'd probably pay someone else to build it! My boat has more of these than I care to think about. Like Bill says, and I'm paraphrasing, Miracles only occur after screwing up. In this case screwing up means, being human.

Looking great so far.

Hey and Josh, 1000 hours to build a Zip is just fine. You put a lot of detail into her. I'm pushing 1800 hours on my build so far.

Wedges and shims like that just show your commitment to making it right now and avoiding problems later.

That's the way I like to look at it. :)

Well, the shim is epoxied on. After sanding away the epoxy mess, the knee looks a little rough. But, at least it fits much better now.

I Haven’t set a transom yet that didn’t have a shim under it. It’s like hanging a door frame, they give those shims at the lumber yard for a reason.

Keel attached.

Drawing a little inspiration from GDCarpenter, I didn't use any screws to attach the keel to the frames. I only used thickened epoxy, and bronze carriage bolts at the front of the keel.

It's still a long, long way from the water... but it's getting there.

Reached a small milestone this weekend. I laminated on the last remaining piece of the keel, and epoxied & bolted the transom knee permanently.

I also trimmed the aft overhang of the keel. That reminds me! If you buy the Dremel brand "universal" multi-tool saw blades from Ace Hardware... they do NOT fit the Porter Cable multi-tool. Just FYI.

Although my execution of it wasn't perfect, I'm happy with my decision to build a laminated keel. The forward bend was very easy, with no resultant "bulge" in the aft area where it's supposed to remain flat. The full thickness along the back half of the keel, combined with the fact that I clamped a 4-foot level to it, helped to keep the aft section flat.

Once all that was set & the epoxy cured, adding the final laminated piece to the forward end was very easy.

Thank you, Neel!

Here are a few more progress photos. I've got notches cut for the floor battens (two of them, anyway). I'll be ready to epoxy the battens into place soon. My plan is to clamp 4' levels to them in an effort to keep them flat / minimize warp. I've also done a little preliminary fairing on the transom & cleaned up the keel-to-stem joint a little more.

I finally got around to buying more mahogany to finish the floor battens. My son helped me rip the boards yesterday, and I'm hoping to make a little more progress this weekend.

The problem is, the lumberyard only had 8-foot boards. So, the floor battens will have to be joined in order to be long enough. My question is, whether to use a scarf-joint or a half-lap. Now that I have a router, the half-lap seems like it would be easier, as I wouldn't have to make a jig for a shallow-angle cut with a saw.

However, I don't know if one type of joint or the other would be any better / stronger for this application. Any suggestions? (Any reason not to half-lap?)

Mike, the scarf probably has the edge in strength. There are pitfalls with making a half lap too if you don't cut the the exact center. But on a scarf if it's not perfectly lined up you can get a hump or dip. You can always laminate on the inside after the flip if you have concerns about strength. Since it's a zip and not a big inboard trying to go 60mph I bet either would be fine.

Matt,

Thank you. That's kind of what I was thinking.... that for a boat like the Zip, a scarf joint might be marginally stronger than a half-lap for a floor batten, but that either would work fine.

I watched a YouTube video on making a scarf jig for a table saw https://www.youtube.com/watch?v=pCurDJPH2SE, and it looks pretty easy. (The guy was making angled headstocks for guitar necks.) However, it's one thing to support a guitar neck when sliding it across a table saw at an angle — and quite another to support an 8 foot mahogany board.

I think for the tools I have available, it'll be easier to just clamp the boards to my work bench where they're well-supported, and just cut the half-lap with my router. We'll see how it goes...
