Here's a closer look at that high spot on the middle batten...

I don't think it will be a big deal. I found it easier to deal with spots like that using a block plane, seemed to be able to sneak up to the right spot.

I like the idea of laminating the longer pieces in place.

Checking with my test piece of plywood, the fitting is pretty decent now from the transom forward to Frame #4.

That's odd, (but also a relief), because the floor battens are anything but flat. I bought a 6-1/2 foot level so that I could check as much batten length as possible. The high and low spots are within 1/16". I'm not sure how far I should push my luck with this. For now, I'm sanding less aggressively and using the long block to try to flatten everything out a little better.

Michael,

I have to squint too much too read 1/16th on the measuring tape. Carry on!

Merry Christmas, pal!

Looks good Michael.
Sighting down the length of your chine, sheer and longitudinals will pick up longer flats and curving lines that the level and batten will not. Amazing what your eyes alone will be able to detect. I always use that as my final test to see if the hull is truly fair and ready for sheathing.

When I'm fairing, I often close my eyes and see with my fingers. You will learn to see and feel.

Looking good Michael.

One of the areas I didn't pay enough attention to during hull construction is the fairness of the curves at the sheer. It was close to the floor and the natural uncomfortableness of working down there made it easy to overlook this. I did try to spot unfair lines, but there are a few small flat areas along the sheer line that I am going to have to take care of when I get to fitting the deck. Fortunately, they are not very big, but knowing they are there always gives me pause.

Not gonna forget the limbers in the floor battens this time.

Very easy job with the router.

Very precise limber cutting technique, well done. I use the nose of the belt sander to make my limbers.

Very nice Michael,

One suggestion learned from my own experience with these same cuts at the transom. Glue is going to get in there and is a real bear to clean out, so try o figure out some way to mitigate that. Be careful here because placing something in there to prevent the glue from seeping through may be real hard to get out itself.

One possible idea, but please evaluate for yourself, line the limbers with masking tape before applying the planking. Then get under there before the epoxy sets up and get the tape out. A PITA, but far better than letting it get hard before trying to remove it.

Just as point of reference, I heat bent a rat tail file and placed a handle on it. Then using that and a variety of power tools (when I could get access), I tried to clean out the limbers. Still somewhat rough inside, but it's as clean as I am going to be able to get it. Took me several days of effort and a lot of new four letter words. :D :D

Here's a couple of ways you can deal with that. Leave something in there like a piece of foam while you are gluing on the planking. Or, what I did was to run a small piece of cloth through the limbers after running most of the screws in to clear any glue squeeze out.

I think this second idea of running a piece of cloth through there is a good idea as long as the epoxy is still fairly liquid and the cloth is strong enough. I considered putting in something (didn't consider foam) in the limbers, but was afraid that I would never get it out.

Regardless of the method used, the important thing is to get under the boat and get that epoxy out as soon as possible. Preferably before removing any other squeeze out. IN fact, if the weather is cool enough (i.e.not hot), it might even be worth it to add the screws in this area first, get under the boat and clean out the limbers, and then return to adding the remaining screws. This way you more likely to have the epoxy in a liquid state and it will be easier to clean.

I like Matt's cloth idea, too. Perhaps even something like a cleaning mop for a .410 might do the trick.

I know I'll have to get up under the hull as soon as the flooring is on. In addition to keeping the limbers clear, I also want to clean the squeeze-out along the floor battens. This was (is) an unholy mess on the Utility, and I don't want to make the same mistake on the Zip. I just hope I can do it without epoxy dripping all over me.

Just a bad thought. If you put Styrofoam in the limbers, then a little squirt of gasoline will melt it right out. Of coarse then you have napalm in your boat. :lol: :wink:
