My big day

Today was quite the day. Im over my cold, as in, I dont feel like super-crap anymore, but my head and chest are still congested to hell and back. However, since Im slowly on the up and up, off to the basement for a little R+R.

Last night I realized that I had beveled the bottom of BH1 in the wrong direction. Today I fixed this by re-beveling it flat, and just leaving it as such until later. If I have to bevel it in the correct direction, so be it. Its only 2mm so its not too tricky.

Second, I found this:

Delamination in the ply on my Starboard bow, inboard. Approximately 4"x6" or so. Nothing on the "mated" side, the Port stern, so Im assuming it is only this piece that has the problem. I sounded it out with a pencil, and Ive got a good idea of its shape. I poured straight epoxy into the hole, then squashed it with bricks.

Third, I discovered this:


Thats my finger pointing at where the bow SHOULD be. OOPS. Im slowly coming along with the dreaded stem, and I went to match the stem to the bow and it came up a couple of cm short. Either my stem was wrong or my bow was wrong. I busted out the lofting map for the sides and for some damn reason, I measured 55mm from the end of the ply to the point of the bow rather than 55mm from the last 300mm mark. Damn, bro, good catch! So I re-marked the bow and cut them anew on both sides. The stem fits perfectly now, with room to spare for the bow knee.

Then, I got gutsy and ripped two of my cedar planks and and scarfed them for the chinelogs:

This is my scarf. Some of you are really going to hate this, but I eyeballed it on the table saw, and then planed them to match. Not perfect, but close enough for this amateur! I used a 1:6 ratio, so that would be 1 1/2" : 9".

THEN, I cut out the buttstraps and glued my scarfed chinelogs and my side together!


Here we are now in the garage. The buttstrap gluing kinda blew, I was by myself and I rushed it. I was sure I put on enough glue, but very little actually oozed out from underneath the straps. Im actually a little concerned I may not have put enough, but maybe I put just the right amount, I tend to go overboard with the glue. So well have to see about this.

Finally, I glued on a little piece of ply for backing on the transom for el rudder. Thats Spanish. That in itself was a mini-adventure, because the ply I chose for it initially starting sliding around after I glued it up on the old epoxy from the frame and the seat cleat. WOOPS. So I pulled it off quick, tore apart the garbage for an old jigsaw blade, and holding the jigsaw an inch above the ply ripped a small piece of one end so it could sit better between the frame and the cleat. Of course I got wood dust all over the backing, and I scraped it off, threw on some thickened epoxy, and called it good. I thought this would have been a simple operation, so I didnt wear gloves and holey moley my hands got sticky.

On a blog-related note, I am deleting the timing scoreboard from the blog. Its beginning to get inaccurate and more difficult to keep up with. Today I did a million things and Im not keen on attempting to figure out what was what. So maybe from now on just a tally total.

A note on tools

A few things on tools that I have found out the past few days.

A japanese pull saw is awesome. I doubted it at first, hemming and hawing for months before getting a small one-sides saw. A FANTASTIC PURCHASE. Versatile, sharp, easy to use, and precise. Practice first, because youll saw through something important quickly and without realizing it (trust me).

My random orbital sander was a $9.95 DEATH DISASTER I purchased at cheap-tool-emporium Harbor Freight. Its so frustrating to use I want to throw it at the cement wall. I will have to go buy a better one that actually secures the sandpaper.

Most importantly, I was perusing my jigsaw blades and saw something called a "scrolling blade." It was small and skinny. "Hmmmm, I betcha this is for going around corners a little tighter than the normal blades!" Hmmmm, I reckon I was correct... and this was after I cut the hole through the transom, BH2 and BH3. Boo me, for not knowing my tools. Again, amateur style is my building style.

Gluing BH 4 and some things I found out about gluing

Alright, Im a little frustrated at myself right now, because things are coming along nice, but not coming along like I want them too. Everything will be OK in the end, but it wont be as nice and neat as I would like to see, and thats aggravating. A lot of the mess stems from excess epoxy squeezing out and making the seams look all lumpy and dumb. A faster clean-up job before anything even begins to think about setting up would have saved me from having stupid looking frames.

First, Ive been having some problems at work that are pretty significant, and I wasnt as focused on gluing as I wanted to be or could have and that led to sloppy gluing work.

Second, I just dont have wood gluing experience. My epoxy/fiberglass experience is solely focused on my Laser, hull #194, from the early 70s. This boat has hit submerged objects, sandbars, docks, buoys, other boats, etc. at speed. Laser speed. Fast. Rig humming with 2/3 of the boat out of the water fast. Once, it fell off my car... while I was driving. Needless to say, Id just slop some epoxy on and keep going. Now that Im gluing together my wood boat, I cant be as messy, or at least, Id rather I wasnt as messy.

BH1 is messy but will be hidden mostly from view. BH2 is somewhat in view and the frames are going to visible, and its kind of messy. BH 3 could have come out perfect, but it looks messy too because I rushed and didnt STOP.THINKFIRST.NOTSOFAST. BH 4 came out really nice and clean, but the frame is mostly hidden within the rear airtight box, so no one will see my clean job! Dammit! Roar!

So heres a tip to you beginners out there: First, read all you can about epoxy. I have yet to find a nice primer/tutorial on wood gluing for boats, and that would have helped. The Storer forum, my thread in particular could help you out. Second, my biggest mistake in neatness is that I waited for the epoxy to firm up to a putty and then tried to hack off the excess. This is a mistake. This evening I glued BH4 together, let it sit for a few minutes to excess epoxy oozed out, and just cleaned it right up. Presto besto pesto yum done. A nice neat job. Why I didnt think about this 3 BHs ago, I know not.
