Small progress daggerboard gunwales mast step partner

Ok!

I continue to slowly progress on the boat. I am really stymied by the fact that its been all of 0 deg. F (-18 C) here at the house for quite a bit now. The garage has been holding temperature at just under freezing. Im not interested in doing major epoxy sealing work in these condititions because: a) its cold, b) the epoxy thickens and is difficult to spread.

However, I can do small spot gluing jobs. For instance, I installed the mast step and partner yesterday:



My Step was placed in first (obviously) as a whole piece, as in the 6mm ply backing was already glued in position. The fit was relatively tight, but not perfect because my BHs are not exactly perfectly parallel along the bottom. Im talking a few mms here, but still. Anyway, when you drop something into a tight spot to be glued, pay attention as to how youre going to place it in and glue those places accordingly. To clarify: Dont put the glue on the location that is going to get scraped by the incoming piece, put it where it will be squeezed in so the glue remains.

The partner went in nice and simple, except I dropped it on my heater fan. My partner deviates from the plans as in it is two pieces, with the bottom piece extending underneath the seat cleat on BH2. This is for stability issues, I could twist the top of the BH with my hand. This partner makes it very burly.

Notice my heater and my brick compression system. Its a $12 heater I bought at Lowes. With a plastic sheet, temps went up quick.

Next up I screwed the gunwales into place. I didnt want to necessarily do it, but its almost essential.

The next picture illustrates a non-screwed gunwale. Basically, the flare from the sides of the boat in the stern and amidships is translated to the gunwale to the bow, where there is minimal flare, the sides are relatively straight. Only muscling the gunwale with my hands could I make contact. Not conducive to gluing, as you can imagine.

Storer (el designero) promised that screwing the gunwale would pull it in. I had doubts and didnt want to deal with it, but I tried. Working from the stern forward, I placed one screw in the stern, two amidships, and two right in the bow area where the twist was most apparent. I used the 1 1/4 screws with the ply pads from the bottom screwing event.

SOB, it worked:


Nice and tight, all pulled together. This makes me happy. All ready for gluing. Screws were hidden underneath the areas where I am going to place my inwale spacers. Speaking of spacers, all of them are cut, and I have marked where I will be adding them. I started at the seam between the two pieces of ply for the sides, one will join them at the top, then one will be place next to each BH sidearm, with BH3 sidearms getting two small ones on either side due to the fact that it does not meet the side near the top. Re-enforcements, if you will. I need 52 spacers for this scheme.

Next up, I glued my daggerboard together.


I precoated the sides to be glued, then made a thin epoxy mix with the filler, not too much since the wood had been run through the joiner. The typical GIS clamp scheme as seen below:

And were off to the races! Looking good. Looking good.

She arrives, one step at a time boys, one step at a time.

Oar Prototype 1

I lost power and internet for a bit during the big blow the other day, and never posted pictures of the oar. The following day I decided to shape the oar up. Using my plane, block plane, random obit sander, chisel, and wishing that I had a spokeshave, I went to work. In about three hours I got the below product. As you may notice, there is a kink where the blade meets the loom. Also, I screwed up the shaping a bit.



I mean, for a first oar done in three hours, not bad.

The blade is kinked to the loom most likely because each measurement station was taken off the edge of the board as opposed to off a theoretically straight line connecting the two ends. So if there was any deviation in the way the board has been originally cut (most likely) then the oar would reflect that in waviness-- and thats what happened. My next oar measurements will be based off a straight line down the board.

Second, I started shaping the oar without squaring it first. This would have been an easy endeavor, however I was excited to get started and planed the thing into an oval. If I had made sure all 4 sides were square, it would have been a circle.

The grip is also oval, I think it might be rough on the hands. I should not have cut it out in the blanks, and shaped it at a block, that way I could have made it a circle with a 1 1/4" diameter as opposed to the 1" it is now (a little small for me).

In the end, an easy plan, a nice looking oar, its light, and with the pine was easy to shape.

Prototype #2 is in the works. This too, will probably be a scrapper because I already cut out the grip and then realized the advantages of cutting it out when the blank was glued up.

Bottom trimmed centerboard trunk and bat house!

Today was a productive day, the boat went upside down and back again.



My friend Peter ambled over with his router. This, combined with a flush-trim bit for the router, is a fabulous tool at dissolving the extra overlap left over from the over-sized bottom. It was either going to be a hackfest at sawing/planing it off, or this. The router was mucho easy to use, I cleaned up the enter boat in mere minutes. It left a little lip, which was cleaned up by my handplanes. Long strokes parallel to the boat to get it close, and then the smaller block plane held at an angle to the hull to get it finally flush. This took longer but was enjoyable work. The boat got dropped once, and it was not any worse for the wear.

The centerboard trunk components are also all glued up, but in two pieces. They will not be glued together until the daggerboard is complete, and then I can appropriately take the down the spacers inside (made from daggerboard jetsam, hence same width pre-finishing) to match the daggerboard, plus 2mm for a cozy fit. The daggerboard is being worked on on the side... I think I have a tempestuous relationship with the board and Im taking it slowly.


Peter, while he was over, made a three chambered bat house for his own house. Hes hoping to attract a small colony of bats to summer with him in his moist woods. One brown bat will eat 500-1000 mosquitoes an hour (yes, read that again) and a large bat house could contain tens upon tens of bats if not well over a hundred. Thats a lot of mosquitoes that are going to bite the dust. Additionally, bats eat truckloads of insects that attack farmed crops, help in seed dispersal and some species can be key in plant pollination. Bats do not equal gross, bats equal important. In New England (and spreading south!) we are afflicted with "White nose syndrome" which is hacking away at our bat population. The more bats we get, the better off we all are.

Each chamber is 3/4 of an inch. There will be a plastic grated landing zone below the chambers. The box will be painted a dark brown, and affixed on his house. They like it hot, and hot it will get. Bring on the bats!
