« Part 14: You would think "Don't get any on you" would be an easy bit of advice to follow... Part 15 of Maybe the beginning of a larger project series Part 16: Don't run with scissors! »

Today was a pretty productive day. I spent about 4 hours epoxying the joints and sides. The puke mouse Paul (shipwright) describes in his blog worked exactly as advertised. My technique requires some refinement but it sure did a tidy and quick job of laying down a fillet. I watched Sam Devlin’s primer on stitch and glue and he shows the filletting going between the stitches. I now see why. I broke 2 or 3 getting the stitches out. I will have to try the suggested heating of the wire and then drawing it out.

I measured out where the bulkheads should sit and discovered that even though I’d faired all 4 identical pieces at the same time the two bulkhead pieces did not sit properly inside the hull. I am marking the differences and planing the pieces to fit. My LV block plane has been my go to tool for this project. I spent about an hour doing that yesterday evening. So all told I spent the better part of six hours on hull 816 today.

While I’m doing all this other stuff what I’m going to make the rudder ‘hinge’ out if. I have sone blocks of that high density plastic that may make a good non rusting self lubricating hinge. I’ve got to figure out what I am going to use for the shaft part of the hinge.

At first the epoxy was intimidating but the more I lay down the more possibilities keep cropping up. There are a couple of projects that have popped into my head because of the ease of use and versatility of the epoxy. One thing that was sure apparent is how sensitive the epoxy is to temperature. The 206 hardener I purchased is the second slowest hardener West has and as it was probably 5° to 7°C warmer than the first day and the epoxy started to set up noticebly faster. It also went from tacky to semi hard a whole lot faster

The shot below is where I left it at the end of the day. You can see the inner bulkheads in their approximate positions. The starboard one is close to fitting properly, the port one has not been touched at all.

One thing epoxy is not well suited to is killing wasps. I am working away in my shop when this black wasp flies by, settles oh so briefly on the epoxy, realizes its a dangerous environment and immediately tries to take off and flips wings down in the fresh glue. He manages to get back up right but by thus point I figure if he actually gets free he’s gonna be made so I whacked him with nearest thing handy…my epoxy laden brush…thoroughly coating the poor creature in glue, I then flipped him to the ground and put him out of his misery. The other thing I learned about epoxy and insects is….DO NOT slap mosquitoes in you hair with epoxy covered gloves! I hadn’t even realized I had done that until I got back in the house. Fortunately I have short hair and as it had hardened a bit I managed to get the clump out of my hair:-) Lesson learned!

If you use black tie wire you can actually kink the inside bit into the angle of the corner and epoxy right over it. You can heat the wire and remove it but if you are epoxying over it, just sand it off and leave the little piece that’s left. It won’t rust on you.

The wasp story is fun. I built a stitch and glue boat once in peak horsefly season and can testify that they work quite well as a filler in larger epoxy fillets.

I managed to break off all but two of the remaining stitches, so I’ll follow your advice Paul and just make sure the ends aren’t proud of the wood and just seal them in. I think I saw the West 40n large annoying insect filler, I knew I shoulda added it to my cart LOL!

Thanks Mike, I am enjoying the build and I hope the blog is readable. Didn’t make too much progress today, spent a bit of time sanding…I am planning on tomorrow being a better day.
