Sewing, or day 20

There's lots of information available online about sewing the skin on a kayak, but not a lot on sewing leather seats into them. The best information I was able to find was this video, and it's similar to the method I used.

I used two needles and a piece of artificial sinew about four times the length that I need to sew. In the picture below, you can see half of the thread hanging down below the seat. To do a stitch, I push the needle through just like you would a normal running stitch.



Below is the view from... well... below.



Pull the needle through and make sure both ends are tight. The good thing with the artificial sinew is you can let the needles dangle like this and they don't usually fall off.



Take the second needle and push it up through the hole that the first needle came through.



Once you've pulled it through and made sure again that both ends are tight, just repeat until you get to the end.



With the smell of leather and wood, and the sound of Don Burrows playing jazz on the stereo in the shed, I couldn't resist lighting up my pipe.

A pipe and a comfy chair, what more could a man want?



And the frame is officially finished.



This is what six yards of ballistic nylon looks like. I remember having to roll my bedding up like this when I was in the air cadets as a teenager.



After finding the midpoint of the cloth, it's layed out along the hull and a pocket, about four inches long, is sewn at one end to hold it in place. You then you slip it off, go to the other end of the boat and you have two choices. You can either a) pull the cloth to take out the slack, then make a mark about four inches in from the end and sew there, or b) pull the cloth as thight as you possibly can, make a mark at the point where the end of the boat is and sew there.

I got a little confused at this point and ended up combining both methods. After lying on the ground with one foot against a deck-beam, much to Donna's amusement, I made a mark in the right place and sewed the second pocket from that point in about four inches. Then I rolled up some of the cloth for a better grip, put my foot against the deck beam and pulled with all my might. The boat was creaking and occasionally lifting off the sawing horse at the other end, I was grunting and straining, and I still couldn't get the pocket over the end of the boat. I decided I was going to have to remove a few stitches, that's when I realised what I done wrong. It's not really a pocket you need to sew the second time, just a few stitches to hold the cloth in place. Once it's there you can let go and sew in a pocket.



Below is the first pocket on the bow of the boat, once I'd got the cloth pulled tight and sewn on at each end, and the boat was turned up the right way.



I then got out my soldering iron and cut off the excess material. In this last picture I've only removed the excess from one side. It was getting way past my lunch time, so I though I'd take a break. Incidentally, the soldering iron is only a cheap 45w one, but it did the job okay once it'd heated up properly.



Once I've trimmed both sides it'll be time to start the first line of stitches down the centre of the deck. I think I'll refresh my memory on the technique by reviewing Corey's instructions a few times first though.

Another 3 hours today, that's a total of 69 hours. I should do up a spreadsheet listing how long it takes for each part of the job, although I have seen one online already. I'll see if I can find it again and post a link to it.
