Progress on SEI and a really good evening out

Ive been working away in the shop, fitting the seat tops and filleting them, turning the offcuts into doublers under the edges and sanding out the odd dribbles of epoxy,  read on.

Blog 4 September

Its getting close,  today I fitted the forward seat top.   Tis is in two pieces joined down the middle and glued in to form  to form not only the seat but the top of the forward bouyancy tank, as well as bracing the mast box.

 Filleting, the white stuff is a low density filler from Epiglass with a little cotton mill fibre ( glue mix) mixed in, thats for strength. The brown is Microballoons but underneath that is a smaller fillet of straight glue applied about 6 hours before.  

So that’s done, yesterday I fitted the doublers under the edges of the center thwart and the after seat ( which should be referred to as “Stern sheets” but I’m not that “correct” in my terminology).  These doublers make a big difference to the feel of the boat, stiffening the overhanging edges of the seats considerably as well as giving them a much more “solid” appearance.

These adoublers re made from the scrap left over from cutting the big parts, there wont be much more than kindling left when I’m done with this project,  successively smaller parts get cut as the project goes on,  so the scraps get smaller each time around.

Stern sheets, the doublers sitting on the seat  above where they will be fitted underneath the overhanging plywood seat edge.

Center thwart.  This is a great way to use the offcuts from the planking, makes a much nicer job of the edges of the seat. Next job to do is to glue them in, then round them off.

Forward seat tops to come next.

So tomorrow its at them with the angle grinder and sander to finish off the endges, round them over and fair them.  Then some filleting, more sanding,  and then its time for paint.

I must say that the Fein Multimaster is an amazing tool for sanding fillets, the point of that triangular sanding head with 60 grit paper on it does a very good job, effortlessly and quickly.  I love this tool and would almost own it just for that.

Paint, the outside looks good,  two coats of primer, and two coats of  satin finish paint looks good, so tomorrow I’ll be splitting the white between two containers and pouring a little of the dark green into one to get the pale green for the interior and then start swinging that paintbrush again.

Tonight, my friend and next door neighbour Emily Scott sings.  She has won a scholarship to the UCLA School of Music where she will study in the Masters classical voice program,  this is seriously top level stuff!  I’ve been to a couple of performances and she’s got me converted to Opera.

Tonights performance is a fundraiser, she’s got to get enough money together to live in Los Angeles for two years to take up her scholarship, and I’m going along.

We’ve had shared dinners, helped each other out some, and enjoyed each others company.  I’ll miss her, all the very best Emily.

Here’s her facebook page, well worth a look.

Time I got myself tidy, don’t need the black suit and tie but epoxy and paint covered overalls wont quite cut it.

( I went, full house, I listened, I enjoyed the concert immensely)

SEI afloat

Left to right. Blair, Paul and I about to pick her up and drop her in the water.  The designer is always a bit nervous on launching day. Float would be good, up the right way even better. 

It was a cool, grey and windy day, but the estuary is sheltered so there was not much in the way of waves when Blair, Paul and I walked the little boat down the ramp and into the water. She’s quite light at 76 kg, I can lift her on my own,  there would need to be a darn good reason for me to do that though but it does mean that handling her on the ground is easy, to pick one end up and drag her, or lift her around is easy.

I name this ship SEI.  May good luck  go with her and all who sail in her.

There are strong tidal currents here so we’d chosen to launch at slack water. We slid her into the water just before high tide, I shipped the oars climbed aboard and away.  She’s stable, steady enough to stand up and move about in, rows very easily leaving a particularly flat wake, and seems well balanced in a cross wind.

Ill get more pics when there is some light to show her off. In the meantime, check out the video on the link below.

I’d chosen 2.4m oars (8 footers) rather than the theoretical best length at 2.65m (8 ft 10in) so they’d stow easily out of the way of all the activity when sailing, SEI is after all primarily a sailing boat and when sailing the oars at this length will be stowed blade forward into the bow, with the handles out at the ends of the center thwart.  Out of the way, easy to access, and secure.

She is wider than most pure rowing boats, even with the oarlocks fitted inboard as far as possible on the gunwales, shes wide, that’s where the stability for sailing comes from, that and the fact that she’s wider in the bottom aft at the crew position than is usual in a double ender.  This is a “sailing” shape rather than a “rowing” shape.

Shes also workboat style, slightly chunky rather than graceful although she looks very nice from most angles.  I wanted her to have much more stability than other double enders of this general configuration,  that will help her sailing ability plus the seat and gunwale height is right for rowing.

She’s nice to handle under oars, tracks well, turns easily and is not sensitive to trim.  Even with a passenger aft she does not drag a wake behind, Denny and I want for a row up the river the following morning, she’d not been up there before and we covered about 4 miles out and back within an hour (the tide was helping, I was not out to break records).  Watched the sun come up, marvelled over the birdlife and the scenery up there.

Success, now I have to rig her for sail, that’s no big deal but I just couldn’t wait to get her afloat.

Thanks Emma, Blair,  Paul and Denny for the support at her launching.

Paul Mullings has kindly put together a video on YouTube that shows the action, Thanks Paul.

 Now Im having an acute attack of "empty workshop syndrome". Ah well, there is only one cure for that.

On the metaphorical road again heading for more small boat sailing adventures

The brotherhood of the travelling boots.

Its occurred to me that the hikers boots that I’m wearing have been to seven different countries so far, they’re good friends the two of them, get along well even though they’re almost twins. One of course is a lefty and the other a righty but even so they seem able to co operate and generally arrive wherever it is that they’re going at about the same time.

I’m on my way again, this time to Chile,  will arrive in Santiago in about 18 hours.

Right now I’m sitting in Auckland International airport, within a few metres of the Percival Gull aircraft that Jean Batten flew from England to New Zealand in 1936, setting a number of aviation records on the way.  That flight took 11 days and 45 minutes to cover a bit more than 14000 miles. 

I’m going to be travelling in an aircraft that barely resembles that tiny single engined spruce and canvas plane.  In fact it would be no real problem to fit the “Gull” into the cargo hold of the big Boeing that I’ll be imprisoned within for the 13 ½ hour flight across the Southern Pacific Ocean. We’ll be travelling at around 590 nautical miles per hour, how different it is from Jean in her little light plane t125 mph.  I bet she didn’t complain about the cabin service in her tiny cockpit .

Jean Battens Percival Gull airplane, as I write this Im sitting about 2metres away from the wingtip on the left of the picture, its a graceful little thing, but a real reminder of how much aviation has progressed since then, remember too that Jean Batten was with us until 1982, so most of this amazing progress has happened within the space of a long lifetime.

This trip I’m making is by the way the longest uninterrupted stretch of ocean that there is north of the five great capes about twice the distance that it is across the North Atlantic from USA to UK.

Which brings me to why I’m travelling.  I’m to meet up with friend and co teacher Howard Rice, and we’re going to be setting up for the big voyage of exploration that he is undertaking next southern summer.

That voyage, in a modified SCAMP, all of 11 ft 11 in long ( 3.575M ) will leave from Punta Arenas in the Straights of Magellan, carry him out through the channels and straights into the Pacific where he’ll turn left, and head south toward Cape Horn.

That latter is not necessarily the objective of the voyage, but rounding “The Horn” is a possibility.  The real purpose of the voyage is to explore the least populated and most rugged coastline on the planet,  riven with steep sided fjords, many with glaciers at their heads, backed by mountains, many un named as yet, and battered by the incessant gale force winds of the Roaring 40s this is an extraordinary place, and one which Howard will be exploring, and documenting.

There will be cameras on the boat, as well as within his support crew back at Punta Arenas, there is already some video “in the can” and the intention is to make a comprehensive video of the voyage, a video which will be available to anyone wishing to see the grandeur of the wildest place on the planet from the viewpoint of a small boat sailor.

There is more on the boat and the voyage in Howards Facebook page here

Yes it costs by the way, and if you’d like to support this, check out the directors website here. http://www.below40south.com.  There is also a lot of information on the voyage there.

  Any donations would be very gratefully received, we’re covered for the actual filming but the production costs will be significant and even a small amount would help to get what will be one of the great small boat adventures out where people can share it.

So I’m sitting here in Auckland airport with several hours to wait until the big silver bird roars down the runway and turns out eastward over the sea.

Its not boring, I’m in a quiet corner upstairs, this is one of the better airports that I travel through, and I’m alongside a glass wall where I can watch the people flow like a gently stirred anthill.  It’s the arrivals area just below me, and there are friends, parents, siblings and visitors arriving, it’s heart warming watching the enthusiasm and emotion with which they are being welcomed.

But I’m going the other way, I’ll be among that crowd downstairs in 20 days.

A tiller for SEI

Laminating a curved item such as a tiller is one of the more rewarding jobs. A gracefully curved and very strong tiller with the gluelines accentuating the curves can add a nice touch to the boat, and its not hard to do.
Heres "me" making a tiller for SEI.

A tiller for SEI.

Now SEI being a double ender has the rudder a little further away from the skippers hand than is usual in a transom sterned boat so needs a longer tiller than would otherwise be the case.  That’s consideration number one, consideration number two was the shape, then consideration number three was what to make it from.

I didn’t have a suitable piece wide enough to cut the shape from in one piece, and friend Bill Simpson had given me an interesting piece of wood that had come from a big shipping pallet.  Who knows what it is, but its light, tough, is close grained and glued well.  It is not so easy to work with a hand plane, the fibers being long and tough don’t cut so well, but wood like that generally machines well, so I figured that being much too narrow, I’d laminate the tiller.

The tiller slot in the rudder stock ( rudder head in some languages ) being 27 mm wide I sliced up the wood with the sawbench, cutting first to make two 35 mm pieces out of the 70plus wide piece to give me room to plane it down to the 27mm width, then splitting that into 5mm lamells.

I took a piece of scrap ply down to the boat, propped it in place and drew the shape of the tiller thereon.  Reproduced that on the plywood floor in the boatshed, screwed the laminating clamp blocks into place and mixed up some glue.

There is not a lot of curve in this tiller, I like the “hand end” to be about 100mm above the knee when sitting at the helm, and the final position will be set by shaping the haft end where it sits in the tapered slot in the rudder stock.  So with only a gentle curve to accommodate this was an easy job to lay up and clamp.

The shape drawn on the plywood boatshed floor, and the clamping blocks screwed in place, the lamells are laid out in order. Note that the tiller is much deeper at one end and finer at the handle end, so there are more layers at the "thick" end, no need to have it the same depth all the way.  Im read to start applying glue.

Glue applied, priming the one and laying the glue on the other for each layer, the whole set was layed on the supports, then clamps with little pads under the clamps feet were fitted, just lightly, then gradually tightened to bring the 12 lamells into the curve. Easy peasy, a little at a time but with that many layers in there the amount of force applied between the many clamps is considerable, so it pays to just be patient, a little at a time works well.

All glued, and clamped up. Its time to go and do something else for a day or so.

Next day with the glue all set, the first job was to plane it to the correct thickness, so it was with a scrub plane, that’s an ordinary block plane, in this case a Stanley number 4, with the blade sharpened with a round in the edge so the corners don’t dig in, that I cut all the glue squeeze out away and scrubbed that side down to fairly flat.

The edges of the layup don’t match perfectly so there is a bit of material to remove, that’s why the lamells are 35 mm for a finished thickness of 27 mm.

All good, now its time to get all the bumps off and the blank planed down to the correct thickness.

With one side fairly flat and the bumps of glue removed I put the blank through the planer, flat side down and the other side getting planed down.  Three passes got it down straight and true, then flipped it over and trued up the side I’d hand planed.

In action with the scrub plane. Note that I have a heap of these Stanley number 4s, 9 I think, and several have their blades ground for particular purposes such as this.  I watch the shelves down the back of a couple of favourite junkshops and if I see one at under $20 Ill buy it, do a little work on it it if needed, and put it on the shelf with its brothers and sisters. Youd be surprised at how often I use more than one on a job.

Careful measureing, still well over the 27 mm I needed, so more passes through the planer, taking care to remove a few little defects on the way, and when it was close, I tried the fit in the tiller slot, a couple of very fine cuts in the planer and I was happy with that.

Then the shape was drawn on one side of the tiller blank, and the shape cut with the bandsaw, in fact careful use of a jigsaw would have done it, or even a Japanese razor saw using the ripsaw side of the blade http://www.duckworksbbs.com/tools/pullsaws/index.htm

Either  of these would do fine as long as attention was paid to keeping it perpendicular to the surface being cut through.

Action with the router, that edge near the power tool is now nicely rounded over, it took about 30 seconds.  Note that I was given that old beast of a router by my elderly uncle, he thinks its probably 40 years old, today youd get one like that for $10 or so and it works just fine. Its much simpler than todays flash harry ones, and I much prefer it for heavier use. Ive a little laminate trimmer for very light work but this is the workhorse when there is serious stuff to do.

With the shape cut, the edges were trued up with a random orbit sander,  the piece clamped to the edge of the bench then a router with a 12mm radius bit employed to round the edges. Remember not to round the haft where it fits into the tiller slot, that just needs a very small round with sandpaper.

With some light sanding, its done.  Looks sweet, looks much harder to make than it really is.

Just a few finishing touches to be added. I cant wait to use it for real.

I’ll varnish it, apart from the oarlock support blocks it’s the only varnish on the boat, it adds a nice finishing touch.

I’m not so far away from sailing SEI,  have to finish the rudder assembly, turn some wooden end blocks for the carbon fiber boom and yard, then rig it, and I’ll be at the mercy of the winds.
