Stern looks.

Back to the boat, I've been sidetracked with talk of bikes and bargains.

Chris came over on Friday and we took on the challenge of constructing the Sternpost. It was not straightforward as the parts list had us buying a piece of wood that was just too narrow to follow the plans. We are now confident enough to take these challenges in our stride.

The picture to the right shows the three pieces of wood, glued and ready to be cut. If you look closely, you can see the shape of a sternpost drawn onto them. Experience has shown that while my skills with a jigsaw are good, they are not quite good enough to cut a straight and true line in at 28mm block of Fijian Kauri. Does anyone have a band-saw ?

When we get one (a band saw), we'll cut this strange bit of geometry into something resembling a stern post.

Bargains,Bikes and Boats.

You'll have noticed a theme, I like bargains, bikes and boats. For instance, I fell off my bike, going to boat loading and couldn't build my boat. Unfortunately I'd got a bargain on my insurance, so the excess was a whopping $1,500!

Spotting my weakness for a good deal the bike shop have used the other $5,000 the insurance company were paying to make me an offer I can't refuse on a new Triumph. Instead of paying the $1,500 for the excess, I just have to part with another $2,000 to ride away on this brand spanking new Thruxton Special Edition (it's white, not red, apparently that's special).

Not one to pass up a bargain, I had to say yes.

I am not sure if I actually want it, and I did kind of like my old bike, despite it's attempts to kill me.

Anyway, this is the new bike, it's called a "Cafe Racer", I think the idea is you sit in a cafe drinking coffee, talking about racing whilst looking at your bike.

Oh, Chris and I have set aside a couple of hours to work on the boat tonight, we'll be fabricating the sternpost and admiring my spokeshave.

Transom.

I had a great joke about Yorkshire kidnappers lined up, but you wouldn't get it.

Instead of sharpening my new Spokeshave and No. 4 Plane, I decided to have a crack at shaping the transom.

It's been a drawn out process..

Firstly, from the parts list, buy a nice piece of hardwood, Mahogany in our case, that appears to be far too small for the job in hand. Secondly, trace out the shape of the transom from the half a transom on the plans and, using all your spatial skills, work out a way to cut up the undersised plank to fit the transom.

This appeared impossible at first.

Thirdly, glue the resulting three pieces together to make a shape losely resembling the transom.

Lastly, set to with a jigsaw, a sanding block and a chisel.

It's not finished, and needs a little more fine work, but here's one I prepared earlier.

At this point I would like to give a huge plug to West Systems epoxy, the picture above is of three pieces of wood glued together. If you can see the joins, I'll buy you a pint.

Nerdy Interlude for the Few


A spokeshave is a tool used to shape and smooth wooden rods and shafts - often for use as wheel spokes, chair legs or arrows. It can also be used to carve canoe paddles.


Spokeshaves can be made from flat-bottom, concave, or convex soles, depending on the type of job to be performed. Spokeshaves can include one or more sharpened notches along which the wooden shaft is pulled in order to shave it down to the proper diameter. Historically, spokeshave blades were made of metal, whilst the body and handles were wood. An early design consisted of a metal blade with a pair of tangs to which the wooden handles were attached. By the twentieth century metal handles and detachable blades had become the most common.

$40 !! Did I hear you right? I paid $50 for them, are you trying to ruin me!

Haggling, I love it. I make a point of haggling over everything I buy, I will haggle over electronic equipment, bikes, holidays, anything. My friends suggest it's to do with my Yorkshire heritage.

I was driving back from Lyall bay earlier today and noticed a second hand shop. I asked if there were any second hand tools. Indeed there were. I asked the helpful shop assistant/owner if he had heard of a spokeshave. So far only Chris and my old man seem to know what one is. "Oh yes" he says, I have an old one out the back". It's a bit blunt and a bit old fashioned, but it looks the part and I can sharpen the blade.

"How much"  I ask..
"errrrr, $10 ?".

What I really need, I point out is a No. 4 Plane, Stanley preferably. "Oh yes he says I have one out the back", again, a bit blunt and old fashioned, but it's reassuringly heavy and looks lovely.

"How much" I ask.
"errrr $35"
"$40 the pair?" I reply
"Done!"

I am very excited to get these tools home and sharpened and oiled. I think I have crossed some weird boundary.

You've been Framed.

And for those who are still interested in the build process, and would like to see what my garage looks like with the upside down boat frame in it.. Here you go. The time spent making sure the strongback was straight and true really paid off here, we were able to mount the moulds directly onto the strongback. The various supports are the result of different approaches to getting the moulds vertical. We settled on the angled cross brace approach seen on the leftmost three moulds. If you look carefully at the table with the circular saw and router - there is an empty pint glass with an electric jigsaw in the foreground. A potentially lethal combination.


It's not warped, it's taken with a wide angled lens to get it all in. This is the strongback and the moulds. 


Another Milestone

It’s coming up to 2 months since the kit arrived and we have at last made a couple of pieces that will form part of the boat itself. Plus we have all the bits to be shaped to make the rest of the hull.


We have been inventing techniques or adapting the skills handed down over generations to meet each challenge. Sadly, these skills come mainly from Joe’s Dad, so we are likely to be skiffing a massive egg rack down the Waikato in March.


This may not sound like spectacular progress, but we have a growing confidence in our decision making, as we have taken plenty of time over every single step of the way, never doing anything in haste and being careful to compensate for our natural aversion to a meticulous approach. The fact that we only get to work in periods of about 2 hours at a time is frustrating, but also means we have plenty of good reflection time.


Despite the temptation on occasion to enlist professional help, we have ended up tackling some of the trickier bits ourselves and discovered that we haven’t done too badly. It may seem trivial, but learning to map our plans onto the wood (using carbon paper) and then cutting a perfect shape with a jig-saw, was a major triumph.


What we have learnt:


  • Craftsmen are not communicators – the notes and instructions that came with the kit are not written for novices. We have found that they do begin to make sense, however, once we are facing a particular problem.
  • Don’t trust the detail – some of the measurements are plain wrong. Mercifully, it is usually obvious.
  • Listening helps: Joe and I often approach problems from different angles, but because we have (surprisingly) respected each other’s views, we have usually ended up with a good ‘third way’ (thanks for the idea, Tony, where did you borrow it from?).
  • Wood is expensive, so planning is very important.
  • Joe’s home made lager is lethal.
  • Brendan has the largest collection of useful tools in the known universe.

I am very excited at the prospect of, very soon, cutting out the planking. Worrying, isn’t it?
