..so it continues

What do you know, the bottom looks like it will fit. (don't look too closely at the edges)

Looking from the front at the fitted floor and inside of the canoe.

Does this look finished to you....you wouldn't believe the amount of work still to do at this point.

About here I was thinking I was on the home stretch.. Dream on!


After putting the sides together and joining in the floor sections with wooden batons, stainless screws and lots of waterproof wood glue, all that remains is to plane, sand and make the joints all look good with filler and sandpaper before painting.
Sounds easy doesn’t it?

This whole section was just one sentence in the plans but took many weeks to do.
Plane the edges to perfection…took a week. Sand the joints smooth as a babies bottom… another week.
I filled the many screw holes and fibreglassed the stem and stern posts* into the boat then discovered that fiberglass resin is not the right resin for the job.
The plans were a budget set and when I checked I found the resin they recommended is not at all suitable for wood.
In a panic I consulted the web forums… to find out that I had no option but to tear the fiberglass and resin out of the boat and start again… Easier said than done, I had to pry the edges up with screw drivers, tire irons and anything else that came to hand. (there was some hammering) Then I pulled the fiber glass off with pliers, it actually tore the surface of the wood off with the fiberglass and I had to sand it all smooth again in the tightest of areas. (another two weeks effort and a little weeping)
With the right shipbuilding grade Epoxy Resin and fiberglass cloth I started back where I had been weeks earlier by glassing the stem and stern posts* and refilling the screw holes and gouges I’d made removing the original dodgy fiberglass. (mutter, swear)
Making filler from sifted sawdust and Epoxy Resin** then filling every tiny hollow took another week. Filling the bits I missed, sanding again, another fill and another sanding etc.
It was about here that I learned just how hard Epoxy Resin actually is. It’s a mixture of several nasty chemicals in a two part mix that sets faster than you want it to, then continues to harden until it’s so hard you cant sand it…
It’s so damn tough that it blunts sandpaper in seconds…and I MIGHT have used a little too much of it and had to sand most of it off to get the smooth surface I needed. I ended up using two hundred dollars worth of sandpaper, boxes and boxes of the very best quality paper I could buy.

As an aside I bought over 50 new paintbrushes and used them all just once.
The resin sets in just 5 minutes and the brushes cant be washed clean. Cheap brushes loose bristles into the coating so you have to use good quality brushes. If it’s not hot you might get 7 minutes to spread the resin before you have to throw the brush and unused resin away, mix more resin and start again with a new brush and container.

*The wooden sticky-uppy things at the front and back where the sides join.
**The official way of doing it…can you see why I don’t work with wood? Dodgy stuff..

The six hour canoe

Notice not one but two fire extinguishers... Confidant wasn't I?
This is the offending floor section after the repairs were made and the holes were filled. Dont look too closely at the edges, my sawing isn't the best.



(This was a long project so you will see bits and pieces now and again for a while)
If it looks like something you might have seen on a waterway near you dont be surprised, it's an old American design.
Reputedly the Six Hour Canoe can be built in just six hours... if you’re a ham fisted, rough as guts bushy who doesn’t care how it looks or how long it lasts.
But I tend to get a bit carried away with projects like this.

I was feeling a bit jaded and needed something new, something different.
It’s somewhat well known that the only thing I can build from wood is a decent fire, but what else would you expect from an ex-boy scout...

So what else would I choose but to make a wooden boat.

I’ve had printed plans to make the canoe for nine years now and thought it was just about time to actually make it. As I started I thought it would be easy enough and I could bore you with all the details...but that’s not what my blog is about.
Instead, I’ll tell you about the things that went wrong, and the things that went really, really wrong. (laugh with me now!)

First up you mark up two eight foot sheets of thin, flimsy ply wood and cut out the shapes, remarkably, this went well and I ended up with four bits that make up the sides and two more bits that joined together to make the bottom.
Joining the two side bits together went well enough, lots of glue, a thin cover plate of ply and clamps to hold it all together while it dries, but just where do you join a floor that measures out to 16 feet?
I decided to sweep the cement driveway clean and use that to lay out the pieces nice and flat, again lots of glue, a cover plate of the same marine ply and a big stack of bricks to weigh it all down. Clever eh?

Well, not really, you see the next day when I removed the bricks I found I’d glued the canoe bottom to the driveway and I couldn’t get it up, I had no choice but to use a power sander to slowly sand away the quarter inch thick joining ply. Eventually I was able to lift the sides one bit at a time with only a little damage.
I started gluing again and eventually ended up with all the bits ready to turn into a boat…


The sides came together rather well eventually. This stage took weeks as the stem and stern posts as well as the middle joints all had to be planed exactly to size and shape before I could put it together.

These pics were taken in my old cramped shed before it was torn down to make way for a new much larger shed. Now I've got room to swing a cat...if I had a cat.

I've been busy

The beginning, the sides cut out and clamped and glued together.


The hull together, glued and ready for Epoxy coating.


Looks nice in this one does it not? Three coats of Epoxy coating to waterproof the wood forever. (so the story goes)


Two more coats of Marine grade two pac primer.


..and here we are now. Ive had second thoughts about painting it Stark White though.. Even on this cloudy day it's still too bright to even look at...and this is only the dull primer. Im not bad at spray painting so it has quite a bit of gloss off the gun but nothing compared to the gloss it will have in two pac hi-gloss.


I’ve been building a boat…more about that later. (slight overstatement…it’s a canoe)
I started at Christmas time and fully expected to have it in the water by now, but living in the middle of nowhere has slowed me down somewhat, it takes two weeks to get anything I order. Run out of stainless screws…two weeks, need a bit more Epoxy…two more weeks..
During the process I’ve learned many new terms…tradie things like Bow, Stern, Thingamajig and Whosiwhatsit (official nautical terms)
I learned the finishing steps, the hole filling, sanding and finishing is called ‘Fairing’ or ‘Making Fair’. (not that I’m quite there yet)
I had some major work done on my house a couple of years ago and I learned many things...like ‘complete price’ does not mean it’s actually the complete and full price of the job and the process of hole filling, straightening things which should have been straight in the first place and finishing and sanding is called ‘Making Good’.
I’ve had some experience in the steel industry and the bringing together and joining of two parts of steel is called ‘marrying’, you bring in one part and marry it to another permanently by welding.
I’m thinking in this day where marriage is anything but permanent this misnamed procedure needs to have it’s name changed…I’m thinking it should be called ‘Partnering’. The bringing together and welding…for a while.

Just a thought!
