Every now and then I get some reports back from home builders. Here is one of them from Australia. He didn't write much but he did send a photo.
And a video link: http://www.youtube.com/watch?v=WaIx16cI4cM
A drill press is used to drill the holes. I am running the bridge along a fence to ensure that they all line up properly.
Masking tape is used to protect the soundboard finish from the sanding that is being done in the pace where the bridge will be glued. This location is VERY carefully identified.
The props that are inside of the guitar enable me to simply use these cam clamps to glue down the bridge. Without the props the soundboard would never be able to take the pressure. Of course, the better the fit the less clamping pressure is needed.
And this is how it looks.
The end of the fretwire is cut to allow it to overlap the fingerboard binding.
On this build I wanted to try epoxying the frets in place. The fingerboard face is first coated with wax, then the fret slots are filled with resin..
The frets are placed into the slots and clamped down.
As the fingerboard face was waxed the resin is easy to remove. The frets require only the basic dressing and we are good to go.
And it looks like this.
Lest anyone think that everything goes perfectly as planned, these are the pieces that didn't get onto the guitar.
The back binding at the heel can be done any number of ways. Torres often mitered them into an extension of the back that is glued over the heel. I forgot to leave the back long enough to do this, again, so I had to cut the miters into the binding and fit a piece of wood fit. I chose a piece that matches the back wood exactly.
And it looks like this.
These are some of the tools used to prepare the binding rebates.
This is the binding rebate ready to receive the binding, which on this guitar will be a simple walnut line.
The Bison bone worked out really well, the wall of the bone is nice and thick making it easier to get usable pieces from it.
I could have made much more, but for now I will content myself with making just as much as I need right now.
Which is a good thing because I need to make new outside gunnels.
Because this is all that is left of the old ones.
From the outside after grinding and sanding the resin residue. There is still some resin staining of the wood, but that won't affect anything. There were a lot of loose tacks on this canoe and I had to go over every single one to drive them tighter, and added or replaced those that stayed lose. Very tedious, there are hundreds of tacks!
A nice shot of the original 1948 decks of this canoe. You can clearly see the camber on the top as well as the undercutting of the inboard edge typical of early Chestnuts.
The ends of the gunnels needed some repair work. They weren't rotten and falling apart...yet, but there was some splitting happening along the line of screws.
In order to glue the bridge later I have to brace the soundboard. Typically clamps are fitted in through the soundhole, but with the Tornavoz in place this will not be an option. Each prop has a string to pull it out with. It is essential to remember to secure the strings out at the soundhole in order to pull them!
Now the back can be glued on.
The copper has a nice glow when viewed through the soundhole.
After it dries I cut it down into even more manageable pieces. Now I study these pieces to see how to best further process them.
And this is the result. I have many more pieces that I can cut out of my bone supply, but for now I will content myself to my present needs of one tie block cap, one saddle, and one nut.
After about 20 minutes of generous steaming they are ready to bend around the canoe to take the correct shape. They get bent at a section of the canoe that is just slightly smaller than where they will be installed to ensure a proper fit.
After they cool, the old broken ribs are removed and the new ones put in their place. At this point they are just clamped in place.
There is a lot of open space here where the planking is busted out, so a batten is clamped to cover a number of ribs to keep them all lined up.
For that I need a little help. Patou loves the fresh meat! Good thing because there's still lots left, but she's making progress.
The bridge as it looks now, with a little CA (cyanoacrilite) flooded on the fill any small pores.
Now I am ready to close the back, fret the fingerboard, glue on the fingerboard and bridge, binding, finishing, etc...
