Guitar #30/3

Assembling the box

After days spent reorganizing the shop, which had become next to impossible to move in, I am back at it. Yesterday I bent the sides ( also called ribs) and assembled them to the end blocks. The end blocks had been made some time ago. These determine the rib depths and the correct angles at the four intersections where the ribs join the top and back (neck and tail). The first step was to trim the blanks to just a bit wider than the maximum finished width (depth of the body). I trimmed these to 104mm – the maximum depth being 100mm. That left me room to trim after assembling the ribs and blocks before attaching the plates. The next step was to mark each rib with yellow pencil at 25mm intervals. This is a great aid in checking progress against the pattern, which is also marked at 25mm along the outline. While I did this I had the bending iron heating up.

Bending walnut is not very difficult. You keep it wet and hold in one place for a few seconds, pressing gently, then move a centimeter and press some more. The hot metal pipe dries the wood in seconds and it sizzles when it contacts wet wood. No sizzle means the wood is dry and has to be wet again. I start at the waist, then do the upper bout, then the lower. It takes constant small adjustments but with patience it can be made to follow the pattern shape quite closely. Once it is close enough it gets clamped into the mold, where it then dries and takes the shape in which it is clamped.

Once both ribs were bent and dried in their final shape I trimmed the ends and assembled the pair of ribs into the mold, checking that the joints met tightly and along the centre line of the guitar. Then I glued in the end blocks. The easiest way to do this is without the mold, just one end at a time, clamping the ribs onto the block. Once both blocks are done then the assembly goes back into the mold and is clamped with spreaders.

The spreaders ensure that the ribs are in the right position for attaching the plates. Just a bit of pressure is enough to keep the ribs pressed to the sides and ends. I assembled the back plate first this time. I wanted to try a different method of gluing in the linings. First I glued the back to the blocks, neck and tail. Then I put the whole thing on its back and clamped the back plate here and there to the ribs, so it was tight. I then glued in the kerfed lining strips, rubbing them to increase the initial tack, and holding them pressed into place for a short time. In a few places I resorted to putting pressure with a re-purposed chopstick and a clamp. This saved me doing two steps, where the linings are first glued to the rib, after which the plate is then glued down onto the linings. This way I was also able to avoid having to cut pockets in the linings for the ends of the braces. Instead I simply glued several teeth from the kerfed strip at each brace. This will be sufficient to hold the brace end tight. Note here that I first trimmed and fitted the back plate to the ribs before this procedure.

After the back plate was done and the glue set, I then fit the top plate to the ribs. Then I glued the linings for the top in place. Since my main top x-braces are tapered to zero they require no pockets in the linings, except for two which hold the upper face brace. These will be cut before the top is glued on.

Guitar #29/1

Martin O15

I’m building a guitar for a friend. It will be based on a Martin O-15. It’s small, about the smallest full size guitar Martin ever made, but it has a great sound. The 15 series were all mahogany, and had minimal trim.
The one I’m going to build will be made of walnut, with a cedar top. It will not be a flat top, but will have an arch. This will require a tailpiece and a floating bridge. Martin made some like this around 1932, the R model, but they were short lived.
So far I’ve traced the body shape of an O-15 I borrowed, and made a paper half template. From that I traced a full size body outline on Bristol board. Next I drew in where my braces and the sound hole will go. Then I made a body mold from 8 pieces of 9x22x¾” plywood. This involves band saw cutting, drum sanding, and finally routing the seven rough sawn shapes using the master as a router template.

On the Road

1-sk003

Harris Beach, Oregon coast

Summer behind us here, with two weeks vacation to spend we set off on Highway 101, down the Pacific Coast, bound for California. Like all trips, this one was a perfect opportunity to do some sketching and scour the thrift and antique shops for cool stuff (typewriters and old cameras). 101 is a marvelous road, full of stupefying vistas, interesting towns and endless campgrounds.

After 2 weeks of browsing, it was on the last day of the trip that I discovered two typewriters that I could afford. The poem was typed on the one in the picture. The typewriter came with the previous owner’s name on it. A Google search revealed that she died over 10 years ago, but her husband only died last year. So I surmise that the typewriter was disposed of by estate sale, hence ending up in an antique mall.

My first trip down 101 was about 25 years ago, and I thought it wasn’t very interesting. At the time I was fresh from the east coast and had been hoping to see a lot of quaint east coast villages. Now, many trips along the route behind me, I see it differently – an amazingly interesting and varied route. I can hardly imagine that there is another single highway of its length that offers so many beautiful landscapes and scenes as this one does. However, I have heard tell that US Highway 20, which happens to start at the intersection with 101 in Newport, Oregon, is a likely competitor. One day…1-sk004

The Huns are Back

We could use a laugh around here today… this is a storyline I’ve been using for my kids bedtime stories going on 30 years. This one is new, I wrote it for our annual camping trip. This is the first time I’ve illustrated a story.1-IMGP2158

PRINCE RHINESTONE AND THE HUN

By Donald J. Nathan
©2014
When Prince Rhinestone returned home after some years of fighting Huns, he had grown several inches, and needed new armour.
He paid a visit to his armourer, Sir Breakwind, to be fitted for a new suit, along with a matching sword. When he walked into the workshop, however, he was surprised to find that Sir Breakwind had gone out of business, and found himself smack in the middle of an auction sale.
“I say,” said Prince Rhinestone to no one in particular, “I say, what is going on? Where is Sir Breakwind and why isn’t he here? I want a new suit, and a matching sword!”
There were chuckles from the crowd and Prince Rhinestone looked around vexedly.
“Sold for thirty seven shillings to the man in the green pants,” said the auctioneer, slamming his gavel with a bang.
A short man came waddling up from the back of the room to the clerk and pulled out some coins from his purse. He dropped them on the desk, picked up a box of chain mail and turned to leave. Prince Rhinestone followed him out the door and hurried to catch up.
“Excuse me my good sir,” he said, tapping the man on the shoulder, “would you be so kind as to tell me what exactly is going on here?”
The man looked up at the Prince.
“Sir Breakwind, he’s gone out of business, your Highness. It’s a shame I say, but what can be done I asks you, Sir? It’s that new cheap imported armor what done it. Old Breakwind, he couldn’t compete with it, no Sir. Shame I say, damned shame.”
“Thank you my good man,” said Rhinestone, bowing ever so slightly, “and where does one find this new armor I pray?”
The man nodded his head to the side – “down that street, and round the corner in Highcastle, that new shopping street.”
“Never heard of such a thing,” said Rhinestone, walking away.
On his way down the street he noticed that many old shops he’d once frequented were gone, boarded up, with For Rent signs nailed to the doors. In all his life he’d never seen such a thing, and he was sorely puzzled.
When Rhinestone turned the corner onto Highcastle Lane his puzzlement turned to surprise to see a great crowd milling around. There were great heaping piles of goods for sale, and posters with words like “New and Improved”, or “Price Reduction”.
But there were no shopkeepers to be seen, only clerks sitting at desks taking money from people lined up with armfuls of goods. Noticing a large sign hanging from the ceiling with the word “WEAPONRY”, the prince worked his way through the crowds. There a young boy was arranging maces in a neat pile.
“Where is the armourer?” asked the prince.
The boy looked at him with a vacant stare.
“The what?” he replied.
“Never mind,” said Rhinestone, picking up a mace and swinging it around. “How much does this cost?”
“One shilling,” said the boy, “but if you buy one you can get another for half price.”
Rhinestone frowned. “Why would I need two?”
“I dunno,” said the boy, “everyone buys two.”
Rhinestone pulled out a shilling and handed it to the boy.
“I’ll just take one, thank you.”
“You have to pay the clerk,” said the boy, pointing to the lineup.
Rhinestone pulled out another penny from his purse and gave it to the boy.
“Here, you go pay for me,” he said, and turned to go.
“You can’t do that here,” said the boy, handing back the money, “you have to pay the clerk, that’s how it’s done.”
Rhinestone took his money and walked to the back of the line that said “EXPRESS – MAXIMUM FIFTY ITEMS”. An hour later he paid for his new mace and walked out of the store onto the street.
As he turned the corner an armed and dangerous looking Hun appeared right in front of him. He was huge, with great big blue eyes and a hooked nose.
“Take that,” said Prince Rhinestone, smashing the Hun with his new mace.
The mace gave a great clang, bounced off the Hun’s head and snapped in half. The Hun glared at Rhinestone for a moment and began to laugh.
“I bet you that was a cheap imported mace,” he roared.
Rhinestone looked at the broken handle of the mace in his hand, and nodded.
“Yes it was,” he said, disgustedly, “buy one and get a second one for half price.”
“You should have bought a second one, you fool,” said the Hun taking a swipe at Rhinestone with his sword.
Expecting such a response Prince Rhinestone ducked, but the Hun’s sword cut the head off an innocent bystander who had been hurrying by. It was the man who’d bought the box of chain mail. Rhinestone picked up the chain mail from the box and held it up to show the Hun.
“If he’d only been wearing this it might have saved him,” said Rhinestone.
“Serves him right,” said the Hun, “the world is going for shite with all this cheap imported crap.”
“That’s a good sharp sword,” said Rhinestone, “where did you get it?”
“Japanese,” said the Hun. “Took it from a dead Samurai. I’ve beheaded hundreds with this and it’s still sharp.”
“Thanks for the tip,” said Prince Rhinestone, “but I think I’ll stick to my sword. It’s Italian.”
“Hmmph,” the Hun grunted, “didn’t help those Romans, but too bad about that fellow. I don’t usually do that.”
“Hey, no hard feelings,” said Rhinestone. “Let’s go have a beer, my treat – what do you like?”
“If it’s cold I’ll drink it,” said the Hun. “Can you get a good Hefeweizen in this town?

the Caffeinated Photog

These were shot on some old Kodak Gold 200 asa colour film, with my Pentax ME Super. All the colour films seem to be coming out with a very narrow spectrum, and require a lot of shadow, highlight and/or fill light added. But the results are interesting. However, for this sort of home developing I would recommend medium format over 35mm. For one thing they can be scanned at a decent res and will give quite amazing details. The 35mm film needs high res scanning, and that takes a long time. These were scanned at 600 dpi however, which is reasonably quick.
