Polyurethane

In some ways, this is the most difficult part of making a harp. Up until this point, whenever I want to putter around in the garage there would always be something for me to do on the harp. Now I have to wait between coats of polyurethane.

The can of polyurethane says to wait four hours between coats, but that is NEVER enough. Not if you want a mirror smooth surface. My woodworking consultant, Heidi, always waits several days between coats. I've compromised for my own method. I wait 24 hours after the first coat, 72 hours after the second coat, and then three weeks after the third coat before tuning up.


Before each coat I sand the whole harp down with 220 grit sandpaper, then remove all dust and oil using a rag dampened with mineral spirits. Oil from my skin can affect the polyurethane, so it is important that once I start this process I never touch the harp without gloves on.


There are probably as many methods of applying polyurethane as there are woodworkers. This is the one I use: using a one-inch fine bristled paint brush and working one small area at a time, brush the polyurethane on against the grain, then smooth it in with the grain. That way I go over every area twice, ensure a thin coat, and catch any drips that might try to happen.

And there you see the result. Just look at that baby shine!

Once the polyurethane is dry, I can paint a design on the soundboard. First I do a line drawing with my drafting pen and waterproof ink. Then I paint using the same wood stain that I used on the body of the harp. Wood stain is a difficult medium to work with. If you try to paint over an already painted area, the fresh wood stain dissolves the older wood stain and forces all the pigment to the edges of the wet area. So you paint the dark areas first, then lightly brush in the lighter areas around them, trying hard not to bleed the new paint into the old. Of course I do use this interesting property of wood stain to good effect. I can create light colored veins in leaves by painting on a partially dry dark leaf.

Rebecca's Reviews: Indiana Jones and the Kingdom of the Crystal Skull

Harrison Ford: the man who can make badly written dialog sound good.

Good thing for Indiana Jones.

Our story opens with Dr. Jones being fired from his university teaching job because he helped a beautiful but evil psychic communist Russian lady spy steal space-alien remains from a warehouse in Area 51. Of course he was forced to do so at gunpoint by a squad of Russian soldiers, but in the anti-communist climate of the 1950's, that still leaves him under suspicion. I mean, any true red-blooded American would rather be shot than let the Russians have our precious space-alien remains from area 51, right?

As it happens, Dr. Jones is glad he doesn't have to teach classes for a while. Just as he's on his way to sulk in Europe he receives a mysterious coded letter from a former colleague who was hunting for a lost temple in South America. To further complicate the matter, the letter is delivered by a teenage boy on a motorbike, leather jacket and hairdo reminiscent of The Fonz, who claims his mother knows Indiana. And guess what, mom is being held captive by the Russians somewhere in the Amazon. Those Russians do get around.

Indiana Jones to the rescue.

The film had some clever moments, but much of it was re-hash of old ideas. Especially amusing was the way everyone looked so amazed as they discovered that the space-aliens had taught farming and civilization to the Incas or Aztecs or whoever they were. I mean, haven't they seen 2001 A Space Odyssey? Oh, I guess not. That came out in 1968.

I disliked the fact that so many people died horrible deaths in the film. It made it less fun for me to see extras lying all over the ground. Another problem I had was the teenage boy, played by Shia LeBeouf. They tried to make him a tough kid, but I'm afraid that no matter how many lousy action films they put him in he'll always be Stanley Yelnats for me. I was sorry they gave him a couple of vulgar exclamations.

My favorite line, delivered as only Harrison Ford could:
"So what does that make you? A triple agent?"

Better than Temple of Doom, not as good as Last Crusade, still a worthy addition to the series. However, when the writers have to resort to space-aliens and psychic Russian lady spies, it is probably time for Indy to hang up his hat.

Putting It All Together

At last the time had come. All the pieces were shaped, fitted, and stained. The harp was ready to be assembled!


I always put this inscription on the back of the soundboard of my harps.




I had already attached the top and bottom of the box to the arch and pillar using wood screws and wood glue. Next I needed to install the wood screws to hold the box together, two on each corner. Because I was working so close to the edges of the boards it was very important to countersink the screws so the boards would not crack.

This red metal brace is to keep the top of the arch from twisting due to the torque from the strings. I'll cover it with a stained wood piece to make it look nice once everything else is assembled.





Once the wood screws are all in place I take them out on one side so I can glue in the soundboard and the back of the box. I'm using 2 ton epoxy with a 30 minute working time for the soundboard. There is between 500 and 1000 pounds of pressure on the soundboard once all the strings are tuned up tight, so 2 ton epoxy ought to do the trick.

First I put wood glue in the grooves for the box back and slide it in place. Then I pull out the soundboard and spread the epoxy in those grooves before sliding it back into place. Last of all I prepare the remaining side of the box with a new batch of epoxy. After putting the side of the box on, I screw the wood screws in. All done!

After the epoxy has cured I cover the metal brace at the top, then add the foot pieces at the bottom of the pillar. The foot pieces are important to help the harp stand upright and to keep the base of the pillar from twisting. I added a decorative wood piece on the arch at the top of the box, just because I felt like it. Those other pieces of light-colored wood are not just for decoration. The long ones keep the pillar from bending under the tension of the strings.





Notice that the bottom of the string rib is braced by the inside edge of the pillar. This is to keep the strings from ripping the soundboard out of the base of the box.

In the Ploo!

When my two-year old came in from playing out back, I asked him where his glasses were. He had them on when he went out, but not anymore.

"In the ploo!" he said.

"In the pool?"

"Yeah."

"I wouldn't put it past him," my husband said.

One of my two-year-old's favorite pastimes is standing at the pool fence and throwing rocks, toys, sidewalk chalk, and whatever he can find into the pool. We got the gate key and went out to look. Sure enough, after my husband had fished up several rocks, he netted the glasses. They were in the ploo. Our two-year-old has been banned from playing on the back patio until further notice.

I wasn't sad about him being cross-eyed and needing glasses until I saw a video of him taken about a year ago. There he was, cute baby face, two blue eyes staring at the camera, both straight on. It made my heart ache. He looks so different now. I find that when I look at him I'm drawn to focus on the eye that is not looking at me, and it gives me the impression that I don't really have his attention. I do hope he grows out of it.

Fitting the Soundboard

After staining the sides of the box and the pillar and arch I was ready to fit the soundboard. I cut it a little large so that I could sand it to a perfect match. Once the sides of the box fit snug with the soundboard in place, I disassembled the harp again so that I could put the string rib on.

Many harps these days don't have a top string rib. The top string rib is to protect the soundboard from the strings. Metal grommets can serve the same purpose. The bottom string rib is more important, giving a strong anchor for the strings. For me, the grommets are too much extra work, and I like the look of a top string rib much better.


I thought those old encyclopedias would be good for something someday. Once the glue is dry, I can drill the holes for the strings. Then it will be time to assemble the harp!

Rebecca's Reviews: Fablehaven 3: The Grip of the Shadow Plague

No author I know can top Brandon Mull for sheer imaginative power.

Kendra and Seth Sorenson are the grandchildren of the caretakers of Fablehaven preserve, one of the few places left on earth where magical creatures can live on in an increasingly skeptical world. The trouble is, not all magical creatures are nice. In fact, some of them are downright evil. All the worst ones have been locked away in a magical prison, and if they ever get out, the world as we know it is basically over.

Mull creates a world where the stakes are high, danger is real, and almost everyone is under suspicion. His book has an endless parade of fascinating magical creatures, each with their own habits and personality. Fablehaven 3 contains Mull's best paced plot so far, with lots of adventures, an intense action climax, and an ending that leaves the reader eager for the next book.

Mull introduces some great new characters in this book, and only kills off about half of them. He's still having trouble with Grandma Sorensen, who had more personality during the time she had been turned into a chicken, but his tween-aged characters live and breathe as always. Seth is still my favorite, and I'm glad to see him begin to discover more of his abilities in this book.

So go out and buy your own copy. You certainly can't borrow mine. My husband is going to start reading it to our children tonight, and we just can't wait!

Rebecca's Reviews: Prince Caspian

It all began so well.

The film opens by taking advantage of all the natural drama of cut-throat politics. Young Prince Caspian has to flee for his life because his evil usurping uncle's wife has just given birth to a son and potential heir. Fortunately for Caspian, he has a secret passage at the back of his wardrobe, and thus avoids being made into a pincushion in his sleep. Caspian's kindly old tutor sends him into the woods, where he encounters the Narnians: talking animals and assorted creatures from Greek Mythology who have been in hiding since Caspian's ancestors took over.

Meanwhile, Peter, Susan, Edmund, and Lucy have been through a miserable year of trying to adjust to life in dreary old 1940's England after having been kings and queens of Narnia. Just as they're about to take the train to boarding school, the train station blows away and leaves them standing on a beach. Can you get any more wishful thinking than that? The kids immediately guess they're back in Narnia, I mean, where else could they be? What they don't know is that it has been over 1000 years since their last visit, and this time they have to help Caspian reclaim his rightful throne.

The first half of the film enchanted me. Everything worked, even Edmund's electric torch. Storming the evil uncle's castle was an unexpected twist that had not been in the book, and it turned out to be one of my favorite sequences of the film. The spell remained unbroken until at one point King Peter and Prince Caspian start blaming each other and arguing in front of everyone like a couple of idiot teenage boys. I know they are teenage boys, but Peter has been a king and Caspian has been trained to be one, and rule numero uno is: never argue in front of the troops! It was so-o-o-o unprofessional.

After that point, the film got a little silly. Sure, the epic battle scenes were great to watch, but if Aslan could have shown up and saved the day sooner, why didn't he? They tossed out a few excuses as to why he waited until the last minute, but I was not convinced.

Still, I couldn't help feeling an ache of loss when Peter, Susan, Edmund, and Lucy end up back at the dreary old train station again. Everything in Narnia is beautiful, the landscape, the architecture, the CG creatures, the costuming, and even Caspian's embroidered pajamas, which I think he wore for most of the film. No time to pack when you're running for your life, I guess.

Lots of people die violent deaths in this film. I agree with those who said it should have had a PG-13 rating. I don't know if that would have stopped anyone from taking their little kids to it without seeing it themselves, but it might have made the director take the film back and cut out some of the more disturbing footage to earn it a well deserved PG.
