A Different Sort of Boating

A couple weeks ago Lora and I headed west to do a bit of paddleboarding on the lower Colorado. Oddly, we could not cajole any of our friends into joining us. This might be termed foreshadowing.

For night one we chose a camp at the foot of Davis Dam, a ways upstream of Bullhead City. We set up camp and launched mid-afternoon with no particular destination in mind, with a list of taxis numbers and a cell phone in our bag. Interesting terrain.


We were still getting used to this stand-up thing, as you can see by my stance. I am trying here to eddy out behind a flooded palm tree, to no avail. The water was pretty high that day.


The scenery was not familiar to us upper Colorado canyon boaters. This is beautiful Laughlin, Nevada. Most of the turbulence came from water taxis ferrying victims from Bullhead City over to the casinos in Laughlin to have their pockets drained. 


Of our three tentative takeouts, we made it eleven miles to the furthest one and pulled out on the south side of Bullhead City at Lazy Harry's Bar & Grill. 


Lora grabbed a taxi to retrieve the car while I took in the local scenery. 


We got up early and drove downriver to Topock where Interstate 40 crosses the Colorado. This is the start of Topock Gorge, a scenic wildlife refuge with no settlements along the way. We figured we'd paid our dues to civilization the previous day and were looking forward to a bit more of a wilderness paddle. More foreshadowing here.


At Topock Marina we met up with Henry, who I had found online earlier, and shuttled my car down to Castle Rock, the first takeout below Topock--still well above Lake Havasu City. We finally launched around ten for the fifteen mile paddle. There was a slight upstream breeze but nothing to worry about. 




The gorge really is pretty and the central part of it has a no-wake zone to slow down the vacationing motorboaters. Still a pretty cool trip. But as we left the gorge three things happened. The current died out. The upstream wind picked up. And a swarm of dick boats roared upstream to share their cacophony and wakes with us.

Turns out, upon subsequent conversations with friends, that Lora and I might have been the only two people on earth that were unaware of a few phenomena.
1) Working people and students often celebrate a thing called "Spring Break" about this time of year.
2) The favorite way for many to celebrate Spring Break is to go to Lake Havasu and rent dick boats.
3) Dick boats can be defined as unconscionably overpowered, hideously consumptive, dangerously fast, ear-bleedingly loud boats, driven in a dickish manner, by dicks.

My friend Dan later pointed out that it was our own damned fault and what were we, nuts? But we didn't know. So we paddled on in dying current and increasing upstream winds into the heart of the annual dick boat storm. The wakes were bad enough, but the deafening blasts of unmuffled (or perhaps amplified?) five-hundred horse engines shrieking past was beyond painful. We stopped for lunch and pondered our predicament. Only one way out. Keep paddling.


Late that afternoon we finally found the slot in the reeds leading into Castle Rock Bay and our ordeal came to an end.


We were exhausted but we'd learned a few things. We got way more stable on the boards due to the incessant and erratic wakes. We got really good at paddling hard and long on both sides. And we learned about dick boats. But I guess we still needed to learn a bit more.

Our destination the next morning was a folk festival near Phoenix, so I had researched online and found a state park along the way, in the mountainous terrain down below Parker Dam, on a bend in the river. It looked lovely and we reserved the site that appeared to be closest to the river. Site R. No one else had reserved any of the spots anywhere near, so we thought we might get a little seclusion. More foreshadowing.


Turns out the campsites are a series of concrete bunkers that share cinderblock walls with the site next to them. We were too tired to do much but laugh, so we settled into Bunker R and went down to the shore for a beer. Ahhhh, but it turns out Buckskin Mountain State Park is on a dick boat speedway.


Lora began to lose her sense of humor. I went out for one last paddle to get the kinks out before calling it an early night in the back of the van.


We had a few strong drinks to help us sleep, pulled the curtains, and laid down. We hoped the dick boats would go to sleep after dark, but that's not what they do. They drink. And take off any remaining mufflers. And drink some more. And go boating. As fast as they can possibly go. Back. And forth. And back. And forth. And at sixty miles and hour it doesn't take very long to go back. Or forth. And out on this bend of the river the surrounding cliffs work nicely to amplify and reverberate the roar of the engine screaming by.

Well, somewhere in the middle of that long, wretched night one of the dick boats went ahead and drove full speed straight into the cliff across from us, exploded, and commenced to sink. By the time we were awake and alert enough to comprehend what the ruckus was, 911 was on the way, the fire trucks were all around us, and the life-flight helicopter was landing pretty much on top of us. That went on for a few hours before subsiding to the baseline roar. Here's what remained the following morning.


Here is the lay of the land from a peak we hiked to after our morning coffee.


Well. Yeah. It was an adventure. I can't say I recommend paddleboarding the lower Colorado, at least not that time of year. But we did learn a few things, got a lot better at paddleboarding, and got a few more stories. And the Glendale Folk & Heritage Festival was lovely.

Skookum handles

Sam Johnson, my bronze casting instructor, called a few of my oversized projects "skookum." I had to look it up. It is a Chinook word meaning many things, among them: good, tough, powerful, beefy, tough, brave, durable. Not at all dainty. I decided it was a compliment, and Sam did add that he liked things of the skookum sort.

So I made some skookum handles for my skookum boatshop doors. I made the pattern from some giant rope that I soaked in epoxy, bent to shape for hardening, then sanded the rough prickles off of. I glued on a couple round, tapered wooden base plates to make them easy to install on the doors and solid once in place. Then I had to convince my sand mold to part around such an irregular shape without exploding when I removed the pattern. This part went smoother than I had any reason to hope for, but still a bit jagged.


But before I cast them I had to chunk up a few silicon bronze ingots into sizes small enough to fit in my crucible. At school we used a Milwaukee handheld bandsaw. It took a lot of time and we went through a lot of blades. This time I tried using a special nonferrous cutting blade in my semiretired chop saw. A terrifying proposition requiring full body condomization.


Criminy, what a racket that made. But it went through them like butter. Or sliced bread.


Then we fired up the foundry to about two thousand degrees, stuffed the crucible full of bronze, waited until it was yellow-hot, and started pouring.


You can save a little clean-up time by pulling off some of the extra bronze before it hardens.


While I was dorking around with my skookum handle molding, Lora cranked out the molds for about six dozen more little star washers for my upcoming gunwale project. The washers came out great. Since I am a bit short on casting sand, I'm dumping the uncharred portion of the used mold sand directly back into the sifter so we can wheel it indoors to build the next mold.


At first I feared my handles would require more bronze than my crucible would hold, but I got lucky. The pour went well. Here is the first handle coming out of the sand. My mold was not as perfect as I hoped, so I was still worried that it might not really work. Dubious would be a good adjective here.


Into the quenching bucket.



Omigod. It actually worked.


A lot more bronze goes into a pour than actually gets used in the object: gates and runners, sprue and pouring cup. These all get cast in bronze too, and must be cut off and chopped into small enough pieces to return to the crucible for the next project. Here I am using my cool new Dewalt cordless bandsaw, which proved to be just the ticket for this process.


With two skookum handles and a half-gross of washers all cast, we shut down the foundry and let the crucible cool until next time.


After a half-day of grinding off the parting lines and polishing on the buffing wheels, the beasts looked pretty good. I drilled and tapped half-inch holes in them and screwed in some threaded rod. Then I drilled some countersunk holes into my giant doors and bolted them on. I love 'em. And they're hell for skookum.

Twinkle twinkle

My preferred method of fastening gunwales to a boat, for a few years now, is using a machine crew with a finishing washer on the inside of the boat, into a sex nut (a sort of sunken barrel bolt kind of thing). It's clean and pretty, quick and easy, and it is a cinch to take off the gunwales when somebody wrecks the boat. Here's an example of how they look, on last year's Rio Rojo. Machine screws and finish washers on the inside (orange arrows) and sex nuts on the outside (green arrows). 


Here are currently available finish washers in silicon bronze and brass.


But something has been bugging me about the finish washers. They are made of stamped sheet metal, so the edges dig into the gunwale when they are sufficiently tightened. It cuts the grain of the wood a bit sometimes. And I have looked the world over (well, on the internet) and have yet to find any solid finish washers. They just don't make 'em.


So the solution, I decided, was to make my own. And why make them round when I could have more fun? Step one was to carve a little star out of wood, with a countersunk hole in the middle, and glue a wee nail into it.


Step two was to make eleven more.


Step three: trim the little nails and glue them into a central stick.


There. A stick with twelve stars.


Sand it oh-so-smooth, shellac it a few coats, and get out the foundry materials. I was too busy to photograph pounding my star-stick into a sand mold, but here is the aftermath.


It's been eight months since I took my bronze-casting course and rushed home to build my own foundry. I fired it up at that time and it worked. Now it's time to see if I remembered all the things one has to do to make it work. I guess it's time to wait for the bronze to melt. 
   Check out the cool Nomex suit my friend Day gave me. It might not stop flying 2000° bronze, but at least it won't burst into flame.

 

Wait 'til the bronze has melted into a nice bright yellow pool, clean off the slag, and pour it into the mold.


So far, so good. But did I make the mold right?


It bursts into flame when I open it up. This is actually a good sign. It means there is a bunch of hot bronze in there where it is supposed to be.


To the quenching bucket.


By god it worked perfect.


A bit of cutting, grinding, and polishing and voila. Aren't they adorable?


They look kinda cool in a gunwale scrap. Note the bad case of foundryman's hand.


Only four more pours and I'll have sixty of them, enough for the rehabilitation of my forty-three-year-old dory Cataract. Tuesday afternoon is the plan. Come by and play if you like. Leather shoes, nonflammable clothes, safety glasses. It's the law.

Really Rapid Roberts

We finished up the second of the twin Rapid Roberts on our next day of work. Alan, Lora and I did the gunwale bolts first thing in the morning. Then I worked on trim pieces while Alan routed sanded and oiled her down. And out the door she goes, down the street to Alan's house for paint and interior fittings.






Hating to see a good shop go idle, we immediately began laying up Roy's side panels for his new Betty Boop clone, to be named in honor of the first dory on the Colorado back in 1889, a pine ocean dory named Brown Betty. We are hoping the new Brown Betty fares better than the original, which sank in its very first rapid upon entering Cataract Canyon. The rapid bears her name.


We pulled the lines off the original Betty Boop on Valentines Day 2012, just after I had finished a full restoration of her rotting 1967 hull.


Then a year ago, Jim Mackenzie and I lofted the lines and built the hull for his replica, Olo.  She came out beautifully.



But when Jim and I were laying out the side panels, we struggled to make the panel corner angles of Olo match those on the Betty Boop until smoke started coming out our ears. We got very close, but in the end, just gave it our best shot. This time we encountered the same problem and may have solved it by adding 1-3/8 inches to the sheer line length and shifting the position of the rib stations a bit. I doubt anyone will be able to tell the difference between the hull shapes of Olo and Brown Betty, but at least Roy and I will know we got the damned angles to agree this time.

In an unusual fit of caution, we clamped the entire boat together before drilling our screw holes to make sure our brainstorm was not going to backfire. It didn't so we went ahead and screwed her together.



Amy and Roy: proud parents of their second wooden boat. It is so fun to infect others with such impractical ideas.
