Valve-grinding: a team effort

This week, I finished cleaning all the valves for the Thea Foss. Engineer Ron ground the valves and observed that “the first one is fun and the rest of the 24 are boring,” which I definitely agree with. Then Vince came out of retirement and over the mountains to grind the seats, and we had a nice team to get the job done efficiently.

A visit to the Cape Cross

Later this week, I visited the crew of the Enterprise-powered fish tender Cape Cross. The engine’s running well and best of all, the boat is gainfully employed.

Dry-suit repairs

After last week‘s brush with carotid sinus reflux, diver Duane helped me replace the neck seal in my dry suit. Apparently adding a latex neck seal to a neoprene suit is pretty common, and it’s an easy process. First, I coated the sealing area with AquaSeal and let it cure, then I put another coat on to adhere the latex. Then I trimmed it and put one more bead of AquaSeal on edges, and the suit was ready to go.

Giving the CWB a lift

On Saturday, I worked with Sterling Marine Services Llc to level out some of the floating docks at the Center for Wooden Boats by installing some new barrels. Once we got we got a system down, it went really fast. Sterling Marine Services Llc has posted more about it in their brand-new blog here.

Repairs and updates on the Island Champion

I visited the Island Champion this week to isolate the overboard through-hull fixture from the engine. This is an area of excessive stray voltage, which induces electrolysis in the surrounding planks and makes them rot out a lot faster – according to our resources, it’s like nail sickness from increased alkalinity.

I installed piece of hose to separate the engine from the through-hull fitting, which disrupts (in theory) the electrical current running between them:

This should hopefully stop the electrolysis and save the hull timber a little longer.

Also, boat buyers take note: the Island Champion is not for sale anymore.

To bond or not to bond

This brings up the age old-argument: “to bond or not to bond.”

To bond, or not to bond: that is the question:
Whether less noble metals should suffer
The slings and arrows of outrageous corrosion,
Or to take arms against a sea of troubles,
And insulate them. To dielectric: to isolate;
No more; and by isolate to say we end
The corrosion and the thousand natural shocks
That hulls are heir to, ’tis a consummation
Devoutly to be wish’d. To dielectric, to isolate;

On the subject of galvanic corrosion: the way I read it, impressed current is best but anodes are easier and more common. If using anodes, quantity and placement are very important to get right and bonding or isolating is addressed on a case-by-case basis.

Some fittings below the waterline, if isolated, can take a long time to degrade, while others will need to be wired to the anode using a resistance-free electrical circuit with heavy-gauge wire, good connections, and keeping it out of the bilge water. When working with mili-volts, a loose connection is no connection: the mili-volt will not jump a gap. I think it is this sloppy wiring that causes bias in our maritime tradesmen.

More important than the bonding and anoding, boats and equipment should be inspected and repaired regularly – and repairs should be made before small problems are catastrophic. It pains me to hear folks argue about bonding while the boat is sinking. While limiting galvanic activity is important – keep it in perspective!

Update on the Maris Pearl

Meanwhile on the Maris Pearl, we’re down to just looking for the shaft that attaches to the piston in the reversing mechanism and the camshaft gear.

Who’s got one? Any drawings? Anything? Help?

Work begins on the Arthur Foss

The Northwest Seaport started their “Stop the Leaks” project on the Arthur Foss; it sounds like the first step was to take off the big rubber fender on the bow. They took a lot of pictures of it – and better yet, wrote a blog about it! Check it out here!

More work on the Maris Pearl

I’m still working on the Maris Pearl‘s reversing mechanism, trying to track down parts for it. I’ve been working with suppliers and calling collectors and engine owners I know who have spares. The Westinghouse controls rarely need attention, so there’s not a lot of information available on these units. It’s taken some extra time to search it out.

Winter Work on the Thea Foss

The Thea Foss‘s twin Atlas-Imperials are getting some attention this winter. The boat’s engineer worked with Dan to remove all the valves, start valves, and injectors out of both engines, then I spent a lot of time this week disassembling and cleaning everything.

As you remember, this process involves disassembling them each, putting them in a solvent bath, flushing the water jackets, sand blasting and another solvent bath, flapper the guide, and wire-wheel the stems.

2010 M4 Party

The big annual art and music event that OTM helps sponsor now has a not-for-profit fiscal sponsor, so make your donations out to Shunpike, with M4 mentioned as the program.

This year’s show will be the 10th annual, on May 1st. The steering committee is planning furiously, and it’ll be even bigger and better than last year (always our goal).

Working on the bow thruster

We got the new parts and tools to fix my good customer’s bow thruster, but still got caught inadequately prepared. I had to run out in the middle of the job to get more parts.

I also had a problem with my dry suit: the neck seal was too tight. Apparently, this can cause Carotid Sinus Reflex, when your neck seal presses against the carotid artery and makes your brain think your blood pressure is too high and lower your pulse rate to compensate.

The symptoms can include nervousness and a shortness of breath, which at the time I attributed to being out of practice from not diving enough. While it is true I am a little out of practice, the nervousness and shortness of breath were actually due to the neck seal. I’ll replace this before next week, in time to dive next Saturday at the CWB.

Despite all this, we still got the bow thruster fixed right up.

Boats for sale

The Pacific Sunrise is for sale. It’s a sweet boat with an Atlas-Imperial 6HM1125 diesel, and is going for $75,000.

The Island Champion is also for sale. She’s a great boat with a Fairbanks-Morse 35F14 diesel.

New corporate vehicle

OTM Inc got a new truck this week after the old Ford Courier exploded. The new OTM-mobile, a Chevy S-10, has more power and big wheels to fix your heavy-duty faster. It also has working lights, windshield wipers, a heater, and tire tread, all unlike the Courier.

More work on the Maris Pearl

Spent more time cleaning and painting cleaning and painting on the Maris Pearl.

Engineer on the Thea for a night

Every year the Thea Foss‘s crew gets a night out on the lake as guests on their own boat. They put together a relief crew for this night, which provides the dual benefit of ensuring that the Thea has a relief crew that’s “Always Ready.”

It was a great night out on the lake and I can never get enough of the twin Atlas-Imperials – even with their 200 oil points each.

Jensen Motor Boat Party

Jensen Motor Boat Company is an institution of great carpentry and ridiculous sea stories. Once again, I’m very pleased to be invited to the holiday party where there is no end to the wine or food.

I got there a little late but made it in plenty of time for a great party. Thanks, guys!

Museums are not a public service

I know they look like libraries, but most museums are private institutions. They receive tax benefits because they provide community benefits, but this does not mean that they must provide specific services or that individuals are entitled to make demands of a museum. This seems to be a frequent cause of misunderstanding, especially in the old boat community, and I believe it’s important to make some distinctions and clear up those misunderstandings.

Museums benefit communities in many specific ways, one example being by providing educational opportunities, and this grants them tax benefits to support the services they provide. Individuals supposedly benefit the community by getting married and having kids and so they receive tax benefits to support that service. Now, while both institutions are exempt from taxes, this money is essentially being taken from those of us who are not entitled to tax breaks and use the community services. It’s therefore just as unreasonable to demand that a museum “save” your crappy old boat as it is for me to demand that your kid mow my lawn.

2008 Week 39 in Review

Back to business-as-usual

This week, I’ve gotten back in the shop. I worked on cleaning up an engine control station that I picked up recently. It’s a neat find, perfect for a direct-reversing twin-screw boat. After I finish cleaning it up, I’ll post pictures and put it up on eBay – hopefully by next week.

I also worked on the Duwamish a bit – I checked the cylinder height with a standard gasket and it is too low. The piston goes up past the liner slightly, so next week I’ll put a thicker gasket under it. I’ve got to get this project wrapped up soon, though.

I also cleaned up the shop a bit, and caught up on news from the shop partners. Brian and his shipwright partners are all settled in, John moved out, Grant is moving into John’s old space, and we’re going to be looking for another shop partner soon. My space is right in the center of the shop, so I spend quite a lot of time BSing with everyone who works there. I call this an investment, rather than a waste of time. We may not talk about anything important, but this business requires a lot of social interaction. When I have a question, I can get answer much faster if I am all caught up on the news.

I also worked on taxes and other “business” things. Lame. Stuff like this takes the fun out of running a small business.

Sakarissa moves

We received the following email from Jerry, who works with the Amphibious Forces Memorial Museum, which is thinking about buying the Sakarissa (a WWII “Yard Tug,” sister ship to the Maris Pearl and the Red Cloud):

YTB-269 was built in Tacoma and commissioned 12 April 1944. She served in the Pacific assisting in the operation and transport of ABSD-1 (advance base sectional dry-dock). These large docks were capable of lifting a battleship and were used to repair ships in Eniwetok and Guam during and after the war. The ship returned home to San Francisco on August 22, 1946. She was used for assist duty for the USN until 1974 and was then transferred to MARAD at Suisan Bay tending to the needs of the mothball fleet there. The Sakarissa will join the growing fleet of historic vessels in the Portland/Vancouver WA area. She will become an educational resource attesting to the era when maritime services played a major role in the economy of the Northwest and of the labor that built ships and those few still working to preserve that history.

Jerry also sent a bunch of pictures of the tug, including this engine room shot:

Enterprise DMQ-8 diesel engine powering the ex-Navy tug SAKARISSA

This is the same engine built on the same contract as the Red Cloud and the Maris Pearl, but unlike those two it doesn’t have the clear camshaft view ports on the starboard side. Interesting.

Thanks for the update and the photos, Jerry – I hope that I can make it to the Sakarissa when I’m down in Oregon next month.

Footage from the Quail

Dirk and his friend were treated to a demonstration of the tugboat Quail‘s Atlas-Imperial diesel. Here’s a video of starting her up:

Thanks, Dirk!

What is “original?”

When you’re taking care of engines for which spare parts haven’t been manufactured for 50 years, things tend to get changed around a lot. While I try to stick to the original manufactures’ parts and process, I have had to stray sometimes. If I can’t keep the engine “original”, then the next most important thing is to document the changes that do happen. I’ve been keeping track of the changes I’ve made, but I need to start making better records of the process. I’m going to start a list of variances to the OEM (Original Engine Manufacturer) designs here and on the website. Over time, I hope to document all of the changes I’ve made – and all of the changes that other people have made and told me about.

Here’s a few to start off with:

On the Arthur Foss‘s Washington:

  • the fuel pressure regulator is an Atlas-Imperial fuel pressure regulator
  • numbers two through six cylinder heads are a newer style with two studs and a collar to hold the valve cages, instead of one big castellated nut around the cage
  • the new set of tappet guides have a zerk fitting or 1/8-inch pipe tapped hole in each

On the Catalyst‘s Washington:

  • the injector tips, while Washington-style on the outside, are Atlas-Imperial-style on the inside
  • the fuel pressure regulator has an atlas imperial seat and stem – inferior to the reversible Washington design
  • the new valves are one-piece (this is forgivable)
  • the valve cages have new noses and are not one piece any more
  • the guides are off the shelf (from MAN or something)
  • the rod bearing nuts are nylock and not “large profile”
  • the clutch guide pins are two piece
  • the pneumatic shifting has been replaced with hydraulic

On the Westward‘s Atlas-Imperial:

  • no Manzell

On the Thea Foss‘s Atlas-Imperials:

  • much of the engine room controls have been replaced or altered to allow better remote operation

On the Briana Marin‘s Enterprise:

  • the thrust bearing and carrying portion of the bed plate has been removed to make room for the gear

That’s it for now. Mechanics, owners, enthusiasts: do you know of any other changes to any other heavy-duty boat? Comment here and we’ll start putting together this record.

Autumn Programs at Northwest Seaport

Old Tacoma Marine Inc has a very good relationship with the Northwest Seaport and I try to help them out when I can. I’m of course most interested in the programs involving the Arthur Foss. I teach all the engine classes held aboard, and last year I not only directed (instigated) the Classic Workboat Show, but I was also the largest sponsor of time and money. Autumn is planning season for Northwest Seaport, so I’ve gotten more involved again by helping them plan next year’s programming and raise funds to make it all happen.

As a start, I went the Lake Union Park Working Group meeting, held every other Friday. All the groups with a stake at South Lake Union send representatives to discuss everything going on, from individual projects to giant joint programs. A major item on the agenda this week was planning joint programs for 2009, but we ended up pushing that back to the next meeting to give all the groups a little more time to recover from the summer. I’m going to meet with Northwest Seaport before that next meeting to commit to expanding the programming schedule just a little more, like we’ve done for the past few years.

I have a few programs that I try to put on every year with the Seaport and the Center for Wooden Boats: Engineer for a Day, Diesel Engine Theory, and the new Tugboat night. These are each engine-centric, mostly on the Arthur, but Engineer for a Day uses all four boats on the wharf (I wrote about it way way back in February). The biggest (and most expensive) single class is Diesel Engine Theory, which is our take-it-apart-and-fix-it class that we’re using to restore the Arthur‘s big Washington:

Diesel Engine Theory 2006 aboard the tugboat Arthur Foss

We’re planning out next year’s programs and finishing this year’s, and finding (as usual) that the main need for each class is participants and funding. For this year’s Diesel Engine Theory class (the only remaining 2008 program), we’ve already got two or three people signed up, and Northwest Seaport is already a third of the way towards raising the total cost of the program (thanks to a 4Culture Special Projects grant), but we really need to fill the class and get the other two-thirds of the money in hand before we start this year’s work.

Northwest Seaport’s staff and board are very busy, so I usually take on a lot of the behind-the-scenes program management. This includes advertising the class and fundraising, on top of the mechanic stuff I need to do to get ready (we really need to order rings soon). This work is essential, since without the organizing, advertising, fundraising, and paper trail, we are spinning our wheels as opposed to building something solid and sustainable that transcends the boat itself.

This gets back to one of my major philosophies. To lift up a boat (or a maritime organization) you need something bigger than that boat (or maritime organization). I think that the best “something bigger” is education. Engine room education is important (the YMTA can tell you why better than I can) and the Arthur Foss just happens to be the best platform for this type of training. She’s a really neat boat, owned by a museum that’s dedicated to keeping her around to teach the public about boats, and she’s moored in the middle of Seattle. The classes and programs we run aboard her for the benefit of the general public can lift the Arthur Foss up and make something more of her than just an old boat.

Of course, last year a program literally lifted the Arthur Foss right out of the water:

the tugboat Arthur Foss in dry-dock, October 2007

That was a great feeling.

Getting back to the upcoming Diesel Engine Theory course, we need behind-the-scenes funding to get it off the ground. If you can help out, contact me now.

The wish list as it stands for the upcoming Arthur Foss programming includes:

  • cash
  • diesel fuel and lubricating oils
  • program participants
  • time on a dry dock
  • (1) 18-to-one torque multiplier
  • volunteers to do behind the scenes work (advertising, fundraising, setup, etc) – sign up for one or more positions now!
