2010 Week 22 in Review

Washington injectors, finished!

This week, OTM Inc finally finished rebuilding the injectors for the Timber Heritage Association‘s Estep yarder. Two of the three operate well, but the third has a smashed tip that I hope they’ll order replaced soon. In the meantime, all three injectors look great!

Enterprise injectors, begun

Martin from Hatch & Kirk is working on a new injector nozzle for a G Enterprise, so we dug up one of our spare heads to check the spray angle and tip depth into the cylinder.

Martin and I also disassembled four injectors from the Maris Pearl, then inspected, reassembled, and tested each. It turns out that even though they were leaking, three of them were within specs. The fourth was ruined and it’s a good thing we changed it out: the pintle had been badly scored, possibly from dirt. We’ll discard the worn parts and save the rest for spares.

Lightship 83 Request for Proposals

In the office, we’ve made a bunch of revisions to the draft Request for Proposals for the Lightship project. Hopefully, it will go out on the street soon.

Work on the Arthur Foss

OTM Inc is assisting Ocean Bay Marine in buttoning up the Arthur Foss. We’ve decided to pull the tarp and seal up the wheel house as best we can with the funding available. This will bring the work on the wheel house to a good stopping point, but not a finishing point. We hope to tackle it again next summer with renewed funding dedicated to the project.

Work on the Maris Pearl

Meanwhile, back on the Pearl, we’re looking for water leaks in the engine, as it seems a few cylinders are leaking water into the base – not enough to turn the oil milky or anything, but still a few drips when it’s cold (none when it’s warm). It looks like we will be changing out some cylinder heads soon.

California Planning

In future news, OTM Inc is planning a trip south to see the Portola and the Sobre las Olas. We got a request to perform an engine survey for the Portola, in addition to doing a few repairs and acting as engineer for a few trips. A potential buyer who obviously has really good taste fell in love with the boat and wants some technical advice and assistance. I’m looking forward to seeing her out cruising again, so I hope the sale works out.

While in California, I’ll do some more work on the Sobre, another beautiful heavy-duty yacht. This ought to be a fun trip. Details soon.

OTM Inc, the educators

For years, we at OTM Inc have been using heavy-duty diesels as training aids to people new to diesels. Our collaborative high school classes have won high praise, and now we’re working with The Anchor Program to design more educational opportunities for those interested in engines and boats. More on this later.

Here’s this week’s cruising schedule aboard Catalyst, from Juneau to Petersburg:

Sunday, August 17 – Juneau to Limestone Inlet: kayak paddle in river, salmon in river and along shore (rainy)
Monday, August 18 – Limestone Inlet to Ford’s Terror: meet Ranger Tim, Kayak Ford’s Terror, brown bear in creek (foggy)
Tuesday, August 19 – Ford’s Terror to Wood Spit: hike Ford’s Terror highlands, Dawes Glacier, seals, whales (hazy sun)
Wednesday, August 20 Wood Spit to Donkey Bay: great whale show, paddle Donkey Bay, 1000′s of salmon in creek (sunny)
Thursday, August 21 – Donkey Bay to Brothers Islands: forest walk, kayak paddle w/ eagle, sea lions & whales, meet Westward & Fred

Saturday, August 23 – Scenery Cove to Petersburg: last run, pack and prepare to return to what passes for civilization (but isn’t)

Here’s the crew:

And here’re the passengers:

This week, I saw Ranger Tim. I first met him in 2000 while on the Westward. We picked him up on the way to Fords Terror and chatted for a few hours. I love seeing all the Southeast Alaska people I worked with nine years ago, especially since they’ve now taken on a cartoonish personality in my mind.

I paddled up Fords Terror again (the glacier was great), picked up more crabs, and met up with whale researcher Fred Sharpe. I also took some video of the Catalyst, which I’ll post once I figure out how to get it out of my camera. For now, here’s a picture of Bairds Glacier:

Westward Rendezvous

We rafted up with the Westward on Thursday, on its return from a 20,483-mile journey around the Pacific:

classic

We’ve been getting updates on their progress for the past year or two that they’ve been out, so it was great to see them all again. They anchored at the Brothers Islands to rendezvous with us for a potluck dinner. The Westward looks great after all those miles, and owner Hugh was still the life of the party. I’ll write a much more detailed account of the meet-up once I have a few minutes to myself, since it was a highlight of the trip. Stay tuned!

Business as usual
I removed the exhaust valve from cylinders one and two, just to continue cleaning them up. Of course they were bad, so I put in spares. I also noticed the oil psi going down over time, and it’s time for an oil change if we continue changing based on time and not on sample results. The oil smells a little diesel-y and with all the overloading fuel, it could be soaking down past the piston or an external leak, and making its way into the crankpit. I will change it in Petersburg for sure and take a sample for the lab.

A good home for the Ready?

Word is spreading about the neat old tug Ready, which is for sale only to a good owner. The boat needs to be hauled out for some hull repair, and the new owner needs the guts to maintain, insure and operate a tug with a direct reversing Atlas-Imperial diesel.

Problems on the Velero IV?

I’ve heard that the Velero is having some timing problems these days. She’s a fish packer and research boat that’s powered by the biggest Atlas diesel still running. Owner Irv does a great job not only keeping the boat looking good, but also finding jobs to keep her employed full time. As I always say, the best way to maintain and preserve an engine is to give it some real work to do.

The Velero‘s engine was extensively modified in the 1950s with a second camshaft, Bosch fuel pumps, and injectors to increase its horsepower and efficiency. The work was done by the same guy who added the Bosch fuel pump to the Portola down in Seal Beach. The new port-side camshaft has something like a dog clutch with a precise gap, so when going into reverse, the second camshaft’s timing changes. The bolts holding the spring-loaded detent for the “gaped dog clutch” and the timing sprocket both broke. Fatigue, maybe, but the system is a one-of-a-kind. Irv may not be able to do much more than replace them and watch them more closely. I really wish I could do more than troubleshoot over the phone right now, but hopefully I’ll be there during winter maintenance for a closer look.

Lost Heavy-duties

Dirk sent us some pictures from his own collection of the Broughton Straits, a 100-foot tug that he piloted to Port Townsend in 1978:

Tug

Dirk recalled that the Broughton Straits was powered by a six- or eight-cylinder Washington diesel that made about 300 horsepower, and he remembered that “it had a large turbo but I was told the turbo had be ‘deactivated’ and wasn’t spinning any more.” He also remembered that it had a Fairbanks-Morse gen set. He sent several pictures that he’d taken in 1978, including this one:

We’ve gone through the Washington Iron Works records that we have, and found the engine card. Engine 7624 was ordered on October 17th, 1947 by the Straits Towing & Salvage Co of Vancouver, BC through the Vancouver Machinery Depot.

According to the card, the engine was a model 6-160 (same as the Donald R) with six cylinders at 12 ¾” by 16″. These models got between 375 and 400 horsepower at 327 to 360 rpm. The Broughton Straits‘ record shows it rated at 375 horsepower, with direct reverse and no clutch.

The card also shows the tug’s original name as Stan Point, but as with many of the records, that name was crossed out and the new name written beside. The folks at Washington Iron Works made a lot of notes on this record card as they did maintenance and repairs through the years. We’ve uploaded a copy of it here, and the reverse side with some testing notations here. Dan also marked an “O” for “operational” on his master list of Washington engines, so he’s clearly familiar with the tug and I’ll ask him about it when I get back to Seattle.

Dirk heard that the Broughton Straits was later taken down to San Francisco a few years after he brought it to Port Townsend. He visited the Bay Area in 1994 and saw a mostly-sunken derelict that folks told him was the same tug. Another great old boat with a great old engine lost.

California readers, has anyone seen this derelict tug? We’ll send an Old Tacoma Marine Inc t-shirt to anyone who sends us good photos.

Dirk also sent us an interesting picture of an old Atlas-Imperial diesel:

This was taken in 1978 at the north end of Lake Union, probably in one of those lots off Northlake facing the I-5 bridge, just after it was “bulldozed off to the side of the property.” Dirk says he still has its control station.

2008 Week 30 in Review

Work on the Sobre las Olas

I spent all this week in Los Angeles, working on the Sobre las Olas (her name means “over the waves”), a beautiful fantail yacht:

All the pieces I shipped to California arrived, but I had a nasty surprise at the airport. Since when are you allowed only one check-in bag? At least all of the boxes were under 50 pounds, but the “extra” baggage charges nearly killed me.

Once on the boat, I removed the remaining relief valves and chased all the threads to be sure that all the parts will fit and are interchangeable (since it’s not a “spare part” unless it’ll fit anywhere you need it). I found that there is one set of relief valve and “tee” that are not interchangeable and must remain together, but other than that they all fit well.

In addition to the valves, I worked on the expansion tanks. The sight tubes were hard to see, so I swapped their locations. This would have been easy, except that several fittings on the tanks broke and I had to spend a lot of time trying to remove the broken fittings.

After the expansion tanks, I then installed the new water collection manifold, finished the cooling water plumbing, installed temperature gauges to each engine, and installed an air bleed line in the uphill side of the water collection manifolds.

I also did a lot of cleaning and painting. The Sobre is going to be featured in a boat show and I want the engine room and the two 6HM464 Atlas-Imperial diesels to look as nice as possible for invited guests:

The Portola for sale

I visited the Portola last week while in California. She’s also a classic fantail yacht (built in 1929), and is in perfect condition thanks to Rick, the owner’s son-in-law. He’s been working on it for about 25 years and knows it inside and out.

This week, she was hauled out at the Gambol Boatyard in Long Beach to replace some mildly compromised planks and perform the routine cleaning, painting, and re-zincing that all boats should have done yearly.

Charlie, the owner, has had the boat for most of his life and said he feels married to it, but he’s not using it much anymore. He feels that it’s time to find another good owner. Anyone looking for an elegant yacht should take a look at the Portola. It’s a comfortable, classy yacht, its original and historically significant Winton diesel runs great, and it has the parts and support to keep it running along time.

They’ve got a great website with lots more pictures here.

Bonus: mention this blog when purchasing the boat and receive a free Old Tacoma Marine Inc polo shirt to wear while yachting.

A visit to the Ready

I also took the opportunity to visit the Ready, a great tug in Long Beach powered with a 400 horsepower Atlas-Imperial diesel:

The new owner realized that the boat may be too much for him and may be looking for a buyer. If you’re interested in a project boat with an Atlas-Imperial, contact me.
