All over the map

As Quentin often reminds us, all boats are built in the last month. CWM is no exception, and the pace around the shop has risen noticeably. Here’s a smorgasbord of the kinds of things going on.

Electrical work

We’re putting in generators and batteries for more than the nav system. The boat has always had electric lighting, but it all needs to be upgraded to pass muster for going to sea. We’ve found lots of fixtures that have been pulled from other boats by salvagers in India.

Some have been pulled from Morgan or out of our own collection to be assessed. Scott and Bobby look over the collection.

2014-IMG_0323 2014-IMG_0320 2014-IMG_0286

Nathan has spent a good amount of time cleaning up some of these.

2014-IMG_0054

The housings were cooked is TSP to loosen the paint.

2014-IMG_0051

Yum.

The lanterns will be retrofitted with LED lights.

2014-IMG_0321 2014-IMG_0324

These lights are cooler and safer than oil lamps, and they are brilliant and energy efficient to boot.

All of the wiring on the ship will be upgraded to marine specs.

2014-IMG_0234

It’s far more complex than you might think. Few if any of the parts needed can be bought at your local hardware store.  Even the wire is special.

Metal work

There’s all sorts of fabrication that we’ve been doing lately. You’ve seen some of the shivs for the steering gear in past posts. Here Jim is turning some stock down on the metal lathe,

2014-IMG_0415

and drilling out holes on the Bridgeport.

2014-IMG_0414

Blocks have been refurbished from the inside out.

2014-IMG_0442 2014-IMG_0451

We’ve made lots of hinges for sea chests.

2014-IMG_0511

These hinges are completely traditional, including the forge welding that forms the hinge loop.

2014-IMG_0538

Here’s Ali working at the Seaport’s forge. First, she cleans up her fire by pulling out the “clinker,” the fused coal residue that doesn’t contribute to the heat of the fire.

2014-IMG_0543 2014-IMG_0550

She concentrates the coke, or heat-producing coal in the center of the fire and brings some green coal to the back to bank the fire and begin the coking process (cooking out the impurities) of the green coal.

She’s previously shaped and folded her barrels at the metal shop, but the overlap needs to be fused together.

2014-IMG_0552

The piece is put deep into the fire and heated to almost melting.

2014-IMG_0554

She quickly pulls the piece out of the fire, and coats it with flux to stop the oxidation (the hot metal reacts with the oxygen in the air and forms iron oxide, aka rust. This oxidation would become a barrier to keep the 2 metal leaves from fusing.) reaction.

2014-IMG_0559

What does she use as flux? You may know this stuff.

2014-IMG_0555

Back into the fire. Once the piece is just hot enough, things move quickly.

She and Mike have made all sorts of other parts. Here they are taking flat stock and opening up the holes to make square washers. First, heating and flattening the stock.

2014-IMG_0660 2014-IMG_0655

and then driving a pin through the hole to open it up.

2014-IMG_0657 2014-IMG_0658

Yes, we make some of our own washers.

There are many deadeye and bullseye bands to make. Sometimes it’s pretty obvious why.

2014-IMG_0959

The big metal cone is called a cone mandrel. If you’ve ever had a ring resized, the jeweler used a smaller version of this same device.

2014-IMG_0950

It helps to form an even, round curve.

All those fine shapes formed by heat and hammering.

2014-IMG_0952 2014-IMG_0957

2014-IMG_0960

The final product after being fit around a bullseye.

2014-IMG_0962

The other day we needed to extend a bolt coming out of the try works. The original had degraded and would no longer hold a nut, so Scott and crew welded a new section of bolt onto the old shaft.

2014-IMG_1158 2014-IMG_1160

(Jack is helping and has his eyes tightly shut by the way)

A little more tuning up.

2014-IMG_1164

And there you go. One extended bolt.

2014-IMG_1166

These bolts are used to attach the large iron brackets that fasten the try works to the ship.

2014-IMG_0983

Sea Chests

The volunteers have been working steadily on sea chest for the voyage. They’ve built over 30 to date.

2014-IMG_0890 2014-IMG_0992 2014-IMG_0993

Some are brightly painted

2014-IMG_0697

and others, more conservative.

2014-IMG_0443

They all have a till with a hinged top for smaller items.

2014-IMG_0444 2014-IMG_0445

Dean has made all manner of fancy beckets (lifting handles) for the sea chests. These are real works of art.

2014-IMG_0441 2014-IMG_0495

The Hold

Lots of work down here. Bob and Trev have almost finished with the platform that will cover the ballast.

2014-IMG_1017

Each section is removable for access to the bilge and for trimming the ballast when we get down to New London.

The entire platform rests on a series of athwartships beams

2014-IMG_0879 2014-IMG_0805

that land on curved, beveled timbers fastened to the ceiling. Here is one being cut on the ship’s saw prior to final fitting.

2014-IMG_0479 2014-IMG_0481

You can see them in place here.

2014-IMG_0637 2014-IMG_0523

The timber also acts the brace the concrete ballast and keep it from shifting.

The hold looks a lot different than it did back in 1969 when rocks were used as ballast.

2014-IMG_0486 2014-IMG_0484

Access panels are set in place above the sea cocks (water intake valves).

2014-IMG_1018 2014-IMG_0859

Scott has been doing a lot of work in the mechanicals room where the generator and pumps are located. He’s fabricated this fine battery rack that fits against the curved ceiling.

2014-IMG_0097

He, Paul, and others have done a tremendous amount of plumbing work over the past month. Here’s a manifold that directs water in from the various through-hulls.

2014-IMG_1140 2014-IMG_1013

There’s a lot more beneath the decking. It takes some serious contortions to work down below the mechanicals room.

2014-IMG_0880

Yes, that’s Paul down there, just about to go below the platform.

The pumps are all connected up now.

2014-IMG_1021

Fire suppression, exhaust, fuel lines, wiring… it’s getting busier and busier in here.

2014-IMG_1020

The fuel tank and filter are now installed.

2014-IMG_1019

Paul has added sound insulation to the mechanicals room.

2014-IMG_0865 2014-IMG_0862

and will soon cover it all over with shiplapped pine.

2014-IMG_1012

Scott built a snazzy control panel for the diesel fire pump,

2014-IMG_0861

and it works just fine. Here’s the engine starting up for just the second time.

It’s Loud.

Bringing in the crane

The crane came by the other week and lifted all manner of things on board. Matt and the riggers coordinated a mountain of projects, and pulled them all off in a single day. There were piles of davits (to hold the whaleboats) to go in.

2014-IMG_1055 2014-IMG_1059

More ballast to go in the hold.

2014-IMG_1053 2014-IMG_1052

The old carpenter’s bench / chicken coop (yes, really).

2014-IMG_1060

Mrs. Tinkham’s Cabin.

2014-IMG_1062

Mrs. Tinkham was the 19 year-old wife of Captain Tinkham who came aboard as a newlywed in 1871. She was sea sick for the entire voyage, and the captain had this cabin built for her up on deck, presumably to give her more air. She left the ship after a year and half of being sick (!) but the cabin was found to be useful, and so remained.

All of the water and waste storage tanks went in.

2014-IMG_1043

2014-IMG_1037

It was a tight fit at times,

2014-IMG_1040 2014-IMG_1038

but they’re in now.

2014-IMG_1071

They’ll be moved to the centerline of the boat soon.

That’s it for now, but there’s more that I haven’t covered yet.
