Several days before, the boiler was filled, a little oxygen scavenger added and I took it up to working pressure with the hydro pump to make sure all was tight. Water was dropped to a third glass.<br />
<br />
In true UK tradition, I lit it off with <i>Kingsford Match Light Charcoal ...</i><br />

In short order, the fire was over the grates and coal was added:<br />

Here's looking up through the stainless grate bars at a hot fire. In an hour, I had drafting steam, but didn't force it because I wanted to see how it would do naturally aspirated. In two hours, we were at warming through pressure (100-125), and shortly thereafter, the safety let go at 200 psi:<br />

I had told the Mrs, "Watch the neighbors (whose house you see) come running when the safety lifts." "Hey! You all right?!" "Yup. Just the safety." Another typical suburban Saturday ...<br />
<br />
A rain storm hit while we were firing things up. So the boiler was rained on, not for the last time:<br />
<br />

Some data:<br />
- Combustion chamber door never got above 350 F, so I'm pleased with the plenum insulation, etc. The door itself is still rather plain. So I'm imagining some bronze hand rails, a warming shelf for baked goods and maybe an espresso maker if I can figure out how to pipe it.<br />
- The boiler is more efficient than I imagined. The smokebox and smokebox plenum never got above 350 F. This will change under forced draft. The permanent stack will have a pyrometer so it can be monitored with greater precision.<br />
- With jacketing, I expect it to be more pleasant to be around. It was a hot day ...<br />
- Anthracite firing went as planned. This was pleasing as it is a compact and hot fuel. Plus it is local. A scuttle and a half (twenty pounds?) brought us to working pressure.<br />

It was sitting in the corner, collecting dust so I wanted to finish it.<br />
<br />
First to be finished was the smokebox:<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiDdrp3Q2F8u-UBv2AumA1IyqmmHj4L0WBSuppyjManioXHMm-ZCW7zhulydVmUGjM8TDlh_Mbx6-KGGp1u4zWOzrgBkKkrZ3I5geWc3k7cO3w7qZtkaWjOmIBSoH1mFWmTP0xqYNVgV0E/s1600/20180811_153506.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="1600" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiDdrp3Q2F8u-UBv2AumA1IyqmmHj4L0WBSuppyjManioXHMm-ZCW7zhulydVmUGjM8TDlh_Mbx6-KGGp1u4zWOzrgBkKkrZ3I5geWc3k7cO3w7qZtkaWjOmIBSoH1mFWmTP0xqYNVgV0E/s640/20180811_153506.jpg" width="640" /></a></div>

That's not a fire in the furnace. The shop is humid so a heat lamp keeps the local dew point from condensing on and rusting the steel. As was typical, the smokebox door is hung on hinges and secured with dogs. It can quickly be unsecured and swung up to snug a tube, clean the tubes or whatnot. The unfinished water glass is to the right.<br />
<br />
Here's another picture of the smokebox end with a temporary stack for fire up:<br />

<br />
Next was to finish the grate bearers and the grates. The grates are solid bar, UK style. In this photo, the firebrick is visible lining the combustion chamber. For anthracite firing, fire brick is essential for retaining and reflecting the heat. For hardwood, they could be taken out except for the furnace end wall.<br />
<br />

<br />
The grate area is two square feet with the brick in. Below's a picture of the combustion chamber before the reflective plenum is placed in. After the plenum was in, I sealed everything with a 5,000 F goo.<br />

Items of note: There's the combustion chamber seam cover strip to the left. Two angle iron supports, center and front behind the glass will support the jacket later. The insulation will be an inch thick. No one should have a cow about the piping. Except for the schedule 80 steel nipples, it is all class 300 bronze and brass.Anonymoushttp://www.blogger.com/profile/17090220291474935883noreply@blogger.com0tag:blogger.com,1999:blog-714141220547451818.post-13719713747593434292018-02-28T14:31:00.000-05:002018-02-28T14:31:07.675-05:00Feed PumpsPicked up some pumps ...

They were rebuilt by Kelly Anderson. Here's a shot of fitting the jacketing on the engine with temporary brass machine screws. It is finished now, though I don't have a picture. The jacketing is nickel with stainless screws.<br />

As for the rear seat, I made a template out of CDX that was lying around and fit it forward. Here's a photo of the port, fore seat template in place and fitting the port strakes:<br />

I threw some old 0.75" plywood I had lying around onto the floors. I was tired of sliding on saw dust into the bilge. The strakes aren't as loopy as the photo makes them out to be. Must be some kind of camera phone distortion going on ... Another shot looking forward:<br />

Everything is being made so it can easily be taken out of the hull for refit, renewal and whatnot. Hence, the reliance on bronze fasteners and seats made in halves. Once the seats are all finished, they'll come out anyway for primary piping runs and setting the boiler. The doors for the feed-water compartment, fore, are also finished. A photo of them will have to wait for another time.<br />

Each bunker will be accessed through a bronze deck scuttle. The bunkers carry around 100 lbs of coal. We'll see some day how far that gets us ...<br />
<br />
The bunker bulkhead is made out of mahogany marine ply 0.625" thick. The below photo shows it being fitted and mounted with temporary stainless screws. The bronze gates and slides are not yet in place.<br />

I forget whether I mentioned earlier - the steering station is a standard <a href="http://www.edsonmarine.com/marinestore/index.php?main_page=index&cPath=84_91_262_263" target="_blank"><i>Edson</i> bulkhead mount</a>. We had to re-machine the spindle for an antique wheel out of Greenock on the Clyde.<br />
<br />
Once a gate on the bunker is raised, the coal will spill out on the deck plate. Here's another shot:<br />

These are made out of leftover Honduran mahogany planking that was lying around. Here, the mahogany is being fit up:<br />

One can see that the steering gear is not hooked up yet. I had disconnected it while laying the deck. The chestnut piece running between No. 4 and No. 3 stations is a front seat support.<br />

Also, I had a seat idea that I was anxious to try. You see, it goes like this: The congregation where I served for a number of years removed two front pews for the usual reasons - space for more theatrics, weddings, worship combos, etc. I had reason to believe that the pews were American chestnut since much of the interior is finished in chestnut.<br />
<br />
Strapped to the roof of the mini-van, they made their way to the <i>The Works</i>, where they were stripped of cushions and disassembled. (True story: The two front pews were used since time immemorial - well, at least since 1925 - for the assemblage of the Sunday School children; boys on the right; girls on the left. The boys' pew had a reef of used chewing gum on the underside of the bench proper. Girls, of course, would have disposed of their chewing gum in the carefully saved wrapper.) The main seats were edge-glued, contoured chestnut.<br />
<br />
A template was fashioned and similar grain of sassafras was used to make up where the chestnut could not extend in width. I am reclining on the port side bench prior to its finishing:<br />

This is the fore deck as I was fitting the king plank. (Pay no attention to the 957 bronze dong - it is merely holding the plank in place.) All art is indefensible in a world of 24/7 news cycles, starving children and the like. But is has to be created, or else we succumb to the inhumanity of the age ... </div>

"What if you spill 20W oil on it?" a colleague (well, Kelly) wonders. Yes, and the Works could burn down. Art is always vulnerable. Natural teak is pretty resilient. This Spring I helped a couple of blokes deliver a yacht with a natural teak deck from Florida to Rhode Island. While refueling at sea, I spilled some No. 2 on the deck. (The scuppers were plugged up so none made it to sea - you turtle-huggers can stow your harpoons ...) The deck was discolored for a half a day, and then returned to its natural bleached tan. It's okay; teak has been a deck of choice for generations, and I believe it will serve <i>Iona </i>admirably. </div>

There, that got your attention. Now on to the more prosaic job of fitting cover board templates. Here's a shot of the very stern, where the aft quarter cover boards meet the stern king plank. The template material is adhesive opaque shelf paper. It's nice and stiff and I can see my marks through it. It also has handy-dandy grid lines on it. I have it tacked on to the sub-decking with brads. For finer cutting around the joggles, I use an Xacto knife. Of course the proof of the pudding will be to transmit the shape and cut to the planed, expensive teak planks. But this should minimize the error.<br />

Here's a shot of the starboard aft quarter plank template with a little more detail. Like the decking, there is room for a seam relief between the decking and cover board. When I saw these things out, I'll have to strike the balance between not leaving too much proud to work out later and cutting it close. But then, that's finish work everywhere ...<br />

One side is now done and we're wrestling in the starboard side. Cover boards are ripped and awaiting planing.

What a winter! The Works were locked in a temperature-induced, productivity death grip. I was able to continue slowly on the smokebox and boiler at work, but since that involves a commute, it is not near as handy. Below is a shot of the foredeck. The joggle fit and trim will be exciting to do. <br />

The king plank and cover boards are on hand and await planing to the same thickness (0.312"). The question was raised, "So how far can you bend that teak sideways?" On the stern deck, the curve is to a sixty (60") inch radius. One piece protested while bending to the dry fit. It shattered in my hand, not unlike glass. We were impressed.<br />
<br />
Another piece jumped the clamps - I'm not really sure how that happened - whirled through the air like a Venetian blind and landed butter-side up.

Here, Quinx is deep in her cups, polishing off the last of the eggnog.<br />

I took advantage of a relatively mild day to begin laying the decking. The sub-deck was warmed with heat lamps to help kick the epoxy. It responded admirably. I was surprised about the willingness of the teak to be bent laterally through as tight a curve as a 60-inch radius. In this shot, the clamps have been removed at the sweep of the bow. One can see the faint marks for the following planks, where they will rest against the king plank.<br />

The smokebox design then finally drafted by Mr Anderson, and the laser-cut pieces arrived, demanding attention and fabrication.<br />
<br />
Below is the incomplete furnace frame with the partial smokebox frame set in place to adjust fit. A hydraulic press punched the box frames for the door dog bolts. I'm tacking the pieces together by stick, later to be seal-welded with 0.023 MIG wire. The furnace and ash frames will be fitted with protruding sealing lips, and custom doors made with the appropriate drafting devices. To be fitting and welding again is a great joy.<br />
<br />
And yes, the boiler is on end inside the roof sheet of a Belpaire boiler, standing on its nose. A totally unrelated railway project ...<br />

Said gear runs the range from the practical - clothesline run through zinc-plated blocks - to the sublime - sailboat systems manufactured by <a href="http://www.edsonmarine.com/marinestore/index.php?main_page=index&cPath=84" target="_blank"><i>Edson Marine</i></a>. I admit I appreciate well-engineered systems. <i>Edson</i> had me as soon as I received their catalog. The heavy bronze quadrants; the exquisite sheaves - what could I do? I had to throw money at them ...<br />
<br />
After mounting the rudder, I came up with a system of blocks to act on the rudder. A port-side helm station was always the idea. The problem than became how to run the cables to the sheaves and the rudder quadrant. This first picture is the helm station, with the steering chain and cables emerging from its aft side.<br />

A standard <a href="http://www.edsonmarine.com/marinestore/index.php?main_page=index&cPath=84_91_262_263" target="_blank"><i>Edson</i> bulkhead gear</a> will mount on the box, with the proper fine wood and all. The standard taper didn't fit an antique wheel I received from Greenwich, UK, so we had to take the thing apart and machine the shaft. (I'm still not sure whether or not I'll use the brake, though it is set up for it.) The cables then lead aft to <i>No. Four</i> frame, in the foreground here, where two standard four-inch idler sheaves were set up to maintain the cable's suspension around the corner.<br />
<br />
Here's another picture of the <i>No. Four</i> sheave mount:<br />

Swapping orientation of the cables was then in order, as seen above, so that the bow swings in the proper direction with the wheel. Piercing <i>No. Five</i> bulkhead got me into the rudder compartment proper where I could thread the blocks which act upon the quadrant. Here's a shot of the stern compartment with the cables under temporary tension in order to see how the whole rig works:<br />

It was pleasing to manipulate the chain at the helm box and watch the whole thing silently swing through its paces, without slop. After determining that things would work, I then disassembled the cabling and idlers to seal the bulkheads where they were bored and to apply the correct fasteners. Jibes are coming about "a rig that will sail around the Horn," etc., but I don't believe I'll be using the emergency tiller any time soon.<br />

So it was off to get the keyway machined (courtesy of Mr. Anderson), and then back in the shop to be balanced, dressed and have a hole bored so the prop shaft can come out with the rudder hard over. <br />
<br />
Next was the trial installation. The hull was to be pivoted on its forward jack stands, so I knocked out the keel blocks forward of the stands and put the lift on bulkhead No. 5. Here we arrive at our final height, measured by the rule in the shaft hole, with <i>Quinx</i>, the shop cat supervising as usual ...<br />

The hull is home. I've not totally settled on the means of rudder suspension. A bracket with bronze collar will probably be on the underside of the king plank support, above the quadrant. The shaft extends a little up through the king plank for the possibility of an emergency tiller, should the steering gear fail. I'll figure on some kind of fancy bronze deck cover for it.<br />

After head scratching and fabricating, there will be future lifts for the final installation. That's when the packing gland, seen sitting to the right of the slings, will go in. <br />

Looks like the local graffiti artists have tagged the hull again. Not a bad sentiment on the kind of project that can tend to strain the checkbook and marital bonds ...

So out came the shaft hubs, recently machined, and the engine lift again, and all was swung inboard to begin the alignment process.<br />
<br />

This photo was taken when things were about dialed in, however it shows the many considerations in play: The engine is in its position fore and aft. Though the floors are fairly true to the gunwales, I nonetheless strung a straight edge* across to make sure that the engine would be perfectly perpendicular to the plane of the waterline. I would see where the engine was sitting with respect to the shaft hub, lift up the engine a piece, knock the beds out and plane them to where I thought they should be, re-install them, measure and fuss, lift the engine a bit, knock out the beds, etc. *(Purists will worry about my use of a treated piece of junk pine for a straight edge, but I couldn't find my prized Doug fir batten ... One grabs what one can in situations like this.)<br />
<br />
Finally, I had things to around 0.005" on the tips of plastic epoxy spatulas, confident that permanent shimming could be accomplished from there. Here's a close up of the hubs all but dialed in - bright engine hub forward and gray shaft hub aft - with the spatulas serving a nobler task than normal. The hubs by the way, are off the shelf, <i><a href="http://www.buckalgonquin.com/" target="_blank">Buck-Algonquin</a></i> ductile iron, cast within a couple miles of our house. The shaft hub remains stock while the engine hub has been extensive modified to clear eccentrics, retaining nuts, etc.<br />

To the port of the engine, forward of the aft floor behind the low pressure column is where the crosshead-driven pumps will sit on their bronze bedplate. This bedplate has to be let into the beds its thickness. So, the lift whisked the engine back to the bench, out came the beds for the last time and out came the chisels. With the beds then finish dressed, I epoxied them into place. The beds themselves were left unfinished except where the bonds on the tenons and and floor shelves were made. Later, I'll treat them with raw linseed oil and turpentine - love that old boat smell!<br />

The hubs, bearing caps (here, in red) and other items will go out to the powder-coating shop for their final finish. One can see the pump links, and other items, namely the exposed low-pressure valve seat on the yet unfinished engine.<br />

The cost was cheaper than the scrap value and I had done enough reading on props to know that the prop had an rpm-limiting disk area, among other issues ...<br />
<br />

<i>Iona</i> didn't mind, I wasn't afraid of modifications and there were enough other things to do so the prop collected dust.<br />
<br />
Fast-forward to now - the propeller shaft is in - so it was time to re-visit the propeller. Back to the bookmarks in the propeller tomes. I decided on a surface area, plotted where I would modify (increase) the pitch and made a template.<br />
<br />
Out came the center punch; a cut-off wheel was mounted on the small grinder - It was "bad haircut time."<br />
<br />
Here's the prop with a "bad haircut." I know about these things. Summer of '70, the neighbor boys and I purchased black powder from the feed store. You could do that kind of thing in those days. We perfected our copper tubing skills by manufacturing bombs of various caliber and force. Turns out we were challenged by that age-old problem of proper fusing. (If we had only had the Internet!) One of our devices experienced a premature - to us - detonation. Half my summer-blond hair was frizzed. Not to mention the powder grains embedded in temples, cheeks and shins. [We are far afield from steam propellers ...] It was the kind of thing the parents would certainly notice. What to do? Haircuts! Of course, no one would notice! So we similarly afflicted youth set about shearing each other - what could go wrong? Followed by thorough scrubbing of the powder burns; there, we looked like we were ready for church ...<br />

The photo doesn't do it quite justice: the chord is as thick as my little finger. The next step was to grind a rolling foil from root to tip in a way that created lift or thrust on the back of the blade. By dressing the foil in the way I imagined, it would increase the pitch slightly. Oh, and I chopped the tips to fit the aperture. Here's the first blade, with foil dressed. (The tips will wait for balancing.)<br />

This photo uses different lighting and displays more of the overall profile. I might keep the squarish tips, after a fashion. They might add to "the look" whatever my profiling skills lack. By the way, tools used were 4.5" grinder with razor cut-off wheel; 4.5" grinder with standard 0.250" wheel for roughing in; 7" slow-speed grinder with foam pad and 80 grit stick-on pads for fairing.<br />
<br />
Balancing and final tip dress will take place on a motorcycle wheel balancing stand.<br />

The Wooden Boat Show at Mystic has become an annual pilgrimage for us. The salty ambiance of Mystic would be enough. The first half-day is spent wandering around in a daze, just glad to be there. But then I settle down to <i>Purpose</i>; re-visiting certain vendors, taking pictures of design elements we like, and shopping.<br />
<br />
Seats and decks were on my mind ... Here's a simple but elegant presentation.<br />
<br />

The benches are easily constructed with turned spindles for support. The teak floor boards lift out, where appropriate.</div>

This teak deck is left weathered, with narrower boards than the standard. I appreciate the way it is let in around the bright house. Further inspiration was found in the Rossi storage area. These are boats and items that are not on display but are available to study.</div>

Seat detail from an early 20th century launch - perhaps my favorite design so far. The storage collection is surreal. What is this? The jawbone of a whale?</div>

Best beloved found a marine consignment (!) shop in Mystic and was sweet enough to tell me about it. Here are some finds on <i>Iona</i>'s stern planking. The stern bit is close to its future home.<br />

The ASME symbol, with an "S" below it. <br />
<br />
No bottled goods were broke over the shell of the boiler, but it is still exciting. I mean, who gets to attend a boiler stamping these days?<br />
<br />
Ceremony over, we poured over the P-2 form, more painful than federal taxes, in order to make sure that every "i" was dotted and "t" was crossed.<br />
<br />
I am told that the reviewers on the Board are humorless ...<br />

Oh! Maybe it's the shaft! Sure enough, propped inside the shop door - the delivery man is well-trained - stands the new shaft in its tube. Soon it is out of its packing and I'm checking the specs and fit. This is good ...<br />

Here is the shaft poking through the gland. The keyway for the coupling is clearly visible on the top. Since the gland with its O-rings floats in the stern tube, I loosen all of the bronze machine screws that fasten it to the tube and slowly torque them in the pattern that is best centered on the shaft. It rotates freely. The packing nut is on the gland though the packing has yet to be laid in.<br />

Here's a shot of the interior with the shaft protruding forward. The locking nut for the gland is on a seat support. The wide angle lens of the camera makes the launch look like a barge. The first coat of the interior paint is down - <a href="http://www.yachtpaint.com/usa/diy/products/finishes/brightside-polyurethane.aspx" target="_blank"><b>Interlux</b> <i>Grand Banks Beige</i></a>. I used this paint since it will be kind on the eyes and easy to freshen up before each season. Though as one can see, it will mostly be under floorboards and seats. The bilge will stay bright white epoxy for ease of suging.<br />

Here's the shaft protruding from the cutless bearing. I'm still deciding whether to use low-heat epoxy to bond the bearing in or the time-honored set screws. After we make up our mind about that, I'll finish touching up the copper bottom paint. Then, after the packing is set up, it will be time for a float test!<br />

It's almost <i>Boiler Inspection Eve</i>. Saturday, the three boilers were plumbed in series in preparation for the official hydro and inspection. All three are wearing their blowdowns. Mine is last in the series with the air vent and the gauge. And yes, reasonable people could differ about the placement of the blowdown - pressure on the bonnet and the packing - what is this world coming to? <br />

Spiders and silverfish were sent scurrying as the engine lift raised first one end and then the other as I followed with the jackstands. The previous weekend I had gotten the engine beds out of some old-growth Doug fir I had lying around - actually leftovers from the stem piece. Here, my heart is in my throat as I lift the uncompleted compound over the gunwales and down to the beds:<br />

The object of the exercise is to dial in the fit for the propeller shaft. Once the shaft is installed, further fitting of the beds may be pursued. The engine swings down into place ...<br />

The tenons of the beds are plainly seen in No. 3 floor. The beds are just sitting in there since they will have to be planed and jiggered quite a bit. Almost there ...<br />

Once on the beds, I get to work sliding the engine aft and positioning the story stick in the shaft log for calculating coupling lengths, propeller clearances, etc. How does <a href="http://www.pacificmarine.net/engineering/propeller-and-propeller-shaft/sae-specification-j755-propeller-shaft.htm" target="_blank">SAE 755</a> go again? So much to remember ... Here's a shot of the stick in place and my rule checking on clearances for the engine pumps. I had planned for all of this previously when laying out the shaft log angle, bed supports, etc. Still it is gratifying to see it all work out with the actual hardware. At this point, the beds are still 0.125" high from the plane of the shaft log. Pitch and roll on the beds remains to be dialed in, too.<br />

The starboard bed is too thick and does not permit much lateral adjustment. The engine is hoisted to take weight, out comes the plane and then the bed is tapped back into place. Good, now there's more room. The story stick has been replaced by a 1.25" dowel just to see how far we're off. Final adjustment won't come until the shaft and couplings are in place, with a final review afloat in case the hull flexes in displacement.<br />
