Wooden Boat Plans Australia | Super structure metal work is finished

| 0 komentar |

Wooden Boat Plans Australia


Tomorrow morning, before I take off for work, Im going to spend an hour or two so I can clean and organize the shop now that the metal work is completed. Im ready to prep the super structure for paint so I need to put away all the tools Ive been using to do battle.

Im a little blown away with how long it took to get the metal work completed. I did have a major set back in that the rough openings for the windows were cut for a four inch radius, and the windows are built using a six inch radius. There are 17 windows in the super structure and the repair consisted of me using my plasma cutter to cut out the 68 corners out of the existing rough openings. I then cut 68 new radius corners and welded them back in to the openings. The windows in the salon were easy as they were all square. The windows in the pilot house were a bit more of a challenges as they are all parallelograms, and required a little bit of noggin work to get the angles along with the radiuss correct. But, the window openings are now correct and all the widows fit the way theyre supposed to. Along with repairing the window openings, I added 60 or 70 more tabs to the window openings to bolt framing lumber to. 

 


 


 
 
 

Another job I got finished was fabricating the Tabernacle for the mast. After some indecision and talking with some other builders, I decided to go with a six inch mast. The primary function of the mast is going to be used to hoist my skiff to the roof of the salon. I am also going to have my radar mounted on the mast, and some lights and antennas. My long term plan regarding the mast is to be able to use it for a future para vane rig, and at a minimum, a flopper stopper rig. The Tabernacle is built out of 1/2" stainless steel. The pins used to hold the mast to the tabernacle are 1.25". The tabernacle is centered on frame #13. The tabernacle also has a doubler plate that it sits on and by doing some additional framing and reinforcing, I am spreading the load of the tabernacle to two additional frames, #14 @ # 12 . The bracket that will hold the para vane pole is also connected to frame #13 with solid 1/2" plates. I increased the flange thickness on # 13 to 5/16, and all is a continuous weld  were the reinforcing occurs. Two frames aft of the main para vane bracket, sits another bracket for another pole that will act as a brace for the main pole. The bracket for the brace is also connected to the frame with 1/2" plates. To connect the stays and shrouds, I welded 1/2" stainless pad eyes to frames.  I have two shrouds on each side, and one fore stay. I dont know if Ill ever use a para vane rig, but I do know Ill use flopper stoppers while at anchor. I had an engineering friend of mine give me some advice with beefing up the structure, and I feel good that I have things beefy enough. A fair amount of time and fabricating went in to this part of the boat. Because I will have electric winches for the mast/boom, radar, and some lights, I welded a 1.5" stainless nipple next to the tabernacle to run the mechanicals. I positioned the nipple so that  I can bolt a 6"x6" splice box to the tabernacle gusset, and use a grommet to make a water tight seal to the nipple. Ill use good quality cord grips to bring the various feeds out of the splice box.

The other job I  did was increase the width of the door at the salon to 32". Ill be fabricating the aluminum door, so I feel OK with the increased size. I plan on  having at least two dogs in the door to help hold it fast. Along with being weather tight, I want a door that will keep the thieves out.

Im using composting toilets on board and each one of those requires an 1.5" vent. I made those vents out of sch. 40 stainless. One is welded in to the soffit above the salon, and the below deck vent is welded in to the front of the wheel house.  Ill use PVC to connect the toilets to the stainless stubs I welded in the hull.

We have a shower for the cabins below deck, but due to the size of my posse, I felt it best if we had another shower on board. The easiest place to do this was on the aft deck in the port side corner of deck on the salon bulkhead. This will be a hot/cold shower. I fabricated a stainless shelf with a lip on it to retain soap, and a bar for wash rags and to hold back shampoo bottles.

I installed a 4" stainless vent for our 230volt clothes dryer.

On the aft salon bulkhead on the aft deck the fuel fills and vents reside. There is a two inch fill on both the port and starboard side. Next to each fill are the vents for the two port side tanks and two starboard tanks. The fill and vent pipes are welded in place. I really need a box around each set of pipes, similar to what Peter did on Koala ( now Kame Hele... not sure of the spelling). I have a little bit of time left where I can fabricated these boxs, and I might try braking them over the work bench. If not, my neighbor will do it on his press brake.

Outboard of the fill and vents are the two three inch vents for the lazzarette. These are weld in place.

I welded the six inch vent intakes for the master cabin. These vents are in the foreword wall of the wheel house.

To get up on the the roof of the salon, Im going to gain access via the wheel house side deck. Because of the raised pilot house, a five foot tall ladder is all that is needed to get on to the roof. I fabricated and welded some brackets to the salon wall to pin the removable ladder to. Its hard to describe it now, but because of the bulwark, and how I plan on working the salon roof hand rail, this will be a safe, secure way to get up on to the roof. I was going to get fancy and use a torsion spring to have the ladder self stow up on the roof, but my short time frame killed that idea and I decide to stow the ladder on  stainless post welded to the front of the wheel house. The forward  rake of the wheel house windows along with the almost 5 distance to the Portuguese bridge will allow all to pass by this area without bumping the ladder. It will make more sense once the super structure is welded to the hull.

Because I moved the aft salon wall, I had to cut the panel that extends down the salon line towards the aft deck. One of the boarding doors conflicts with this panel, so I cut it to fit. I gave this cut a nice looking radius where it meets the aft deck roof. It was important to me to keep some protection of the aft salon wall at this area, so we still have an inside corner where I cut the panel to accommodate the boarding door. Because both the port and starboard side panel are 3/16 material, I decided to treat each edge with a 1/2" stainless round bar. The round bar treatment should come in handy on the side where the boarding door is as this area will get some abuse. Hopefully, the stainless round bar helps with decreasing my  maintenance painting. Every exposed, exterior edge on board, has a 1/2" stainless round bar welded to it.  

I used 70 lbs of .035 welding wire to build the super structure. Im not for sure, but I think I drilled darn near 500 5/16 holes for bolting framing lumber to the steel frames. I might have drilled more holes, but Im going to order 500 2"x1/4" carriage bolts, nylock nuts and washers and see how that works out. 

As of today, my paint schedule is going to be blast the metal followed by two coats of epoxy primer. The inside of the super structure will get two more coats of Alkyd Enamel, then the framing lumber gets bolted on followed by spray foam. The roof of the super structure will get blasted followed by two coats of epoxy primer then three or four coats of Acrylic Urethane. Ill probably put a non skid on the roof, but that wont happen until after launch. The outside of the super structure will get blasted, two coats of primer, two coats of high build primer, fair ed, more primer to seal the high build, then top coat with three or four coats of Acrylic Urethane.

The last job I did to get the super structure ready to begin paint prep was to have my daughter and her friend Olivia walk around on the roof so I could fix the six or seven areas that were "oil canning". All that was required of that job was to find the offending areas, then weld a 1.5" flat bar between the longs and pull the roof sheathing down and weld it to the flat bar. Pretty easy job, but it still took us about three hours to wrap it up.

As anyone can imagine, Im glad to have this part of the job behind me. Paint and paint prep is going to be nasty, but I can now see the bitter end. Maybe by early October, Ill be able to post some sort of smiley face as I should be starting to take the front of the barn off.

Boat Plans Wood | Photos Of Metal Wastage Caused By Trapped Water

| 0 komentar |

Boat Plans Wood


Here are some photos of what trapped water and moisture will do to a metal hulled boat. This is not to meant sway anyone from buying or owning a metal boat, I own one myself. It is to give all of us a reminder though, that we need to be diligent in maintaining and inspecting our boats. Speaking of inspecting a metal boat, I had a very good comment on the last post from a former client. He has a process that is very impressive when it comes to inspecting a metal boat for purchase. I encourage anyone who is wanting to buy a metal boat or any boat for that matter to do their own close inspection before putting an offer on a boat and hiring a surveyor. I also would advise the seller of a metal boat to hire a surveyor to inspect the boat before listing it. It is important any issues are known about before the boat goes on the market. Too often a person turns down a boat during my inspections. I would much prefer to be part of a happy exchange of a boat then not.

Saltwater was trapped in a keel of an aluminum boat that was filled with foam and lead. The boat got a new redesigned bulb keel.

This is where salt water has dried in a bilge of an aluminum hulled boat.

A view from the exterior of the same boat.

 

This is where water had sat for years on the inside of this steel boat, good news she was made as good as new.



A lot of time these problems are found while the bottom of a boat is sandblasted or a paint blister is ground down for a repair. Which is what happened in the photo below.

So what do we do to make sure we can find these problems?

Refer to the previous post for the answer:

Boat Plans Arch Davis | Ive started painting the super structure

| 0 komentar |

Boat Plans Arch Davis


The interior of the super structure is painted and once again Ive discovered the hard way just how big a boat this is.

To begin, I am changing the paint schedule. After speaking with a commercial boat yard, they have me convinced to  only prime the interior of the super structure. The interior metal will get covered with closed cell spray foam then the liner will go over that. There is nothing such as UV or physical abuse that is going to break the primer down, so a top coat of paint is really not needed. I gave the interior a thorough blasting and applied three coats of epoxy primer.

Because I  have to weld the super structure to the hull, I taped off the the bottom edge of the metal so I will not have to grind away the primer later. Having the prime being burnt off by the welding is not only nasty, it can lead to the  primer gas mixing with the weld shielding gas and cause a defect in the weld. Porosity of the weld would be one example of a defect of this nature. Taping the joint is a heck of a lot faster and easier vs grinding.

Because paint over spray is not an issue with the interior, I decided to do this area first. Acting on the advice of some experienced paint people, I have taken a different approach to painting this part of the boat vs the hull. When I painted the hull, I blasted then primed, then started doing my fairing and filler work. The paint guys talked me into blasting the joints I want to do filler work, applying the filler, then blasting the rest of the metal then priming. Doing the work in this order will save me time as I will avoid some scuffing. This order of work will save me the most time on the roof. I  have a few areas I want to do some filler work on so I blasted those areas clean, and applied some filler. The filler work Im doing on the roof is more for function than for aesthetics. Ill sand those areas smooth, blast the rest of the roof, apply two coats of primer, and within the 72 hour chemical bond able time limit, Ill top coat the roof. No scuffing will be needed, and the more reliable chemical connection between primer and top coat is achieved.

The sides of the super structure is the area that everyone is going to see. For the sides, Im blasting all the joints and welds I want to fill over, then Im applying filler. Ill sand the filler smooth, blast the rest of the sides clean, and two coats of epoxy primer. While the primer is still hot, Ill apply two coats of sand able high build primer and long board that coat smooth. I know Ill be doing some more filler work on top of the high build, but thats  to be expected to get a nice finish. Once Im good with the high build surface ( my version of good is different than a professional body mans version). Ill spray another coat of primer to seal the high build, then top coat with my off white Acrylic Urethane. At this point the paint will be finished, and the list will be that much smaller.

Ill be posting updates as I work through the roof and sides.

The move to the launch site continues to get pushed back further. October seems doable, but early November seems more realistic. Once the paint work is finished, there is still work to be done here in the shop that will make the launch site assembly go faster. There is really no reason to slow things down by getting in a hurry. This is a big ass ed job, for one man to do by himself, and the time it takes is going to be the time it takes. I can only hope that the crap weather holds off until I have her dried in at the launch site, but Ive worked my whole life out in crap weather, so Im not to worried about me. I just dont want to compromises any work on the boat nor cost myself extra money.

Ill have the roof blasted and primed this weekend, and if all goes well, well have a off white roof to look at come Monday evening or Tuesday morning.

 






Cheers

Boat Plans Stitch And Glue | The need of keeping water out of the bilge of a metal boat

| 0 komentar |

Boat Plans Stitch And Glue


I always start my surveys on metal boats by using Thermal Imaging of the hull. This helps me locate the structural components of the metal boat. I am also looking for trapped moisture and/or water. If this is found, then there is a good chance there will be corrosion. Next I conduct an inspection of the bilge of the boat, including, anchor, sail, cockpit lockers, and lazarettes. Now I have a very good idea where to concentrate my UTM-audio gauge. I take readings of the whole hull, but will do more readings in the areas of concern.

When I see water in a bilge of a metal boat beyond what might be in a sump I get concerned. I would like to see dry bilges on all metal boats, but this is not always possible. On Tuesday I surveyed a steel trawler. Overall this boat looked to be in fair condition, but then I saw the water in the bilge, a lot of it! There was heavy scale in some areas because of the standing water.  I knew this was an area I needed to spend some time getting thickness readings.

The next day I did my audio gauge. My readings indicated plate wastage. In some areas I could not get a reading that most likely is caused by heavy scale. My visual inspection from inside confirmed the heavy scale. When I arrived at the boat I noticed some weeping from what I hoped was paint blisters. Then an hour later water stared streaming from one of the blisters. Just to think only the paint was holding this section of plate together.

The good news! The boat was out of the water it will not sink. Steel boats can fixed; by cropping out the bad plate and adding new. In a short period of time, she will be underway again.

The moral of this story? If you own a metal boat keep an eye on the bilges.

I will post photos in my next post.

Boat Plans Wooden | Applying Thermal Imaging To Metal Boats

Applying Thermal Imaging To Metal Boats

This was a topic that fellow marine surveyor Jack Allinson and I presented at the 2013 IBEX ( International Boatbuilders Exhibition & Conference). I am new to thermal imaging, but over the past year Jack Allinson has proven its worth when it comes to metal boats. Mr. Allinson has been applying thermal imaging to marine surveying since 2003. Here at DBYS I am working on my Level 1 certification and have acquired a Flir Thermal Imager to add to my tool box for my metal boat inspections. Thermal imaging or also known as Infared Thermography, has been used in factory inspections, home inspections and marine surveying of composite boats for years.
When we apply it to metal boats it gives us  "better set of eyes" along with visual inspection and audio gauging. We have found that often where thermal anomalies are found there is trapped moisture and/or corrosion, and paint voids. One of the benefits is the ability to see the structure of the boat and location of the tanks. I find this very helpful to speed up my layout for UT/audio gauge inspection 

  From our presentation:
Infrared thermal imaging and correct interpretations of surface thermal patterns can be a real boon to cost-conscious clients keen on the price point required to find metal wastage, trapped and hidden moisture, and to document the water routes (trails) created when dewatering a vessel. On most UTM jobs, as much as 60% of the work effort goes into planning and implementing where to take the random spot checks for plating thickness. With the right environmental conditions this work can be easily reduced by half by scanning the shell plate with an infrared thermal imager.

 

In the images below the transverse framing and longitudinal stringers are visible.  I will post other photos at a later date that I have been able to locate corrosion.

Wood Boat Plans And Kits | Wrapping up the super structure metal work

Wood Boat Plans And Kits


Getting all the little odds and ends completed before I can paint the super structure is taking quite a bit more time than I had anticipated. Im trying to work out a few problems as once I start paint prep, I dont want to stop to do some welding. Once the boat is at the launch site, I have a feeling Ill be doing some welding I forgot on the super structure, but my hope is that I get it all figured out now.

The first thing I did on the super structure was to install a temporary floor in the wheel house to bring  things close to the finish floor level. After I had the wheel house floor back up to grade I installed all of the cleats and tabs I need to bolt the lumber to. Trying to use up what material I have on hand, I cut my longer pieces of flat bars in to tabs, and wherever possible, used the tabs welded in place to bolt lumber to. Once I have the interior painted, Ill bolt lumber to the tabs and cleats, then have the insulator spray foam the interior of the super structure.

 Im limited to the wall thickness around the windows to 2.25" due to using the clamp rings. The clamp rings will make for a nice neat finish, but I wish I would have been able to get the rings for a 3.5" wall thickness. Im able to make the wall thickness on the front of the wheel house 2.25", but the rest of the boat is going to be thicker due to the framing, so Ill have to build some custom wood trim rings to tie everything together.

Once I had all the cleats welded in place I turned my  focus to the welding needed to be done on the super structure roof. The roof work has turned out to taking a little more time than I had thought it would. I am planning for using a LP fired stove in the galley, and I needed a place to store propane. I framed a propane locker on the roof that will be large enough to store two bottles. Even though Im not going to be doing any fairing work on the roof, I used pipe to make the corners of the propane locker. The pipe corners will paint up nicely, and will require little fairing to make them look good and cut down on future maintenance. The locker has two drains to let wasps in and water and any propane that could spring a leak out. I welded a 1/2" stainless nipple in the bottom of the locker to allow me to plumb the propane supply line in to the galley. The lid for the propane locker will be a simple lid with two pins for hinges and a simple latch.

In the center of the super structure sits the exhaust stack funnel. Im using a keel cooled main engine and a dry exhaust system. The exhaust system is basically like a truck, and uses a pipe to bring the exhaust up and out of the boat. Along with the exhaust from the engine, Im using the exhaust funnel to vent the hot air out of the engine room. I also am using the exhaust funnel to bring cool air in to the engine room. In order to do this, I partitioned the exhaust funnel in half, with one half dedicated to getting hot air and exhaust out of the engine room, and the other half for bringing cool intake air into the engine room. The largest hole I could cut in to the exhaust funnel at what I would consider an elevation where the hole would actually do something was 12"x16". So I have a 12"x16" hole for the intake, and the same for the hot air exhaust. I purchased a cheap coil stock louver from Lowes to see how it would work out, and Im going to buy some better quality louvers for the final install. Ill probably use the cheap louvers over the winter just to keep the weather out. Removing the louvers is also how Ill gain access to clamping the exhaust pipe to the 4" stainless pipe I welded in to the exhaust funnel top.

I like the way the exhaust funnel looks and in order to keep things looking good I had the metal formed on a press brake. The fab shop owners is one of my neighbors and it was fun helping him do this small job for me. The exhaust funnel is tapered so there are two different radiuss on the piece. In order to get the different radiuss Mark set the machine to hit harder on one side than it did on the other. His machine is a Cincinnati 300 ton press brake, and was built in 1942. Cincinnati is a good brand, and this machine was built in a era in this country that has faded fast. We need our manufacturing jobs. Mark laid the pieces out for 20 hits per piece, and in this picture, you can see him lining the die up to hit on his punch marks.

I welded a four inch stainless pipe in to the exhaust funnel. Im thinking about running the exhaust stack up the mast, and if I do that, Ill probably either do that in chrome or stainless. If I dont run it up the mast, Ill clamp a stainless or chrome 45 on the the nipple and call it done. I have room for a silencer on the exhaust piping, but for right now, Im not going to install one. If I run the exhaust pipe up the mast, the outlet will be so high and with the wind blowing the sound away from the boat, I doubt youll hear it. You might hear the whistle from the turbo, but I think that sounds good. I can always add a silencer if I need to, I just would rather not as they get hot and its just one more thing to buy and maintain.

The inside of the exhaust side of the funnel will be  insulated to help keep the heat headed up and out. Ill post more on this later down the road, but Ill be using some fans in the engine room to help air get in and force warm air out.

The salon roof is where well be storing our skiff, bikes, and kayaks. Because of having to work up there, I decide to install a hand rail around the salon roof. Im not ready to install the hand rail, and really dont want to do that job just yet, so I decided to cut some 1.5" discs to act as a doubler for welding the 1"  handrail stanchions to. By using the doubler discs, all Ill have to do is sand the paint off the disc and weld the stanchion to the disc. The disc will act as a heat sink and not burn the paint from the outside or inside of the roof. Ill be TIG welding ( Norm F. @ Kevin M ) the hand rail together, so splatter will not be an issue. I cut the disc on my mill using a hole saw and cooling the bit with water. The disc will also look decent with the hand rail stanchion, will not look like an afterthought, and allows me to keep things moving as doing this work is a hell of a lot easier with the hand rail not installed.  As per my locating the hand rail stanchions over a frame, I have kept in line with over building everything. The hand rail stanchions ended up being 30" on center.

I also will need a cradle for our yet to be designed skiff ( Kevin M), so instead of figuring out a cradle for a skiff I dont own yet, I just welded some 12" long x 3" wide doubler plates where I plan on building the skiff cradle. A 12 long skiff will fit nicely, but a 13 would also fit albeit tight. Im going to build the skiff in aluminum, but that wont be for another two years. Getting a little off subject, I sure would like to weld part of the cradle to act as a fuel tank for storing gasoline for the skiff. Again, the doubler plates will allow me to build the cradle later without destroying the paint outside or inside under the finished ceiling. The plans Im looking at for a skiff is 12 long, 5 beam, powered by 20 hp, and can carry 1000 lbs. It will weight about 300 lbs when completed.

The last roof job I need to complete is welding the tabernacle for the mast along with the pad eyes for the mast fore stay and shrouds, and brackets for flopper stopper poles. Flopper stopper poles are poles that extend away from the boat when at anchor and allow you to hang a device that helps mitigate rolling of the boat. I accepted some advice from an engineer I know and am reinforcing all of these parts to be robust enough to accept a more demanding paravane system to help with rolling while were under way. Because Im building a lot of these parts out of 1/2" stainless, I had to develop a cut list and have a local shop cut all the parts for me on a band saw. I just got all the parts back from the shop the other day, and Ill start putting it all together this week.

By the end of the week, Ill be able to move the welder off of the roof and finish a few simpler jobs on the aft wall of the salon. Primarily, the fill and vent points for the fuel tanks, the outdoor shower brackets, cutting the starboard side of the salon  so the boarding door works, and a few other smaller brackets. I feel pretty good that Ill be prepping for paint in a week or ten days, and should be done painting by mid September.. I might sneak away from work a few days to make sure I can get all this done, but early October looks to be about when Ill be moving her out.
