Boat Plans Wooden | Power Steering

Boat Plans Wooden



Im working on the power steering but really dont have much to post in terms of pictures. Most of the work right now revolves around routing the hydraulic lines, drilling holes, and mounting all of the bulkhead fittings. All the lines have been routed and are in the back of my truck ready for a trip to the hydraulic shop where Chuck will smash the ends on.

My hydraulic steering system is basically a power steering system. I have a pump that is driven off of a gear that runs off of the timing gear on the engine. I have a six gallon reservoir for the hydraulic fluid and a filter in the return line. The engine mounted pump drives my helm pump which is what the steering wheel bolts too via a 3/4" tapered, keyed shaft. The helm pump then sends fluid to a dual ram steering quadrant that turns the rudder. This is a pretty simple system that is what I would call robust, and should give me decades of trouble free service.

Im still waiting on the pump drive adapter from Deere, but that should be in this week and Ill then be able to finalize the installation and start posting some pictures.

Heres another diagram showing how the auto pilot solenoid valve will plumb in to the circuit.

Kayak Boat Plans | Weather tight for the most part

Kayak Boat Plans


Im going to need to get back to work to get some rest. The last couple of days have found me dodging my paying work obligations in order finish welding the super structure to the hull and making her weather tight. Dealing with the heavy dew forces one to finish certain jobs in the afternoon or deal with repairing some rust damage the next day from the dew.

When we landed the super structure to the hull, the initial fit of the structure just sitting there at first glance could have been better. My friend Ollie, whos helping me fit out the boat, was a  little freaked out and later told me he figured wed have two or three days in getting the structure to fit. Because Im working off of plans, and CNC cut parts, as long as the super structure itself fits together, there is no other outcome available but to have it fit to the hull. When building the super structure, if I had deviated from the plans, and had cut on the parts of the super structure, it probably would not have fit the hull without major modifications.

With the superstructure just sitting on the hull, we had a 2" gap where the forward wheel house wall hits the deck, a 0" to 3" gap where the port side wall lands on the salon hull flange, and the whole thing had to be pulled back more than an inch. We had one corner, starboard,  where the salon wall turns 45 degrees to head aft that was pretty close to the mark... here is where we started the fit up. Welding a cleat to the deck, and using a ratchet puller, we pulled the structure about 1/4" to hit a mark, and tacked it. After a few tries, we finally found the right angle and location for a welded cleat to pull the salon wall forward to land on the 45 degree 8" long wall,  and laid in some heavy tacks. Those two seemingly insignificant  pulls un-twisted some of the salon, and we now found part of the wheel house starboard wall firmly on the fore deck vs the two inch gap we had only 2 hours ago. Now that the wheel hose was down on the deck, we  used the Port-A-Power to push the wheel house over to locating points and tacked it down. All the CNC parts had lay out lines etched in them upon arrival from the cut shop. Before I had painted the wheel house deck, I had drilled dimples about every two feet on the  layout lines so I could locate the wheel house layout lines through the paint when the time came. Being able to locate a part is critical and having referenced locating points saved the day. With the starboard side of the wheel house now tacked down and in its exact position, we moved to the salon and began pulling the wall to meet the flange joint at each frame. After we had the wall tacked on the frame joints, we moved between each frame, and pushed the flange up to meet the wall, then tacked.  Moving over to the port side, we used the Port-A-Power to push the whole structure back, and were feeling pretty good as it just about fell in to place. Having the starboard side right on the money was forcing the port side  in to  place. Once we had both port and starboard side tacked in to place, we then worked on the end walls, which was just a matter of making sure they were straight with no bows or bellies, and tacked them down. Getting the super structure fitted in to place, and tacked welded, took the two of us about eight hours.

Finish welding the structure to hull joint took a long 12 hours with two welders running. Because of being outside, and not wanting to deal with moving the MIG welder around, I decided to stick weld the job. We used a Miller Bobcat, and an Everlast inverter based multi process machine running off of an 8000 watt generator to get the job done. Stitch welding using 2" welds, and moving around a lot was the schedule. I had spray foamed the inside of the hull prior to all this work, so we had to be careful about catching the foam on fire. The foam is fire rated, and it for sure lived up to that description. Keeping  an eye on the foam with plenty of  fire extinguishers ready was about all we had to do as it self extinguished once the heat was taken away. 


Once the welding was complete, we knocked off the slag, ground the welds for fairing, and brushed two coats of epoxy primer. The boat yard does not allow any spraying of paint.  Before the weather gets real ugly, Im going to get some fairing compound on the welds to finish the joint and give it two more coats of primer. This is all Im going to do until next Spring in regards to painting the outside.

On both the port and starboard side, we burned off about two feet of hull paint where the salon wall ties in to the hull. This will have to be faired and blended back in to the green hull next spring.

The only paint patching I have to do is on the aft deck of the salon. Weve had two days of steady rain,  and this is the only area we did not get primed. Once the rain stops, Ill finish priming this area and scuff and prime the weld zone inside the super structure. Once all thats finished, I have to bolt some lumber to a few short frames, then patch in the foam.

The decks have been blasted, two coats of primer and three coats of acrylic urethane before we moved her outside. I had all along planned on re painting the decks, and after the beating they took on welding the super structure, they for sure will need painting before launch. There is also a lot of soot on the side walls from the stick welding that is going to  have to be washed off. The whole boat is nasty dirty, and once I have the paint patch to a point Im happy with, I might take a day and give her a bath. 

Im going to have to get back to work this week coming, although this monsoon we just had will probably rain me out half of the week. This flurry of boat building has me feeling a bit tired, but a happy tired as were getting things done in big gulps.

Cheers

Boat Plans Uk | Water tight doors

Boat Plans Uk





While waiting for parts for the steering system I decided to install the water tight doors in the engine room. As my son would say, " everything tight doors" is really a better description.

The doors have been laying around the shop ever since I bought them at the start of the build. I welded the frames in to the bulkheads, then forgot about the doors. The door leading into the engine room from our cabin is a six dog quick acting door with a port light. Since I dont need the aluminum dead light that came with the door, I took it off. The port light glass in this door is 1/2" thick tempered, and the door itself is 1/4" thick. This door is what I would call severe duty, and is both water tight and fire tight. When this door shuts, things are pretty much final, and no air or water is getting past it.

The door leading from the engine room to the lazarette is a four dog door that is not quick acting. It too, has a port light and is also 1/4" thick. Since this door has no adjustments, the new gasket and dogs are still tight, and I have to use a rubber dead blow mallet to close the dogs. I dont have to hit the dogs to hard, but the mallet works better than my hand. Ill end up buying a dedicated mallet, and hang it on a hook next to the door.

Both doors have a bronze port light in them, and we decide to polish the port light. I had some stainless steel pickling paste in the shop, and brushing some of that on the bronze took the tarnish right off. It was almost too easy and looked like one of those Billy Mays commercials except for the fact that pickling paste is nasty stuff and will give one a good burning if youre not careful. After the acid treatment, I gave them a good scrubbing in cold water, the put a paste wax finish on them to try to keep the tarnish at bay. Well see how this works out.

Both the AC and DC light switch for the engine room is in our cabin so I can see in to the engine room through the port light without opening the door. I felt like this was important in case something was going on in that room I wanted to see and still maintain the integrity of water and fire tight. It also makes it easy to do a quick check without letting the noise and heat in to the cabin. The light switch for the lazarette is outside the lazarette, in the engine room, for the same purpose of being able to look in without opening the door.

I think Im going to fit some mineral wool insulation in the quick acting door from our cabin. The engine room is heavily insulated, and the door is really the weak link in the insulating chain. Id guess an inch of insulation will knock the noise that will be hitting the door down by 80%.

An update on the fuel system is also needed. I had to re think the priming pump as the chevy pump I had on my shelf was not up to the lift out of the day tank. I found a new Walbro pump on Ebay for not much money, and got it installed. Walbro is a top of the line pump and with just three moving parts, this pump should last the life of the boat. Ill only use this pump to prime either the generator or main engine after I service the filters or for an emergency such as an engine loosing prime, or one of the engines loosing its factory mounted lift pump. This pump is rated at continuous duty, so if one of the factory mounted lift pumps fail, I can always rely upon he Walbro as a good back up. Once I got the pump installed and fired up, it quickly picked up the fuel and filled my filter. I opened the valve leading to the generator, and got fuel flowing to the fuel pump. Just for kicks, I cracked one of the injectors, and had fuel spitting out of the injector. That engine is primed and ready to fire. I might use some street 90s for connecting the pump to the valves, and do away with the loops you see and make things more streamlined.

Im still putting pieces together for the steering system, and should be working on that within a week or so.
