Portuguese bridge door and cap

Sunday, March 20, 2016


Ive completed some more finish work, mainly the Portuguese  bridge passage door and the wooden cap for the Portuguese bridge.












The Portuguese bridge door provides easy access to the fore deck while securing the bridge from any rough weather and  helping keep our feet dry. Because this door could see some green water, I thought it important to have a jamb the door will be in full contact with once its closed. Making the jamb out of wood seemed to be the easiest way to go for me.  I wanted the door to be able to handle any green water it might see without getting twisted, torn off, or damaged. I tend to make things up as I go along, and with no real plan, Im happy with how the door  turned out. I turned the door handle out of some 3/4" stainless round stock, and used a round over bit in the lathe to finish the ends. I also turned a stud with threads on the end to hold the handle in place, and make a pivot to engage the handle. Basically, the handle will dog down against the jamb, pulling the door tight and holding things fast. A nylock nut and washer holds the handle to the stud. To  make the keeper, I mortised out the wooden door jamb, then fabricated a stainless steel keeper for the handle to dog against. I gave the keeper a slight taper to help lock the handle in place. The more you engage the handle, the tighter it dogs the door down. As things wear and tolerances get looser, I have plenty of areas to adjust ( without much difficulty) to keep the door locking tightly. When were on passage, the door will be dogged shut. When were lounging on the fore deck, or working up there, the door will be opened and resting against the Portuguese bridge. I need to find a rubber bumper to hold the door off of the PB, and also to prevent paint from chipping if the door gets slammed open.


The other item I finished was adding a wooden cap to the Portuguese bridge. A lot of you are probably thinking that Im an idiot for adding some bright work, and I hear you, so let me spout off my justification. I like the look of bright work, and I dont mind the maintenance as long as its easy. The height of the wood cap and the fact that there are no rails or fixtures to work around will make this an easy area to maintain. Scuffing this cap with some 300 grit and apply some varnish, will be fast and easy with NO BENDING OVER on captain Conalls part. Im liking this part, and if I was on face book, Id give her a thumbs up. Because the Portuguese bridge area is going to be a pretty social spot, I wanted the wood cap to make things more comfortable, and give all a comfy  place to lean on and rest a beer. The wood cap feels and looks nice, and hopefully will eliminate bangs to any revelers funny bones.

I had to use the last of my wide boards to form the cap. I used the band saw and a belt sander to form the curves. I then used a 3/8" round over bit in my router to ease the edge of the cap. I ran out of wide boards so I ended up edge gluing some stock together to finish the job. I used a combination of traditional scarf joints reinforced with biscuits, and floating tenons to reinforce all the joints. Just before where the wheel house meets the salon, the Portuguese bridge terminates with a sever angle down to the deck. This leaves about thirty inches between the Portuguese bridge and the wall of the salon.  I treated this area of the cap by laying the cap over  the top of the cap headed down to the deck. I could have used a miter joint in this area, but I was afraid the joint would open up, and I like the way the eased edge of the top cap feels and looks. This is also the area where the spring line will be secured, and also where the shore power cords will pass through. There will be a two bar stainless steel rail bolted to the down cap and welded to the salon in this area, but that cant happen until the salon is in place.

  I bolted the cap down to the PB using 1/4" x 1 1/4" stainless screws and nylock nuts. I counter sunk and bunged the screw bore so no fasteners can be seen from the top of the cap. I had a few bad spots in the wood ( primarily a few dead branch knots) that I treated the same way I do all bad knots on my wood work. My preferred method of dealing with dead branch knots is to rout the bad wood away, and install a Dutchman patch. I use an inlay tool in my router to make these patches. The Dutchman patch is a legitimate repair used for centurys, and give the work that "homegrown, folk art character that I like. The cap will get four coats of urethane, then I will caulk the underside joint where the wood meets the metal. Once the caulk is laid down, this job will be off of the list.

There is really not much left to do to the fore deck and Portuguese bridge until the boat gets TO THE LAUNCH SITE , so Im going to scratch this area off of the list I keep meaning to write. Im kind of glad Im finished working up here,  as Im getting tired of ducking under the barn trusss . Ill vacuum and clean this area this week when I finish, and hang some tarps over it to keep the dust off and forget about it until shes out of the barn.

Wheel house door sheathing

Saturday, March 19, 2016

The boat yard has been closed for the last ten days, so yesterday was the first day Ive been back to boat in that amount of time. Ive left my camera at the boat, but I did remember to bring it home with me so heres an update.

The new year has rolled in here with some raw weather. A storm found us last night, and as I type this update this morning, the temperature outside is -1 F. The lows foretasted for next week are -15.

The wheel house door is aluminum, and instead of sheathing the wheelhouse side of the door with aluminum, I decided during building of the door, that I would sheath it in Cherry. This is a fairly straight forward door, but like all things engineered by the seat of ones pants, I have to build a little forgiveness into my designs. The biggest guess I had to make was how much of a gap to leave between the door stops and the door to accommodate a sealing gasket. For this purpose, I made the hardwood stops easy to be removed by installing threaded inserts into the door. The threaded inserts are installed by drilling a proper sized hole, then using a special tool to crimp the insert into the hole in the aluminum. This is almost identical to a rivet, but is extremely robust. I bedded the hardwood stops in silicone and used a 10-24 x 1.5" stainless pan head screw to fasten the stops. The screws are 12" on center.  The other alternative to fasten the stops to the jamb would have been to through bolt the stops in place, but if one ever have to remove a stop later down the road,  the casings would also have to be removed to access the nuts. Through bolting is also kind of sloppy in my opinion and alignment seems to be a fuzz more difficult when through bolting.

I sheathed the door with 1/2" Cherry  plywood. Because I did not want to see the edge of the plywood I turned to my tried and true method of ironing hardwood veneer. Ive been using this iron on edge banding for years now, and have never had any issue with the adhesive failing. Once you iron the edge on, you trim it off with a special tool that cuts both sides flush in one pass. A light sanding with 220 is all thats needed to make the edge perfect.   I love the edge banding system.

Im totally happy with how the door looks sheathed in cherry vs sheathed in aluminum, but I do have one issue Im going to have to deal with. The Trioving lockset fits good in the thick door, but the dead bolt trim does not work with the thickness created by the 1/2" ply. In order to make this work, Ill have to remove the sheathing, and cut square around the deadbolt, then brake a aluminum trim piece to hide the edge of the ply in this area, and re install the ply. I dont have a picture showing this issue, but the lock set is installed and working correctly although the dead bolt does not look as it should. 

The wheel house walls are almost finished being sheathed, and most of the window trim is installed. The stairwell ties in to the wheel house and salon sheathing and is burning up some time. Theres a lot of confabulated, ridiculous boat type detail in the stairwell area, but I should have it wrapped up next week.

After almost a two week absence from working on her, I can tell you it feels great to be back working on moving things forward.

Cheers

Passage door update 2

Wednesday, March 16, 2016






All five passage doors are hung in their openings and have two coats of urethane finish on them. Another fairly large job can be, for the most part, checked off of the list.

Because of having to build the boat in two sections ( hull/ wheel house @ salon), I cannot install the ceiling in the hallway and master cabin. Because I cannot finish the ceilings, there is no point in casing the doors, so that job will wait until the boat gets to the launch site.

I purchased a mortise lock set for the master cabin bathroom door. The lock set is solid brass with a brushed nickel finish so my hope is the lock set will handle corrosion. I installed the lock set and Im happy with how it looks and works. Installing a mortise lock set is a slow, time consuming job with very little room for error. I roughed in the mortise with a 5/8 forstner bit, then cleaned out the mortise with a chisel. I had to make a jig to hold the door plumb with my drill press, and other than cutting the mortise a 1/4" shallow, all went well. From start to finish, I had about 2 1/2 hours in installing the lock set with 1/2 of an hour consumed with building the jig for the drill press. The lock set has a dead bolt so we can lock the door from inside of our cabin. I think Ill have dead bolts on our cabin doors, and the bathroom doors, but will use lock sets without dead bolts for the other doors.

I brushed two coats of gloss urethane finish on the doors. Im not incredibly happy with the finish and I think Ill spray the final coat of finish on the doors. No matter how hard I try, I just cant seem to brush a good finish on my work. I think my problem is Im expecting too much out of two coats of finish. Next summer, when the boat is at the launch site and were putting the final finish coats on everything, Im hoping Ill get some help on getting a decent top coat on all the wood. For right now, everything is getting two coats for protection, and thats the story Im sticking with.

The next job is to get the bathroom completed. There is really not a huge amount of work left to finish that room, and I should be able to get it off of my list in a week or so. I have to install the exhaust fan, install the ceiling, fabricate the interior trim ring for the portlight, and install the portlight.

Salon passage door

Monday, March 14, 2016

There are two passage door on board, one in the salon and another in the wheel house. The salon door I decided to build out of wood, and the wheel house door will be aluminum. The salon passage door is on the aft deck, under the aft  deck roof and protected by the 36" solid steel bulwark that surrounds the aft deck. The wheel house door is a little more exposed given that its on the front of the boat. The free board on the at the wheel house door part of the boat is almost 8, and the wheel house is protected by a 46" tall steel Portuguese Bridge. The fore deck is also protected by a 36" tall solid steel bulwark.

The wooden salon passage door is what I would describe as robust. Because I am using Trioving mortised lock sets, and because I wanted a stout door I decided to  build the door 2" thick. The panel for the door is 3/4" plywood. The door is built out of Cherry.

I did not have any 2" thick cherry stock so I had to laminate three pieces together to get my 2" thickness. I like to laminate material using a form, and welding a couple of 4" H beams together made for a nice straight form that was easy to clamp to. By using a "straight as string" form, my laminations came off of the form perfectly straight.

In my opinion, mortise and tenon joinery is best for a door such as this. The first step in joining the door together after I had all the stock prepped was to plow the groove for the panel. I used a stacked dado cutter in the table say to plow a 3/4" x 3/4" groove stopping short of style ends by 1". I finished the panel dado with a cutter set up in my mill. I then used the same cutter in the mill to cut the mortises to their 2 1/4" depth. The mill is really a nice way to cut these deep mortises.
 







The tenons were cut using the same stack dado cutter in the table saw. Because of the amount of time to laminate the stock I was very cautious cutting the tenons and left them about .030 over sized, and  then used a chisel and sand paper to bring them to the final thickness. The fit I was looking for was for hand pressure only to drive the parts together. A slight interference fit with  not mallet needed. There is such a thing as too tight. Dry fitting the parts together found no problems. Once the door was glued, clamped and squared, I through pinned the mortises using 3/8" walnut dowels. The Cherry has plenty of character and is for sure nice to look at, but the walnut pegs add a wee bit more interest to the door.

The mortise for the Trioving lock set was cut on the mill using a 1 3/8 forstener bit.  Ill go in to the lock sets a little more in the next post, but I will say that I found the lock sets used on Ebay two years ago. If any one knows anything about Trioving, you probably know its high priced stuff. I had to take one lock set apart to test fit it in the door, and I was impressed by the high quality of the parts, and the fact that its all easy to service and re build-able.  Nice equipment.

I sanded the door to 220 grit and coated with three coats of urethane. The next step will be to mortise the stainless steel  hinges, build the jambs, and devise the gasket. I feel pretty confident I can make the door weather tight and able to handle some water getting on to the aft deck. I think Im going to fabricate two dogs for it similar to how I dealt with the bulwark doors.

Wheel house door

I built the wheel house door out of Aluminum. Given how exposed the wheel house is, I thought Aluminum would offer me a more tough door. Now that its all said and done, I do think the aluminum door is more robust than my wooden salon door. The salon door, at two inches thick is for sure a tough door, but the all welded Aluminum door appears to be pretty tough given the weight of it.

The first decision I had to make on the wheel house door build was how to build the frame.  I found a piece of 2 x 6 x 1/4 " angle at the scrap yard and ripped the six inch side to 4" to match my 4" wheel house frame depth. The angles on the rough opening are a degree off of 90, so a little fitting had to be done before I could tack the frame together. I guess at this point I should say that I TIG welded the wheel house door. The frame was assembled using miters, with all the cuts being made with my miter saw... you gotta love Aluminum. Once the frame was fit in to the opening, I built the actual door frame using some 1" x 2" angle and some 2" flat bar for internal framing. I had the hinges in the shop, so figuring out the reveal of the door was not too big of a deal. With hindsight being 20/20, I wish I had used a hinge that did not require a mortise. I ended up having to create a  mortise for the hinge in the door, and while not  a deal killer for the success of the job, it was sort of a pain.

The flat bar cross member framing of the door was laid out for a couple of strategic reasons. Two of the cross members were laid out as to house the Trioving lock assembly. To make all the lock assembly housing hidden yet removable, I added an internal plate to bolt the lock assembly in to. Trioving bores four holes through this composite lock assembly housing for just the purpose I needed. The four bores are the same size needed to tap a 1/4-20 thread so one can attach the lock housing assembly to the door. On my wooden salon door, I created a mortise, then epoxied the lock assembly housing in to the mortise. The other two flat bar cross members were installed in the locations where my inside door dogs will be bolted to the interior door skin. In order to keep the door skin flat, I had to weld a few braces in to the door frame perpendicular to the cross members.

Aluminum is great material to work with, but controlling movement due to the immense heat created by TIG welding is a challenge. Taking your time and paying attention to the  heat is crucial. I also found that by clamping blocks of heavy stainless steel under my welds and along side of weld areas helped the heat sink in to the blocks and keep things under control. My external door skin was .090.

Because I had always intended on painting the door, I ground all the welds on the exterior of the door and on the frame. Once I had the welds ground flush, and repaired a few welds that failed as a result of grinding, I sand blasted the door and frame. On As per advice from my paint vendor, I conditioned the aluminum with some material I applied with a spray bottle.  The conditioner had to sit on the metal for 15 or 20  minutes, then I hosed the metal clean and let it drip dry. My paint guy said the conditioner is good for 24 for hours, so after baking in the sun for a few hours, I hung the door from some lines and gave it two coats of epoxy primer along with the frame. After priming the door, I faired the ground edge of the door first using West epoxy mixed with fairing compound, then finished with Rage filler sanded to 320 grit. Spot painting two coats of primer on the filler to seal it, then three or four coats of acrylic urethane top coat and the door was ready for assembly.

I pre drilled the frame for 1/4" screws, and will not final install the door until the super structure is landed at the launch site later this summer. I also have only installed a temporary stop as Im still undecided on what type of gasket I"m going to use to seal the door to the stop. Once I decide on the type of gasket and how much room the gasket requires, Ill bolt the door stop to the frame. The door stop will be  hardwood and will extend out the the edge of the door frame to also catch the interior  finish wall sheathing. Another important build part of my wheel house door is that I decided that the interior skin of the door will be Cherry to match the wheel house finish wood. Because the doors interior skin will be plywood, I bolted firing to the cross members.

After I land the super structure to the hull and have all he weld zones painted, Im going to have the spray foam insulators back to spray all those areas. When the spray contractor is on site, Im going to have him spray foam the inside of the door before I install the plywood interior skin.

Now that the wheel house door is complete along with the salon door, the last piece of being able to secure the boat from weather and other undesirables  is  now complete. Ive pretty much stopped working on finish type things of the build, and am now focusing on getting things ready to move her out of the barn. Getting her in the water next Spring is the plan, and believe it or not, that date is fast approaching. Its time to it done.

I started to add some You tube videos if anyones interested. The videos are pretty lame, but hopefully Ill start improving on them. Ill post a link soon.

Salon passage door completion

Monday, February 8, 2016

Im calling the salon passage door a wrap and the little work that needs to be done to it will be finished once its hung for good in its opening. I did hang it to work out some of the details and to make sure the lock set had no issues. The door is temporarily hung, and will be removed for the trip to the launch site just like all the other case work Ive done in the super structure.


Once the stainless hinges were in the shop I built a jig to route the mortises . The jig assures perfect alignment between of the  hinges between the door and the door jamb. The jig is just 1/2 plywood with the hinge layout cut in the jig a  1/6" of an inch larger the the hinge itself. The router is fitted with a guide bushing and a 1/2" mortising bit.

The door jambs were cut 1/8" wider than the opening. Experience has taught me the having the door jambs a bit proud of the finished wall surfaces make casing the door much more trouble free. Because the aft wall is only two inches thick, I decided to make the stop the door closes against the full width of the jamb. I also made the stop a full 3/4" thick vs the 5/8 one would normally see on a door  in a house. The door stop now is the full width of the jamb so the casing will cover the joint  between the  jamb and the stop. I might regret this one day, but I glued and nailed the stop to the jamb, and once its permanently hung in the opening I"ll add screws to the stop. A few of the screws will be thru bolted to the metal frames as will some of the hinge screws and the stainless keeper that the lock set lands in to.

One of the reasons I hung the door was to see how the door  seal gasket was going to work out. I purchased a 3/8 round hollow rubber gasket with a 3/4" spline on it. My intent was to  cut a rabbet in the stop for the spline to lay in, and have the 3/8" round hollow  bulb act as the seal getting compressed when the door closed against the stop. Fitting this idea up proved to be a problem, and after a day of tinkering with it, I decided to used a closed cell gasket. I had some 1/8 and 1/4 x 3/4 closed cell foam in the shop and was able to position the stop so that the 1/8 material would work and create a nice seal. Watching the door close on my mocked  up pieces had all looking good and Im happy it looks like that idea will work out OK.


Before I was able to call the door a finished  job, I wanted to make sure the Trioving lock set was going to work given the thicker stops I installed. Ive seen situations before where full mortised lock sets have the  handles hitting the stop as the door opens. Trioving uses a very deep mortise for the lock set @ 4 1/4" so this scenario really wasnt a problem. Trioving has some pretty nice user friendly design in their gear. The screws they use to hold the sets together are machined to adjust. Once you have the lock set in place, you cut the screws in a machined groove they  have to get the proper length. This way one does not have to use a die to repair the cut end. Another nice detail Trioving uses is how they hold he handles on to the square stock that passes through the lock set. The square stock is split in half for a certain distance where the handle lands, and the set screw that holds the handle in place is extra  long. The  extra long set screw has a long nipple machined on the end of it and as you tighten the set screw in place,  it engages the slot in the square stock and spreads it out creating an interference fit between the square stock and the handle. This is a much nicer way in my opinion to retain the  handle vs a set screw that just engages the stock.

I purchased the Trioving lock sets off of Ebay used, and the keepers that mortise in to the door jamb did not come with the lock sets. I used some scrap 3/16  316 stainless I have in the barn to fabricate the keeper. I used the  mill to  machine the slots that the two lock set bolts will engage. The bolts are 1/2" wide, so I machined the slots to 9/16". Once the door is hung for good at the launch site, and after the seal is in place, Ill adjust the keeper in the jamb and final grind the slots depending on how tight I want the door to  close.  I might have to TIG weld a small return piece of stock on the slot that engages the handle bolt, but Ill figure that out once the door is permanently hung. I I also might try to broach square corners in the keeper, but once again, well see how it fits.
 

Now that the salon passage door is complete, Im thinking of turning my attentions to the wheel house aluminum door. I was thinking of making it a dutch style, but given how tall my bulwark is, I"m not so sure I n need to do that. I have pretty good ventilation in the wheelhouse, and if Im in a situation where I need to have the door closed, 100% closed vs 50% closed with a dutch door is not going to make any difference regarding ventilation. The dutch door seems to be  more appropriate for boats without the bulwark, and also adds some complexity to the fabricating. Im still up in the air on that decision so well see.

Cheers
