Chrome Parts

     

                                                   Chrome Parts

Since I do want to bring the Boat back to original as possible it was decided to have all parts brought back to their original chrome status.  It took some time to find a company who can perform the old fashioned trade of treating parts with chrome. There are several companies on the marked which will do a chrome job but are not able to perform the complete required treatment of treating parts with chrome, important steps for a proper job are missed. Next you will find a link how it should be done in my opinion.

One thing to be taken in consideration of have parts be treated with chrome is the price since a good reliable treatment of parts is not cheap compared to new stainless steel parts.

But in my case I want to bring the boat back to an original condition and the same type of parts cannot be obtained in stainless steel.

As can be seen from the following pictures there is a definite difference of before and after and although in some cases buying news stainless steel parts might be cheaper it will never look the same as chrome parts.

In The Netherlands I have found the following company, www.verchromen.nl , who perform the proper task of reconditioning the chrome parts of the boat, of which several were painted with silver paint.

Replacement of the deck of the bow

December 2011

                                                              Replacement of the deck of the bow.

After installing the longitudinal deck beams under the deck the complete deck of the bow needed as well to be replaced. This included all the deck supports, support for the escape hatch as well as other needed supports for deck equipment. This replacement will be done in two steps first step is to remove the old deck and replace the needed deck supports with a new marine 6 mm plywood deck.

Second step will be the installation of a new teak deck.

A start was made by removing a  part of the deck, we did not want to remove the complete deck at once since the installed new longitudinal deck supports needed final shaping with the transversal deck beams. The first part of the deck which was removed was between the actual bow and the forward bulkhead, this included two deck supports.

By removing the complete deck not at once but in parts we could keep a reference between the old installed deck and the new to be installed deck. After installing the first deck supports we had a reference  between the old deck and the new installed deck supports preventing that the new to be installed deck would be in a different position, higher or lower, than the original installed deck.

 The new deck supports were made from pine and were shaped according the old removed supports, this was done one by one by more or less a copy paste of the old removed deck support. They were kept longer at the ends than the original ones and shaped to the correct length when installed. The reason that they were kept longer than the original ones has to do with the fact that also new longitudinal deck  were installed which could be in a different position from each other compared to the removed ones. After temporarily installation of the deck supports it was checked if they were not installed to high, with the old deck still in place we were therefore able to check the correct height.

To have guidance for the installation of the new deck supports a small piece of wood was installed under the original deck supports before they were removed, see also the following picture.

This support was a guide for the installation of the new deck supports and was not removed until all new deck supports were fitted in place. The deck supports were fitted in the same way as original built under an angle in the longitudinal deck beams and screwed in place, the only difference to the original installation is that we glued them in place with epoxy as well.

The last deck supports which runs on the inside of the cabin from port to starboard side needed to be made before the actually new deck could be installed, since we do not want to remove the complete deckhouse yet. This was the one in the forward cabin which is round and which has the same curve as the rest of the deck from centerline to portside and starboard side to be able to let the water run of the deck. This round deck support was laminated from marine plywood strips which were glued together with two component epoxy. To get the same shape as the original one the old deck support was cut out in one piece as much as possible and the new strips of plywood were glued one by one against this old deck support to get the same curve and shape.

After all the deck supports were installed a check was made with strips of plywood to check if the roundness of the bow was correct,  it was checked if none of the deck supports were higher or lower than the two next to it. After some minor changes and checking the complete deck supports from aft to forward it shows that all was installed as best as one could expect.

To make sure that ports side and starboard side deck beams are on the same height measurement were taken from one point of the center keel line to port and starboard, otherwise it can happen that one side of the ship is higher than the other side.

When all deck supports were fitted in their final position the support for the escape hatch was installed as well as the supports for the deck boulders. The support for the escape hatch was made from two layers of 10 mm marine plywood glued together and screwed in place on 3 deck beams. After installation it was shaped in the same curve as the deck beams where it is placed into. The actual hole for the escape hatch will be made after the teak is in place this will also result in that the deck support in the middle of the escape hatch will be cut out, this cannot be done at this moment since it provides strength for the installation of the to be installed teak deck. The supports for the deck boulders were made from oak as original.

The deck is made from 6 mm marine plywood like original, to make my life easier I have painted the inside deck white before it was installed, two layers of epoxy, the thin type with white pigment and one layer of normal white paint. This will have as a result that I have only to do some touch ups instead of painting the complete deck from inside which is time consuming.  Also the deck supports have been sanded and put in a protective layer of epoxy. Before installing this prepared 6 mm under deck the white paint/epoxy has to be removed at the position where it will be glued onto the deck supports and longitudinal beams.

The new deck was glued with epoxy on the new deck supports and screwed temporary into the deck supports for good contact.  The excess of glue was directly removed from the inside to avoid long and difficult work in a later stage by removing cured glue/epoxy. After the complete deck was installed the screw were removed,  holes filled and the completed deck was placed in a thin layer of epoxy as a protection for the winter , the next step will be completing the complete marine plywood deck around the deck house before new teak can be installed. This will have to wait till next year, 2012, since the humidity and temperature prevents that epoxy glue can be used.

Replacement of Longitudinal Deck Beams

The below update of October 2nd 2011is also added to the original firts blog to make it a continues story, it can be read under Older Posts, Firts Inspection Storebro 34

                                               Replacement of the Longitudinal Deck Beams

The Deck beams running forward to aft under the deck and against the hull consist of two parts. The aft part till approximately the  forward part of the deck house are made from Pine,  the part of the deck beam running from the forward part of the deck house until the bow were made of laminated mahogany, thin strips, 10 mm, put together in the shape of the hull. The repairs/replacement of these laminated deck beams will be explained in the below text.  As with all till so far found under decks wood these deck beams were rotten away and in some cases repairs was done which have not lasted that long even parts of the beams were missing near the bow.  To make in our opinion a good repair both deck beams, portside and starboard side, were completely replaced. Instead of using mahogany planks it was decided to use marine plywood and of 9 mm thick, and glue these strips with epoxy together, this way creating a strong beams which at the same time , due to the epoxy, should remain water resistant. The choice for 9 mm thickness was made since these strips of wood can easily be bent in the correct shape required to fabricate new deck beams.

The first step was to remove the planks against the deck beam to find out how the original beam was constructed against the deck and against the hull.

The next step was to make a template of thick paper in the form of the too be built beam. This was done by placing the thick paper against the hull and then cut out the form of the too be built beam. After this paper model was finished a template was made of door skin, thin wood which was used as a template to cut the marine plywood which has been used to fabricate the beams. Although on the boat it looks like a straight line there is a curve in this beam as well as that the beam has a torque from aft to the bow.

Beams were made by placing the first strip of plywood against the hull to copy the roundness and bend of the bow. The next step was to glue each layer against each other. Every day one layer was installed to make sure that the epoxy glue had time to cure. Also it was needed to wait a day to remove the screws which were used to press each layer against the other one.

When the beams were finished, they were removed from the ship’s hull and the angle between the deck and the beam was transferred onto the new beam. Beams were temporary shaped with a sander, final shaping was done after the beams were installed and the actual deck beams were fitted between port and starboard, this subject will be explained in a later stage.

Old deck beams were removed from aft to forward and to prevent that the deck would fall down a support was placed on the actual deck beams running from port to starboard under-decks. This support is also needed for the correct position of the new deck beams under- decks.

After the deck beams were placed in the correct position, this is time consuming since a lot of measurements had to be taken to make sure that the deck beams are on the same height, ports side and starboard side above the keel. When we were satisfied with the new position of the longitudinal deck beams they were supported in place with some hull planks.

When they were fixed the rest of the bow planks could be finished, installing these last hull planks is also time consuming since the planks not only run from forward to aft but also from the keel to the deck, so there are two curves in the planks. After a few planks which took a long time to get a correct fit for several planks a paper template was made before the actual plank was cut and fitted in place.

The planks were screwed with brass screws against the new longitudinal deck beams and the frames. It was at the same time found that the most forward frames were rotten so new frames were made in place of the hull; this was done before the old frames were removed and before the old hull was removed.  Since there is quite a bend in these frames they were laminated from oak and glued together with epoxy.

Eventually the new bow is finished, just left were some plugs to be installed when this picture was taken.

The following project is to replace the deck, deck beams between the bow and the deck house.

Bow Replacement August 19 2011

A new part has been added as well to the original blog firts inspection to make it a complete story explaining how the bow was replaced

                                                              The Bow Replacement

Although I was aware that some of the hull planks under the deck connected to the bow needed replacement I was not really prepared to replace the complete bow, a so called nose job.

Earlier repairs had been done by removing planks of the hull which are connected to the deck and replace them with plywoodn due to rot.

The result was that, in my opinion a part of the strength of the construction was lost. Not only the hull planks were rotten away , but also the longitudinal deck beams running under decks were rotten and gone in several places. Especially where this beam is connected to the actual bow beam. Although new wood was added and rotten wood removed,  I have the impression  that the actual problem, water leakage from the deck down, was never addressed.

After removing all the rotten and bad wood from the hull as well as under decks of the actual bow the situation did not improve, more repairs were found, which in my opinion were not done professionally. The result of these further inspections resulted in that it was decided to remove the complete bow from deck to the keel.  Although this is not a difficult job it has to be well thought through. Luckily I have my neighbor who helps me more than regular and who often thinks outside the box. His solution was simple: cut the complete bow out and just built a new one. So we did .

The actual bow beam consist of 3 pieces one center piece from top to bottom and two side pieces, these three  pieces are hold together with long screws and threaded bolts. The next step was to find oak beams from which the new bow had to be built and shaped. To prevent a lot of cracking and distortion of the new bow I have bought old used oak which normally will not move or crack anymore. The next step is simple just copy paste the old on the new.  To do this a lot of measurements were taken as well as shapes on different positions of the old beam which were transferred to the new beam.

When all measurement were transferred from the old bow beam to the new to be built bow the actual work started with cutting out the wood of a square beam and shaping this piece of wood into a new beam.

When the new beam was shaped and several times checked against the old one it was time to install the new beam, we must have done it right since the moment we placed the new beam against the ship it fitted exactly in the correct place no changes had to be made. The height was correct and even it ended up in the center of the deck. The beam was now placed in position with threaded bolts , connection between the inner bow beam and the new bow beam, and positioned at the top in the center of the deck and temporarily hold in this position  with some screws.

With the bow in place the next step was to install new hull planks, although this sounds simple it is far more difficult than replacing the hull planks from the aft side as was done in an earlier stage. The challenge is that the planks from the bow do have a different form than from the stern. They do not only bend from aft to forward but also bend from the keel to the deck as well as they are tapered from the  stern to the bow. The first plank at the keel was not to difficult but the next one had to much torsion that after three attempts it was decided to make this piece out of a laminated piece of wood. From there on it was just placing plank after plank one left one right to keep the bow beam in place.

Than the point is reached where the last plank reaches the top of the bow, at this point the new longitudinal deck beams have to be installed before more bow planks can be inserted.

The Planks were screwed against the beam and glued/sealed with Sikaflex Glue and Seal, this to create a flexibla seal between two different materials mahogony and oak. The planks were not glued with an epoxy glue or any other type of glue. This is the is done in the same way as original built.

The fabrication and installation of the replacement of the longitudinal deck beams will be another subject at the same time the finishing of the hull planks against the bow beam will be further explained.
