Whitehills Lifeboat by Gribeauval
« on: February 25, 2008, 11:20:18 PM »

As I said in my RTR tug rebuild I have been researching/building a 1/12th scale model of a 35'6" Self Righting Motor Lifeboat for a gentleman in Whitehills, Scotland, who is converting the old RNLI station to a house. The boat was the 'RNLB Civil Service No4' built in 1932 by J.S.White's at a cost of 3,342, powered by a 35 bhp Weyburn AE6 petrol engine and was stationed in Whithills from 1932-48. After being sold out of sevice in 1948 it was last heard of in 1970 being used as a private yatch in Newfoundland.

After a great deal of searching a profile/deck plan was found and rescaled to 1/12th. Half patterns for the hull sections were made and then transfered to the ply ready for cutting. The keel section was made from three layers of ply as this class of boat had a drop keel which was used when under sail.

When the 'keel sandwich' glue had set, the keel and bulkheads were set up on the building jig to ensure that there would be no warping until the planking could be added. The bevel gears for the steering gear were alsao added at this stage as the shafts will be 'buried' after planking.

Steering gear in close up and the shaft support built and fastened in place.

Next phase was to add the decking as it is easier to do now than when the hul planking gets in the way! The caulking between the planks is chocolate brown paper strips glued between the planks.

After the decking the first layer of hull planking was applied. On real lifeboats of this period both layers of planking would have been diagonally laid. I have laid the first layer fore and aft as this allows for corrections to the shape to be made when I make cock ups!
The planks were steamed/soaked before gluing and pinning in place.The ends of the hull were not planked as the curves were easier to produce in solid balsa for this lower layer.

The end air box casings were also planked over at this stage and the hull planking completed.

Now the ends were filled with blocks of balsa and when set shaped and sanded to match the rest of the planking.

On the original boats the two layers of planks were separated by a layer of calico cloth. This helped with sealing the hull and still allowed a small degree of lexibility. This I reproduced with a layer of cotton sheeting (don't tell the wife!!) glued onto the planking. Even though it will never be seen again, I know its there, and that's all that matters. ;) When this was dry the outer layer of planks was fitted by steaming/bending and gluing in place.

After sanding the hull the bilge keels were plotted,laminated and fitted in place. The hull then was given a couple of coats of sanding sealer ready to start the priming/painting.

After several applications of sanding sealer and much rubbing down three coats of primer were applied. After flattinmg down and allowing to harden two top coats were added of blue and white.

Whilst waiting for the paint coats to dry I started on some other parts of the boat. First the rudder and then the navigation lights  on the small foremast. For these I used led's.

Next major problem was the small deck shelter. This curves in two directions, each plank is different  and was a pain in the butt to do!
The solution was to shape a block of florist foam and use that as a former. The foam had a couple of layers of papier mache to give the inside a smooth finish. A layer of mahogany veneer was then glued in place and, when dry, sanded down smooth. Next the outer frame was added and then the top layer of 1.5mm mahogany planks were steamed, bent, fitted in place, sanded and varnished. Finally it was trimmed to size and the port holes added.

Next piece of mahogany to be built was the engine casing. It is simply a box with hatches on the top to allow access to the single Weyburn engine just in front of the shelter. The engine has remote controls fitted in the shelter.

Moving towards the bow, the casing over the drop keel was constructed as well as the tabernacle for the mast. the mast itself was tapered and the heel squared off to fit. The signal light on the top of the mast was also fitted and power to the led is by thin solid copper wires glued to each side.

Next to be tackled are the air cases/side benches. The forward sections are made from beech blocks with lime sheeting for the tops. At the bow end of the port seats is a locker for the anchor cable. When painted lime slats were glued on top. At the stern the benches are fitted around the stern towing bitts.

Now the up to date part of the build.

The fittings for the sails/shrouds at the mast head have been started, (using the excellent fittings from Redbank Models, no connection just a satisfied customer!) as to allow the mast to fold down all the rigging of the gaff rig has to work correctly.

The major work on the standing rigging has now been finished and by the kindness of my wife the two sails have been made.

The sails have now been fitted in place on the boat. Now that this stage has been reached I now have to remove all the rigging in order that the minor fittings and painting etc can be added!! Typical of life! Two paces forward and one back!  :(

Started on the smaller fittings now.
The anchor is a slimmed down fisherman's pattern anchor (Model Slipways), I used a 1/16th scale one as this gives the correct size for this lifeboat at 1/12th.  ???

I also found a working compass at the local Pound Shop (built into a key ring!) that was the correct side and it is fitted into a painted brass case ready to hang inside the deck shelter where it could be seen by the helmsman. The life rings are made as I usually do, curtain rings of the required size.

Also work has started on fitting out the deck shelter. The flooring is made from hard plastic tapestry canvas with the correct hole size, much easier than trying to build the things from scratch! The spaces are where the lockers will fit. The console at the end is the engine /gearbox controls so that the mechanic doesn't have to open the engine cover hatches in foul  weather and risk swamping the engine.

Just finished the main fitting out of the deck shelter with the other two lockers and have added the binacle made earlier.

You really need a little brass wheel in there instead of that red plastic one  ;)

The curtain , sorry LIFE rings have now had their support frames made and fitted either side of the wheel on the rear bulkhead. The rings fit tightly (not glued!) on to the hooks and are ready to throw to persons overboard.  8) The last picture shows the stanchions/chains fitted on the gunwale and the new red colour of the sails as before they were too light for my liking.
