Time to keep Neil happy and post one of my builds on here. This one comes about as I can't yet get to my main workspace which is occupied by a 47ft Watson awaiting collection/delivery to Northern Ireland.
I have been following the restoration of the Twin Screw Liverpool class Lifeboat, George Elmy, on Youtube and having a pdf file of the GA drawings of this boat as well as some other section drawings of a Liverpool I decided to build one at 1/6th scale not the usual 1/12th scale.
The main drawing was printed out at at 1/6th scale on my A3 printer and joined to produce a single sheet. This is now too big to handle so was stuck on the only wall capable of holding it in the house, the main bedroom!! (Good job I have an understanding wife who after 40 years has learned to live in a boatyard!!!!)





The opposite wall now holds the other section drawings of the boat.





As I said earlier I can't work on large boats at the moment so I have decided to do part of the boat that can be done/moved around easily, the engine shelter/casing. This is double diagonally planked in the same way as the hull and at 1/6th scale can be built in the prototypical manner with frames and stringers under the planks.
The first step was to make the base frame. This was steamed, laminated and bent to shape over a full size template and allowed to set overnight.





The main strongback was steam bent to shape over a former and again allowed to set overnight.





A set of formers taken from the drawings were set up at the correct locations and the main strongback let into them (but not glued as the formers will be removed later) and glued to the base frame. Further stringers will be added and the main plank support hoops added next.

After a pleasant weekend at the Blackpool model boat show with like minded lifeboat lunatics, you know who you are !!, it's back to the building.
The rest of the main stringers have been steamed, bent and laminated in position.





The twenty support hoops for the planking are now under way. These also have to be steamed to persuade them to shape without cracking and fixed with the correct lean towards the bow.





View of the whole thing as it is today.





more when the rest of the hoops have been fitted in a few days or so.

After much more steaming and bending over the past week the last of the support hoops is in place and the glue hardening!







The spaces between the hoops have been filled with timber sections to bring the internal stringers up to the level of the hoops to give a level surface, after a touch of sanding, for the planking.




I have also started fitting the support blocks that sit under the deadlights/portholes on the canopy.

All the pads for the portholes have now been fitted and the structure sanded to fair in all the corners and edges to give a smooth surface for the planking.




The large portholes have also been started by soldering the protective bars onto the outside faces.These will be fitted after the planking and varnishing is completed.




First layer of planking next!!

Just what the others said Mike absolutely lovely.

Do you use a steam box or do you have another ingenious method of soaking the timber in steam?

I use a steam wallpaper stripper and a section of 4" diameter plastic pipe to make the timber 'bendy'. It aint rocket science, I like things nice and simple, difficult and complicated, but simple!!!!!!

The planking of the first layer is now underway. All day and only four planks on, this will be a slow job as each plank has to be steamed, fitted and trimmed then allowed to cool and dry out in place before being fixed to the frame.




The portholes have now been made. The fixed ones are made from solid brass eyelets from a local rope and tarpaulin makers with brass bars soldered in place. The glazing is done by fixing the finished item to a sheet of cling film covered glass with plasticine and using clear setting epoxy resin.




The two opening scuttles on the canopy are made using the same eyelets as the fixed ones for the base and the opening section made from several diameters of eyelets and brass washers soldered together. Just need to make the locking part now!

After much steaming and cursing the planking of the first layer is complete!!!!!
This has now been sanded and filler applied where needed to "improve" the shape on the lower corners.




The rear of the canopy has also been trimmed to the curve of the full size version.




The calico (in this case a cotton pillowcase) interlayer is now being fitted before the top layer of planks is added. This is held in place with a water based resin, normally used by aircraft modellers to skin wings with glass fibre tissue, which has no smell and sets in about 30mins .




This will be allowed to set for 24 hours before the top layer of planks is started.

I have to show my ignorance and ask, what is the purpose of the inter layer?

Now that the calico layer is fitted and the resin hardened the top layer of planking has commenced.
Each plank is now carefully fitted in place, taking care not to get glue on the top surface, and joggled into the king plank running down the centre line of the canopy.




As well as glue each plank will be nailed in place using small brass nails to simulate the copper ship nails that hold the two layers together. On the outer surface these are punched down and will be filled over when the varnishing is done. This will give the outer surface the 'spotty' appearance seen on the full size article. Inside the nails will be cut off flush with the timber to give the look of the metal roves against the dark timber.




See you when I get out of the jacket that has buttons up the back!!!!

Now there's a real joy working to that sort of standard. something to aspire to, but have to say the funny jackets usually put me off and short cuts look attractive.
