LIFEBOATS...my way
« on: October 31, 2007, 08:01:00 pm »

Perhaps this lot should have a seperate thread.
LIFEBOATS...my way.
I find that making these is about the trickiest and most awkward jobs on a model.
It is my preference to build wooden "clinker-built" boats as were fitted to older vessels. I also prefer to show them "open" (without covers). This is not a heresy. Many ships ran around without canvas or wood slab covers. Owners choice, I guess. As long as the bottom plugs were out the weather (wet, preferably) would keep the planks "tight". In tropical climes it was quite normal to see ships in port with their lifeboats lowered to the water still on the falls to allow water to creep in and swell the planks. I guess that if the crew had to abandon ship before they reached a harbour all the boats would fill with water. Odd thinking... However, leaving the boats overside/overnight certainly tightened the planks. Unfortunately the weight of water in the boats meant they were too heavy to hoist back up again...guess which low-lifes had to bale them out so they could drain via the plug holes. Us cadets. But not all bad news, if a bit of notice was taken a lot of "how it was made" info, could be gathered.
I don't think that wooden lifeboats changed their shape all that much between 1900 and the 60's when GRP made an appearance, but if there were differences then maybe at modelling scale they would not be too evident.
Being generally "double-ended" makes the job of making them a lot easier than, say, flat sterned "cutters". "Havelock" has 4 double-ended boats and 2 cutters (of different sizes....yeucch).
Computers and printers really make the 1st steps easy.
The drawing I have posted is almost certainly the wrong size for you..as it is for me. But by re-scaling on the printer (as opposed to "re-sizing" on the computer) you can make it any size you wish and maintain the proportions...or change them if you want to.
I won't explain all that now as I am sure most of you know how, but if you are in trouble drop me a PM or e-mail. The boats I intend to build are 5.75" long.

First Steps.
Once you have the drawings scaled to your satisfaction and have printed at least 1 copy of all 3 drawings, make multiple copies of the Body Plan (at your scale).
I'm going to find writing this very difficult and will have to revert to photos as the building moves on. However, the 1st step is to make a sort of mould. I use Plasticard.
First pic. The marking out is self-evident. The centre "backbone" is cut a little short to allow the keel and false kelson to be fitted..thats the bit that looks like a "slot" in the pic. The "ends" of the backbone are filed down to a pointy end to make a false "bearding" line...the stem and sternposts will cover the join.
The use of multilple prints of the stations is now apparent. I stick the paper printouts on to thinner plasticard and cut around them. Cut to fit (allowing for the thickness of the keel) and stick to the base. Thats the basic mould. Enough for today.

Back to lifeboats.
Sorry, but I made a bit of a mistake yesterday. The main mould "backbone" is NOT the part that should be give a knife-edge. Hopefully the pic. of the simulated mould will make this clear. The combined keel and kelson is the main bit as it is both inside and outside of the completed boat. What I have called the stem and stern posts are false ones and will be inside the boat. The same applies to the "filler" pieces which are "interior" and simulate (poorly) full size practise, but they cannot be seen on the completed model and add strength to the joints. In the past I have made the complete "backbone" in one piece but this has become too wasteful and expensive considering the cost of heavy Plasticard nowadays.
By the way, if you can scrounge (etc) some old "warning" notices or Estate Agents boards you will have a ready supply of heavy plasticard.
It may not have escaped your notice that both the mould and the boat are made of plasticard. So there is a 100% chance of the 2 items welding themselves together. I get over that problem by slathering the vulnerable surfaces with a petroleum jelly (Vaseline, sort of stuff). The mould I have illustrated has already had 12 boats taken off it so it works. Messy, but effective.
The next stage is to begin the planking.

Nice and cold today so I can work "indoors" and continue with the lifeboats.
As you will know I am building "Havelock" at 1:48 scale, so my measurements/dimensions suit that scale. The lifeboats will be roughly 5.75" long when completed. The keel/kelson,deadwoods and (false) interior stem and sternposts are fitted into the "greased" mould. I have decided to cut the planks to a width of 3/16" giving an overlap of 1/16" at the centre and reducing that by about 50% at the ends. The first 2 planks (garboards) are the most difficult as they can only be attached on the "thin" edge, apart from the ends, where a full width can be stuck. (All with Plasweld). Subsequent planks are a lot easier as the whole length can be stuck to the previous one. I don't bother shaping the planks. Part laziness and partly to give more structural strength at the ends of the boat. This will be seen later. As I am doing this job and writing about it as I go along I have thought of a little "mod" to the mould to make life a bit easier. Instead of holding the keel into the mould with my fingers, I think a little pin through the mould and the stem and sternposts will prevent the "boat" lifting off the mould as I plank it.  Done it. Works a treat. Should have thought of this ages ago!
Pics 2050 and 2051 show the planking being fitted over the mould. It looks a real mess, but a transformation will happen!

Very nice Bryan, and very effective in 1/48th. 

I'm not sure if I feel brave enough to try that with my steam coaster boats or whether I will take the cowards way out and line the fibreglass hulls with planks!

Another day and more planks fitted. The one in the foreground is the cleaned up mess in the previous post. The ribs are fitted as are the inner gunwale strakes. The teak veneer outer gunwale strakes are on. The cappings will be fitted tomorrow and I will begin to fit out the interior. Boat no.2 is progressing as I wait for the paint on no.1 to dry. Only 2 more hulls to make and then 2 cutters of different sizes to do, and thats the boats done. Says me...the fitting out and detail work takes ages. For the lifeboats I guess the planking per boat takes about an hour and a half, ribs per boat about an hour...waiting for paint to dry....?

Still plodding along with the 4 double-ended boats.

I have no idea why the pic did'nt come up..but it does if you click at the other line. Has Martin being playing around again?
In the pic (from left to right):-
1. This is the bare shell but with ribs, gunwhale veneer, inside gunwhale and capping fitted. Plus there is a small "rubbing strake" fitted below the veneer.
2. Breast hooks and bottom boards fitted.
3. Thwarts slotted in.
4. Side benches, thwart knees and lifting hooks in place.
It all needs a little "cleaning-up". Many items and fittings still need to be made and fitted but now the basics are done I can progress with the details that can make it all come to life (so to speak). Another 10 days or so.

Re. the "crutches", from a couple of e-mails I have rec'd. perhaps I didn't explain it too well. Maybe the pic will illustrate better.
The white "thingy" is a standard "cocktail" stick included just to give a sense of scale. I have made them half the size illustrated with not much more effort. Each one only takes between 2 and 3 minutes from start to finish. Painting covers up the slight twisting of the wire.

State of play at the moment. Nothing fixed as there is still a lot of detail work to be done. Gripes, bowsing in tackles, grab lines, crutches etc. etc. etc. Now looking forward to doing something else!

Looking very nice indeed Bryan. Just out of interest, what is the purpose of that bit of plating with three portholes between the davits?

Haven't a clue. Ideas? I think partly structural strength, a bit of shelter when a whoopsie comes over...your guess is as good as mine...perhaps it is just cosmetic, but I agree; it looks odd "but nice". It's also odd that there is a large gap in the sheathing directly above the plate, so I imagine it must have had some purpose. Beats me. I'm only trying to build the bloody thing.

Funny you should say that. Looking at the meagre plan I have there is no mention of a "Gents"...two or three for the ladies. At the "back-end" of the ship there is a dormitory for 50 male passengers. No mention of a toilet. But in the "Ladies" section I find both "lavotaries" and "WC's". What is the difference? On the plan I also find a "Ladies Room"...poor blokes. Perhaps the so called "fairer" sex had more clout then than we give them credit for...little darlings. I still think that the ship was originally built to trade between mainland Scotland and whatever wee islands it was sent to. Probably carrying 4 legged animals one way and another sort the other way. For all of that I really cannot imagine Sunderland sending (carefull here) bovines to London. But the ship did seem to be popular. Something to do with the cud chewers maybe. She went on until 1948 albeit in Algerian hands (minus the passengers I assume).

Sussed out the plate and the gap. The big plate must be for structural strength as the boat supports would be a bit weak over such a long span, especially in a seaway. The gap in the boarding is to provide decent space for the rearmost funnel stays. Since I started this build I have been constantly aware that although the funnel stays would hold the funnel in a fore and aft line there was very little to stop the whole lot toppling sideways. So it seems that the after stays do a bit of both and the forward ones mainly support on a f&a line. Ta,Colin...you concentrate my little brain wonderfully! Cheers.

You learn something new every day! I've seen that feature on models/illustrations of older ships before and vaguely wondered what it was for. Your explanation sounds very logical Bryan.

At long last I am coming to the end of the lifeboat saga....although I still have 2 cutters of different sizes to make. Pic 2068 has the rigging done apart from the (knotted) lifelines run from the spreader stay. Perhaps I can get on with the funnel now as a bit of light relief. I can see the rigging of this thing becoming a real trial. Do one thing and it prevents another being done. Ho-hum. Modern ships with their cleaner (if uglier) lines and enclosed fittings must make modelling them easier. But having said that, do you think that many modern ships have a "character"? I don't. Some of the modern fittings such as cranes and "dead-drop" lifeboats can pose a challenge...but when the model is of a ship that was built in the transient era between sail and steam all sorts of modelling problems arise. Good fun, if a little wearing at times.
Pic 2067 is the initial effort to make a boat embarkation ladder. I know that the lines should be double, but as that woudn't be noticed by many I did it singly. Not least that the actual presence of the ladders will be overlooked, but they should be there. They should also be on a "pallet", but for this first one I forgot to do it.
