SMS Karlsruhe by Wreck1919 - 1/100

[Wreck1919]

Hi, so here is the first one. I hope to improve execution for the remaining spars/yardarms. Getting the vertical ropes (stirrups) to the same lenght and position is tricky for me.guess i will find a method by the time the last ones a made. Fortunately a photograph shows footropes/stirrups as also not being straight. Thats my excuse 😎.

I gather the fact that the stirrups are slightly curved seems to indicate that they were made from wire rope.

 

You can slightly soak stirrups and footropes in fast drying varnish and hold them in shape, while the varnish dries. Use solvent-based varnish, so that you can soften the arrangement, if you are not happy with it at the first go.

 Sasha, your path is right! 👍
  Impregnation with varnish or cyacrine glue will solve your remaining problems. 

[Wreck1919]

Progress… nothing broken yet. Missing the varnish/„natural“ slack still, but will experiment.

Halfway done. Unbelievable how many lines/ropes are on that mast given its not a sailing ship.

Oh and thanks eberhard/valeriy for the comments about the position of the footropes. The are shown to be „aft“ /behind the spar/yardarm on the plan, but i totally missed that detail. 
cheers sascha

 Sascha, if I may. The distance between the foot ropes and the yard should be waist high. Your figure indicates that there is too much distance between the foot ropes and the yard. 

[Wreck1919]

Morning(?😎) Keith. Yes, of course you may👍🏻. the stirrups are  6.5mm(0.25“??) so maybe the picture wasnt good. So here is another one where my inspector is being hoisted up.  Note that i tied the rope under his arms and not around the neck since his services will still be required 😎.  The shape of the ropes is work in progress, am still experimenting (off model) with varnish.

Edit: and i did cheat with the attachment points for the ropes  under the  platform, because i forgot to include them when building. Now its too late.

Rigging continues with upper signal lights. I didnt think about those when building the mast, so they too have no upper attachment points (cheat with knot and spare stirrup) , something to remember for the next model 🤪. 
 

[Wreck1919]

Another update: rigging is almost done. All that can be attached to the masts off model is finished. Remains „only“ to do the lower attachment points on deck. How to attach the signal lines on the foremast to the bridge without tearing everything apart is still a mystery to me though…🤪. Looks a bit wild now but once straigthened out it should be ok,..i hope.

cheers sascha

[Wreck1919]

Another update gents. Lower attachment assemblies were made. The rangefinder was mounted and the main mast ist now glued in place and two of the holding cables attached. The others will havE to wait a bit as i want to finish to aft deckhouse off model before.

happy sunday

Hello all, here a few pictures of the current state of affairs. Nearing completion. The big things missing are Davits, stretches of railing, antennae and pieces of equipment on the stern and hull. Stuff on the hull is an issue because the paint i used is discontinued and any trials to match with a new supplier were so far „not phantastic“
cheers sascha

Sascha,

 

You have created a beautiful model! And it is even more impressive knowing you used simple tools, and you have great skill working with them.

[Wreck1919]

Thanks Phil (and others for their thumbs up 😎). I must admit to be a bit narrow minded when it comes to modelling🤪, so i didnt look into any sailing boat - sorry for that term if it isnt correct - builds. Mistake. I did check your albatros thread phil and while i dont get half of the specifics , it makes for a great read and explains your journey well. Thank god ww1 ships dont have visible wooden planking 😬.

cheers sascha

 

[KeithAug]

Lovely model, beautifully executed.

[Wreck1919]

Hi all, work continues. Now prototyping the davits. Most parts davit head, cleat,…not glued yet. Experimenting with best way to make them. Davits themselves still need cleaning and a bit more tapering towards the head.

cheers sascha

 

[Wreck1919]

Morning all,

just a short update : four davits are ready (2 minus the  colour). Shipyard now closed due to vacation. Have a great summer !
cheers sascha

 

[KeithAug]

Enjoy you holidays, I look forward to more eye candy when you return.

[Wreck1919]

Hello all,

the break was longer than i thought. First a restauration project (ww1 battleship) and then the job got in the way of continuing on Karlsruhe. 
finally davits are finished. The two missing pairs are of course of different size than the ones i had already made, so new construction. This time i wanted the „head“ to be flush with the rest so the H-profile now consists of 5 parts so the head can be slipped on rather than „over“ the thing. Easier to see on the photograph than explained. So until am done with the boats, no more talk of davits 😎.

cheers sascha

Beautiful!

Hi all, 

made the blocks (for pulley) for the smaller davits and completed  a cutter plus rigging. The boat itself is from the workshop of a friend and is amazing , note the clinker planking . I just assembled it,added a few things and painted.

cheers sascha

 

[wefalck]

Nice progress!

 

Looking at the chains, from which the boat is suspended, I think there should be a third one, leading to the stem- and stern-posts respectively. These chains are intended to limit the boat swinging forward and backward, when suspended from the davits.

I think at that time the KM also used slip-hooks to attach the chains to the lower block of the davit, but this may be difficult to reproduce at this scale. The slip-hooks are there to ensure, that both tackles are releases at the same time, as otherwise the boat might be turned over in a sea.

If you don't have it yet, you should perhaps get hold of a copy of

 

BRIX, A. (1911-1929) Praktischer Schiffbau - Bootsbau (reprint 1982).- 394 p., Norderstedt/Hamburg (Egon Heinemann GmbH). 

 

The 4th to 7th editions would be more or less relevant to the period of SMS KARLSRUHE. Some of the editions are also available in digital form.

Moin Eberhard,

yes i saw many drawings with 3 chains,… but no photograph. So i decided to take a shortcut 😎. Also the hook should be the other way round (upside down) but that was too difficult for me to make.

on the sliphook: absolutely correct . There was a chain assembly with a „spannschraube“(cant think of translation now) and sliphook to fix all in position. This assembly was attached to the side of the davit head(upper) and side of the block (lower). The problems here (for me) were: cannot reliably attach upper end to davit head(too small) and distance between head and block when boat is on barrings is short, so the whole „spannschraube“+chain+sliphook assy would need to be very tiny. On top of that - at least off model - i can adjust the height of the block/tension of chain so that the ropes are (almost) straight. If i wanted to build the aforementioned assembly with the sliphook, then that would not only be tiny, but also have to be pretty precise in lenght which i dont believe i can do. 
i have yet to be brave enough to install the whole thing on the model…🤪.

Ps: yes i have the Brix 😎

Hi eberhard (and all),

on the picture with the swung out boat is the assembly that you mentioned (blue circle). You can (??😎) see the slip hook at the bottom , the „Spannschraube“ and chain. But only if you know what you are looking for.

the second photo of the steamboat „shows“ no 3rd chain - this should go towards the bow if it were there. Maybe its there but it was taken off before the photo was taken. If thats so, then my model shows that status. Hows that for an excuse .😜?
cheers sascha

just noticed that my markings dont show up in the photos. No idea why. SorrY.

Edited November 18 by Wreck1919

Actually, the three chain would not be visible from that angle, the would be too low in the boat I think 😉

 

'Spannschraube' is normally translated as 'bottle-screw', because in its closed form it resembles a bottle.
