Re: Making stretched sprue and Rigging with stretched sprue

Hello all,

I have experimented with the Modelkasten 0.047 mm wire ( Nitinol-- memory wire)

on my 1/350 Tugboat Maanzee...

the results were quite pleasing-- but I still happily used Stretched Sprue for the halyards etc !

http://www.modelshipgallery.com/gallery ... /index.htm


on my latest 1/700 model ( the Liner Normandie)

http://www.modelwarships.com/reviews/sh ... /index.htm

I found the ( pretty thin wire! ) OK for the thick shrouds ( even on the real thing!)
but all antenna and halyards etc were all done using stretched sprue


I illustrate the difference of the sprue versus the 0.047 mm wire below!

I prefer sandlewood - very aromatic! Also covers the smell of glue and paint. :big_grin:

I use Humbrol ' Matt Cote ' ( the one in the glass jar ) ( image below )


thinned with white spirit ( less aggressive than Humbrol Thinners )

==> high grab, quick dry

allows a little bit of adjustment as well.

Best wishes

Attaching vertical lines to horizontal antennas should only be done using Matt varnish as an adhesive-otherwise the longitudinal will melt and snap if poly cement is used..

Jim when you say a Matt Varnish are you referring to a type that would be used for wood or matt clear for plastic? Thks kevin

Very helpful.

I have been wondering what to do about rigging.

I have access to very fine surgical threads (used to sew capillaries and tiny veins), which I was thinking of using.

But I have used stretched sprue before on model tanks for aerials/antennae.

This looks like "It" to do the rigging on my 1/700 ships.

For heat tightening rigging on large models, I have found that the best way to hold it above my head is to drill a hole in the bottom of the model, and hang it off of a screw that is very securely drilled into one of the high shelves in my workshop. The shelf is anchored into the wall of course.

Hello David M--apologies for late response--I have been away and terribly busy at work also....


holding model above you

not much help there 1/200 is pretty big...

i would try and test your marriage and get your wife/partner to hold the model whilst you apply heat/ smoke

Katrin does it for me upon occasions...

( Mauretania

had a huge stainless steel plate attached to the bottom of the case-- and was too heavy for me also..

Jim, Thank you so much for this great tutorial, I was able to successfully make the stretch spruce rigging and install it on my 1/200 Arizona after reading this thread.

The one question I have is: do you know of any good ways to tighten the rigging lines without having to hold a model over your head?

I am a little worried if I try to hold my 1/200 Arizona over my head with one hand I may drop it ...


Thanks so much

David.

thankyou from this newbie
this howto helped me with my 1/700 rigging on my bismarck(my first ship)
i just finished adding rigging to a sinking freighter
it's sooooo easy with this method
many thanks
this is a great group to be in

It about sums up why I use sprue....

Fishing line --even the very finest --as mentioned in 1/700 is too thick fro my liking
==> and also does not allow reliable consistent sag to be created.
Copper wire does a good job of this- but can be very prone to kinking and dislodging when working on it

( especially in 1/700 scale)....

Here are a couple of masters of copper rigging -both of whom generally work in in scales of 1/384 upwards

ie 2 x as large or bigger as my teeny models...

have a look here:

Good morning, Jim,

Thank You very much for the two very awesome links. Until now, I didn't know the works of Mr. Robert Wilson and Mr. John Prothero-Thomas existed. I can only sit down pout and cry at the level of artistic talent showcased by both gentlemen. Including you, I now have three role models. :)

Sometime ago in this forum I said "Bah" about sail ship models but after viewing both gentlemen's absolutely sublime works of art, I have come to appreciate the beauty of sail ships Alot more, I mean it. Scratchbuilt, no PE sets and all that intricate and lovely rigging are sights to behold. Truly inspiring.

First of all thank you for all the replys. I will definetly re-consider doing it with fishing lines.

So I guess I need to make lots of practice to have good results (In other words, for lines which have equal thicknesses)

Hi,

I once tried nylon fishing lines to build railings at scale 1:100 on one of my models. I discovered they are prone to shrinking after a while, I had to redo the whole railing once again, with PE stanchions & brass wire.

working at scales 1/350 to 1:700 asks for stretched sprue, I see no other way to work properly.

This is by the way why I don't work at those scales :big_grin:

Without speaking for others, I think that there are three main features that makes it attractive:

- for small scale models, say 1/350 and below, fishing line (nylon monofilament) is far too thick.

- there are special techniques for attaching the polystyrene filaments by partially dissolving them and thus welding them to the attachement point; the same technique is used for attaching them to each other.

- the polystyrene filaments can be tigthened by gently reheating them, which makes them shrink.

If you don't like these home-made polystyrene monofilaments, you can use copper wire (readily available down to 0.05 mm diameter) or fly-tying threads (that go down to similar diameters and are available in many colours).
