Replicating spliced cables
« on: April 10, 2013, 02:55:48 PM »
Friends,

following up on the "replicating turnbuckles", I would like to ask for your preferred method for faking spliced cables.
For making turnbuckles I use the method as decribed by Des on this homepage, but I think that using even very short pieces of 0,5mm tube for the splicing looks inconvincing. I habe tried drilling 0,4mm tubes, but without success (and yes, the drills are brand new) - the smaller tubes seem to be of a much much harder sort of brass.

The best way I have seen so far seems to be Bertl's, who does not show the splicing, but the protective leather cover around the splice. Unfortunately the insolation tube he uses is way too expensive for me (I have read something around 200€ for 20cms?).

Your proposals, please.

Stefan

Stefan.

One method I've tried is simply to grip the free end of the filament (I use Invisible sewing thread charcoal) in pliers/clamp/whatever and loop the end through an eyelet or turnbuckle. Then I twist to intertwine the loose and fast part of the filament just like creating an eyele and apply Cyano and homld till set. Once set I trim and or add more cyano to build up a *covered* effect.

It can be a quite hit or miss way but if it gos wrong you can just cut the disaster away and redo.  It takes a little practice but I know you are capapble.

I use this metho now to affix the non-turnbuckle end of cables and still consort to the old short thin brass tube method to attach the other and tension the cable.

I think David Parker of Air Modeller fame did a similar thing with Mr Surfacer on his LVG build.

Tie a blood knot (Grip knot) to an eyelet before inserting said eyelet. Make sure you wet the line before snuggling the knot up tight. trim waistline away - nail clippers are good for this.
Run white glue over the knot with a tooth pick. Allow to dry before painting.

Good luck!

gcn: you are right, David Parker faked the splicing by painting them. But he drilled through the complete wing for his rigging (he described that in Air modeller issue 25), instead of using eyelets. His procedure thus is incorrect in it's own way...

bobs_buckles: Interesting proposal - I know of this way to join fishing lines, I will give it a try.

I have not still tried it, but... have you seen this?

This is the method I find most intriguing and the one that I think is used by Bertle, Costas and a few other extraordinary modelers.  I would just like to know what size (id and od) to buy to accommodate two lengths of 1lb and 2 lb monofiliment.  I'd hate to spend that much on the wrong size. 
Cheers,
Bud

have you tryed heat stretched q-tip rod. they call them cotton buds abroad. just like you would stretch sprue over a candle but the q-tips have a hollow plastic shaft  if you get the technique down you can get them very very thin.

I've used that technique on a few of my models with varied results, Scott.  What I ended up with is something very much like brass tubing in wall thickness.  I ordered a length of polymide tubing and it just arrived.  Each size comes in two different wall thicknesses.  I ordered the thinest which would still accomodate two lengths of 2lb test.  I tested it by forming a loop of monofilament with a 1/8 piece of tubing.  It's very tight, but it fits and looks fantastic.  I think I'm sold on this stuff.  My first practical application will be in conjunction with Gaspatch turnbuckles on my Halberstadts.  I'm really looking forward to trying this out.
Cheers,
Bud

Bud,

do you mind adding some fotos to your description? I am not sure that I am able to understand your description completely...
