Baby I'm your man...
If one is stuck and does not move the right direction one should do what should have been done in the start - Listen to your inner voice and listen to the others
Not: "I-wanna-have-a-ropewalk-and-do-same-nice-ropes-as-seen-on-the-modelling-exhibition" but "I-need-great-ropes-for-
my-Vic"
That changes a lot as I am building a completely different scale. Changes a lot towards the materials and the usage of the walk. So freshly focussed back to work:
First listen to the others: Oli/Modellbaumechaniker and Holger/Pollux from my german forums gave me the right hints for the right materials. Fil au chinois and flyfishing lines were the right hints!
http://www.neheleniapatterns.com/html/filagant.htmlhttp://www.baker-flyfishing.com/shop/bi ... php?v=n183And this is what came:
The bigger bobbins are the fil au chinois, numbers for the colors see the picture
The smaller bobbin sare from the flyfishing, Uni-Thread green 8/0 the thin one, orange 6/0 the middle one, the thick 3/0 and the superthin 17/0
The fil au chinois is cotton with very little fussy bits, the Uni is free of fuzz.
The Uni has a large range of colors avaliable, unfortunately not all colors in all sizes. The 8/0 and 6/0 are great for my purpose, the 3/0 has the great appearence of colored dental floss and the 17/0 is also quite uneven and transparent.
First tests proved to be the right direction sizewise
Left the fuzzy thread from the supermarket, my thinnest possibility before this date. Then comes the fil au chinois, the Uni 8/0 and the Uni17/0, always the original strand, then two, 3 and 6 stranded with blocks of 3 mm, 2 mm and 1,5 mm for comparison.
And the first test also showed that turning the axis by hand is a tad tiring and the cordless screwdriver is a little bit unhandy and also too insensitive ...
...
So ...
... reopening the Fischertechnik box from my youth, getting the motors out, glueing them with double sided tape onto the machinery, here the pretwisting side to be seen ...
... and the laying side ...
... the motor can be turned sideways to reposition the hooks ...
... and felt was put untderneath for easy gliding, and a steel ruler in the middle to control the movements of the sliding parts
Both sides were clampedto the rail to be able to put the yarn properly. After chasing behind the bobbin for several times, a holder like the sewing machines ones was introduced, and from there the the yarn was brought to the hooks of the pretwisting side - I am showing a 6-stranded rope - ...
... and after 3 times twice forth and back ...
... the yarn was fixed on the laying side.
The steel ruler shows the movement of the slide - I use 10% on this rope - loosen the clamp on the laying side, the pretwisting hooks start turning and the opposite slide starts moving miraculously towards the predrilling slide
If the required distance is achieved, I clamp
both sides onto the rail, and the three strands are laid until the required tension is achieved ...
... some CA for fixing ...
...going with the fingernails over to release unwanted tension ...
... and you can make a clean cut.
Lessons learned
You can see two things:
First: I am not using any more the little guide block.
No difference to be seen apart from that it is much more even
Secondly: I am fixing
both sides while laying the rope! In the first trials I had the trouble, that the start of the rope was coming out nicely tight and the second half was much more loose ...
I realised that at the start of laying the pretwisting slide does not move, and the shortening of the rope is only compensated by the lateral spreading of the yarn. Just later on the slide starts moving. But it was not just after I forgot once to remove the clamp of this slide and got out a great and even clean cable that I realised, that the loosness of the rope came from the missing tension on the other side.
The next tests without the guide and fixed slides prooved to be successful
Just if the motor is having to work too hard, I stop it and I loosen the tension a tad by carefully moving the slide and then contimue.
Come on baby...don't fear the Reeper
Baby feel the thread...don't fear the Reeper... and the part that should be pronounced is:
