Kolb guys C
 
  In the latest copy of Sport Aviation Magazine C there is an article about securing the cable thimble with stainless steel wire C then soldered the wrapped wire (3 locations).
 
  This method of securing cable fittings allows for a very slender cable end C rather than that annoying nodule of a Nico lug.  If they are finished off with a covering of heat shrink C they look very professional.
 
  BTW C although I haven't read the complete article C yet C it appears as though the author also did some stress analysis tests (destructive testing). 
 
  Has anyone fabricated their cables before with this kind of method?  Really does look nice!!

I haven't seen the article, and it may be ok but Caution would have to be taken to avoid heating the cable (obviously)In A&P school they taught us how to do woven cable ends about the thimble. I had forgotten about it.
We had to make our own fixture to hold the works while it was being woven. I'm not sure how small a diameter cable would be eligible
but it is a secure method. At one time it was illustrated in the 43-13 literature.
Restorers of authentic antique airplanes sometimes insist that all their cabling be done this way.

Hi Bob C
 
  I glanced at the article C too C and like I said C I haven't read it fully.  But C I did notice the author mentioned something about testing the soldered fittings.
 
  A quick scan of the products reveals he used 95% tin/4% silver matrix.  It melts and flows at 475 degrees.  Not likely to do much damage to the cable at those temps.
 
  I'll read the entire article this evening C but it sure does look like an interesting way to make your own custom cables.

I would be very leery of using solder on structural cable. Not only is
there the uncertainty of how well the solder has flowed and bonded to the
cable, but the flux can be corrosive. Also, the solder stiffens the cable,
which can lead to fatigue cracking. Finally, there's the effect of the
heat on the heat treated cable. I'll stick to the well proven Nicopress
sleeves.
