If it works here is how I do line ends. The first pic is tools and hardware. Second pic is the tubing on the cable. The short tube is the one that will get swagged. Notice that as this is .015 I cut a short peice to go thru the long tube and there will be a total of five lines of cable thru the swagged tube. Third picture is bending the long tube around a smalll pillips screwdriver for the loop. The next pic is the cable after it has been put thru the tube that is going to be swagged. Notice the long line is the control line that will be pushed back thru the tube so it can be swagged.
Last picture is the ends of a new set of .015 lines that will be cut to length and finished in Tuscon at VSC. Tried to correct the bluriness. DOC Holliday

Doc,
Wrapped my first line ends in nearly fifty years, and found out my fingers aren't near as nimble as they were! ::)
They turned out OK, but the shrink tubing I used over the wraps makes them look much better! ;D

When I get home I may do this again as I have been sent some suggestions on how to take pictures. With the new program the wife bought I can back off to get focused and then crop the picture. I find swagging so much easier than wrapping. Have fun, DOC Holliday

My line wraps aren't pretty, but I just don't trust lines crimped with the available tooling and materials. I've seen some awful examples of mashed crimps on various ARF and ARC airplanes, and even ready made flying lines.
The AMA instructions for wrapping lines is also confusing to me, because the last time I checked they specified soldering the wraps. From everything I've read and heard lately, soldering is a good way to produce a stress riser, and subsequent failure of the lines. Has this changed?
