What tool do you use for crimping ‘pull pull’ ferrules?

Thank you Ron?

I just use the pre-rolled kits from SLEC.

Sea fishing tackle shops are a good source of wire and crimps, at good prices.   I like the nylon coated trace wire.   Always crimp with side cutters, middle crimp perpendicular to the other two, then cyano for good measure.   I also heatshrink usually, keeps the tail end a bit cleaner at our grass strip.

 

If it’s a large plane I usually incorporate a swivel to stop the wire kinking when being adjusted at the clevis end.

Not familiar with a 'swivel'... what's one of these?

Swivel

Thanks Ron.

 

Worth exploring, as they come with snap links too which could conceivably be useful if, e.g., one wished to replace a cable and not cut it.   ball bearing swivels are also available but expensive.

Nah. Swivels are for lines which twist in use. Pull pull lines don't, as they are anchored at each end.  To remove any twist during adjustment, just remove the clevis, tease out any twist and reattach the clevis. A swivel doubles the number of crimp connectors per run, which is a bad thing. KISS.
