Throttle cable build and repair
I recently broke a throttle cable at the bulkhead fitting on the end of the 7mm housing. This piece had an m6 x 1.0 stud on it that held the housing against the fan cooling structure (vintage lynx b).
I have been trying to source out materials for building new cables. I am not able to find these cable housing end pieces, bulkhead threaded rods, for 7mm or 5mm cable housings. I am not able to find long (40mm) cable end 5/32 ferrules to clamp down in the carb.
I am trying to repair this cable to have as a spare and build several new ones as well.
I am trying to use the existing aircraft s.s. 1/16-3/32 7x7 cable.
Does anybody have sources for these parts? This cable may be decades old and I may need to rework the pedal if parts can't be sourced. The cable goes from a 7mm housing on the carb end to 5mm housing thru the frame to the pedal.
Is there a better way to build this cable today?

I then get bicycle brake cable that has the tyflon lining since it allow the cable to slide easily inside it. While at the bicycle shop you can also get the ends that are adjustable for you mounts at the ends of the cable or take them off any bike that is being tossed. I also made the end that goes into the carb end by turning down the end of a round rod to fit into the standard carb ferrule and drill the other end out to slip the cable into about a 1/2" and using a press crimp it in place. I have never had a failure but you must have a throttle stop at the pedal end so as not to be able to pull the cable out of the carb adapter. I also on my throttle pedal end use a short piece of 1/8" strap with a hole on both ends and use a 1/4" bolt with a fender washer and loop the end of the cable around the bolt and tighten the bolt to hold the cable in place. Also when making the cable it helps to use a torch or TIG welder to cut the ends of the cable which welds the strands together so it won't fray.
The hardest part is drilling the 1/16" hole in the round stock without braking the bit off. I haven't made any for years but if adjusting the cable correctly you should never brake one.
