metal pushrod to plastic clevis

I have some heavy duty plastic clevis/control horn matching pair at the control surface end and a 3mm threaded rod with a metal clevis on the servo end. I need to glue the metal pushrod to the plastic clevis, whats the best glue to use? I didnt want to solder a metal clevis to the control horn end as its a bit sloppy in the control horn holes.

AFAIK no glue will work effectively on nylon.

if you have a clevis on one end, all you really need on the other is a Z bend.

I tend not to have 2 clevises on one pushrod unless one is fixed. it makes it really hard to adjust if both are able to rotate, for obvious reasons.

Is my CG correct?

I have yet to find a reliable glue on nylon either. It is meant to be a threaded joint?

well the 3mm rod slides right in, unless its for 4mm rod? I scored the end of the rod up with pliers so the glue would bond better. I do have the soldered metal clevis for that end of the rod but it has slop on the control horn, looks like I need some 4mm rod and clevis or a control horn with smaller holes then!

thanks for your help guys.

If the clevis is sloppy in the horn you can make a CA bearing to take out the slop.
Just attach the clevis pin into the control horn hole you want. The take a pin and drop 1 or 2 drops of ca glue right on the clevis pin. Spray it with kicker and then break the clevis loose. You will now have ca type bearing in the control horn hole. Try it

Instead of all that I think I'd go shopping for a different control horn that fits the rod better.

I'm a big fan of either a Z bend or an L bend with a snap on keeper such as the Goldberg plastic snap on types or similar from other companies. Or even a small wheel collar as a keeper works well.

Either way you do NOT want to trust any glue joint between the wire and a nylon clevis.

nope especially on a plane that potentially could be flying 20km away from my location (ezuhf/fpv), Im gonna source some new horns or at the very worst drill new holes in the existing ones as there is plenty of room
