@@mtb4maine No. I do generally roughen the ends of the carbon fiber rod with a file (sandpaper also works well) whenever I bond the rod to the pushrod ends with JB Weld (or CA glue), but I do not roughen the cf rod ends in this case because there is no bonding; it is purely a mechanical fastening.
With my NME kit those bushing would not fit on the rod at all, I needed to reduce the diameter by a few .001” I guess my question was more if anyone has had the same experience.
@@mtb4maine On my NME kit, fitting the carbon fiber tail rod onto the metal rod ends was a tight fit. I used a hammer to tap it in. It is important to insert the carbon fiber tail rod all the way onto the rod ends until until it bottoms out, otherwise you risk it coming loose. I guess reducing the carbon fiber rod outer diameter with fine grit sandpaper would have worked, but I preferred to lightly tap it in with a hammer.
The carbon rod ends WILL split and deform a bit when using these reusable "push rod ends". This is not an issue whatsoever as far as safety and performance of this assembled unit. It would become an issue if you were for some reason wanting to use the carbon rod itself in another project. In other words, the assembled push rods ends could be unassembled and be used in other projects, but not the carbon rod itself unless you saw off the "damaged" ends.
What John Hamel said is correct. They will split in the ends but because it doesn't allow expansion in the straig portion this split doesn't travel further out
Great video Auggie
I personally use Blue Loctite 243 on the threads, but no, I do not use epoxy, or JB Weld, or CA glue to bond the metal ends to the carbon rod.
Did you have to take a slight amount of sandpaper to the road ends?

I’ll try that next time. Thanks!
Hello Auggie,
Is the carbon not cracking, because its a verry rigid material?
