Adding shielding to existing cables

So I have some interconnects that are picking up all sorts of RFi. I know this for two reasons, one, as I move them around the noisy/buzz sound changes, and two, when I switch them out for shielded interconnects the noise goes away.

so, I bought some tinned copper shielding and some new RCA plugs. I’m going to cut the existing RCA plugs off the existing cable and install the new shielding and new plugs. The thing is the new plugs have a plastic body so there is nowhere to easily connect the shielding to ground.

I was thinking of running a pigtail from the shielding and attachIng an eyelet to ground it to my preamp since there is a grounding lug. Would this work or is there a better way given what I intend to use?

@dgarretson knows his stuff.

All I want to suggest is, maybe don't hack your favorite ICs as your first one? :)

Sometimes I feel I’m being misunderstood or people aren’t reading through completely. No offense to anyone. 
I’m not going to hack up my cable (yet). I’m going install a shielding with pigtail I can ground to a source. I just wanted to know if that would work. 
I have other cables with shielding that stops the same noise I’m picking up from the other unshielded cables. 
That being said the cable I like is one of my least expensive by some margin so, if I ultimately hack it up, it won’t be the worst thing in the world;)

Yep.  That would work.

You will be adding some capacitance, be interesting if this changes the quality of your cables. :)

@lalitk "DIY crap like Belden" Guess this guy doesn't know much about Belden, been around longer than he's been alive & make more than just a few cables. Belden 8412 with Switchcraft 3502ABAU gold plated plugs, you go ahead & push your expensive cables meanwhile I'll make my own & use them everywhere with zero noise, maybe do some research before bashing something you have zero experience with.
