Modifying a Green Glue Whisper Clip

I was wondering if any one has any thoughts on modifying a Whisper Clip or maybe I should say modifying a portion of a Whisper Clip. I started a thread about this type of clip a year ago and got some good info. But now I am planning to alter them and will likely start to install them in the next week.

The Whisper Clips that I have are these.



The reason why I have these is they are much cheaper than the standard clip plus they were readily available. I should also mention I have only seen the clips available in Canada as that is where I am and in Australia. As I have been experimenting with modification this is what I have come up with.






I attached the clip to a metal plate and on the back of the plate I have a piece of closed cell foam. You can see that the screws that go into the studs have a rubber grommet attached to the plate to keep direct contact with the screws to a minimum. I also have some rubber bushing between the Whisper Clip and the plate. I am hoping that in the end it will be similar to the standard or should I say full Whisper Clip set up.

These clips will be holding up 5/8" DD and GG.

Anybody have any thoughts? Am I a bit crazy to go to this lengths to modify the clip?

Thanks

This is one of the ideas that I was thinking about.

I guess I was hoping to emulate the original Green Glue sound clip.

I will be adding 2 sheets of 5/8 drywall with GG. I am also currently installing drywall on the underside of the floor board between the joists with GG.

The grommets are actually very cheap. They are grommets/nipples for tattoo machine needles that I found off of Ebay and were about $2 for 100 shipping included. I was going to use another closed cell foam material that I can buy from Costco which costs about $0.50 a square foot and I was thinking of using a different plate which cost about $0.12 each.

Overall it is a cheap modification but it will be time consuming to modify all of them so I am wondering if it is worth the trouble.

Thanks. I think I will leave the clips as is, with the exception of the grommets since I already have them. I figure they cant hurt and if I don't use them they will end up sitting on a shelf until my wife throws them out.

I didn't think you should use drywall screws but I am glad you confirmed that. From what I understand drywall screws aren't that strong. Which is fine when you 15-20 screws holding in a sheet of drywall but probably not so fine when when 6 screws are holding 6 sound clips which in turn are holding 2 pieces of 5/8 drywall.

That thought has been crossing my mind, so I guess I am not being a bit paranoid thinking about this. I'll re-evaluate what I am going to do.
