I feel as though I have to comment on this noise again since the original noise source may not have been from the rest at all. At the 3-D course today, I found that my module screw had started to back out and was slapping the cam upon release. Shame on me for not checking the tightness of such a critical component, but it's thoroughly thread-locked now and I don't suspect it'll give me problems again.

Regardless of this, I am still getting a "hitting" noise when I actuate the rest manually. It's not the noise of the loose module, obviously, but is coming from the inside of the rest. I hear it when I pull the cord to fully extend the arm, then suddenly release it, as I would expect to happen during an actual shot.

I had the rest totally apart today, and figured it was the brass cylinder slapping the aluminum housing as it reached the inside bottom of it's travel. I also suspected that the head of the launcher arm was hitting the inside of this aluminum housing. I tried to silence this noise using two different materials:

1. soft rubber strip with adhesive on the back, about 1/16" thick
2. Velcro, using the soft, thick side of the mesh

I placed it all along the inside bottom of the aluminum housing and on the portion of the housing that would be hit by the head of the launcher arm. I reassembled and figured this would at least dampen the noise. Unfortunately, it's as though I did nothing, leading me to believe I have the contact point that I cannot see somewhere inside the rest.

My questions are:

1. When manually activated by pulling, then suddenly releasing the cord, do you other Drop Zone users hear a similar noise? I describe the noise as the eraser end of a pencil hitting a wood table. It's loud enough for me to want to eliminate it!
2. You guys have any speculation as to what may be causing this noise?

There aren't many moving parts in this thing so it's almost embarrassing not to have found it yet.

Any help or description of what you find with your Drop Zone rest would be appreciated.

Thanks,

Fritz
