Not sure about 20lb bass, but here is the camera mount on my Rob Allen 110cm railgun:

Its made from railgun vertical reel mount bracket, that has been bent out to allow for camera to clear the barrel. Camera is 3.2 megapixel, takes stills or video. Waterproof to 125 feet. Camera sits slightly cocked to the inside, so that it centers on the muzzle and approximately where shaft is going to end up. See if you can make out the LCD screen to get the idea ... I'll try and post a quick photo and a quick video that camera takes shortly.

Also, camera swivels to allow easier band loading. When bands are loaded, and camera back in position, outside/over band just slightly touches the corner of camera plastic housing .... but I think when fired it will not interfere with it. Contact is very slight when band is fully stretched. We'll see....

As for the bottom line release, I am planing to install small "L" bracket on the mount bolt, so that it "holds" the line out and away from the whole thing ... when line release drops it, it just drops out and away from the mount. Even tho it looks like it will work the way it sits now, I just want to prevent any possible tangles.

Hope this helps
