Is this clicking noise normal for a tall case rack strike? Is there a way to reduce the sound of it?
Yes, this is the lever I had in mind. It falls by its own weight, no spring attached. The sound happens when it falls down from a tooth of the rack into the next trough. So, the sound is "normal". All you could do to minimize it would be to soundproof the case, but that's not something one would want to do (at least not me). Or, maybe it would help to glue a piece of rubber foam or similar to the side of the lever and/or the rack. That might reduce the vibration somewhat. Self-adhesive weatherstripping comes to mind. Probably it is best just to get used to the click.Yeah, I need to reduce the resolution for a longer video - as it is I had to chop this one in half. The loudest clicking of most concern is just before the strike, so the second one is best. This is a rack and snail. Watching it, the noise is all associated with the lift and dropping of the piece above the rack in the upper left.
I have another similar unsigned movement that sounds the same, that is why I asked it if was normal.

The gathering pallet is usually surprisingly silent in these movements.isn't that more the gathering pallet than the rack itself? you might try adjusting/smoothing the little pin that catches the rack teeth...
Yes, the masking tape seems to fill most of the space that the rack advances so it can't fall back as much and it doesn't make a clack.you're getting a double-click... and the masking tape is just making it a single click.
not sure there's a way around that, but you might want to get in close with magnification and see if you can figure out why the double-click is happening. i wonder if a rook hook tip made out of delrinAF would work? hmm.....
Lazy creature of habit. I take the videos on my phone and email them to my computer to store them in my clock folders and then upload to Youtube from there. I keep them short since there is a limit on email size. I know I could load them to Youtube from my phone, but I still want them on my computer. I know I can use a USB cable to transfer them, but that means I have to go find one. I have a Thecus NAS and on my old phone I had an app that automatically pushed new photos and videos to the server, but when I got my new phone, the app didn't transfer and is no longer available on the Play Store (at least I cant' find it). The new Thecus app doesn't seem to have that feature.p.s.: why the short videos? just dump 'em up on youtube no matter how long they are and then embed here.
That would quiet the clack, but I don't see how it would dampen the click. As I mentioned, I would also be concerned about the rack not moving far enough for the rack hook tooth to drop behind the rack tooth. There is some variation from tooth to tooth on the rack, so the gathering pallet needs to make sure it pushes the rack far enough for every tooth.The gathering pallet is lifting the rack too far, shorten the tip of the pallet, so the lock will fall right in to the valley of the rack.
Did you try the viscous oil trick? That should make the landing softer.so its tip doesn't land hard in the valley, but sort of slides down
Very viscous, like for a manual transmission (SAE 90?). You might even try a grease like main spring grease. It will probably stay better put. The choice depends on how heavy the lever is. It still needs to fall in time to catch the rack, but slow enough to hit less hard and a bit later.No, but that's a thought too. Do you recommend any particular weight?
I think this would work. You'd just need to duplicate the profile achieved when you placed tape over the hook. There's plenty of material there so if you're very conservative and methodical I don't think you'll be doing irreversible damage to the movement. In "dressing" the rack hook, you may even be compensating for wear.Maybe if you rounded the hook tooth at the point a little it would at least soften if not solve the issue
