Review: Silence is golden, but costs only 10 cents a piece - Did the trick. Most of the metal stairway doors and the elevator doors in our condo building had lost their rubber bumpers over the past 25 years and clanged loudly when they shut. We could see the small holes in the door frames where there used to be bumpers, so we took a chance and ordered these. They're a little hard to fit into the holes without an insertion tool (takes about a minute per hole to wiggle and wedge them into place), but once they're in place they work great. In about 15 minutes I was able to fit these silencers into all the doors that were missing them, and it made a huge difference. No more clanging! The doors and door frames were made with the expectation that these types of bumpers would be used, so they haven't created any problems with doors closing and latching. All they do is get rid of the noise. Peace and quiet for a whole building for ten bucks. Now that's a bargain. Silence may be golden, but in this case costs just ten cents a piece.
Review: Replacement for Gottlieb rubber stops in pinball machine restorations... - Bought under the impression these would work as a replacement for Gottlieb black grommets for pinball machines (particularly in the chime box). They do fit, and they seem to work. They are of course not black, so they kinda look un-original, and wish they were available in black so at least they kinda passed the 'visual and sniff' test of a discerning trained eye. But, they do fit, and do work. Thanks for the idea, recommend 'kinda' for this purpose. What i have done in the past via Tim A (PHoF) recommendation is take off the relay bank on the main boards and use those rubber offsets. Done that many times, doens't take much time, and they are in fine shape and work great. However, as I get older, and don't want to do things that take much time any more, just putting these in makes some sense. Saves 5-10 minutes, yet doesn't keep it original. However, neither does taking off relay bank rubber, so 1/2 dozen or another is issue, and solution is use new product for the purpose. We'll see how it lasts.
