Also try looking at the material used for covering drafting tables.  I have a smaller piece of the same material that I use as the work area on my bench. One side is the classic green the other size a cream color and it's about 1.3 mm thick. I'm not entirely sure where mine came from it was left over from when my father used to to cover a drafting table a very very long time ago.  looking on Amazon gives you the link below kind of the starting point.

Ohh, and the parts dont bounce much on this? The color green is available on amazon for this.

They surely bounce on hard material, that is also a reason why a bench mat is used. Another trick is to have a large drawer and keep it opened.

Bounciness is directly correlated to hardness. Soft things absorb energy by deflection/bending, so less is dissipated through reflection/bouncing. Drop a cotton ball on a pillow, and it doesn't bounce (soft/soft = mutual absorption). Drop a cotton ball on a steel plate, and it doesn't bounce (soft/hard = cotton ball squishes and absorbs the energy). Drop a steel bearing on a pillow, and it doesn't bounce (hard/soft = the pillow squishes and absorbs the energy). Drop a steel bearing on a steel plate, and it'll bounce nearly to the height from which it was dropped (hard/hard = no squishing, and all that energy has to go somewhere, so it is converted to kinetic energy in the opposite vector in the form of a bounce). Newton's third law of motion.

The converse to this is that softer materials are less durable, and more difficult to work on for other reasons. A flannel backed vinyl work surface would be pretty soft, but wouldn't last very long at all. Also, you'd probably find it difficult to write on. If you're looking at materials, look at the durometer. I've seen SBR sheet rubber used successfully and over a long period of time (same stuff as car tires). I have some newer stock of the same in my shop, and it's good stuff for a lot (once the new tire smell is gone), but it's probably as soft as you'd want to go while still being durable.

Thanks for the informative reply. Sorry i didnt see the notif.

Yes i know the bounciness is related to the surface hardness. But i meant is like does laminated or formica tops reduce somehwhat of the small parts bouncing and flying?

Im making a new bench so thats why i asked

Reduce the bouncing/flying compared to what? If the laminate/formica is softer than whatever you're comparing it to, it should. Neither are especially soft though. If you use a work mat, the composition of the bench top matters much less. Additionally, with softer materials being less durable, replacing a worn mat is much lower impact than replacing a worn bench top.

    • nevenbekriev- You nailed it with your description of me and my reaction when the clock started ticking again. I am a newbie.  I love the sound and idea of mechanical clocks but the idea of owning one and trying to keep them running has never appealed to me. My wife bought this one and an antique German wall clock.  When I looked into having someone repair them for me, the universal response was "it's really expensive to work on them, you should just replace the movement". So, I had nothing to lose, I started researching them and opened them up. The wife is happy because she hears the sound of the clocks again. But I have gone down the "accuracy" rabbit hole. In the vertical position, the balance wheel was not floating. It was sitting on the bottom of the frame. I adjusted the lower spring collet and got it floating. It easily passed the 270 degree 3 to 5 minute oscillation test. It took 8 minutes for the wheel to completely stop moving.  I put it the unit back in the movement and checked the safety pin. It does not touch the safety roller anywhere in +/-270 degrees rotation from neutral position. But the amplitude of the rotation with the spring fully wound is weak based on what you are saying. It rotates +/-90 degrees from the neutral position.  No, I did not take the movement completely apart.  That seemed way outside my skill set at the time. There is a reason I became an electrical engineer and not a mechanical engineer. I am much more comfortable with moving electrons than tiny moving metal parts. Will I do it in the long run? Anything can happen. I don't seem to be able to let it go.
    • Isn't that the same guy who told Zelenskyy to escalate the war with Russia/Putin when they already had a peace deal? 2 years later and we have half a million young Ukranian boys dead. He doesn't seem very clever...
    • Thanks guys.  quick question. For automatic movement, particularly this one. can I power down the main spring by pushing this rachet down?  i've gotten pretty used to SW210 and powering down a manual movement. But so far i've only been waiting for the auto movement to run out of juice before opening the case.     
    • @Murks the problem you have mate is most watch cases out there to buy are for Seiko NH3X, ETA 2824 and maybe Myota 8XXX movements, oh also the big ETA 6978/9 movements which the dials start around 28.5mm. You might find one on a Google search but I suspect your main chance will be buying cheap quartz ladies watches and hopefully find one of the right size and condition that is acceptable. 😞   Tom
    • The anchor pin should be perpendicular when the anchor is sat on a flat surface and if you post a close up picture of the backplate I will be able to tell you the correct torsion spring , running fast or slow is usually wrong Torsion spring. Here is a video from my YouTube channel showing how I set the beat
