Many clocks run just fine without lubrication, but sometimes they stop for no apparent reason. The thread Silk PLA issues | Steve's Clocks (stevesclocks.com) describes the issue. I have been using lithium grease because it stays in place. A very small drop of oil applied to the pinion teeth with the tip of a toothpick might be just as effective.
if I had to do a 15 day rutin, I would have to use a weight of 5 kg, I will have to add another 2.5 kg of weight but I would have to use more lead, because the bb shots are too light ...., what did you use in your watches? , because I saw that you used the largest container with only one extension as I used, but I did not reach the weight I needed with the BB pellets.
The weight filler needs to be a relatively dense metal. Copper, iron, or lead are common choices. I use BBs with a steel core and copper plating. They are the traditional BBs that have been used by kids for over 100 years.
Airsoft guns may also label their small plastic pellets as BBs, but they are way too light to be useful.
for the weight, I am using a weight of 2.5 kg, with BB pellets I could not have a weight of 2.5 kg because they are too light and the container was needed too long, I printed the container for the Mini prusa version and I added an extension, I filled with BB shots, but the weight was only 750 grams, so I had to melt some lead I had and I made some cylindrical lead weights to put inside the container, I managed to have 2.5 kg with the largest weight and with only 1 extension.
Hi Steve, I have some questions to ask you, first of all I want to congratulate you on the beautiful project you have done and it works very well ... .., the clock is running one day and I am adjusting the pendulum because the watch is more accurate. the first question: how can I increase the Tic Tac noise?, second question, right now I have the 7 days rutin with a weight of 2.5 kg, the clock is fine, in your opinion should I decrease the weight or can I leave it like this and if you ever print the 15 day rutin?, third question, would you recommend that I lubricate the gears with Wd-40 oil?, last question, the pendulum rod is connected to a threaded pin that you call gear 0 , it can be moved forward or backward, I have positioned it in the center as you indicated in the instructions, I wanted to ask you what is the use of moving it forward or backward. A thousand thanks.
The noise will get louder with more drive weight. The larger versions of my clocks with larger escapements will also be louder. Switching to a 15 day runtime with the same size drive weight will give less energy per tick, so it would make the clock quieter. Doubling the drive weight would keep the clock approximately the same volume.
Traditional WD-40 would make a really bad lubricant. It penetrates rusty bolts and provides some lubrication until the solvent evaporates, then it leaves a sticky mess that makes the clock run worse. There may be other lubricants under the WD-40 brand name, but I would stay away from them. I have been using white lithium grease on the pinions and the clock has been running for several months. I added some food coloring to help match the color of the gears.
The spiral notch on the pallet shaft can be used to adjust the angle of the pendulum shaft relative to the pallet arms. It only works if you use both mounting screws to hang the clock on the wall. If you use a single mounting screw, then it is easier to just tilt the clock frame slightly to adjust the beat. You may need to re-adjust the beat if the clock position shifts when winding.
what weight do you recommend to print to contain 2.8 kg?, in the prusa mini I saw that I can only print the 2p4 version with extension, is that enough?, I tried to print but then I stopped because it seemed to me a small diameter to contain 2.8 kg of material, which model do you recommend to print?. A thousand thanks.
@Massimiliano Molinari A half height top portion plus extensions is like the full sized weight shell. It loses a tiny bit of interior volume, but you can always add more extensions if needed.
Hi Steve, I did the weight test as per your indication in the video, I saw that the watch runs well with a weight of 710 grams, to make the watch go do I have to increase the weight four times? final of 2.8 kg?. A thousand thanks.
ok for the fat,
i will search on amazon for a lithium grease,
I wanted to ask you if I do not use grease and do not give anything, could the watch have problems over time?.
Thank you so much for the great job you have and are doing !!
