    If your file size is too large, you can't upload it here. Reduce the size to 800 pixels in the longest dimension. See this thread for some helps. Lots more info and file resizing apps are available on the web. Do a search and you can find them. FYI Marketplace rules are here.

    This bearing was cleaned and spun by the shop maintenance man/machinist. Pronounced as good, no need to replace it. I had done vibration sampling and found it to be 'noisy'. Had the print out to show it. Took the bearing away from him and cut it with an angle grinder. This is what it looked like. I had run vibration tests on the machine because it was literally screaming at 5000 RPM. So don't trust that cleaning and spinning a bearing is an adequate measure of its health. Bearing on the opposite end of the shaft was the main culprit, but once you have the machine apart, replace the $10 bearing and save another 18 hours work in tear down and repair. Bearing in the 2nd photo was causing the shaft to jamb during attempted startup, so he put a pipe wrench on the shaft to loosen it up. A real no-no! Half deaf so he didn't notice the machine screaming. This was in a steam turbine lab in a technical school. I could hear it from out in the hallway with the door closed.

    Rudimentary stethoscope, works very well. Have used it in many cases, machinery in power and process plants, automotives, etc. Works so well I bought a stethoscope (mechanical, not medical) and have used it a few times. Screw driver is usually closer at hand so I often use it instead of going back to get the stethoscope. A stethoscope helped me find a cracked/broken wrist pin in a old style Dodge 318 V-8. Top side of the engine, noise was on front cylinder on right bank, on the bottom it was on the 3rd cylinder. Cracked wrist pin was on the 2nd cylinder directly between the two measurement locations. Replaced piston, wrist pin, rings, rod and gaskets, and was back on the road for about $80 in parts.

    But you get the same sound whether it is driving the machine or not, so that would appear to be a misleader. Check with the seller/manufacturer about the noise the motor makes. Exchange it for another, same model and see if it makes the same noise.

    I've tried a few different spray bottles for misting leather as I'm tooling it. Can't get a nice even spray, not atomizing well enough.

    You need to provide pictures and full information about the condition of your machine. See the marketplace rules and comply.

    @Hidden It sounds like electrical switching noise being amplified by the motor housing. Sort of like a stepper motor/actuator which are a type of servo. Some cordless drills sound similar, usually just not as loud.

    When part of the project is sewn as part of the assembly, I always sew around the single layer edges as well. I believe all the edges should match, whether single or multiple layers. Skipping single layer edges make the project seem incomplete.

    Moved your post to leather sewing machines. This is where the sewing machine guys hang out and you are most likely to find the answers you are looking for.

    Please post your photos on this site. 3rd party hosted photos get lost, then the thread becomes useless. Host changes policies, owner moves or deletes the file off the host, etc. If photo files are too large, then reduce their size to 800 x 600 pixels. High res photos don't display on phones and monitors in high res. Smaller files download more quickly for people on the fringes of the internet instead of taking 10 minutes or more.

    Moved your post to the Marketplace. Please read the marketplace rules as was stated above and comply. You will find several sub forums under the marketplace, I stuck yours under sewing machines. Typically it would be better to place a post for each machine in their related topic area. The home screen shows all the forums. Go take a look. https://leatherworker.net/forum/ You need to reduce the file sizes. See this thread for some helps and suggestions. There are many more helps and apps on the web that you can also refer to.

    What kind of sewing is he wanting to do? Makes a huge difference in the type of machine you need. See this thread.
