In Reply to: RE: Macro Photos of My Stylus and Cantilever: Damaged? posted by joeychitwood on February 25, 2015 at 18:42:27
I suspect the others are correct that the stylus is still okay, but you should probably look at it from the front at higher magnification to see if there is significant V-shaped wear. Also look straight down at the tip with side lighting to see if flat spots are visible. I suspect that 48-hours in a spinning groove would not have caused a problem, but you never know until you view it at the correct angles.
Here are some pictures of a stylus that is too worn to continue playing LPs without causing groove damage.

What magnification are you using there, 150x, 200x?Many years ago (okay, well over 20 now) I was allowed the use of my audio guru/friend's stereo microscope and got to see the difference between good and bad styli of different shapes- but I'll be darned if I can remember the level of mag he had it set on!

I think it was 200X. I used a microscope with a third ocular for the camera.
Actually, that microscope should be more than sufficient. However, you need dual fiber-optic lights to aim directly at the playing surfaces. You judge by the shape, size and clarity of the playing surface. It is best to have a new stylus to compare, which we always had in the store.
I have the right microscope, but I have yet to buy the lighting. It is expensive.

I actually bought the correct dual fiber optic light, but I have yet to take a picture of it. Yes, it was an expensive light and I hardly ever use the microscope anymore.
When I originally bought the microscope, I thought it would work as is because its built-light shines down through the objective lens. However it wasn't bright enough to light a stylus properly. I used flashlights for a while before finally giving in and buying a dual fiber optic light.

...when funds permit (gotta get a new power amp first. Darned priorities)!

Dman, I used my Nikon DSLR with a Nikkor 105mm Macro lens to take the photos. I will try some of the angles suggested by John Elison this morning in brighter light outside. (Once the temp rises, as it is -19 degrees F now.)Regarding the "time out" phrase, perhaps that was incorrect. I was referring to the suggestion by most manufacturers that their cartridge will last 1000 hours, or in the case of Benz, up to 2500 hours. Just wondering if the coils and magnets are the parts that wear out.

Magnets and coils should not wear out under normal use. Abuse (banging or dropping the cart) is a whole other animal, and all bets are off!
The time listed usually refers to stylus life (and again, if you abuse it, figure a lot less time)...
Now if you want to get into whether or not you should be demagnetizing...
Cheers,
