Refurbishing Old Points

[lindy46]

After so much frustration with the quality of the points they’re now selling, I decided to spend the afternoon refurbishing old points. I had lots of them around so I picked the best of them and cleaned them up, ground them smooth and polished them up. So I now have enough sets for 4 motors. No more junk to deal with.

Can you explain what you did exactly?

I also have lots of old points and would love to be able to reuse those

I picked those with good rub bars and little pitting on the point surfaces. I cleaned and degreased them with some mineral spirits and used a fine wire brush to polish up the flat metal surfaces. I tried a Dremel to treat the point surfaces but that didn’t work too well.  So I got out my point files and ground them by hand. Had to make sure to keep the file flat on the surfaces. Just filed gently until they were smooth and flat. I tried not to take them down too much. I finished by using some fine sand paper. And then a final clean up with mineral spirits. I temporarily mounted them on a mag plate to make sure they lined up properly. I’m confident that these will work out much better than the new ones available today.

Lindy46,      You might try using a fine sharpening stone like one used to sharpen fishing hooks.  Some of the surplus stores sell small flat stones about 3/8″ wide by 3 – 4″ long !

Good idea.  I’ve got one of those somewhere in my tool chest. Just need to find it.

what I have used is a fine diamond hone. I have one that is about the size of a narrow popsicle stick. It takes high spots down real quick and leaves a fine finish. No fear of residual aluminum oxide grit imbedded in/on the point surface.

A very successful method I use, is to use cut strips of fine wet and dry sandpaper and support the paper along the length of the file……..gets a great mirror finish.

Has anyone successfully replaced a worn out rub bar?
