They'll be super glued in so they should be OK. Right now they're press fit in for testing purposes and it took some effort to get them pressed in so if the testing goes well, I'll run some thin super glue around the edges of the magnets and let them sit overnight. Then I'll put the cover on the gear train and max out the RPMs and see what happens.

Plan B is to 3D print a thin ring that would slip over the magnets as they are now to contain them if necessary. The sensor has a working distance up to 5mm so plenty to work with.

Could you 3D print the entire collar with reverse counter bores? That way you could slip the magnets in from the inside of the collar and they would be held in by the reduced diameter at the O.D.

Thanks! Plan C.

I've been running my big lathe for some years now with the magnets stuck to the spindle without even a spacer. Every now and then, I nudge the odd one back into the right spacing.

I got out of work early today (gotta burn vacation time or lose it), so I went down to the shop to make these:

   

Low profile vise hold-downs.  Made from a piece of scrap square tubing, so I assume hot rolled steel.  Something I've been meaning to make for a while, so this gets them off the list, and frees up a couple of toe clamps in the process.

I like the matte finish.

Ever since I bought that deburring wheel, I use it for everything. Got the tip from Joe Pie.

The welder at work always said, "a grinder and paint, make me the welder I ain't". This is sort of the same thing for machining.

Do you have a link to the deburring wheel?

Do a search for Scotch-Brite wheels. Lots of sizes of wheels and grits available.

In addition to deburring wheels you can get little 1" satin finish buffs that are fixed to a 1/8" shank for use with Dremel type tools and die grinders. Great for a matte finish on small parts or getting into tight areas.
