I'd like to remove two snaprings from an old Hein Werner model K
floor jack. They're pictured at

and

None of the tools in my collection has any chance of
holding on to these things. Does anybody know of a tool
that will get them off?

It's likely possible to use a Dremel tool to notch them
so they can be either grabbed or broken, but that promises
to be a lot of work and somewhat hard on the adjacent metal.
Better ideas would be much appreciated, I don't like any of mine.

Thanks for looking, and any guidance!

It looks to me like you could grind a tool like a flat blade
screwdriver to either fit the space snugly or wedge it in, and twist
it sideways to expand the ring. I have a bundle of 3/16" steel gas/TIG
welding rod that I forge and grind such custom tools out of. I make a
round or tee loop on the handle end. The rod breaks without bending if
notched half way with a cold chisel or hardy.

I recently found that the shield retaining snap ring on a 608 ZZ ball
bearing is beveled =/ /= on the ends and a safety pin point will lift
out the undercut end to clean the bearing or swap in a rubber seal.
