Still need to cut off the excess axle, went through 6 or more of the cheap c_r_a_p drill bits from HF, ended up buying a single bit from Home Depot for $2 and some change that worked flawlessly-
But the wheels came from HF, and for $4 each you can't beat it. And the drill press clamp came from HF and works just fine as well.
You can see the difference between the new and old wheels in the last pic.

Put the edges of the end of the axles against the grinder, took off any sharp stuff. Came out good, I'm happy with this. Thanks to all before me who paved the way to make something better.
