Doors – Can’t remove Schlage knob

If you're in an area with older homes, try your local locksmith.

The last time I had to replace a split spindle (where the split was not in the middle), the local lockmith had 'em in steel and brass. I went with the brass, because I had to grind out a channel so it'd fit into the existing mechanism; you might have to do similar and drill it yourself.

The ones you see online probably aren't a press fit -- most of my knobs take a set screw.

You can also try a real hardware store (not a Lowes or Home Depot ... either an independant one, or an Ace, True Value, etc.)

If you strike out completely, I've also replaced the whole knob and spindle with a replacement set, and switched to a threaded spindle. It looks like Van Dykes has a few :

It looks like what you're looking for is referred to as a 'drilled spindle' (possibly drilled & tapped, if there's threading inside the holes)

Using the search "drilled door spindle", I've managed to find a shop in the UK:

... but many of the hits talk about pre-drilled doors, rather than specificall drilled spindles.

i used a piece of plywood clamped to the door as an outer-guide. Cut a hole in the plywood, the right size (2 1/8) and then clamp it where you want the new hole in the door. Then using it as a guide on the outside of the hole saw, drill on through the door. voila. no additional tools required beyond the 2 1/8 hole saw, and well, a c-clamp which you should have.
