Bob,
Those things are available at www.aftosa.com . Look under "accessories" and
then scroll down to "knob hardware". Good luck. (And maybe someone can tell
me, what kind of brackets or whatever do I type on either side of a link to
make it appear "live" in Clayart?)

Hi Bob,
The little things go by the name of threaded inserts. If you've got a
local hardware store that caters to woodworkers they will have them. Here
are some examples -

http://www.woodcraft.com/family.aspx?familyid=1048
They're also available from places like McMaster-Carr and the other big
supply houses. I'm trying to picture the hardware aisle at Home Depot but
can't recall whether they have a small selection amongst the blister packs.
Best regards,
Ralph in NH

Those threaded little thingies that are inserted in the hole are called,
well, threaded inserts.
You can get them at hardware stores, but probably not in a size that would
be appropriate for your cabinet knob. They are a fairly common item for
woodworking, but often the bolt size is larger than you'd want for a
cabinet knob. Here's a link from a google search to a full line of sizes:
https://reidecom.reidtool.com/xephr/edit/ITEM_GROUP?
query=*START_WITH_ID=74511&query=*GROUP_ID=74511&query=*GROUP_PARENT=4015
A couple of thoughts - choose the appropriate bolt size, probably 10-32 or
10-24 thread pan head by 3/8" longer than the thickness of your doors. Then
get the matching inserts. With the inserts in hand, determine the size hole
in the back of the knob that you need to have in the wet clay before the
shrinkage from firing. For example, the 10-x inserts from that source
are .262" outside diameter, and allowing for 15% shrinkage, you'd need a
5/16" hole in the back of the raw knob. The inserts are 3/8" tall, so you'd
need a 7/16" deep hole. Test fire a couple of knobs to see how the insert
will fit in the hole. When you are happy with the fit, make the rest of the
knobs to the same size. When everything is ready, a small gob of epoxy will
hold the insert in the knob and they're done.
A nuance that might make for a better fit and finish at the end is getting
the insert glued into the knob absolutely straight so that the mounting
screw through the door will be perfectly perpendicular to the base of the
knob (and thus the knob will sit straight on the doorfront). For that, you
could make a small jig that has a smaller diameter bolt through a board
such that the diameter of the bolt barely slips into the inside threads of
the insert rather than screwing on. Set the insert over this bolt to keep
it perpendicular to the jig board, put the dap of epoxy in and push the
knob onto the insert until the back of the knob meets the board evenly. Now
the insert is in square to the knob-back, and you can gently lift it
straight up off the jig without wiggling it out of square and set it aside
to dry while you do the next one.
HTH,

Bob:
Not entirely sure what they're called, but a great source for all things
threaded is www.mcfeelys.com. They cater, primarily, to woodworkers and
carry much fastener hardware, screws, threaded inserts, anchors, bolts and
the like. Even if they don't have what you want, get a catalog for some
cheap entertainment...
