This can be simple. The function of the rose is to supply a bearing for the
knob spindle. Usually the rose is secured to the door so that the spindle
stays in line with the lock.

If the rose you are considering just has a little smaller hole than the
knob, then the only thing that needs to be done is to either reduce the size
of the knob spindle, or increase the size of the hole, or a little of each.
The choice is made by how much material will be left when the machining is
done, or which piece is easier to machine.

I would take a sample of the knob and the new and old rose to a machine shop
or two and ask them. This should be no problem.

Please forgive me if I'm posting in the wrong group, using the wrong
vocabulary, or asking questions that have been asked before -- I'm
really know very little about this and I researched as best I could
before asking!

We are restoring our apartment, and we decided to keep our vintage glass
doorknobs. Unfortunately, the roses (the metal donut which the knob sits
in -- do I have the name correct?) that we have are flimsy and cruddy
looking. We tried to buy new roses from Rejuvenation Hardware, and found
some nice ones, but the opening is too small to accomodate the doorknobs
-- the opening is 5/8 inch, whereas the original roses have an opening
of 11/16 inch.

My question is, what our our options? Is it possible to find roses with
the larger opening anywhere, and if so where? (I guess salvage stores
are one place to look, but we've tried every store in New York...)
Another option we were considering was having the ones that we have
cleaned up and refinished, but it would be nice to get new ones...

Second question: we need new keyhole covers for the keyholes in the
mortise locks. The keyholes won't actually be used but they're part of
the look, of course. Is there a good place online (or elsewhere) to look
for these?

Thanks much for any help.
