Can I Use Antique Door Knobs on a Modern Door? Yes, You Can!

[@suziemannara6032]

A very good start to understand the intricacies of old door knobs. I like the fact that you gave the correct names of the various pieces of the hardware.

You are very welcome...just happy to help clarify the process and promote the reuse of old American door hardware!

Can I get a key for an old door know? Like what you showed from the 40's? I need to lick the door. Also, how can I get it to turn upside down?

This is wonderful! I’m seeing knobs with different size/ length spindles. Hoping you can do a video on how to tell how to tell the difference and what spindles would fit what. Also do you know any manufacturers who make jigs for old mortise and tenons?

Back in the old days of hardware, there were a lot of different manufacturers and styles and sizes. Spindles lengths and sizes varied by manufacturer and even within the manufacturer's range. Lengths were very different and do depend also on the thickness of the door being used as well as the type and size of door plates or rosette. On threaded spindles, there are also multiple thread sizes. In reality you have t have the spindles and knobs together to make sure you get the right fit... Same with latches/locks....ugh! Don't know of any jigs and there again, mortise locks were available in hundreds of styles and sizes....sorry!

I have antique crystal doorknobs from the early 1930s that were used in the original interior doors throughout my home with mortise locks. They are fitted with threaded spindles. I also have all the mortise locks, face plates, etc. My new doors don't have any knob holes drilled yet. I want to use the knobs. I've been told that my current doors are too thin to use the mortises (5/8" mortice, 1-1/4" door). Do you know where I can get the necessary tube latches?

[@knobsandhandles]

Hi Susan! You will need ones that hold 9/32" spindles. On line shops like Van Dykes (restoration hardware) will have them!

I bought some cast iron back plates. I would like to paint them matte black. What paint would you suggest?

[@knobsandhandles]

Well, first I would use a Satin finish, not flat. If you paint it and you need it a little flatter then take some #0000 steel wool to it. Krylon is a good brand. Thanks for asking! Scott
