I have some old mortise locks in my 1920 house, some probably original, One has a fancy B logo on the side, others have no manufacturer indicated. All seem to have the same basic structure for the spindle (threaded) on which the knobs fasten The spindle goes through the latch mechanism on a 45 degree angle, i.e. diagonally. However (without knowing this) I purchased some lovely Victorian style lever handles to replace a couple of old doorknobs that don't work properly or are the cheap ugly glass types you can buy anywhere. These nice lever handles would work fine with my old spindles and locks except they have been designed so that the spindle threads through the latch mechanism as a straight horizontal square, so that the levers will be either angled up or down when fitted on the spindle and the back plates angle at a 45 also. Bummer! Today while buying paint at HD I noticed a mortise lock mechanism for sale that had a star-shaped spindle hole in the latch mechanism, which means one could use either spindle type. However I'd rather not replace all the locks as most of them work perfectly well, I'd just like to replace the little machined part (I can't figure out what it is called, which is annoying) with one with those nifty star-shaped holes.
A) What is the name of the part? I have taken the lock apart and looked at pictures but no one online seems to label the lock parts.
B) Are these available for sale or do I have to go to my friendly local machine shop and have them drill the part out for me?
Thanks for any info you may be able to share!
Answer Hello Margaret,
Unfortunately it's unlikely you can replace the hub (the part that accepts the spindle) with one that allows for diagonal installation. Manufacturers design their locks a certain way and each one uses a different style of hub.
Before you pay your machine shop to modify the hubs, check with www.charleslocksmith.com to see if they can help. They deal in old locks and may be able to help.
I do not answer Safe or automotive questions. Period. I am knowledgeable in almost every area of Locksmithing. This includes locks, keys, lost keys, residential and commercial lockouts, rekeying, masterkeying, high security locks, access control, electric locks, security cameras and home safety. I have been running an online business since 2004 where I sell all types of lock and security hardware to everyone from apartment renters to business owners to the US government. Before that I started a locksmith service in 1999. I deal with many types of security equipment including high security safe locks, heavy duty padlocks, exit devices, biometric readers, electric strikes, magnetic locks, full surface hinges and I only sell what I personally stand behind 100%. The online business has given me a more in-depth look at the locksmithing industry, helping me to learn more about each and every product that I offer, as well as products I don't have but end up finding for customers to solve any issues they have with security or door hardware.
Please don't submit any automotive or safe questions as these aren't areas that I can help in.
