We get very focused on the details here at Rejuvenation. From building fixtures with the right size shade holders to providing finished slot-head screws with our exclusive hardware, we like to make sure that we get these things right.
But we also believe in making improvements where we can. When you’ve spent over three decades fixing broken hardware in our salvage department, you can’t help but think of small changes here and there.
A big one is on our door sets.
Most antique doorknobs are threaded. This allows them to screw on to a spindle, which goes through the door, connecting it to the opposite knob and operating the latch. The knob is held on the spindle using a set screw.
Old spindles were squared, and the set screws flat. You had to be careful to tighten the set screw so that the flat of the knob rested on the flat of the spindle. If it rested on the threaded portion, the set screw would wear away at the threads of the spindle and become loose. As you turn the knob, the threads of the spindle and the threads of the knob would wear against each other until the thread inside the knob was destroyed. This is why doorknobs fall off of doors — and why it’s hard to repair that issue once it’s happened.
So we made one small change to our doorset: our set screw is pointed, and the spindle grooved. It’s much easier to positon your set screw in the right place, and it’s much less likely to come loose over time.
Here’s a lovingly rendered diagram I made for a customer:
