Rare Broken 1880s Mortise Lock Set Restoration | Random Restoration

Welcome!
Today I will be restoring an old rare broken ornate mortise lock set manufactured by Lockwood Manufacturing Co. between the mid 1880s until the 1890s. No surprise, another hardware restoration video haha. This design is (unofficially) called the Lockwood Broken Leaf - this is very fitting since it was indeed broken due to abuse. Much like in my previous mortise lock restoration videos I started this project by disassembling the mortise lock. Although the interior of this lock was filthy with years worth of old grease and other lubricants, it was obviously going to be much less of a rusty restoration in comparison to many of my previous restoration videos.

After the mortise lock was disassembled, I found a broken post inside the case which was meant to keep the lock bolt in place. Good thing I'm pretty familiar with door hardware and this isn't my first mortise lock repair! Anyways, I moved onto the paint removal stage. I had to apply two separate coats of paint stripper to remove most of the original paint. Then I gave all of the parts a thorough clean with some degreaser to remove all of the years of filth they'd accumulated. The next step of the restoration was the rust removal stage, and like usual I submerged the parts in Evapo-Rust for a few days.

While waiting for that I went ahead and searched through the 1894 Lockwood catalog, where I found the "Broken Leaf" design in multiple locations through the catalog. Once all the parts had been removed from the rust remover I went ahead and abrasive buffed all of the parts, followed by thoroughly going over them with a wire wheel, making sure to get into every nook and cranny. Then it was time for key cutting. I swear I'll be a professional locksmith if I keep all these restoration videos coming haha.

Then I had to figure out how to repair the lock case. My DIY lock repair consisted of a stainless steel bolt, threaded through the case and thoroughly sanded down to make the lock bolt fit like new. With how it's fitted it is impossible to unscrew itself, and should work for many decades of use! After the mortise lock was repaired, I moved onto sanding and polishing all of the bronze parts. Then I switched over to painting all of the large components. I painted the recessed areas of the ornate bronze parts, which is what finish #3 in the 1894 Lockwood catalog describes.

Next up I had to restore the small parts. I went ahead and did some nickel plating on a handful of parts. I sanded and polished all of the remaining brass and bronze parts. I then did cold bluing with the remaining small parts. Bluing steel is always a weirdly satisfying thing to watch IMO. The parts were all then reassembled. I installed them in a piece of wood that I drilled and chiseled out. Then I gave it a proper test, and not only is this a beautiful lock, it works great now! Of all my restorations this one is by far my favorite outcome - It's a truly gorgeous design, and along with a near perfect restoration is such a joy to look at.
