Steps 1-4 : Barrel Tumbling
The barrel tumbling process works like sea glass. The frames spend four days (one day in each barrel) to remove tool marks from when they are cut, soften sharp corners and add a high quality finish to the acetate.
Step 5 : Sanding
The frames then move through several more steps and are then assembled. We craft every pair to make a seamless connection between the front and the temples. The first step in this process is to gently flatten the connection through sanding.
Step 6 : Hand Filing
After we get the connection close on the sanding belt, we hand file every pair to make sure that the connection is perfectly flush. Here at Lowercase, we consider this a true sign of quality and craftsmanship.
Steps 7 + 8 : Felt Buffing Wheels
We use two different felt buffing wheels to smooth out the connection that was filed and remove any filing marks or burrs. First we use an aggressive wheel, then a more gentle wheel to smooth out the acetate.
Steps 9 + 10 : Polishing Wheels
After the connection is crafted, the frames move on to receiving their final polish. We use a two step process - first to smooth out any minor scratches or imperfections on the frame, and then a final polish to give the frames a solid shine.
After the final polish, the frames are ready to be fit with lenses, wiped down, and shipped off to you!
