Introduction: Peppercorn Pepper Mill
Peppercorns! I take whole black peppercorns and turn them into and antique pepper grinder. In the process I get a lesson in the aromatics of vaporizing peppers.
In the end, I feel as though my sinuses are quite thoroughly cleared out, and I have a strong desire to never put pepper on my food. Ever again...
I bought whole peppercorn from the grocery store. I knew I wanted an 8oz blank, so I bought three 3oz bottles. I'm not sure how I missed it, but it was bottled by weight, and not by volume. So each bottle was more than plenty for the casting.
I ended up using my mixing cup as the mold. It was simple and I knew from a past instructable https://www.instructables.com/id/Crayon-Wrapper-Wine-Stopper/ that it was a feasible choice.
I mixed up about 6oz of polyester resin for this project. For the most part, I don't like polyester resin. It's smells awful and it is very brittle while turning, but you can regulate the volume of hardener (catalyst) which allows you to do a deep pour, which would fail with other two part resin. I ended up using 3 drops of hardener per oz or resin (18 drops total)
At this point the only thing I'm worried about is sneezing too much. I have no idea what is in store for me...
24 hours later, I had a fully cured blank ready for turning at the lathe. This is a super simple turning. The start is a 1" hole drilled completely through the blanks. This hole is where the ground pepper will fall through the grinder once assembled. This is the point, when I first got a clue what sort of horror I was in for.
I got the pepper dust on my sleeve and inadvertently wiped it on my face. Then the burning started...
I turned the blank around on my lathe, and began the turning process. This is a simple process of turning a shape for the pepper mill handle, but the turning process took FOREVER. My eyes were watering, my face was burning my nose was running. Chaos. Total chaos. I had totally weaponized my lathe...
I used my carbide turning chisels as the polyester resin is super brittle. Anything other than crazy sharp tools will result in loosing large chunks of the blank.
Once turned. I went it inside, took a shower and worked up my nerve to come back to the shop and finish this project....
Step 3: Sanding & Polishing
I sanded from 120 - 800 grit and then switched over to my micro mesh pads. They start at 1500 grit and graduate up to 12000 grit. Wet sanding was a joy, and my eyes and lungs were so happy to not be assaulted with seasoning.
I love the way the bottom of this blank looks, with the whole peppercorns on the base.
Step 4: Assembly
I ended up giving this 5 coats of spray lacquer to seal in the exposed peppercorns. I didn't show this in the video, as it was already getting longer than I would have liked.
The assembly is easy. 2 wood screws. Load it up with peppercorns, and get grinding!
Thanks for looking!
