Why make this?
My grandfather's peppergun broke, so he asked me if I could fix it or buy him a replacement. He's been using it for over 30 years. So I looked online on the official website (http://www.unicornmills.org/faqs.html) and the peppergun was discontinued. So I checked ebay and to my surprise it was $100. So I decided to open it up and make the broken part and put it back together for him.
He was ecstatic. :)
Assembly
Assembly is somewhat straightforward. Once you open the top of the peppergun (yes it will take some force, and yes you will have to glue a part in place to keep it closed again) you should see at the top a tension spring and a locking ring. Both parts are included here.
- Disassemble peppergun by pulling the top piece off. This should expose the grinder's main shaft it was mounted on.
- Remove the broken spring cam.
- Remove locking plastic piece for the shaft to grinder component.
- This is also provided as the original one was slightly tighter than the printed one which this makes the printed one a looser fit and better performant.
- Replace broken spring cam (it's the part at the top that the shaft fits through)
- Break and grind off any remaining plastic from the previous spring cam, you are replacing that whole part.
- Glue the spring cam back to the edges of the peppergun so it sits in place. The original glue gave way after 30 years. I printed my part in PLA so I used CA glue for this.
- Add spring back. This step is extremely finicky and a huge pain.
- NOTE: The spring legs need to be squeezed past each other and then inserted onto the cam.
- One of the legs should be locked in place by the cylinder found on the printed cam.
- The other leg will need to be inserted behind the top as you are assembling the peppergun.
- Once the top is reassembled, it should be pressure held onto the grind shaft that runs through the center of the device.
Note: I would add pictures here but it's already reassembled and I really don't want to go through that again. This is an integral part of the peppergun, but also the most heavily taxed piece through use.
