Introduction: Kveik - Brewers Yeast Ring
This is a Kviek yeast ring, it is a medieval design used by brewers for the preservation of yeast between brews of beer or mead.
I was asked by a friend who home brews if I could make him one. I started out with a description provided in this article: here
It looks really complicated but really it's a matter of lots of simple shapes forming something complex and beautiful.
Being under lock-down I was restricted to scraps I had on hand, I found a piece of Brazilian Mahogany I had left over from an old chopping board project, it was rough, it was warped but it might just do!
This instructable uses several very dangerous power tools, please be careful in the shop
This instructable is my interpretation of how this could be done, there are many more ways to do this without the tools I have, think outside the box, I'm sure this could be done in at least 10 different ways.
Step 1: Peg Design
The ring is made up of pegs, these consist of a beaked section to the front, a flat section to the rear and a slot to allow them to interlock.
Ideally you will want a multiple of 3, the article called for 70 pegs but I found in the end I needed 72 to close the ring, if you make more the ring will be bigger and easier to work with but may not fit into your brewing pot.
I started out by modelling the design to wrap my head around the processes.
There is also a single flat peg required, again the article refers to this as the final peg but assembly proved that it should be the first peg in the assembly to allow a pull through to close the ring.
Step 2: Material Prep
As I said, I had a nice scrap of Brazilian mahogany but it was in rough shape.
The first step was to mill the piece flat and smooth on the planer (jointer) and see what I was left with.
I calculated from the piece I had left that I would have enough material plus a little for trial and mistakes or which I made many.
The board was cut into 83mm lengths on the mitre saw, this gave me 5 blocks approx 35mm thick.
I then set the fence on my bandsaw to 10mm to resaw the boards to the max peg thickness, this gave me 3 final boards per master blank.
Step 3: Prepare the Rebate for the Tail
I figured that the easiest and most consistent way to produce the rebate for the tails was to cut them before making the individual pegs.
I first set up my crosscut sled and on the table saw and made some test cuts to get the depth to exactly 5mm.
My blade is a flat tooth ripping blade so the bottom of the cut is flat rather than cut with 2 bevels. There are some good videos on youtube about selecting table saw blades for different cuts.
Once I had it dialled in I cut a 5mm deep cut 30mm from the front of the peg, this is the border of the beak and the tail.
I then cut the tail off by standing it up against the fence and making several passes raising the blade until I was removed the waste, this was a hairy process and I would recommend a router or a dado stack here if you have one.
I then separated the pegs at the mitre saw, in retrospect the bandsaw would have been better as the kerf is narrower and I would have gotten more pegs from the stock but the mitre saw was fast.
Step 4: Adding the Slots
I was a bit worried about this step but I set up a simple jig from some plywood.
This allowed me to place the peg in, drill the top hole, slide the peg down, drill the bottom hole and then drill out all of the waste in between.
Sliding the peg back and forth cleans the slot of any little bits of waste left over.
This was laborious but quite fun to see the stack build.
Step 5: Shaping
Using a sharp chisel I knocked off the back corners to remove some sharp edges
I then pared the beak into a rough rounded shape, I wanted to keep the faceted look to maintain the handmade look.
This part is really important as if you don't pare it enough then the ring won't wrap properly.
You could also whittle this part with a knife.
Step 6: Assembly
The assembly starts with the flat peg, then inset the tail of the next peg through the slot in the first peg.
Add the next peg with the beak tops all in the same direction, don't keep rotating, there are only 3 rotations and all of the pegs should be the same was up.
When you have added all of your pegs you can wrap the end of the ring around, this will cause a twist to enter the shape, this is normal as I can tell. Push the first peg (no beak) through the slot on the last peg and tie a string to allow you to hang the ring or to dip it.
The idea is that the ring may be dismantled to be cleaned, it also makes a fun puzzle if you are bored, I remade this at least 5 times during construction and it never failed to frustrate me!
Step 7: Edit
Since I made the first one and then put this 'ible out, I have had LOTS of queries about this and ended up making a bunch more so I posted it on my website and it seems there's a market.
I you want one (as a kit to the USA & Canada or as a kit/built up) you can order one from here
