HOW TO CONSTRUCT A
DODEC SPINNING
WHEEL

NOTES ABOUT THE INSTRUCTIONS
 The instructions I found and followed are available online.
They are available through Spinning Daily’s website
(http://www.spinningdaily.com/media/p/ 9016.aspx).
 The instructions that follow are mostly a simplified version of
those on Spinning Daily with some advice on how to make it
even simpler and cheaper for anyone who may want to
construct one for themselves.
WHY?
 Why a spinning wheel?
 I am a knitter and a spinner. Currently, I spin only on spindles and it
takes quite a long time to spin up a skein of yarn on a little spindle.
 Commercial spinning wheels, however, usually cost $300 on up, even
for a used one. I do plan to purchase a wheel someday, but for about
$40 or so, I was able to construct a simple wheel to give learning to
spin on a wheel a try without the big investment.
 Dodec?
 Short for Dodecahedron – a shape with 12 sides. The wheel part of
the spinning wheel is made out of 12 small pieces of wood.
MATERIALS AND TOOLS

NOTES ON CONSTRUCTION
 Look over the supply list and see what you may have in your
home, workshop, or items your friends may have that would
meet the criteria for constructing the wheel.
 For example, the design I used called for brad nails. In our
ignorance, we bought a box of brad nails, not realizing that they
require a nail gun. We do not have a nail gun. And the size of the
brads was odd, so finding a non-pneumatic nail gun was difficult.
 Odd sizes became a thing while I was building this wheel.
 The bolt sizes were odd; the drill bits in the plans were not in our drill
bit kit; a fender washer the design called for proved impossible to
find unless I wanted to order a huge box of them.
 If I had to do this again, I would consult some of my engineering friends or
sat down and mathed it out myself to make it easier and less expensive.
REMEMBER THIS DURING CONSTRUCTION
From the original instructions:
“Having said that, the drilling of this
hole is like everything else in this
project: poor craftsmanship won’t
keep the wheel from working.”
MEASURE
T WICE,
CUT ONCE

WITH OLDFASHIONED
Don’t own a

to g o o u t a n d

good ol’
hammer and

fine for this
