HOW TO CONSTRUCT A DODEC SPINNING WHEEL Jennifer Wagner LIS 7963 July 30, 2014 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 Materials: (2) ¼-20UNC x 3½ full thread, hex-head bolts (1) ¼-20UNC x 3" full thread, hex-head bolt ( 2 ) 1 " x ¼ " fe n d e r wa s h e r s ( 3 ) ½ " x ¼ " wa s h e r s (1) 3/8" nut (6) ¼-20UNC nuts (2) ¼-20UNC lock nuts ( 1 ) d owe l ¼ " x 1 2 " ( 1 ) s h a ke r p e g s ( ½ " x 17 ⁄ 3 2 " te n o n ) ( 1 ) 1 " x 4 " x 10 ' p i n e b o a r d ( I p u r c h a s e d 1 2 fe e t ) (1) hinge (1) ball of butcher’s twine (1) box of 18 gauge 1¼" brads Re g u l a r o l ’ h a m m e r a n d n a i l s P a r a f fi n wa x ( n ot g r e a s e o r o i l ) Wo o d g l u e To o l s : C i r c u l a r s aw ( p o s s i b l e w i t h h a n d s aw, b u t n ot p r e fe r a b l e ) Hand drill D r i l l b i t s i n s i z e s 17 ⁄ 6 4 " a n d 9 ⁄ 3 2 " ( M o s t p e o p l e w i l l h av e to b u y t h e s e ; c o m m o n b i t s e t s o n l y g o u p to ¼ " ) Hammer Sandpaper (This wheel will work rough c u t , b u t m o s t p e o p l e w i l l w a n t to s a n d it) P r ot r a c t o r 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 B o r r owe d a f r i e n d ’s t a b l e s aw ( w i t h a laser!) and cut m o s t o f my wood pieces. S o m e p i e c es are small and f i n g e r s c o ul d be lost when using a table s aw. I s av e d those pieces f o r l a te r. TEN FEET OF LUMBER IS ALL IT TAKES W h e n yo u t h i n k a b o u t i t , te n f e et o f l u m b e r isn’t all that m u c h . I f yo u know someone with a work s h o p , t h ey m ay h av e p i e c e s o f 1 x 4 t h a t yo u can use. O t h e r w is e , te n f e et o f p i n e i s about $8 at H o m e D e p ot . LABEL THE PIECES M a ke s u r e to label the pieces. It would be zero f u n to t r y to f i g ur e o u t w h a t yo u h av e l a te r o n i f yo u c a n ’ t b u i l d yo u r wheel i m m e d ia tel y. INGENUIT Y IS IMPORTANT W h e n yo u r w o o d g l ue i s t h e c o n s i s ten c y of peanut b u t te r a n d won’t come out of the bottle on its own (and yo u d o n ’ t w a n t to b u y a n ew bottle), a little c r e a t i v i t y to g et i t o u t . THERE IS NOTHING WRONG WITH OLDFASHIONED Don’t own a p n e u m a t ic n a i l gun? No need to g o o u t a n d b u y o n e ( p l us a compressor). A good ol’ hammer and nails works just fine for this project. CONSTRUCT THE BASE Glue and nail the pieces for the base (that yo u l a b e l ed , o f course). POWER DRILL: ESSENTIAL & BEAUTIFUL Po w e r d r i l ls m a ke d r i l l in g the necessary holes in the wheel assembly s o m u c h e a s i e r. N o n e e d to g o o l d - f a s hi o n e d h e r e . I f yo u d o n ’ t h av e o n e , yo u p r o b a b ly know someone who does. MAKING ANGLES I ’ m a l i t t le e m b a r r a s s e d to admit that I do n o t h av e a p r o t r ac to r i n my h o m e . A t all. It helped that we had a 3 D p r i n te r i n t h e c l a s s r o o m. 3 0 m i n ute s l a te r a n d p r o bl em solved. WHEEL: ASSEMBLE! U s i n g yo u r handy dandy p r o t r ac to r, measure 30 degree angles on the pieces of the wheel in 3-piece sections. AN ALMOST PERFECT CIRCLE Arrange the 4, 3-piece s e c t i o n s i n to a c i rc l e , maneuvering t h e m i n to a n ev e n - a s p o s s i b le c i rc l e . BRACING Attach the wheel braces, a s c e n te r e d a s p o s s i b le . SANDING DOWN THE STEM T h e s te m o f t h e w h e e l n e e d s to f i t s n u g g l y i n to the base. I n i t i a l ly, my f i t was so snug, that the wood was creaking and groaning a s I t r i e d to w e d g e t h e s te m i n to t h e b a s e . Rather than b r e a k a ny t h i n g , I sanded the b o t to m o f t h e s te m to m a ke t h e s te m s l i d e i n to t h e b a s e s n u g , w i t h o ut cracking the wood. IT’S COMING TOGETHER T h e s te m i n t h e base with some S t a r b uc k s to help me power t h r o ug h t h e c o n s t r uc t i o n process. HOUSTON, WE HAVE A PROBLEM… T h e s te m a n d the upper receiver pieces n e e d to h av e hole that align. I thought it was a b r i l l ia n t i d e a to g l u e t h e p i e c e s to g et h e r w i t h a to uc h o f w o o d g l ue , d r i l l the holes, and s e p a r a te t h e pieces. It h e l p s i f yo u a c t u al l y r e m e m be r to s e p a r a te t h e pieces. Even a little wood glue can go a long w ay. WHEN ONE ISN’T ENOUGH I n s te a d o f o n e p u t t y k n i f e to pry off the u p p e r r e c e i ve r, l et ’ s t r y f o u r … EIGHT IS ENOUGH? Added some t a b l e k n i v e s to the equation. T h ey d i d n ’ t help a whole lot. ATTACHING THE HINGE I te m p o r a r i l y g av e u p o n my u p p e r r e c e i ve r p r o b l em ( n ex t s te p : h a n d s aw ) a n d i n s te a d attached the h i n g e to t h e treadle and the base.
