This is not my idea. My grandfather made many for himself and friends. Possibly not his idea either, but as he past it on, so shall I.
It is a good way to organize small bits and pieces and get them high enough to be out of the way but still be seen and accessed.
Step 2: Center Spinny Piece
The center spinny piece works best if it balances out. You could make it 2, 3, 4, 5, 6, 7, 8, whatever sides but I made mine 4 sides. I glued and screwed two two by fours together to make one four by four. Make your center spinny piece long enough to hold as many containers as you like. I mounted the lids to the center spinny piece with two smalish screws per lid. Make sure to leave enough space between the lids to spin the containers to unscrew them from the lids. Also leave enough space at the ends to clear the side pieces so that the center spinny piece can spin, otherwise it would not be a spinny piece. I just used two biggish screws to mount and be the axle of the center spinny piece, I think #10 x 3". One each end. I put one washer on the outside of the side piece, to keep the screw head from pushing into the soft plywood and two washers between the side piece and the center spinny piece to reduce friction. You may want to wait till step four, while you are putting the mounting pieces and side pieces together.
Step 3: Side Pieces
I made my side pieces from half inch thick plywood. Again dimensions are up to you. Make sure that it will hold the center spinny piece and the attached containers far enough from the attachment pieces that it will remain spinny. Making sure the spinny piece stays spinny is important.
Step 4: Mounting Pieces
I used two two by fours cut slightly longer than the center spinny piece, so that once everything is assembled, there would be room for a couple of washers on each end of the center spinny piece to reduce friction. Once I was happy with fit and clearances, I glued and screwed the mounting pieces to the side pieces. Also this is where I mounted the center spinny piece described in step 2. I just used two biggish screws to mount and be the axle of the center spinny piece, I think #10 x 3". One each end. I put one washer on the outside of the side piece, to keep the screw head from pushing into the soft plywood and two washers between the side piece and the center spinny piece to reduce friction.
Step 5: Mount to the Wall/ceiling
Once you are happy that your spinning organizer works, it is time to put it almost out of reach. I found it best to mount on a wall using longish screws thru the mounting pieces into the wall studs. Once again making sure the center spinny piece with containers remains spinny.
Step 6: Use It and Enjoy.
Now it is time to load the containers with all sorts of bits and pieces. Try and balance it out or all the heavy pieces will end up on the bottom. Now when you need something in the spinning almost out of reach organizer all you do is reach up, spin it till the container is on the bottom and unscrew the container.
