Fairly easy to make this one. All you need is a router or jigsaw to cut the circles, a saw to cut the different lengths for the centre pole, a drill, a hacksaw, allen keys and sandpaper. I used 12mm ply for the shelves, an old coppers log for the center pole (although ive now made another stand using 75x75mm DAR pine for the pole), 4x wooden drawer knobs for feet on the bottom shelf, M8 wing nuts, an M8 washer,
M8 threaded inserts and threaded bar to join it all together.
Once you've decided the size and how many tiers you want, how tall the shelf will be and how far apart each section will be you can go ahead and cut out the circles and cut your center pole lengths. At each end of the center sections you'll need to drill a 9mm hole in the center (Drill the holes a little deeper than the insert will reach) and screw in the threaded inserts using an Allen key. Cut some short lengths of m8 threaded bar just long enough to screw fully into the insert plus the thickness of the shelf and enough to screw into the next pole section. Drill an 8-9mm hole in the centre of each circle.
Starting with the bottom shelf, screw in the 4 wooden knobs at 12, 3, 6 and 9 oclock positions on the bottom side. Screw one of the cut m8 lengths into one end of the bottom center pole. Place the protruding end of the stud through the hole on the top side of the bottom circle. From the bottom side add the m8 washer and wingnut and tighten. ( i added an extra piece of ply between the bottom side of the shelf and the washer to give the base a bit more strength) Now with the base standing on its feet you can keep adding the threaded studs, a shelf then screw down the next center pole section until you reach the top. You can use a wingnut to secure the top shelf down. Or for a neater appearance don't install the threaded inserts into the top end and secure the top shelf to the center pole with a counter sunk head wood screw like I did.
This type of assembly makes the shelf versatile as it can easily be dis-assembled for storage or you can mix and match or add or take away shelves to change the height.
That's a nifty tiered display unit you've created there. Do you have any particular plans for what it will be used for?
Many thanks for sharing your project and providing detailed instructions so members can build one themselves.
One of the shelves is being used in a Christmas window display at a local furniture sales business. My daughter is putting the other one to use at home instead of using a Christmas tree. Start of a new tradition.
