How to build a turntable for reconing subwoofers

Materials: Round piece of wood - You can use leftover MDF or Plywood from the woofer cutouts in your enclosures! We recommend using something that’s about 8” in diameter and ¾” thick Short Low-Profile Screws Fastens the lazy susan to the wooden base. Choose a screw length that is shorter than the thickness of your material. Rubber feet bumper centers the subwoofer on the turntable. Use appropriate size to fit in the back of your woofer- http://sndqbd.com/2 Box carpet, EVA craft foam, Craft Felt, or a Sheet of cork - Top of the turntable. Craft foam - 6mm craft foam - http://sndqbd.com/3 3 Pack of Lazy Susans - 2, 3, 4 inch http://sndqbd.com/4 6 Inch Lazy Susan - 3,4, 6, & 12 inch available http://sndqbd.com/5 Weather Stripping, craft foam, or pieces of your last surround make great “feet” for the corners of the lazy susan to keep it from slipping around. If you’re reconing a woofer, then you will probably have pieces of an old surround. Tools: Drill or Screwdriver Saw or Router Measuring Tape Sandpaper Pencil Razor or Utility Knife Instructions: If you’re using an uncut piece of wood you’ll need to measure out your center and your cuts. If you’re using a recycled piece of wood from an enclosure cut out that already has a center pin hole, you might not need a few of these steps. We’re going to cut out an 8 inch diameter circle so to make that easier, I’m going to start with a 10 inch square of wood. Just so I have a little bit of room to grab onto. Once my square is cut out I’m going to find the center of it. So I measure 5 inches in each direction and draw some lines. The lazy susan I’m using is 4 inches across so I’m going to measure and draw guides for where it should sit. I place the lazy susan where I drew the guide lines to make sure it matches up. Also, you may mark where to drill pilot holes for your screws. I’m making all of my measurements and guide lines before I cut out a circle because it’s much easier with straight cut edges as reference points rather than trying to measure from the edge of a circle. Once I have my center, I’m going to drill a hole. If you’re going to cut out the wood platter with a router, be sure to drill a hole that is the correct size for your router’s guide pin. If you’re going to use a jigsaw, you’ll need this hole in a later step, so just do what I say, and drill it. You can also drill pilot holes for your turntable screws as well. Using a scrap piece of wood, a nail, and a pencil I make a makeshift compass. Measure halfway across the width of your wood and draw a line. Now draw a line perpendicular to the last. This is where your nail will go. Now measure 1 ½” down the line and mark it. This is where your pencil will go. Drill a hole for your nail, and a hole for your pencil. Insert the nail into the board. Place the nail end into the center hole of the turntable and insert your pencil into the other end. Trace a circle around your wooden plank. Now using a saw or router, cut out the circle. Once the circle is cut out, smooth out the edges with some sand paper and then mount the lazy susan to the wooden platform. Now, turn the turntable upside down. Cut out little squares from your scrap surround and glue them to the bottom side of the lazy susan. This will prevent the turn table from sliding around your work surface. Flip the turn table back over. Now we’re going to coat the top with a padded surface to protect our motor from scratches. Get your glue ready, start spinning the turntable and apply some glue. Keep spinning it and spread the glue around to cover the surface area. You may also use contact adhesive if you like. Next, place your chosen material onto the top of the platform. Once the glue dries, trim away any excess material from the edges. Finally, mount a rubber foot in the middle of the turntable. This will help center the subwoofer on the turntable.
