The first thing you need to do is epoxy the magnets in place. Make sure you put the magnets in the correct way so that they are attracted to each other. If not they will not stick together. (Don’t ask how I know). Mix up your epoxy per the instructions and place a small amount in each of the magnet pockets (enough so some will squeeze out when you put the magnets in). Put the magnets in making sure they are flush with the edge of the shoe. Now fill in the top of the magnets with more epoxy. Try to keep the matting surfaces clean. I used 5 minute epoxy so of course it took about 20 minutes to set.
Once the epoxy is dry enough to handle you can continue to the next step. The best way to assemble the shoe is on the machine. Start by attaching the adjustable mounting bracket to the accessory hole on the side of the spindle mount. Make sure the bottom is flush with the bottom of the spindle mount. No place the PVC pipe in the large part of the dust shoe, (it should fit snug and not need any glue at this time). Place the dust shoe around the spindle body with the PVC pipe up against the adjustable mount bracket. Now slide the ring down over the PVC until it rest on top of the mounting bracket. Once you have everything fit properly I used a little superglue to temporary attach the pieces together. Now very carefully remove the screw holding the dust shoe on and remove the dust shoe. You can now use epoxy to finish bonding everything together.
After your epoxy has dried you can now attach the vinyl skirt. I attached it in one piece and cut the slits in it afterwards. I cut mine down to 2.75" tall but you will have to measure your machine to decide what will work best for you. Always error to the long side, it is easy to trim down on the dust shoe. I ended up with a final height of 2". Use the#6 sheet metal screws about 1" apart to attach the skirt around the entire dust shoe and then cut slits in the skirt where the dust shoe splits apart. I put a drop of super glue at the ends of the skirt where you can’t put a screw due to the magnets. Now cut slits every 1/2" up about half of the height of the vinyl.
You are now ready to use you new dust shoe.
