Several years ago I made a DIY Bobber from a wine bottle cork. This durable and low cost DIY Bobber casts better than a traditional spherical bobber and it catches fish! I was recently fishing a spot where the fish were beyond my cast. With some simple tools and a plastic tube, I created a DIY Sliding Bobber.
Making your own sliding bobber is easy. First, drill a hole through the center of a wine bottle cork with a power drill and a drill bit with the diameter of the plastic tube that you are going to use. Second, cut and insert the plastic tube. (I used the empty ink tube from a ball point pen.) Add lastly, add a bobber stop to you line, insert the line into the bobber, add a plastic bead or a another boober stop, and tie your jig or hook.
A sliding bobber will out cast a fixed bobber because all the weight is at the end of the line, which has better aerodynamics. When the bobber hits the water, the jig sinks— which pulls the line through the bobber until the bobber stop.
The DIY Sliding Bobber is now my go-to rig for bobbing because its low cost, durable, long casting, and incredibly effective at catching fish. Thankfully, I have a life-time supply of wine bottle corks that I inherited from my late F.I.L..
