How do you guys make the concave lip to poppers? Thanks.

There are a number of ways to do it, but I think that using a forstner bit is perhaps one of the easier ways to do this.

Click on the link below to see how I do it.

I posted this link below to show you one awesome thing that our own EJTaylor devised (see 5th post) to improve the drilling process.

if you want a cupped face(like those that come on Pop-R's, where the face is cupped inwards, instead of just half-moon shaped like the one in the above links) a round cutting or grinding bit in a dremel works great.

There are several options for making a popper beside the cup-nose.  The simplest way is to leave the front of the lure flat.  Another way that will "spit" water farther is to cut a V-notch in the nose of the bait instead of carving a cup.  Still another option is a variation on the V-notch method where you use a lexan popping lip.  This is probably the most labor-intensive method, but it creates a huge ruckus and throws the most water for it's size.  Below are pics of V-notch and lexan lip poppers.

Hope this helps.

or you can drill a hole out in the front butt, section 1/2 inch or so and put a line tie in there.
