No I don't but I'm still far from having it perfected so I may have to.I've ordered a Dremel tool which I've been told will make it a lot easier.All the saws,grinders & drill bits various Hardware,Model shops,engineering stores etc have told me will do the job have failed,so if the dremel doesn't work I'm going to give up on jetted lures to.
I reckon all they seem to do is liven the skirt up & lighten the pull on flat faces a bit,but if the holes are less than 5-6mm they do nothing.
I was hoping to make some slightly lighter keel weighted ones beause the yanks/Hawaiians either make them full of lead or none at all(1stpic) , The jetted plunger in the 2nd pic is keel weighted,nylon holes & doesn't need as much speed as the other jet heads.
