I thought I would show you what I do to the Sea Witch heads that I use for tieing my Sea Witches up with.
The first two pictures are of the 1/4 oz lead head. The 3rd and 4th pictures are of the .5 oz. lead head. The 5th picture is of the .3 oz. Draggin Eyes heads that I use and love. The 6th picture is a picture of all 3 types of heads.
What I have learned since I did this write up last year is, Make sure you drill with the larger bit first. WHY??? I found that when I drilled down in the head with the smaller bit first, it weakened up the back of the head a little bit. So, if you got to close to the edge with the smaller bit....then when you drilled the back out with the larger bit, it would sometimes break the flare off the back of the sea witch. Then, you have wasted a good head.
Another thing is don't try to go much bigger on the bit sizes. I have drilled out a few that I thought were fine.....I later found out when I was tieing on my hair that they were too weak. When I cinched down to tighten the hair up, the back of the head popped off. Once again your left with a wasted head.
With the Lead Sea Witch heads you don't have to put them in a vice. I just hold them in my hand and drill them out over the garbage can. The Draggin Eyes heads are Chrome over brass and much tougher. They need to be put in a vice to drill them.
The bits I use are a 7/32" bit and an 11/64" bit for this. If you want a bigger hole in the back you can go up a size or 2 depending on the head your working with.
I start out with the larger bit first. I drill down about an 1/8" into the head.
Then, I drill with the smaller bit down deeper into the center of the head about another 1/4". The smaller bit gives you your depth for the ballyhoo bill to slide into. The larger bit gives you the ability to run a little bigger ballyhoo and still be able to slide the bill into the head.
What does doing this accomplish?
Well, first off your bait will swim better. It will also track better. A Sea Witch head that is flat on the back...ends up just floating around in front of your bait. When you drill this hole, it allows the nose of the bait to get anchored inside the head so, your Sea Witch and bait are as one.
Sometimes when you troll with wire using a Sea Witch. When you pull it in to check it you will see that the wire is kinked or bent pretty bad right in front of the ballyhoo's nose. That's because the Sea Witch head is moving around in front of the bait instead of being locked in. The preasure of being pulled through the water and jumping out of the water while being trolled is what causes it to kink. Doing this will fix that.
