This request sounded like a pretty simple task.....but..... I quickly found out it was a lot more involved than just adding a chatter blade to a Big Boy frame.
First I had to add extra ballast to make the Big Boy body run straight, without it's signature tilt, at high speeds....then I had to modify the chatter blade to compensate for the added drag of the much larger, heavier body.
After several attempts and many changes I got a couple working Big Boy sized chatterbaits....these will be tested soon on our annual trip to the north country.
If this testing goes good then I may also add this one to my lure lineup.
