Hello, I'm wondering if there is a mold to closely replicate the Denny Brauer 4.5" flipping tube with the solid head? Another question is what is the shelf life of plastisol? 

Shelf life.....years.  Just shake it once in a while.

Thanks jig man, that's what I was hoping to hear. Just need a mold to make my bluegill flipping tubes now.

If you already have a mold, use a shorter spline. Any of the companies that sell the molds should be able to make one for you

Ok thanks, I'd imagine I could cut off a half an inch on the rod to get the result I'm looking for. 

The price of a single cavity mold is about all I would be willing to invest in this. Whether it's worth the hassle is what I'll need to consider. 

Cutting off a piece would be your least expensive option
