Drilling Spool

[Rivverrat]

Well if the spool side are heavy walled  ,i would chuck it up in a lath and thin it down some .     
    Take material from the pate side , that will keep dirt and water `from entering the insides .
      You might steal a little weight from the arbor , by drilling little pot holes 1/16 inch deep .

    Joe, I haven't started this project yet. What you describe is how I would go about it. If it works or fails, I have learned something either way & I'm out nothing more than my time & $20 I paid for the not so great spool... Jeff

Well now ...

That looks good to me.

Brendan, I didn't do this. I was just showing this as an example of someone else doing what I'm describing.

  This is a Tiburon TX4N. This how they work their spools on these kits provided by Randy.

  I will make a note here ... my gut is telling me the more weight that can be removed from the outside edge of spool the more dramatic the effects may be... Jeff

Correct.  You are essentially trying build something with the opposite properties of a flywheel.  Flywheels are designed to put as much weight as possible as far from the axis as possible, A classic flywheel is large diameter, narrow, with extra mass around the perimeter.  Which is also why narrow reels don't cast as well, BTW. A bit more like a flywheel. 

Rotational inertia = mass*radius². 

The better spool takes less energy to start tuning, and has less momentum once turning.  We want the line to be pulled off the spool as fast as the payload is moving during the cast.  No more, no less.

  Dave, I agree. It is in fact a flywheel or a fluid filled  vibration damper I was thinking about . Which brought about my thinking this... Jeff
