E Glass vs S glass?

[Whatever]

I am a rookie at rod building. Can someone please explain the difference in rod blanks between E-glass and S-glass? Not to technical, please, just the quick and the dirty is fine.

S glass is the higher modulus. E is for inexpensive brute strength. Here’s an explanation:

E glass modulus is around 9 mil, S glass is 12 mil, a bass rod many have used for crankbaits was built on both glasses, the difference in weight was 5/8 oz. So the S glass blank is 24% lighter and 33% higher in modulus.

[Whatever]

In a given weight range (line rating, not physical weight),

is the butt diameter on S Glass rods usually smaller than E Glass?

I am starting my rod building with glass, to save money. I know I will have to build numerous rods to acquire the skills. Right now I am using the $20 spinning blanks from mudhole, but would like to get better blanks if I can afford them. But, honestly, I don't know one from the other.

not really, depends very much on the rod taper and how stiff they want to make the butt - the weight is more dependent on the wall thickness.  

If you have enough strength to resist diameter collapse, thinner wall is geometrically stiffer (greater MOI) than thick wall, and of course larger diameter is also stiffer.  

St. Croix Legend Glass used composite helical wraps to get that diameter-collapse-strength and keep the wall thin.  

Here's my S-glass St. Croix Legend, one of the lightest-weight glass rods I've ever handled, and an MM workhorse. I've mentioned this rod is lighter weight than my IM6 graphite Crowder MM bait rod.  

that's a big Tica Libra SX3000, about the same reel as a Shimano 5000

Bulldog,

When you reference "MM", what does that mean? (and please excuse my ignorance)

[jimmyjoe]

   He means "Medium/Moderate", for medium power and moderate action. And don't be afraid to ask questions. That's how we learn.     ?     jj

Thank you, gents, and I am appreciative of your taking your time to help me out!

I am planning on ordering the actual tools required for rod winding and finishing next month. Currently I am still using a couple of fat auto tech textbooks as a "tensioning device" to wrap guides, and head cement to finish them. With an actual wrapping stand, maybe I can produce a credible product!

MM is the choice rod for kayak fishing in most situations.  

Sitting so close to the water, fishing mostly swimbaits, MM dampens the action you put into the lure just about perfectly.  Also usually tough enough for hard turning to keep a big fish from running under your boat.

Nice rod and reel Short Fish

how's this?

Nice sea trout. I have caught those down in the Florida keys. They are very aggressive!

Are those the ones with the vampire fangs? I used to see Orlando Wilson catch them on TV
