Hi Ken
The advantages of a laminated shaft;
Well , we will start with a natural piece of wood -It grows with a grain - layer upon layer as the tree ages.
Now this natural piece of shaftwood has an unequal strength -it is more flexible bending with the grain and stiffer
bending across the grain . If a shaft has been radially laminated the strength of the shaft has been equalized in all
directions. because the grain in the shaftwood has been manipulated to do that. Please go to our laminated shaft web page
at www.deroocues.com to see pictures.
The result is a very consistent hit quality and the cue ball response is the same as a regular shaft that has similar density
and taper.
Unique to our laminated shaft is that the shaftwood also has a bookmatched grain which equalizes the natural wood tension.
Regarding deflection ;Our laminated shafts generally have no deflection with a cueball to object ball separation of 4 feet
at medium power (even with extreme siding ) . Something that needs to be mentioned here is the importance of the ferrule
material type.What is commonly known in north America as a "Fiber" ferrule - has very good characteristics in reducing
cue ball deflection compared to metal ferrules because of its hardness being more similar to the shaftwood endgrain.
Although our first laminated shaft was built in 1990 it wasn"t really perfected untill about 8 years ago.
Because of the age of Marco Fu's cue , he uses a regular shaft.
Hope this helps.
