Well it is also possible that I am just getting old, and need to have my eyes checked!!
You've seen way too many pies.
None of them were Duff's shafts.
Laminated Shaft by Dufferin

You've seen way too many pies.

If you look close to the lines it seems like it is only the center 4 piece part is laminate and the two outside may be a larger piece of wood. Hope I did'nt start a heated debate on what people have knowledge on cues are, just wanted to know what type value and if they are a common cue. Everyone relax. We are here to help each other, right? Not to see who's Dad can beat up the other kids Dad!
They made a gazillion of them.
They don't have much value b/c of that bastard pin.
Also, I've come across way too 2-piece Dufferins that rattled/buzzed.
They made them fast and cheap.
He's taking offers.
Hi,
Most maple or finished grade plywood has a finish grade laminate on both sides. Generally the center plys are douglas fir.
My lumber supplier laminates plywood sheets in any species to order using the hot glue and pressing technique. I looked for laminated solid maple plywood and came up short for 1 1/8" sizes.
I can believe that someone could laminate strips to make a shaft but some how I don't think cues in the Dufferin price range can justify the individual labor cost per unit. Dufferin doubtless had sheets made and cut them into squares on an assembly line.

There's one thing that you guys are overlooking in your reference to plywood regarding
flat-laminated shafts.
With a flat-lam shaft, the grain of the wood for all of the laminations is oriented
in the same direction, ie, N & S.
With plywood, the orientation is switched with each layer, ie, N/S, next layer, E/W
next layer, N/S and so on & so on. This is done to make the plywood as stiff and strong
as possible. This would be totally unacceptable in a cue's shaft.
This would make the shaft ridiculously stiff with very little (if any) flex.
There would be no 'radial' consistency. Each 90* rotation of the shaft would cause it to play totally different.
Also, every other layer would have end-grain on the face of the shaft.
Your use of the word 'plywood' may have been a convenient metaphor for the moment but
it's obvious that it's continued use is lending itself to the current confusion.
Plywood is not suitable for a shaft.

Actually from what I've understood for many years is that there are different grades of "plywood". Construction grade is the type with the orientation alternated and the type used in shafts is called "instrument grade". HTH
Google strikes again...
LVL - Laminated Veneer Lumber is a type of 'specialized' plywood.

I love how words and definitions get nitpicked to death sometimes, it's quite entertaining.
Plywood, laminate, either one should suffice quite well, no?
So advertise your cues as being made from plywood and see if the term will suffice in that context.
You injured and laid up again Sheldon ?

Dufferin was one of the first companies that Predator approached to make their pie laminated shafts. I know that they decided not to do it but there could have been a few samples made. I however never saw one and I was in their plant monthly for a number of years.
Ha! Good point....
Nah, I'm ready to go riding as soon as the weather dries up. :embarrassed2:
I'm doing a bunch of design work lately, so lots of computer time.
