This is right.
Dickie, the G in G-10 is for glass. It's not related at all to the G in Garolite.
Another thing to note is the difference between rod and tube.
In almost all applications that you would get through normal channels like McMaster Car, MSC or most plastic companies, the rod you get is what's called "Sheet Rod". Sheet rod is basically a rod that starts as a large sheet. It's then cut into strips and run through a doweler or centerless grinder of some kind to make the rod.
Tube, is almost always wound around a center mandrel and then pressed into a mold. This method usually has issues at the ends, which is why the lengths are always variable. They say it's 48", but it can be as low as 39 or 40. There are solid wound rods, but they can be difficult to find.
If you use sheet rod to make a phenolic tip/ferrule combo, they are prone to splitting along the canvas or linen cloth lines.
The phenolic tips we use on our Speed Break shaft are brown linen phenolic. But, we cut them from a sheet so that the linen cloth is layered like the layers in a regular layered leather tip. That way the impact is constrained by the cloth and can't just split layers of it apart. Tips done this way are bullet proof.
It's also better to use tube or wound rod for any kind of an insert. The reason is that because it's wound, there is uniform wrapping strength all the way around. It does not have that weak spot where the canvas layers can just split apart from each other because the only thing holding it is the resin.
