That's actually a really good way to describe what I think might be going on: the majority of the bristles isn't exactly straight down and get deflected to the side given any sort of lube and a slight bit of pressure.
So a good soaking with super hard wax won't make it a little harder toward wear?
Not as far as I've been able to tell. Of the 30 or so different bases I've used them on, most of them are within a point or two of each other at 68D , whether they were just done with CH4 or fresh from out of the base cleaner.
Pray tell me about that meter. Can you tell a sintered from a sintruded, or extruded base with that toy?
Yes. As it turns out the one pair of extruded bases I have handy is 60D, about 8 points lower than the others.
What is is good for?
The cheap ones are fabulous for sorting various urethane skate wheels and RC car tires. The Shore A meters are superb for that.
You could probably use a Shore D to identify cheap vs. decent boot plastic at a ski swap.
Can you tell when a base has been over heated with it?
Haven't tried yet. I will though.
Tell us more about that meter,
It's really just a calibrated steel pin driven into the surface by a spring, with a dial on the other end to show how far the needle went in.
One waits until the needle stabilises for a reading.
It is _conceivably_possible_ that the needle actually penetrates deeper than a hypothetical
"hard" surface wax layer. If so, the fluctuations before the stable value is reached might be of interest.
Did I see fluctuations higher than ~68D before stability? Yes. Sometimes far higher, into the 90D s range.
But then, my hand isn't really that precise at applying steadily increasing pressure without something to rest on. Something with small penetration and high sensitivity might be of use for "wax hardness". Like the type M ones with hydraulic pressure shown here:
