The salesperson agreed with me that being a Swiss made product one
would think it would work like a champ. But he also said that it is
just one of those products that seems like a good concept but
unfortunately just isn't designed to work well at all.
This reminds me of the swiss “advanced” or something like that, saw
frame they’ve been selling for the last 20 years or so. Very light
weight, which is comfortable and good. The handle unscrews, good for
storing in small (students, for example) tool boxes. The handle is a
very comfortable foam. All in all, one would expect it to work well.
And with larger size sawblades, it does. But the sawblades fit into
drilled holes at either end of the frame, secured by set screws.
Originally, those screws had plastic wingnut like handles which
broke easily. Now their more like a knurled metal nut. That works
better. But the main problem is simply that the small intense
pressure that small diameter set screw exerts on fine blades (4/0 and
finer) either breaks the fine blades, or more often, simply isn’t
able to hold them. For some reason, they felt they had to improve on
the tried and true clamping system found on the classic german, and
most french sawframes. They missed. Despite several revisions to the
design, it’s still not a great frame. So I stick with the classic
german frames.
On the other hand, whomever in switzerland designed the Badeco
hammer handpiece, got it right. Great tool But their quick change
“holds 3/32 burs” handpiece is good too, but only to a degree. Great
bearings, runs like the proverbial swiss watch, cool, smooth,
accurate, and quiet. But apparently the swiss designers didn’t
realize that there are a lot of attachments one might use in a flex
shaft that are not as accurate in shank size as the Busch or similar
swiss burs. Most mandrels for rubber wheels, mounted brushes, many
other such attachments, or even many high speed steel burs, are
either a hair undersize and the chuck won’t grip it well, or a hair
oversize, and won’t fit in. Boneheaded design, clearly designed by an
engineering department that had not researched actual jewelers tool
use. Kind of a dissapointment for a rather costly quick change
handpiece.
And of course, the fine folks at Pepe tools are champs at this type
of poor design. In fact, they copied that costly Badeco handpiece
with a smaller version with a similar chuck design that they could
then sell for a quarter the price or so. Trouble was, it had the same
problem.
And even here in the U.S., we see such engineering without checking
or testing. We all know and love Kerr’s casting investments, right?
Satin Cast 20 has been with us for a long time, and many use it. So
has their Platinum investment, developed many decades ago. I happened
to be working with a casting company in the mid 90s located not far
from Kerr’s michigan main plant, so we’d be talking not to some sales
rep on the phone, but to their local sales manager when she’d come to
visit (worth her while since we used a lot of investment). About
that time, Gesswein came out with their Supra platinum investment,
and we tried it, and were blown away by how much better the surfaces
were. Almost as clean and smooth as what you expect with gold, while
the Kerr platinum investment produced very rough surfaces every time.
After some discussion, your friendly rep went and did some checking.
Seems that in 40 years of making this stuff, they’d many times poured
a test batch to see how it cured, even fired it to find fireing
temperatures, and strengths, and the like. Typical engineering
tests. But in all that time, they’d never actually invested a wax
model, burned it out, and cast it in platinum. They had no idea that
their formulation used as directed experieced a reaction between the
molten platinum and the investment mold walls that was breaking down
the surfaces causing those rough castings. Just amazing. They’d made
it for decades, and never actually tried using it…
Course, perhaps I’m no better. After decades of now and then making
earrings for pierced ears, I must admit that though others have worn
them, and I pay attention to feedback, I’ve never tried any of my own
pierced earrings on to see how they feel… Not going to either.
Holes in the ears are just not a bit priority for me… (grin)
