A Matter of Economics
TS-Aligner was a great hit among professional
woodworkers and even some very serious amateurs but most hobbyists just
couldn't afford it. An appeal came from the members of the rec.woodworking
news group for a low cost version of TS-Aligner. So, I set out to design
an alignment tool worthy of the name TS-Aligner at a price that most
woodworkers would find very attractive.
The first step was to determine exactly
what a low cost TS-Aligner would do. So, I posted a message to the rec.woodworking
news group asking people what functions were most important. I also
needed to know how much it should sell for so I proposed some hypothetical
prices for such a tool. The answers came flooding into my email address
and I took each one very seriously.
Design Criteria for TS-Aligner Jr.
- First and foremost it must work! People
expressed a universal disgust for the multitude of stupid plastic
jigs and gadgets that do not work. I translated this to mean:
- It must operate according to standard
metrological principals.
- It must be made from stable materials
that can hold adequate tolerances over a wide range of conditions.
- It must be machined so that the
size and shape of it's parts are accurate uniform.
- It must be durable so that repeated
use does not alter it's performance or accuracy.
- Secondly, it must be easy to use!
One of the great advantages of TS-Aligner is it's ease of use. People
don't use what they don't understand and several people expressed
some hesitation concerning the use of dial indicators. To put it simply,
people didn't want to buy a tool that requires a Ph.D. in Rocket Science!
They wanted clear and concise instructions with pictures explaining
each step of every operation.
- Third, it must be versatile! It must
work on a wide variety of machines for a broad range of operations.
Nobody wants to spend significant money on a tool that works on only
one or two machines for only a few adjustments. I interpreted this
to mean that it must do everything that TS-Aligner does.
- Finally, it must do all this and still
cost less than $100! This would prove to be the most challenging
criteria. In order to be financially viable, TS-Aligner Jr.
must be profitable for both me and the catalog resellers.
Final design decisions for TS-Aligner
Jr.
- The parts would be machined from custom
aluminum extrusions. This saves the expense of the stainless steel
parts used in TS-Aligner. It also saves a lot of expensive time on
the milling machine since the parts will already be close to their
final size and shape. Machining wasn't completely eliminated because
raw extrusions just aren't accurate enough for a measurement tool.
- Aluminum is the material of choice
because it's relatively inexpensive, easy to machine, very stable
and durable. Anodizing would give the aluminum a hard finish that
would prevent oxide from gumming up operation.
- The three bearing miter slot guidance
system used in TS-Aligner would provide smooth and accurate movement
for TS-Aligner Jr. as well. It's an expensive solution but no bar,
no matter how well made, can equal the play free fit and precise,
gliding motion it provides.
- A new way to measure angles was invented.
The vertical motion of TS-Aligner was far too expensive for TS-Aligner
Jr. So, the Angle attachment gage was created. It measures angles
with respect to a fixed reference point over a very precise fixed
distance.
- Just like TS-Aligner, a dial indicator
would be the measurement instrument of choice. But, unlike TS-Aligner,
the dial indicator didn't need to withstand the rigors of an industrial
shop. So, dozens of different samples were evaluated for accuracy
and quality at the lowest possible cost.
- Best of all, costs were carefully
controlled so that TS-Aligner Jr. was delivered for under
$100 (1995 pricing!), making it the best value in precision alignment tools.
To this day it remains extremely cost competitive with models
starting at less than $75. It means high a volume computer
controlled machining philosophy widely known as "crazy efficient".
I'm still making them right here in my own shop in Idaho.
The outstanding results
TS-Aligner Jr. was everything I hoped
for and much more. Download the manual and see for yourself how TS-Aligner
Jr. can help you to get much higher quality results in far less time.
You can now concentrate on your woodworking without being distracted
by frustrating machine alignment and adjustment problems.
You won't find a better value
anywhere! No other precision alignment tool offers as much quality,
versatility, and advanced features as TS-Aligner Jr. And, best of all,
its cost is very competitive with all the others!
