Why Tradesman DC Brief history Questions and Answers

In the beginning:
We needed a reversing variable speed motor for a new tool grinder.
Jeff , was going to redesign the venerable old CUTTERMASTER The world had changed since 1972 and it needed some help. In 2010 the Cuttermaster Professional was born using a Bodine Motor and control.

We bought one of every motor we could find and arrived at DC being the only thing that would work because of its smooth quiet yet powerful variable speed characteristics.

The control: We designed our own board, but landed correctly on KB electronics KBw16 and KBws25

The Wheels: This is a good story we landed a contract to sharpen 100000 plus tools for Boeing Canada. in 2007 (this started the Tolgrinder design project,I bought 2 Darex M5 drill sharpeners and soon was wearing out super abrasive wheels, so we designed our own in 2008 we now have 50 or so wheels that have been designed to be better than the ancient designs that were available.

Question and answers;

Lets start with this comment from one of our customers:

If an experienced woodturner had a choice of a variable speed lathe or a one-speed lathe, what would he or she choose?

1. What does DC give me, precisely?

a DC motor develops 5 times the torque of an AC motor. In order to be useful through a range of speeds the motor needed to be DC.

2. What does variable speed give me in a grinder, concrete examples?

Higher torque means more material removal at lower speeds preventing excessive heat

3. How, in examples, does the Tradesman’s level of variable speed affect safety?

From a safety perspective having a super quiet controlled spin means you can tell exactly when the tool is in contact with the wheel and how much pressure is involved, The Tradesman spins Tradesman wheels so accurately that the wheel contact is uniform through the full revolution.

4. Who’s behind this grinder? Who’s the inventor? Why did he make what he made the way he made it?

Jeff Toycen Invented the Tradesman Grinder using the same DC motor he developed for the Cuttermaster Professional Tool and Cutter grinder, while on a trip to Florida with his friend Marty Rogers who wanted a better grinder for sharpening his Farm mower blades

5. What’s Tradesman’s level of support, coming from the mouths of those who have experienced it?

If your Tradesman ever needs work Our support is the best in the business

6. Whom can I call who has a Tradesman DC Grinder, to get so-called straight talk from someone who isn’t selling them?

We are always happy to provide names of Happy Tradesman Fans we have a bunch.

7. Super Abrasive wheels the facts

CBN and Diamond Super abrasive wheels that are plated bond, have a layer of .002 to .008 depending on the grit bonded to the grinding surface Meaning the wheel need to run true or it will be destroyed, the flip side of that is when they do run true, at variable speed the grinding process is unrivaled.

8. The grinder is DC does it plug into an ac outlet.

Inside every Tradesman is a 130 Volt DC motor specifically built for out machines, it has a rather expensive Pulsewidth modulated board that converts 120 -240 volts to DC output. The PWM board is much quieter and produces cleaner power than the more common SCR type boards.

Our unique electronics combined with a great deal of engineering care and careful bearing selection is what makes our Tradesman the quietest grinder on the planet and a joy to use.

One of our customers suggested we say this (so we will) 🙂

The Tradesman reeks of “quality” and concern for excellence” and giving the user NEEDED CHOICES in speed.

Georgia Grinding wheel Article

Toycens’ Read on the benefits of aluminum body VS Steel core superabrasive wheels

Lighter

lower transportation costs

store less kinetic energy

better heat dissipation

same or better tensile strength that steel wheels

Better balance

Better accuracy

If the grinder has the torque and smoothness/accuracy of runout the result is longer life and a more accurate grind /finish

Tradesman Edge – Evolving – Blade Sharpening

Jack Plane Blade set here

Fits on all Tradesman grinders utilize that handy Tormek rail.

Worried about your angles? Do you use a felt wheel to cover angle mismatch

We think you should be able to repeat and angle within a few minutes, Grind at a speed appropriate for finishing, no risk of damage, and only need a strop type effort to debur a good piece of steel.

On our Twin Belt machine rough on the left 200 grit, exact angle match on the right with a 600 grit, Debur minimal

With this enhanced freehand approach, the stroke is captive but you won’t get cornered by your set up when doing a long blade or a large curved tip. our supermagnets let you rotate the knife to follow a tip radius

With the Tradesman edge running a 600 grit edge grind at 150 surface feet on machined platens allows for perfectly straight hand-fed angles

With the DC whisper drive, in our shop you can hear the clock ticking in the background while running twin belts, this also means you can hear when the blade contacts the belt.

Just like our tool grinders.

Its a new day

Thrust Flange for Toycen Tradesman 6 and 8

March 1, 2019
No Comments

We do like it when our machines are smooth and quiet, side to side run out is always a challenge

Eliminating the previous snapring and washer assembly (which is never flat)
This new flange protrudes thru the side plate using that normally unutilized shaft length to help govern wheel run out

Plus the larger diameter provides a large driven face to shoulder against.
