Available in both AC (no power supply needed) and DC (very torquey, but motor draws 7-8 amps).

 

Now comes standard with a very nice calibration system & ball bearings in the spindle.

 

See post #4 for an explanation.
 
$400 plus shipping.

 

Available to legitimate raceways, at a nice discount.

For those not familiar with the unit, along with the larger diameter, standard size, sanding drums, the beauty of it is the ease of adjustment.
 
Geary uses two identical size drums to set the initial adjustment.
 
If any fine tuning is needed, to get the left and right sides identical, it's simple. Just loosen the two bolts holding the carriage in place.
 
That carriage pivots on the left.
 
On the right side of the unit, with your tire wrench, you turn the angled set screw in or out, until the unit is perfectly parallel to the rotating drums.

I just tried it with a threaded axle off of an old Dynamic Dyna-flex chassis, euipped car, I bought awhile back.
 
I did the switch over, in literally about 10 seconds, from the Koford 1/8 axle that was in my personal 2 True.
 
The threaded axle measured about .123", compared to .124", for the Koford 1/8", so you can feel a minuscule amount of play.

We've had enough demand for calibration for this unit, that Geary and his machinist friend, have come up with a nice system.
 
It is standard equipment, and the truers are now $400 (with newly added ball bearing spindle)

You'll have a letter as a reference, and a 1-5, number suffix.

If you true in a fairly large diameter range, you'll add a number prefix, corresponding to these height lines (which are much easier to spot in person)

Geary has now added ball bearings in the spindle.

 

The retail price has gone up from $380 to $400.

 

For those not aware, I am the distributor of these, and offer legitimate raceways, a discount, 10% higher than what is typically offered on Hudy tire truers.

 

If you are interested in one of these units, and have a local raceway where the owner doesn't pull up in a Ferrari, every day, you should encourage them to order it from me, for you.

I have a new batch of the newest units, with the ball bearing spindle.

All with A/C motors. (no power supply needed)

 

A reminder, these are available to raceways at a discount, 10% better, than your typical Hudy discount from distributors.

 

Support your local raceway, if you have one, and encourage them to order you one, thru me.

These are a huge time saver!  I've had mine for 3 years and it was the best investment I ever made.

2 Trues are now $480 retail.

 

When I get caught up a bit, I will post about the optional coring attachment for those who mount their own rubber.
