Quality Made in Canada Shooting Star Technology


Here are the answers to the questions we are most frequently asked about CBX. If the answer you seek isn't here, just e-mail us and we will provide the information you want.
How does the BT DRO work?
The BT DRO works by counting the revolutions of a precision pinion on a rack with an optical encoder.

A rack and pinion? How much backlash is there?
There is NO backlash with the BT DRO! The gear is mounted on a small leaf spring, and it is held in mesh with the rack with no backlash.

Is there any wear in the rack/encoder?
The spring that presses the gear into the teeth of the rack is applying a very slight pressure, not enough to amount to any wear.

What is a CBX?
The CBX is an older model of digital readout that we don't make any more. The BT series has replaced it.

I have a CBX. Can I get a new BT readout separately and use my old scales?
Yes! The scales have not changed and are interchangable beyween the CBX and BT display boxes.

Will it fit my machine?
Chances are that it will. Shooting Star Technology has never found a mill or lathe that the BT won't fit on. Check our compatibility list for the machines we know CBX and BT will fit.(We also offer a 30 day money back guarantee, so there would be no problem to return if it didn't fit)

Can I cut the scales to make them fit my machine?
Yes. The rack can easily be cut with a hacksaw to fit your machine.

How do I protect the scale from chips and coolant?
The BT comes with 1/2" wire loom (black, plastic tubing) over the racks. We also suggest you shield it with angle aluminum, or iron, etc. This will protect the scale from any damage from dropping something heavy on it.

Who makes your precision racks and pinions?
We do. Shooting Star Technology uses a custom built CNC machine to cut the racks. The pinions are cut on a #3 Fellows fine pitch gear shaper.

What is the accuracy of the BT?
The accuracy of the BT is 0.002 inch / foot. (Worst case scenario)

What is the resolution of the BT?
The resolution of the BT is 0.0005 inch. (1/2 thou)

What is the repeatability?
The repeatability of the BT is 0.0005 inch. (1/2 thou)

Where is the BT manufactured?
The BT is manufactured in our plant in Rosedale, B.C., Canada. (About 1 1/2 hours east of Vancouver) We manufacture almost every part in one shop, so all of the pieces are readily available.

I'm just a beginner machinist, what if I need help installing the BT?
The BT Digital Display unit includes a manual with mounting considerations, and diagrams. It also shows you step by step how to use all of the features of the unit. However, if you are unsure of mounting, or have any other questions, our technical support staff is very knowledgable, and willing to help you via phone, fax, or email. We are available Monday - Friday 7:30 - 4:00. (Pacific time)

What if I damage my BT?
Shooting Star Technology keeps a stock of all parts of the BT, and we will courier out a replacement for your damaged part usually the same day! There is no waiting for a lengthy factory evaluation, we realize that once you get used to your BT, you don't want to be without it!

I'm from the U.S. Is there any duty on the BT if it crosses the border?
You have no duty or brokerage fees to pay. Since our digital readouts are Made In Canda, they are covered under NAFTA and no duties apply.

How much is shipping?
We charge flat rate shipping of $35 to anywhere in North America!

What kind of warranty does the BT have?
The BT has a 5 year warranty, and a 60 day money back guarantee.

What else does Shooting Star Technology do?
