HOW THE COUNTERS ARE MADE

 On the first page of this website the chassis assembly parts may be seen. Three stamped parts are assembled to make the chassis. They are called the chassis, the gear, and the cup. These are the parts that were designed by Tom and ordered from a fabricator – 1000 of each.

 These three parts are held together by a brass grommet, which clamps the cup against the chassis, holding the gear loosely between them. The grommets are a hardware-store item. They come in a package with a striking die to permit the grommet to be properly stamped into place. When the stamping is complete, a chassis assembly is the result.

   

Tom Assembling a Counter

Counters – five or six digit – are purchased from a Veeder-Root supplier. Delrin gears, designed by Tom, are specially fabricated by a local waterjet-cutting firm near Tom’s home. The delrin gear is a press-fit onto the counter shaft.

Final assembly consists of aligning a counter/gear assembly onto a chassis assembly and fastening with screws and locknuts.

 

Each finished JR counter is packaged for shipping with a set of mounting instructions, two washers, and two electrical connectors, should they be required by the customer. Tom usually has ten to twenty units packaged ahead of time, ready for labeling and postage.

When the PayPal order is confirmed, Tom prints the mailing label using PayPal’s software. The software also prints the proper postage onto the label, and sends money to US Postal Service. Typical priority mail shipments can be simply dropped off at any postbox enroute to work. Express mail, and international orders require a trip to the post office during working hours.
