Shor Polishing Motors & Spindles
The threaded shaft motorsBack in the 1950s, shortly after Shor developed the modern polishing systems that are the basic designs for all polishing system today, we worked with Baldor to design the threaded shaft motor. Threaded shaft motor spindles run truer than spindles that are tightened with an allen key. Consequently, they run quieter, are easier to polish with, give a better finish and the motors last longer.
- Motors come with switches and spindles. Each motor has its own unique spindle and, with only a few exceptions, the spindles from one motor are not interchangeable with any other motor. Most motors are "right hand" (RH). That means the shaft and spindle stick out from the right hand side of the motor. On the other hand (please excuse the pun), "visilapping motors" are all "left hand" (LH). Double spindle motors, of course, use both a right hand and a left hand spindle. Right hand and left hand spindles are not interchangeable. RPM 3450.$359.05 to $825.00
Motor SpindlesEach motor has its own unique spindle and, with only a few exceptions, the spindles from one motor are not interchangeable with any other motor. Most motors are "right hand" (RH), though visilapping motors are all "left hand" (LH). Double spindle motors use both a right hand and a left hand spindle. Right hand and left hand spindles are not interchangeable.
- For holding 1/2" arbor hole wheels such as large rubber wheels.$41.67 to $58.33
- $46.75 to $49.60
Spindle MandrelsThe best place to do polishing is at the polishing motor. That may seem obvious, but most jewelers, when polishing with small brushes, buffs and felts, use their flex shaft machines. Poor control, no torque, dirty and messy (not to mention the loss of gold).a flex shaft is not the ideal way to polish. Spindle mandrels screw onto your tapered spindle and accept all the little brushes, felts, buffs etc.
- Brushes with holes can be threaded onto the hardened steel taper, which in turn can be threaded onto a standard tapered spindle. Handy way to use small setting brushes on a polishing motors.$5.00
- Heavy duty for right side. 1/16" diameter screw. For holding miniature buffs, felts, brushes etc. Fits all Right Hand threaded spindles.$3.50
- Invented by Shor in the 1950's, this chuck is still an invaluable tool for holding 3/32" shank brushes, stones, burs, tools etc. Fits on any tapered spindle. Right Hand Thread only.$8.50
