Star Gauge Star Dex Grinding Indexer Fixture Jacobs 96-F1 Collet Chuck on Sine

Description

Star Gauge Star Dex Grinding Indexer Fixture Jacobs 96-F1 Collet Chuck on Sine.  Partially disassembled and cleaned and lubricated.  There is a lubrication port on fixture.  I counted 36 positions and an approximate center height of 4".  It is stamped 2.500 Angle Sine.  Also stamped Star Gauge Co Springfield Mass.  Serial #4 8-1-64.  I am assuming the last digits are the manufacture date.  Fixture has smooth function.  There are no instructions but it is simple to operate.  There is a knurled handle inside of the handle that is the position locking mechanism.  On the top there is a knob that slides forward to lock the chuck (knob does not appear to be original).  The Jacobs collet chuck takes the rubber flex collets and one is included size J916 3/4-7/8.  I left the collet nose loose but it simply screws off to change collet.  No other collets are included but I believe it would take other Jacobs rubber flex collets in that series which would be J915 5/8 to J920 1 3/8.  May also take the smaller J910 set.  Overall a nice design with a sleeve bearing which can be seen in photos.  I didn't see any shop etchings.  The wood case may need some attention as the sides look to be breaking at the seams.  Please review all photos to determine condition and identification.  Item is sold as is with No Returns.  Will be shipped via UPS Ground.  Will be packed securely.
These are hard to come by and are on the rare side.
