1. Rivett 918s - Added Knurling Capability

    Brown and Sharpe 210-120 Knurling Swing Tool.  Nice addition for the Rivett 918s.  Takes 5/8"OD - 1/4ID - 1/4" Width Knurling Wheels.  Came with the "fine" diamond (male or female tbd).  More wheels to come and and a bit more studying.  Great document for anyone playing with knurling  Reed Machinery - Knurls and Knurling has been a great help.

    The swing tool is interesting.  The swing allows the placement of the knurl on the part to be flexible.  Single wheel limits patterns formed by multiple wheels but diamond patterns available so not a worry.  Initial test shown above - not too shabby.  Need to work on the push bar that contacts the swing arm, just pushed it with the cross feed plate for now.

  2. Riser Plate for Rivett 918s

    Working out a t-slot riser plate for the Rivett.  With the tooling I am using in the turret it is hard if not impossible to get the cut-off tool close enough to spindle and keep the turret from running into the cross-slide.  The t-slot riser plate will allow enough freedom of movement to accommodate the shorter turret tools.

    I have a few Brown and Sharpe Tool Posts for Square Tools - They may be a little big but I am going to figure out a riser plate to mount these with for shits and giggles.

  3. Lamp Finial Prototype

    Small project for the Rivett 918s - Well, nothing is small of course and relieved that the tapping operation for the 1/4 27 "standard/popular lamp harp thread" is working great.  This particular final blank is slated to have hand made marbles (not the ones pictured here - much nicer/larger ones coming soon).

    Working with the Rivett Lathe is the most fun part of this prototype.  Created custom bushing for tapping tool (more on that later) and pleased with the finish on the turning operation.  Used ball end mill for creating concave "marble holder" - will experiment with sizes and such depending on marbles.  Lastly, will certainly change diameters and work on other contours as time permits.
