Hello

Does any of you out there have any suggestions on what to use for an engine turning tip/end tool, and any knowledge on speeds of the quill and lubricant.

Thanks in advance

Anthony.

Google rose engine guilloche http://rgmwatches.com/about_rgm/engine_turning.php realy slow 1 rpm is a bit to fast , standard tool angles for the metal being cut .

I tend to use wet and dry 800 grit simply glued onto a bit of nylon bar
Keep the pressure and time constant and use plenty of wd40.Its a messy slow job.

Not the best Iv done
cheers

Cut a round "plug" from a fine grade Garryflex block to fit in a suitable holder. I was told it lasts ages and gives a consistent finish but I've only done tests with it myself so far!

Engine Turning....try: CRAYTEX ABRASIVES....for a complete line of discs, cones, points, etc.  They sell various diameter rubberized, abrasive rods which can be sliced into small sections, glued into a homemade holder and then chucked into a drill press.  Press the abrasive point into the work, creating a circular swirl pattern.  Locate the work on top of a paper lined with a measured grid system to advance the work by precisely measured amounts under the point to keep the pattern from getting sloppy.
