Shifter progress

Today I made 12 shifter bodies, have I mentioned how much I love CNC?? Every one is exactly the same, it's incredible. These take around 7 minutes each to do the grooves and turn it down to size.


The past few days  have been busy ones.  Other pics include some shifter pins, this is the lower "pivot" point that goes through the bottom of the shifter, it's held in on either side by two c-clips.  Now they're ready to be hardened and nickel plated.  Third picture is the needle bearing housing, they're stainless steel.  Needle bearing gets pressed into that, then the hardened pins ride on the needle bearing and provide smooth precision shifts!


Next up is some ballscrews that I turned and threaded for my upcoming CNC milling machine conversion.  The new threading tool that I got from Shars kicks butt!  Huge thumbs up.  Last one is a pic of the DCMT 1/32" radius insert that I smoked while turning through the hardened layer of these ballscrews, they're tough! 



Lastly I had to take a bit of meat off the nose of my turbine wheel because it was too long and not letting the nut thread on all the way.  No problem for this machine!  It was easy and turned out perfectly.
