One step left ...

Since Jim brought up my end mill sharpening fixture in another thread I thought I'd update . Everything is finished except a pin wrench to tighten the collet nut . I used the inside threads in my 5C collets because of tight space and the nut is down in a hole . I spent yesterday afternoon setting up the RT and drilling the index holes in the collet holder . 12 holes which will let me sharpen 2, 3, 4, and 6 flute end mills . Thinking about it now it would have only needed 4 more holes to do 8 flute , but I don't have any so I guess that's moot . The second go-round with the fixture base went much better than the first . I started with a larger block , and milled all the angles after I machined the big hole on the lathe . The bigger block makes for a much more stable tool with more gripping surface in the vise . I also got the mandrel pieces to mount my grinding disc machined this past week . I used my mandrel shaft from the gear cutters , with new parts to adapt the 1.25" hole in the disc with the .863" lower shaft . The upper shaft is .750" since that's the biggest collet my R8 spindle will accept (and I haven't attempted an R8 mandrel shaft yet) . I may need to get a diamond dresser , I think I have about .001 runout on the face . Not bad but probably not quite good enough . We'll see .
